Chapter 1. Introduction  
This chapter describes the operating specifications, features, and components of  
the IBM® System Storage™ DS3200 storage subsystem (hereafter referred to as  
DS3200 or storage subsystem).  
This chapter also includes an inventory checklist and important information about  
best practices guidelines and product updates for your DS3200.  
Overview  
The IBM System Storage DS3200 storage subsystem is designed to provide  
solutions to meet the needs of departmental and midrange storage requirements,  
delivering high performance and availability, advanced functionality, along with a  
modular and scalable storage capacity design. With direct-attached Serial Attached  
SCSI (SAS) connectivity and support for RAID levels 0, 1, 3, 5, and 6, the DS3200  
provides an internal physical storage capacity that is scalable up to 5.4 TB  
(terabytes) when using 450 GB Serial Attached SCSI (SAS) hard disk drives or up  
to 12.0 TB (terabytes) when using 1000 GB Serial Advanced Technology  
Attachment (SATA) hard disk drives.  
Notes:  
1. RAID 6 uses a P+Q design implementation.  
2. When RAID level 1 is implemented and the number of hard disk drives  
increases to more than two, RAID level 10 is automatically implemented.  
A 2U rack-mountable DS3200 enclosure houses one or two RAID controllers with  
up to four SAS ports per controller for attachment of host servers and storage  
expansion enclosures and up to twelve 3 Gbps SAS or SATA hard disk drives.  
The DS3200 supports attachment of up to three storage expansion enclosures,  
resulting in the capability to connect to up to 48 hard disk drives and enabling  
storage configurations of over 21 TB using 450 GB SAS hard disk drives or 48 TB  
using 1000 GB SATA hard disk drives. The DS3200 supports configurations of SAS  
or SATA disks, or a combination of both types of hard disk drives in the same  
enclosure. Advanced DS3000 storage management and copy service options are  
available for the DS3200, including FlashCopy® and VolumeCopy.  
The DS3200 supports up to three hosts in a redundant direct-attached SAS  
configuration.  
The DS3000 Storage Manager version 10 software is also available for the  
DS3200. This storage-management software is designed to help centralize storage  
management, help simplify partitioning of the DS3000 series storage into as many  
as 32 virtual servers, and strategically allocate storage capacity to maximize  
storage space.  
If firmware and documentation updates are available, you can download them from  
the IBM Web site. The DS3200 might have features that are not described in the  
documentation that comes with the unit, and the documentation might be updated  
occasionally to include information about those features, or technical updates might  
be available to provide additional information that is not included in the DS3200  
documentation.

Best practices guidelines  
To ensure optimal operation of your system, always follow these best practices  
guidelines:  
v Make sure that the storage subsystem is in an optimal state before you shut it  
down. Never turn off the power if any amber LED is lit; be sure to resolve any  
error conditions before you shut down the storage subsystem.  
v Back up the data on your storage drives periodically.  
v To maintain power redundancy, connect the DS3200 right and left power-supply  
units to two independent external power circuits through ac power distribution  
units (PDUs) inside a rack cabinet or directly into external receptacles. Similarly,  
the right and left power supplies of the storage expansion enclosures (such as  
the EXP3000) that are attached to the DS3200 should be connected to the same  
two independent external power circuits as the DS3200. This ensures that the  
DS3200 and all its attached storage expansion enclosures will have power in the  
event that only one power circuit is available. In addition, having all the right or  
all the left power cables connected to the same power circuit enables the  
DS3000 devices in the configuration to power-on simultaneously during an  
unattended restoration of power.  
Note: Do not overload the circuits that power your storage subsystem and  
storage expansion enclosures. Use additional pairs of ac PDUs. See  
Table 1 on page 4 for information about storage subsystem power  
requirements. Contact your technical-support representative for additional  
information.  
v Before any planned system shutdown or after any system additions, removals, or  
modifications (including firmware updates, logical drive creations, storage  
partitioning definitions, hardware changes, and so on), save the storage  
subsystem profile as explained in the DS3000 Storage Manager Version 2  
Installation and User's Guide for your operating system. Save the profile in a  
location other than in the logical drives that are created for the DS3200.  
v During any maintenance or attended power-on procedure, carefully follow the  
power-on sequence that is described in “Turning on the storage subsystem” on  
page 46. Make sure that each component of the storage subsystem is  
powered-on in the correct order during this entire power-on procedure to make  
sure that the controller will be able to optimally access all of the storage  
subsystems.  
v The storage subsystem supports simultaneous power-on to the system  
components; however, you should always follow the power-on sequence that is  
described in “Turning on the storage subsystem” on page 46 during any attended  
power-on procedure.

v A storage subsystem in an optimal state should recover automatically from an  
unexpected shutdown and unattended simultaneous restoration of power to  
system components. After power is restored, call your IBM technical-support  
representative if any of the following conditions occur:  
– The storage subsystem logical drives and subsystems are not displayed in the  
DS3000 Storage Manager Version 2 graphical user interface.  
– The storage subsystem logical drives and subsystems do not come online.  
– The storage subsystem logical drives and subsystems seem to be degraded.  
Storage subsystem components  
The storage subsystem has the following removable components. These  
components, called customer replaceable units (CRUs), are accessible from the  
front or rear of the storage subsystem.  
v Up to twelve 3 Gbps SAS or SATA hard disk drives  
v Up to two RAID controllers  
v Two power supplies  
Disk drives and bezels  
Figure 2 shows the locations of hot-swap disk drives and bezels. The hot-swap  
features enable you to remove and replace SAS or SATA hard disk drives, power  
supplies, and controllers (in a dual-controller storage subsystem) without turning off  
the storage subsystem. You can maintain the availability of the storage subsystem  
while you remove, install, or replace a hot-swap device.  
The hot-swap drive bays that are accessible from the front of the storage  
subsystem are shown in Figure 2.

Filler panel  
The DS3200 comes with filler panels in the drive bays. Before you install a  
hard disk drive, remove the filler panel and save it for future use. Each of  
the 12 drive bays must contain either a filler panel or a hard disk drive.

Figure 4. Bezel (right side)  
The DS3200 supports up to twelve 3 Gbps SAS or SATA hard disk drives, which  
come preinstalled in drive trays. Install drives in the 12 drive bays on the front of  
the storage subsystem. When a drive is installed, the drive and tray bay designation  
is set automatically. The hardware addresses are based on the enclosure ID setting  
on the controller and on the physical locations of the drives in the storage  
subsystem.  
There are no serviceable parts in a drive assembly. If it fails, it must be replaced in  
its entirety (drive, bezel, and tray). When you replace a drive, be sure to order and  
install the correct drive. Using a nonsupported drive causes the drive to be locked  
out by the DS3200 controller firmware.

Attention:  
1. After you remove a drive from a bay, wait 70 seconds to allow the drive to spin  
down before you replace or reseat the drive . Failure to do so might cause  
unpredictable results.  
2. Never hot-swap a drive when its associated green activity LED is flashing or its  
associated amber fault LED is flashing. Hot-swap a drive only when its  
associated amber fault LED is lit continuously or when the drive is inactive and  
its associated green activity LED is not flashing.  
Note: If the hard disk drive that you want to remove is not in a failed or bypass  
state, always use the Storage Manager software either to place the drive in a  
failed state or to place the array that is associated with the drive (or drives)  
in an offline state before you remove the drive from the enclosure.  
Controllers  
The DS3200 has one or two hot-swappable and redundant RAID controllers. The  
controllers are at the rear of the storage subsystem. The left controller is controller  
A, and the right controller is controller B. When the DS3200 has two controllers,  
one controller will continue to operate if the other controller fails.  
The controllers contain the storage subsystem control logic, interface ports, and  
LEDs. A single-controller model comes with one SAS host port and can support two  
additional SAS host ports through an optional SAS host port adapter, which  
provides three SAS host ports on the controller.  
A dual-controller model comes with one SAS host port on each controller; each  
controller can support two additional SAS host ports through an optional SAS host  
port adapter, which provides three SAS host ports on each controller.  
Each controller has one SAS drive expansion port for connecting to the DS3000  
storage expansion enclosures and one Ethernet port for DS3200 subsystem  
management purposes. See Figure 13 on page 23 and Figure 23 on page 35.  
Attention: When a DS3200 has two controllers, the controllers must be identical  
to each other in hardware (part number, DIMM size) and firmware. If you install a  
SAS host port adapter in either controller, you must install an identical SAS host  
port adapter in the other controller.  
The storage management software automatically sets the enclosure ID number for  
the controllers. You can change the enclosure ID setting through the DS3000  
storage management software only. There are no switches on the DS3200 chassis  
to manually set the enclosure ID. Both controller enclosure ID numbers are identical  
under normal operating conditions.

Power supply and fans  
The storage subsystem has two removable power-supply units. Each power-supply  
unit contains one power supply and two fans. The four fans pull air through the  
drives from front to back across the drives.  
The fans provide redundant cooling, which means that if one of the fans in either  
fan housing fails, the remaining fans continue to provide sufficient cooling to  
operate the storage subsystem. The power supplies provide power to the internal  
components by converting incoming ac voltage to dc voltage. If one power supply is  
turned off or malfunctions, the other power supply maintains electrical power to the  
storage subsystem. To preserve the optimal airflow, do not remove a failed  
power-supply unit from the DS3200 chassis until you are ready to replace it with a  
new power-supply unit.

Specifications  
The specifications of the DS3200 are listed in Table 1 on page 4. This section  
provides additional site specifications for the DS3200 storage subsystem. Before  
you install the storage subsystem, you must either make sure that your planned  
installation site meets these requirements or prepare the site so that it does meet  
these requirements. Preparations might involve meeting area requirements,  
environmental requirements, and electrical requirements for DS3200 storage  
subsystem installation, service, and operation.  
Area requirements  
The floor space at the installation site must provide enough strength to support the  
weight of the storage subsystem and associated equipment; sufficient space to  
install, operate, and service the storage subsystem; and sufficient ventilation to  
provide a free flow of air to the unit.  
Dimensions

Temperature and humidity  
Table 1 on page 4 lists the acceptable temperature and humidity ranges in which  
the storage subsystem is designed to operate.  
Notes:  
1. The non-operating environment must not exceed the operating environment  
limits for longer than 60 days.  
2. The storage environment must not exceed the operating environment limits for  
longer than 1 year.  
3. Substantial deviations from the suggested operating range, in either direction, if  
sustained for extended periods of time, will expose the unit to greater risk of  
failure from external causes.  
Electrical requirements  
Consider the following information when you prepare the installation site:  
v Protective ground: Site wiring must include a protective ground connection to  
the ac power source.  
Note: Protective ground is also known as safety ground or chassis ground.  
v Circuit overloading: Power circuits and associated circuit breakers must provide  
sufficient power and overload protection. To prevent possible damage to the unit,  
isolate its power source from large switching loads (such as air conditioning  
motors, elevator motors, and factory loads).  
v Power failures: If a total power failure occurs, the unit automatically performs a  
power-on recovery sequence without operator intervention after power is  
restored.  
Site wiring and power  
The storage subsystem uses wide-ranging redundant power supplies that  
automatically accommodate voltages to the ac power source. The power supplies  
operate within the range of 90 V ac to 264 V ac, at a minimum frequency of 50 Hz  
and a maximum frequency of 60 Hz. The power supplies meet standard voltage  
requirements for operation both inside the U.S.A. and outside the U.S.A. They use  
standard industrial wiring with line-to-neutral or line-to-line power connections.

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
The agency ratings for the DS3200 storage subsystem are 6 amps at 100 V ac and  
2.5 amps at 240 V ac. These are the overall maximum operating currents for this  
system.  
AC power recovery  
After normal power is restored after a total ac power failure, the storage subsystem  
performs power-on recovery procedures automatically without operator intervention.  
Power cords and receptacles  
The storage subsystem comes with two jumper cords that are used to connect to  
the rack PDU. You must purchase the power cords that are applicable for use in a  
typical receptacle in your country. See “Power cords” on page 106 for more  
information.  
Heat output, airflow, and cooling  
Figure 11 shows the intended airflow for the DS3200. Allow at least 30 inches in  
front of the storage subsystem and at least 24 inches behind the storage subsystem  
for service clearance, proper ventilation, and heat dissipation.

Figure 11. DS3200 airflow  
When racks that contain many DS3200 storage subsystems are to be installed  
together, the following requirements must be met to ensure that the DS3200  
storage subsystems are adequately cooled:  
v Air enters at the front of the rack and leaves at the back. To prevent the air that  
is leaving the rack from entering the intake of another piece of equipment, you  
must position the racks in alternate rows, back-to-back and front-to-front. This  
arrangement is known as “cold aisle/hot aisle” and is shown in Figure 12 on page  
16.  
v Where racks are in rows, each rack must touch the rack that is next to it to  
reduce the amount of hot air that can flow around from the back of the rack into  
the intakes of the storage expansion enclosures that are in that rack. Use Suite  
Attach Kits to completely seal any gaps that remain between the racks. For  
details about Suite Attach Kits, contact your IBM marketing representative or  
authorized reseller.  
v Where racks are in rows front-to-front or back-to-back, gaps of at least 122 cm  
(48 in.) must separate the rows across the cold aisle (see Figure 12 on page 16).  
Chapter 1. Introduction 15

v To correct airflow in each rack, the rack filler plates must be installed in unused  
positions. Also, all the gaps in the front of the racks must be sealed, including the  
gaps between the storage subsystems.

Attention  
Before you power-on the storage subsystem, it must contain at least four  
drives. If at least four drives are not installed in each attached storage  
expansion enclosure and in the DS3200 storage subsystem, when you  
power-on the DS3200 and its attached storage expansion enclosures,  
your standard storage partition key might be lost and you must  
regenerate it, using instructions at http://www.ibm.com/storage/fasttkeys/.  
In addition, the resulting insufficient load to the enclosure power supplies  
might cause them to intermittently appear to have failed, falsely indicating  
that the power supplies are bad. All drives in the DS3200 storage  
subsystem and the connected storage expansion enclosures must  
contain no prior configuration data.  
7. Use SAS cables to cable the DS3200 to the storage expansion enclosures.  
See “Connecting storage expansion enclosures to the DS3200” on page 26.  
8. Complete one of the following cabling tasks to enable management of the  
DS3200 configuration:  
v If you are using out-of-band management, cable the DS3200 Ethernet ports  
to either the management workstation or the host.  
v If you are using in-band management, cable the DS3200 hosts to the SAS  
host bus adapters (HBAs) in the hosts. See “Connecting hosts to the  
DS3200” on page 37.  
9. Connect the power cables for the DS3200. See “Cabling the DS3200 power  
supplies” on page 43.  
10. Power-on the attached storage expansion enclosure and the DS3200 storage  
subsystem, using the procedure in “Turning on the storage subsystem” on  
page 46.  
11. Install the DS3000 Storage Manager Version 2 software on the management  
workstation (for out-of-band management) or on the host (for in-band  
management). See the IBM System Storage DS3000 Storage Manager 2  
Installation and Support Guide for the management-workstation or host  
operating system for instructions for installing the DS3000 Storage Manager  
Version 2 software.  
12. Use the DS3000 Storage Manager software to verify the configuration.  
13. Review and perform the procedures in “Performing the DS3000 Health Check  
process” on page 45.  
Handling static-sensitive devices  
Attention: Static electricity can damage the storage subsystem and other  
electronic devices. To avoid damage, keep static-sensitive devices in their  
static-protective packages until you are ready to install them.  
To reduce the possibility of electrostatic discharge, observe the following  
precautions:  
v Limit your movement. Movement can cause static electricity to build up around  
you.  
v Handle the device carefully, holding it by its edges or its frame.  
v Do not touch solder joints, pins, or exposed printed circuitry.  
v Do not leave the device where others can handle and damage it.  
Chapter 2. Installing the storage subsystem 19  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
v While the device is still in its static-protective package, touch it to an unpainted  
metal part of the system unit for at least 2 seconds. This drains static electricity  
from the package and from your body.  
v Remove the device from its package and install it directly into your system unit  
without setting it down. If it is necessary to set down the device, put it back into  
its static-protective package. Do not place the device on your system unit cover  
or on a metal surface.  
v Take additional care when you handle devices during cold weather. Heating  
reduces indoor humidity and increases static electricity.  
Preparing for installation  
Before you install the DS3200 storage subsystem, create a detailed plan of how this  
unit will be used in your storage configuration. The plan should include determining  
RAID levels, failover requirements, operating systems that are to be used, and total  
storage capacity requirements.  
To prepare the DS3200 storage subsystem for installation into a rack cabinet,  
complete the following steps:  
1. Prepare the site to meet all area, environmental, power, and site requirements.  
For more information, see “Specifications” on page 13.  
2. Move the shipping box that contains the DS3200 to the site.

Enclosure ID settings  
The controller automatically sets the enclosure ID number. You can change the  
setting through the storage management software, if necessary. Both controller  
enclosure ID numbers are identical under normal operating conditions.  
The allowable range of enclosure ID settings is 0 through 99. However, for best  
results, do not set the enclosure ID to 00 or any number less than 80. The DS3200  
enclosure ID is normally set to a value of 85 at the factory.  
Working with SAS cables  
Each DS3200 RAID controller has up to three x4 multilane SAS host ports and a  
single x4 multilane SAS port for drive channel connections.  
Use a 1M or 3M (1-meter or 3-meter) SAS cable with a mini-SAS 4x multilane SAS  
connector on each end to connect a controller host port to a host HBA and to  
connect the drive expansion port to a storage expansion enclosure.  
The following illustration shows the 1M and 3M mini-SAS cable.  
Mini-SAS  
connectors

Attention: To avoid damage to the SAS cables, consider the following  
precautions:  
v When you route the cable along a folding cable-management arm, leave enough  
slack in the cable.  
v Route the cable away from places where it can be damaged by other devices in  
the rack cabinet.  
v Do not put excess weight on the cable at the connection point. Make sure that  
the cable is well supported.  
To connect a mini-SAS cable, insert the mini-SAS connector into a mini-SAS port.  
Make sure that it locks into place.

Connecting storage expansion enclosures to the DS3200  
Attention  
Before you power-on the storage subsystem, it must contain at least four  
drives. If at least four drives are not installed in each attached storage  
expansion enclosure and in the DS3200 storage subsystem, when you  
power-on the DS3200 and its attached storage expansion enclosures, your  
standard storage partition key might be lost and must be regenerated, using  
instructions at http://www.ibm.com/storage/fasttkeys/.  
In addition, the resulting insufficient load to the enclosure power supplies  
might cause them to intermittently appear to have failed, falsely indicating that  
the power supplies are bad. All drives in the DS3200 storage subsystem and  
the connected storage expansion enclosure or enclosures must contain no  
prior configuration data.  
In the initial installation of the DS3200, you can add only new storage expansion  
enclosures to the DS3200 storage subsystem. This means that there must be no  
existing configuration information about the storage expansion enclosures that you  
want to install.  
Note: In this document, EXP3000 storage expansion enclosures are used as  
examples in text and illustrations.  
If the storage expansion enclosures that you want to install currently contain logical  
drives or configured hot spares and you want them to be part of the DS3200  
storage subsystem configuration, see the IBM DS3000 Storage Manager Version 2

Redundant drive channel pair  
Each RAID controller on the DS3200 has a drive expansion channel that contains  
an x4 SAS port. The storage expansion enclosures that are connected to this  
connector form a drive channel. The maximum number of hard disk drives that can  
be installed in one drive channel is 48. In a dual-controller DS3200, one drive  
channel from each controller combines to form a redundant drive-channel pair.  
Figure 18 shows an example of a redundant drive-channel pair. If any component of  
the drive channel fails, the RAID controllers can still access the storage expansion  
enclosures in the redundant drive-channel pair.  
Note: In storage expansion enclosures that are connected to a dual-controller  
storage subsystem, you must install the optional second ESM to support  
dual redundant drive paths.

Overview of steps to connect storage expansion enclosures to a  
storage subsystem  
To connect storage expansion enclosures to the storage subsystem, complete the  
following steps:  
1. Follow the instructions in the Installation, User's, and Maintenance Guide for  
your storage expansion enclosure and the Rack Installation Instructions to set  
up and mount the storage expansion enclosures.  
2. Select a cabling topology applicable to the number of ESMs in the storage  
expansion enclosures that you will connect to the DS3200. If you are connecting  
external storage expansion enclosures to the DS3200, make sure that each  
storage expansion enclosure contains at least four drives before you power it  
on. In addition, make sure that the DS3200 storage subsystem contains at least  
four drives before you power it on.  
“DS3200 storage subsystem drive cabling topologies” describes the  
recommended schemes for cabling storage expansion enclosures with one ESM  
or two ESMs to the DS3200 and to each other (if you are connecting more than  
one storage expansion enclosure).  
3. Follow the cabling diagram for your chosen topology.  
4. If required, set unique enclosure IDs for all storage expansion enclosures that  
are cabled to the DS3200. See the DS3000 Storage Manager Version 2  
Installation and Support Guide for information about setting the enclosure ID.  
The DS3200 storage subsystem locates the drives in the storage expansion  
enclosures after you power-on the configuration. Always turn on the storage  
expansion enclosures first and then turn on the DS3200. After you have  
powered-on the configuration, use the DS3000 Storage Manager software to check  
the status of the new drives, correct any errors, and configure the new drives.  
DS3200 storage subsystem drive cabling topologies  
This section describes the following preferred cabling topologies for cabling storage  
expansion enclosures to the DS3200 storage subsystem:  
v “One single-controller DS3200 and one or more storage expansion enclosures”  
on page 29  
v “One dual-controller DS3200 and one storage expansion enclosure” on page 30  
v “One dual-controller DS3200 and two storage expansion enclosures” on page 30  
v “One dual-controller DS3200 and three storage expansion enclosures” on page  
31  
Each example provides redundant paths to the drives. If one of these examples is  
suitable for your hardware and application, complete the cabling connections as  
shown in the illustrations. If you have hardware other than what is shown in these  
examples to include in your topology, use these examples as a starting point for  
creating your specific topology.  
Important:  
1. The DS3200 supports the connection of a maximum of three storage expansion  
enclosures.  
2. The DS3200 supports one redundant drive-channel pair.  
3. In storage expansion enclosures that are connected to a dual-controller storage  
subsystem, you must install the optional second ESM to support dual redundant  
drive paths.

Adding a storage expansion enclosure to a dual-controller  
configuration that is running  
The following procedures provide instructions for adding storage expansion  
enclosures to a dual-controller DS3200 storage subsystem that is running.  
Note: Make sure that each storage expansion enclosure has two ESMs before you  
connect it to a dual-controller DS3200 storage subsystem. The second ESM  
must be purchased separately. Contact your IBM marketing representative or  
authorized reseller for more information about purchasing a second ESM.  
For more information about installing a second ESM, see the Installation  
Guide that comes with the storage expansion enclosure.  
To add a storage expansion enclosure to a dual-controller DS3200 storage  
subsystem that is running, complete the following steps:  
1. Make sure that the DS3200 storage subsystem status is Optimal in the  
Storage Manager software.  
2. Use the storage expansion enclosure Rack Installation Instructions document  
to install the new storage expansion enclosure in the rack.  
3. Connect the power cables to the new storage expansion enclosure.

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
4. Power-on the storage expansion enclosure.  
5. Connect one end of a Serial Attached SCSI (SAS) cable to the Drive  
expansion port on Controller A in the DS3200 storage subsystem.  
6. Connect the other end of the SAS cable to the In port on the left ESM in the  
storage expansion enclosure.  
7. Connect one end of a second SAS cable to the Drive expansion port on  
Controller B in the DS3200 storage subsystem.  
8. Connect the other end of the second SAS cable to the In port on the right  
ESM in the storage expansion enclosure.  
9. Wait until the DS3200 storage subsystem status is Optimal in the Storage  
Manager software before proceeding to step 10.  
10. Add the hard disk drives to the storage expansion enclosure. Make sure that  
you wait at least 30 seconds for the Storage Manager software to recognize  
each newly added drive before you install another drive.  
To add additional storage expansion enclosures after the first expansion unit is  
connected to a dual-controller DS3200 storage subsystem that is running, complete  
the following steps:  
1. Make sure that the DS3200 storage subsystem status is Optimal in the  
Storage Manager software.  
2. Use the storage expansion enclosure Rack Installation Instructions document  
to install the new storage expansion enclosure in the rack.  
3. Connect the power cables to the new storage expansion enclosure.  
4. Power on the storage expansion enclosure.  
5. Connect one end of a Serial Attached SCSI (SAS) cable to the In port on the  
left ESM in the storage expansion enclosure that is being added to the  
configuration.  
6. Connect the other end of the SAS cable to the Out port on the left ESM in the  
last storage expansion enclosure in the configuration (this storage expansion  
enclosure is directly connected to the Drive expansion port on controller A of  
the DS3200).  
7. On the last storage expansion enclosure in the configuration, disconnect the  
SAS cable from the In port on the right ESM and connect it to the In port on  
the right ESM on the new storage expansion enclosure that is being added to  
the configuration.  
Note: When the SAS cable is disconnected in step 7, a loss of path  
redundancy occurs and an error message is displayed in the Storage  
Manager Recovery GURU. Disregard the error message. The redundant  
path is restored in step 8 after the SAS cable is connected.  
8. Connect a SAS cable to the Out port on the right ESM of the new storage  
expansion enclosure and connect the other end to the In port on the right ESM  
in the storage expansion enclosure that was previously connected to controller  
B of the DS3200.  
9. Wait until the DS3200 storage subsystem status is Optimal in the Storage  
Manager software before proceeding to step 10.  
10. Add the hard disk drives to the storage expansion enclosure. Make sure that  
you wait at least 30 seconds for the Storage Manager software to recognize  
each newly added drive before you install another drive.

Upgrading a single-controller to a dual-controller when there is no  
attached EXP3000 enclosure  
If you are upgrading a single-controller DS3200 storage subsystem to a  
dual-controller DS3200 storage subsystem and there are no EXP3000 storage  
expansion enclosures attached to the DS3200 storage subsystem, see “Installing a  
controller” on page 64.  
Upgrading a single-controller to a dual-controller when there is one or  
more EXP3000 enclosures attached to the storage subsystem  
Before you upgrade the DS3200 storage subsystem from a single-controller to a  
dual-controller, make sure that:  
v You purchase a second environmental services module (ESM) for each EXP3000  
storage expansion enclosure that is attached to the DS3200 storage subsystem.  
You install the second ESM during this procedure.  
v You purchase the SAS cables that are required to create a redundant drive  
enclosure path.  
To upgrade a single-controller DS3200 storage subsystem to a dual-controller  
DS3200 storage subsystem when there are EXP3000 storage expansion enclosures  
attached to the DS3200, complete the following steps:  
1. Turn off the DS3200 storage subsystem and all attached EXP3000 storage  
expansion enclosures.  
2. Install a second RAID controller in the DS3200 storage subsystem by using the  
instructions in “Installing a controller” on page 64.  
3. Install a second ESM in each EXP3000 that is connected to the DS3200  
storage subsystem:  
a. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
b. Remove the ESM filler panel from the rightmost ESM bay of the EXP3000:  
1) On the left side of the ESM filler panel, press the orange release tab to  
the right just enough to release the handle (no more than 6 mm  
[0.25 in.]) as you rotate the handle upward.  
2) Using the handle, gently slide the ESM filler panel out of the EXP3000.  
Save the ESM filler panel for future use.  
c. Hold the new ESM so that the handle is fully extended.  
d. Gently slide the ESM into the bay until it stops. Rotate the handle downward  
into the closed position until it clicks.  
4. Using the information provided in “DS3200 storage subsystem drive cabling  
topologies” on page 28, use SAS cables to create a redundant drive-channel  
path from the DS3200 RAID controllers to the EXP3000 ESMs.  
Connecting secondary interface cables  
This section applies to direct (out-of-band) management configurations only. If your  
configuration uses host-agent (in-band) management, skip this section.  
Use the Ethernet management port on the rear of the storage subsystem to connect  
the controllers for direct management of the storage subsystems (see “Direct  
(out-of-band) management method” on page 36).

Important:  
1. To minimize security risks, do not connect the DS3200 to a public LAN or public  
subnet. Use a local private network for the DS3200 and the management  
station Ethernet connectors.  
2. For proper EMI shielding, always use quality braided and shielded serial cables.

Configuring the storage subsystem  
You must configure the storage subsystem after you install the storage subsystem  
in a rack cabinet. Use the information in the following sections to configure your  
storage subsystem.  
Storage subsystem management methods  
Before you configure the storage subsystem, determine which method of storage  
subsystem management you want to use. You can manage the storage subsystems  
in either of two ways: host-agent (in-band) management or direct (out-of-band)  
management.  
Note: For information about any in-band limitations or restrictions that are  
associated with particular combinations of controller and host bus adapter,  
see the DS3000 Storage Manager Version 2 readme file.  
For more information about setting up in-band or out-of-band management  
connections, see the DS3000 Storage Manager Version 2 Installation and Support  
Guide for the operating system of the host server that you will use to manage the  
DS3200 storage subsystem. The Installation and Support Guide is in the  
Documentation folder on the IBM System Storage DS3000 Support CD.  
Important: If the operating system of the host server that the storage subsystem  
logical drives are mapped to is not Microsoft Windows 2000 or  
Windows Server 2003, you must make a direct (out-of-band)  
management connection to the storage subsystem to set the correct  
host type first. Then, the server will be able to recognize the storage  
subsystem correctly for host-agent (in-band) management.  
Chapter 3. Cabling the storage subsystem 35  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Host-agent (in-band) management method  
This method requires that host-agent software be installed on the host server. The  
host-agent software enables the DS3000 Storage Manager client program to  
manage the DS3200 storage subsystem by using the same connections between  
the host server and the storage subsystem. You must install at least one  
management station and a software agent host. The management station can be  
the host or a workstation on the Ethernet network. The client software is installed  
on the management station. Figure 24 shows the host-agent (in-band) management  
method.

Figure 24. Host-agent (in-band) managed storage subsystems  
Direct (out-of-band) management method  
This method uses Ethernet connections from a management station to each  
controller in the storage subsystem. You must install at least one management  
station. The management station can be the host or a workstation on the Ethernet  
network. The client software is installed on the management station. Attach Ethernet  
cables to each management station (one pair per storage subsystem). You will  
connect the cables to each storage subsystem controller later when you install the  
storage subsystem. Figure 25 on page 37 shows the direct (out-of-band)  
management method.  
Note: Do not connect the DS3200 storage subsystem Ethernet ports to a public  
network or public subnet. To minimize security risks, create a private network  
between the DS3200 storage subsystem and the management station.

Installing the storage subsystem configuration  
Using the information from the previous sections, install the host systems and host  
bus adapters (HBAs).  
Notes:  
1. See the documentation that comes with the HBAs for installation requirements  
and procedures.  
2. Use the correct HBA device driver. For the latest supported HBAs and device  
drivers, go to http://www.ibm.com/servers/storage/support/disk/  
Attach a SAS cable to each HBA. Continue to “Connecting hosts to the DS3200” to  
connect the other end of each cable to a controller.  
Connecting hosts to the DS3200  
The DS3200 can support up to fourteen hosts when attached to the SAS  
Connectivity Module for IBM BladeCenter and up to three hosts in a direct attached  
host environment. The number of supported hosts depends on the number of host  
ports installed on the DS3200 RAID controller. To protect against the loss of any  
one path from the host servers to the DS3200 storage subsystem, use redundant  
host connections.  
Note: In a single-controller storage subsystem, the use of redundant host  
connections is possible only when the optional SAS host port adapter is  
installed in the controller. This provides path failover but limits the number of  
redundant host connections to one.

To connect a SAS host bus adapter (HBA) to the DS3200 storage subsystem,  
complete the following steps:  
1. Connect a SAS cable from the DS3200 RAID controller host port to the SAS  
HBA that is in the host. Figure 13 on page 23 shows the location of the DS3200  
host ports.  
2. Create a redundant host connection:  
v If the DS3200 is a single-controller storage subsystem, connect a SAS cable  
from the second SAS HBA to another host port on the DS3200 RAID  
controller. You can create a maximum of one redundant host connection to a  
single-controller DS3200.  
v If the DS3200 is a dual-controller storage subsystem, connect a SAS cable  
from the second SAS HBA to a host port on the other RAID controller on the  
DS3200. You can create a maximum of three redundant host connections to  
a dual-controller DS3200.  
See “Direct-attached single-controller connections” and “Direct-attached  
dual-controller connections” on page 40 for illustrations of host connections.

Overview of installing an IBM BladeCenter configuration to connect to  
a DS3200  
This section gives an overview and guidelines for installing an IBM BladeCenter  
configuration to connect to a DS3200.  
Before you install the BladeCenter configuration, consider the following information:  
v Make sure that the BladeCenter chassis, blade server, SAS connectivity module,  
and SAS expansion card are supported. Go to http://www.ibm.com/servers/  
storage/support/disk/, select the link for the DS3200, and see the interoperability  
matrix.  
v Make sure that an Advanced Management Module is installed in the BladeCenter  
chassis. The latest level of management-module firmware is available at  
http://www.ibm.com/bladecenter/.  
v For the latest SAS connectivity module firmware, SAS expansion card firmware,  
blade server BIOS code, and device drivers, see http://www.ibm.com/systems/  
support/.  
Installing the BladeCenter configuration  
To install the IBM BladeCenter SAS Expansion Card (CFFv), IBM BladeCenter SAS  
Connectivity Module, and blade server, complete the following general steps:  
1. Install an IBM BladeCenter SAS Expansion Card (CFFv) in each blade server  
that you want to connect to the DS3200. See the documentation that comes  
with the SAS expansion card for installation requirements and procedures.  
2. Install the blade servers in the BladeCenter chassis. See the documentation that  
comes with the blade server for installation requirements and procedures.

3. Install the IBM BladeCenter SAS Connectivity Modules in the I/O bays in  
BladeCenter unit. See the documentation that comes with the SAS connectivity  
modules for installation requirements and procedures.  
4. Go to “Connecting BladeCenter hosts to the DS3200.”  
Connecting BladeCenter hosts to the DS3200  
The dual-controller DS3200 comes with one SAS host connector on each controller,  
enabling up to 14 blade servers in one BladeCenter unit to be redundantly  
connected to the DS3200.  
To protect against the loss of any one path from the host blade servers to the  
DS3200, use redundant host connections. Figure 31 shows the locations of  
controllers A and B and the host connectors at the rear of the DS3200.  
Figure 31. DS3200 controller connectors  
To connect a SAS expansion card that is installed in a blade server to the DS3200,  
complete the following steps:  
1. Connect a SAS cable from the SAS host connector on the DS3200 RAID  
controller to any SAS port on an IBM BladeCenter SAS Connectivity Module  
that is installed in a BladeCenter unit.  
Attention: The optional SAS host port adapter with its two additional SAS  
connectors is not supported in this configuration. You must use the SAS host  
connector on the controller.  
2. To create a redundant host connection, connect a SAS cable from a second  
SAS connectivity module to a host connector on the other RAID controller in the  
DS3200. You can create a maximum of two redundant host connections in a  
dual-controller DS3200.  
Attention: You can connect only one DS3200 to the BladeCenter SAS  
Connectivity Module. No other external devices can be connected to the SAS  
connectivity module.  
3. (Optional) For additional storage, you can connect EXP3000 storage expansion  
enclosures to the DS3200. For an illustration showing how to configure the  
storage expansion enclosures, see Figure 18 on page 27.

Chapter 4. Operating the storage subsystem  
This chapter describes operating procedures for the DS3200.  
To ensure optimal operation of the storage subsystem, see “Best practices  
guidelines” on page 6.  
Performing the DS3000 Health Check process  
The DS3000 Health Check process is a sequence of suggested actions that were  
developed by IBM to help you verify and maintain the optimal performance of the  
DS3200 storage configuration. The information that you collect in these steps also  
helps provide IBM Service with important information that is needed during a  
service call.  
Perform the following Health Check tasks after the initial configuration of the  
DS3200 storage subsystems and after all configuration sessions. Set a regular  
schedule of periodic Health Check evaluations to keep the DS3200 code current  
and to preserve optimal data access and performance.  
1. Monitor the Recovery Guru in the Storage Manager software for any obvious  
storage subsystem errors or problem conditions.  
2. Gather and save the following DS3200 storage subsystem event logs for review  
by IBM Service. These event logs should be gathered periodically for regular  
Health Check monitoring regardless of the state of the Recovery Guru. (You can  
collect all these logs at once and compress them into a single file by clicking the  
Support tab and then Gather Support Information in the DS3000 Storage  
Manager Subsystem Management window.)  
v DS3200 storage subsystem management event log (MEL)  
v Storage Subsystem Profile or DS3200 Profile  
v SAS PHY error log  
In addition, you should also collect event logs for the host servers that have  
mapped logical drives from the storage subsystem.  
Attention: Save these event-log files to a server disk that will remain  
accessible in the event of a DS3200 storage configuration failure. Do not save  
these event log files only to a LUN in the DS3200 storage subsystem.  
3. Use the Storage Subsystem Profile or DS3200 Profile to make sure that the  
following firmware levels are at the latest versions that the DS3200 storage  
subsystem supports:  
v Controller firmware  
v ESM firmware  
v Drive firmware  
If the firmware is not up-to-date, upgrade the firmware and software to the latest  
level that is applicable to the DS3200 storage configuration. See “Overview” on  
page 1 for information about where to find the latest firmware and software.  
Attention: You must resolve Recovery Guru errors or problems before you  
upgrade firmware.  
Save the storage subsystem profile before you perform any controller or ESM  
firmware upgrades. Save the storage subsystem profile and all .cfg files to a  
server disk that will remain accessible in the event of a DS3200 storage  
configuration failure.

4. Use the Storage Subsystem Profile or DS3000 Profile to make sure that the  
following functions are enabled:  
v For all DS3000 models, enable Media Scan both at the controller level and at  
the LUN level.  
v For all DS3000 models, enable the read/write cache. In addition, use the  
Storage Subsystem Profile to make sure that cache is matched between the  
controllers.  
Hardware inspection  
In addition to the Health Check process, regular hardware inspection and  
maintenance helps to support the optimal performance of the DS3200 storage  
configuration. Periodically inspect the components of the DS3200 storage  
configuration.  
For best results, follow these guidelines:  
v Maintain an up-to-date storage subsystem profile for the DS3200 storage  
configuration. Save the profile to a server disk that will remain accessible in case  
of a DS3200 storage configuration failure. Do not save the profile only to a LUN  
in the DS3200 storage subsystem.  
v Develop a change-management plan. The plan should include schedules for  
updating subsystem firmware and server host software.  
Note: Some updates might require storage subsystem downtime.  
v Use applicable IBM-approved cables for all situations. Note in the configuration  
documentation whether any cables are not IBM-approved.  
v Create and maintain a cabling diagram of the current configuration. Keep this  
diagram updated as you make configuration changes, and keep the cabling  
diagram available for review.  
v Create and maintain a list of other components that are being used within the  
cabling diagram (such as the host system and other attached devices).  
v Make sure that all controllers and ESMs are correctly seated.  
v Make sure that all drives are correctly seated.  
v Make sure that cables are managed correctly.  
v Ensure proper air flow and temperature for all components in the storage  
configuration.  
You can find details about many of these inspection and maintenance  
responsibilities in the applicable sections of this document.  
In addition to these inspection and maintenance responsibilities, conduct DS3200  
training for staff that support DS3200 storage configurations. Although training is not  
a part of the Health Check process, training reduces the potential for configuration  
problems and contributes to the correct operation of the system.  
Turning on the storage subsystem  
This section contains instructions for turning on the storage subsystem under  
normal situations. “Turning off the storage subsystem” on page 55 contains  
instructions for turning off the storage subsystem under normal and emergency  
situations. When you turn on and turn off the DS3200, be sure to use the startup  
sequence that is described in this section. If you are turning on the storage  
subsystem after an emergency shutdown or power outage, see “Restoring power  
after an unexpected shutdown” on page 57.

The following procedure addresses two situations:  
v The entire storage subsystem has been shut down (the main circuit breakers for  
the rack cabinet are off).  
v Some storage expansion enclosures are being powered-on while others remain  
online (the main circuit breakers for the rack cabinet are on). You might  
encounter this if you are adding a storage expansion enclosure to increase  
storage capacity.  
Attention:  
1. Repeatedly turning the power off and on without waiting for the drives to spin  
down can damage the drives. Always wait at least 70 seconds after you turn  
off the power before you turn it on again.  
2. If you are connecting a power cord to a DS3200 or storage expansion  
enclosure, turn off both of its power switches first. If the main circuit breaker  
is off, make sure that both power switches are off on each storage expansion  
enclosure in the rack cabinet before you turn on the main circuit breakers.  
1. Are the main circuit breakers turned on?  
v Yes: Turn off both power switches on each enclosure that you intend to  
connect to the power.  
v No: Turn off both power switches on all enclosures in the storage subsystem.  
2. Make sure that all power cords are connected.  
Note: If the power cords are not connected, turn off both power switches on all  
modules in the configuration before you connect power cords or turn on  
the main circuit breakers.  
3. If the main circuit breakers are turned off, turn them on.  
Attention: You must turn on power to each attached storage expansion  
enclosure before you turn on power to the DS3200 so that the controllers  
recognize all drives in the configuration during the startup process.  
4. Turn on both power switches on the rear of each storage expansion enclosure  
that is attached to the storage subsystem. While each storage expansion  
enclosure powers up, the green and amber LEDs on the front and rear of the  
storage expansion enclosure turn on and off intermittently. Depending on the  
configuration, it can take several minutes for each storage expansion enclosure  
to power-on.  
Check the LEDs on the front and rear of all the storage expansion enclosures.  
Make sure that no amber LEDs are lit on any of the storage expansion  
enclosures.  
5. Turn on both ac power switches on the rear of the storage subsystem. Figure 33  
shows the locations of the ac power switches on the DS3200.

each storage enclosure powers-on, the green and amber LEDs on the front and  
rear of the storage expansion enclosure turn on and off intermittently. The cache  
battery backup self-test might take up to an additional 15 minutes to be  
completed. During this time, the LEDs on the front and rear of the storage  
subsystem might flash intermittently.  
6. Determine the status of all storage subsystems and components in the  
configuration by completing the following steps:  
a. Check all LEDs on each component in the storage expansion enclosures.  
Make sure that all the LEDs show normal status. For more information about  
LED status for storage expansion enclosures, see “Checking the LEDs” on  
page 52 or the Installation, User’s, and Maintenance Guide for the storage  
expansion enclosure.  
b. Check all LEDs on each component in the storage subsystem. Make sure  
that all the LEDs show normal status. For information about LED status, see  
Chapter 6, “Solving problems,” on page 99.  
c. Open the DS3000 Storage Manager Subsystem Management window, and  
display the status of the storage subsystem.  
7. Are the LEDs indicating normal operation, and is the status Optimal on all the  
configuration components?  
v Yes: The procedure is complete.  
v No: Go to step 8.  
8. Diagnose and correct the fault by completing the following steps:  
a. Run the DS3000 Storage Manager Recovery Guru by clicking Recovery  
Guru in the Subsystem Management window toolbar.  
b. Complete the recovery procedure.  
If the Recovery Guru directs you to replace a failed component, use the  
individual LEDs on the storage subsystem to locate the specific failed  
component. For troubleshooting procedures, see Chapter 6, “Solving  
problems,” on page 99.  
c. When the recovery procedure is completed, select Recheck in the Recovery  
Guru. This action runs the Recovery Guru again to make sure that the  
problem is corrected.  
d. If the problem remains, contact your IBM technical-support representative.

Before any planned system shutdown or after any system additions, removals, or  
modifications (including firmware updates, logical drive creations, storage  
partitioning definitions, hardware changes, and so on), save the storage subsystem  
profile as explained in the DS3000 Storage Manager guide for the operating  
system. Save the profile in a location other than the logical drives that are created  
for the DS3200.  
Always see the readme file that is included with the DS3200 Storage Subsystem  
firmware package (whether the firmware is accessed by the Web or a CD) for any  
special requirements or restrictions that apply to that firmware version.  
Note: Be sure to install the DS3000 Storage Manager event monitoring service to  
enable continuous monitoring of the status of the storage subsystem. For  
more information about the importance of this information, see “Monitoring  
status through software.”  
Monitoring status through software  
Use the DS3000 Storage Manager software to monitor the status of the storage  
subsystem. Run the software constantly, and check it frequently.  
Notes:  
1. You can monitor only storage subsystems that are within the management  
domain of the storage-management software.  
2. If you have not installed the DS3000 Storage Manager Event Monitor service as  
part of the storage-management software installation, the DS3000 Storage  
Manager Enterprise Management window must remain open. (If you close the  
window, you will not receive any alert notifications from the managed storage  
subsystems.)  
For more information, see the Enterprise Management online help.  
Important: See the IBM System Storage DS3000 Storage Manager Version 2  
Installation and Support Guide for the applicable operating system for  
instructions for installing the DS3000 Storage Manager Version 2  
software. The Installation and Support Guide is in the Documentation  
folder on the IBM System Storage DS3000 Support CD.  
To download the latest version of the DS3000 Storage Manager  
software, the DS3200 storage subsystem controller firmware and  
NVSRAM, and the latest DS3000 ESM firmware, go to  
http://www.ibm.com/servers/storage/support/disk/.  
The DS3000 Storage Manager software provides the best way to diagnose and  
repair storage-subsystem failures. The software can help you:  
v Determine the nature of the failure  
v Locate the failed component  
v Determine the recovery procedures to repair the failure  
Amber (needs attention) LEDs do not necessarily indicate which component has  
failed or must be replaced or which type of recovery procedure you must perform.  
In some cases (such as when a hard disk drive exceeds its Predictive Failure  
Analysis [PFA] threshold), the amber LED is not lit. Only the DS3000 Storage  
Manager software can detect the failure.  
Chapter 4. Operating the storage subsystem 49  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
For example, the recovery procedure for a PFA flag (impending drive failure) on a  
drive varies depending on the drive status (hot spare, unassigned, RAID level,  
current logical drive status, and so on). Depending on the circumstances, a PFA  
flag on a drive can indicate a high risk of data loss (if the drive is in a RAID 0  
volume) or a minimal risk (if the drive is unassigned). Only the DS3000 Storage  
Manager software can identify the risk level and provide the necessary recovery  
procedures.  
Note: For PFA flags, the system-error LED and hard disk drive status LEDs are not  
lit, so checking the LEDs will not notify you of the failure, even if the risk of  
data loss is high.  
Recovering from a storage-subsystem failure might require you to perform  
procedures other than replacing the component (such as backing up the logical  
drive). The DS3000 Storage Manager software provides these procedures.  
Attention: Not following the software-recovery procedures can result in data loss.  
In addition, always replace a failing component as soon as possible to minimize  
additional failures that might occur, causing loss of data access.  
Firmware updates  
Attention: Save the storage subsystem profile before you perform any controller  
or ESM firmware upgrades. Save the profile and all configuration (.cfg) files to a  
server disk that will remain accessible in the event of a DS3200 storage  
configuration failure. Do not save these files only to a LUN in the storage  
subsystem.  
To ensure the optimal operation of the storage subsystem and its attached storage  
expansion enclosures, the storage expansion enclosure ESM firmware, the DS3200  
controller firmware, the hard disk drive firmware, and the NVSRAM (for controllers  
only) must be up-to-date. Go to http://www.ibm.com/servers/storage/support/disk/ to  
get the latest updates.  
Always see the readme files that are included with the firmware packages for the  
most up-to-date information about firmware prerequisites, firmware update  
instructions, download-sequence information, and host I/O restrictions, if any. Apply  
the necessary updates before you configure the storage subsystem arrays and  
logical drives. Subscribe to My Support for automatic notifications of firmware or  
Storage Manager software updates or any important information about the DS3000  
storage subsystems (see “Product updates” on page 5).

Attention: Failure to observe the limitations, prerequisites, sequences, and  
dependencies in the readme file might result in a loss of data access.  
Unless the readme file contains special requirements for the sequence in which you  
upgrade firmware, perform firmware upgrades in the following sequence:  
1. ESM firmware for the storage expansion enclosures  
2. Controller firmware  
3. Controller NVSRAM  
4. Drive firmware  
Troubleshooting the storage subsystem  
The DS3000 Storage Manager software is the best way to monitor the storage  
subsystem, diagnose a problem, and recover from a hardware failure. Run the  
DS3000 Storage Manager continuously, and frequently check the configuration  
status.  
To check the status of and identify a problem with the storage subsystem, complete  
the following steps. If a problem has occurred, use the DS3000 Storage Manager  
software and the LEDs on the storage subsystem to help locate a failed component.  
1. Open the Subsystem Management window.  
2. Click the Summary tab, and view the status of the storage subsystem.  
3. Does any storage subsystem have a Needs Attention status?  
v Yes: Go to step 4.  
v No: All components are Optimal. Go to step 5.  
4. Click Recovery Guru on the toolbar. Perform the procedure in the Recovery  
Guru to correct the problem. The Recovery Guru might direct you to replace the  
failed component. If so, go to step 5.  
Attention: If the fault requires you to power-off an attached storage expansion  
enclosure, you might have to cycle the power on the DS3200 storage  
subsystem and all remaining storage expansion enclosures that are connected  
to the storage subsystem. Contact your IBM technical-support representative  
before you power-off any attached storage expansion enclosures.  
5. Check the LEDs on the front and the rear of the storage expansion enclosure. A  
green LED indicates a normal status; an amber LED indicates a hardware fault.  
6. Is an amber LED lit?  
v Yes: Locate and troubleshoot the failed components. See “Checking the  
LEDs” on page 52.  
v No: You are finished with this procedure. If you are still experiencing a  
problem with the storage subsystem, create, save, and print a storage  
subsystem profile, and contact your IBM technical-support representative for  
assistance. When the recovery procedure is completed, select Recheck in  
the Recovery Guru to run the Recovery Guru again to make sure that the  
problem is corrected.

Checking the LEDs  
The LEDs indicate the status of the storage subsystem and components. Green  
LEDs indicate a normal operating status; amber LEDs (needs attention) indicate a  
possible failure; a blue LED on a component indicates that it is safe to remove that  
component.  
The DS3200 also has a blue system locator LED that is lit when the menu function  
is selected in the Subsystem Management window, causing the Locate command to  
be sent to the DS3200.  
Check all the LEDs on the front and rear of the storage subsystem when you turn  
on the power. During power-on, the LEDs flash intermittently as the storage  
subsystem and components complete the power-on process. In addition to checking  
for faults, you can use the LEDs on the front of the storage subsystem to determine  
whether the drives are responding to I/O transmissions from the host.

Turning off the storage subsystem  
The DS3200 is designed to run continuously. After you turn it on, do not turn it off.  
Turn off the power only in the following situations:  
v Instructions in a hardware or software procedure require that you turn off the  
power.  
v An IBM technical-support representative instructs you to turn off the power.  
v A power outage or emergency situation occurs, see “Restoring power after an  
unexpected shutdown” on page 57.  
Attention: Except in an emergency, never turn off the power if any amber (needs  
attention) LEDs are lit. Correct the fault before you turn off the power. Use the  
DS3000 Storage Manager software and the amber LEDs to check the overall status  
of the DS3200. All LEDs should be green on the front of the storage subsystem. If  
they are not, use the DS3000 Storage Manager software to diagnose the problem  
so that the DS3200 will power-on correctly later.

Power-off overview  
Review the following information before you continue with the power-off  
procedure:  
Turn off the power to each device according to the following shutdown  
sequence:  
1. Turn off power to the host before the storage subsystem. If the host must  
stay powered-on to support a network, see the operating-system  
documentation for information about disconnecting the storage subsystem  
logical drives from the host before the storage subsystem is powered-off.  
2. Turn off power to the storage subsystem before you turn off power to the  
storage expansion enclosures. Turn off both power-supply switches on the  
rear of the storage subsystem.  
3. Turn off power to other supporting devices (for example, management  
stations).  
Note: You do not have to perform this step if you are servicing only the  
storage subsystem.  
To turn off power to one or more storage subsystems for a planned shutdown,  
complete the steps in the following procedure. To turn off power for an unplanned  
shutdown, see “Restoring power after an unexpected shutdown” on page 57.  
Figure 33 on page 47 shows the locations of the power switches on a storage  
subsystem.  
Before you proceed, use the Storage Manager software to determine the status of  
the system components and special instructions. The operating-system software  
might require you to perform other procedures before you turn off the power.  
1. Stop all I/O activity to each storage subsystem.  
2. Determine the status of all storage subsystems and components in the  
configuration by completing the following steps:  
a. Check all LEDs on each component in the storage expansion enclosures.  
Make sure that all the LEDs show normal status.  
b. Check all LEDs on each component in the storage subsystem. Make sure  
that all the LEDs show normal status.  
c. Review the status of the configuration in the Subsystem Management  
window by clicking the Summary tab.  
The status is either Optimal or Needs Attention.  
3. Do the LEDs indicate normal operation, and is the status Optimal on all  
configuration components?  
v Yes: Go to step 5 on page 57.  
v No: Go to step 4.  
4. To diagnose and correct the fault, complete the following steps:  
a. Run the Recovery Guru by clicking Recovery Guru in the toolbar in the  
Subsystem Management window.  
b. Complete the recovery procedure.  
If the Recovery Guru directs you to replace a failed component, use the  
individual LEDs to locate the failed component.

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
c. When the recovery procedure is completed, click Recheck in the Recovery  
Guru. This action runs the Recovery Guru again to make sure that the  
problem is corrected.  
d. If the problem has not been corrected, contact your IBM technical-support  
representative. Do not turn off power until all problems are corrected.  
5. Check the cache active LED, and make sure that it is off.  
If the cache active LED is lit, the cache contains data. Wait for the data to clear  
from cache memory before you turn off the power.  
6. Check the LEDs on the storage expansion enclosures to make sure that all  
drive activity LEDs are off.  
If one or more LEDs are flashing, data is being written to or from the drives.  
Wait for all activity LEDs to stop flashing.  
7. Turn off the ac power switch on the rear of each controller in the storage  
subsystem.  
Note: Until the power switch on each controller is turned off, power remains  
turned on for both controllers.  
8. Turn off both power switches on the rear of each storage expansion enclosure  
in the configuration.  
9. After you perform the necessary maintenance procedures, turn on the power,  
using the procedure in “Turning on the storage subsystem” on page 46.  
Performing an emergency shutdown  
Attention: Emergency situations might include fire, flood, extreme weather  
conditions, or other hazardous circumstances. If a power outage or emergency  
situation occurs, always turn off all power switches on all computing equipment.  
This helps to safeguard your equipment from potential damage due to electrical  
surges when power is restored. If the storage subsystem loses power unexpectedly,  
it might be due to a hardware failure in the power system or in the midplane.  
To shut down the system during an emergency, complete the following steps:  
1. If you have time, stop all I/O activity to the storage subsystem by shutting down  
the host or disconnecting the storage subsystem logical drives through the host.  
2. Check the LEDs. Make note of any amber LEDs that are lit so that you can  
correct the problem when you turn on the power again.  
3. Turn off all power-supply switches, starting with the DS3200 storage subsystem  
first and followed by the storage expansion enclosures. Then, disconnect the  
power cables from the storage subsystem.  
Restoring power after an unexpected shutdown  
To restore power to the storage subsystem in a configuration after an unplanned  
shutdown, complete the following steps.  
DANGER  
Never turn on any equipment when there is evidence of fire, water, or  
structural damage.  
1. After the emergency situation is over or power is restored, visually check the  
storage subsystem for damage. Is there evidence of damage to any of the  
storage subsystem components, cables, or equipment that is attached to the  
storage subsystem?  
Chapter 4. Operating the storage subsystem 57  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
v Yes: Do not continue with this procedure. Contact your IBM technical-support  
representative for assistance. Depending on the current service agreements,  
you might have to return the equipment to the factory or local service center  
for repair.  
v No: Go to step 2.  
Attention: To avoid potential data loss, make sure that the storage  
subsystem and storage expansion enclosure power switches are turned off  
before you reset circuit breakers in the rack cabinet. Resetting circuit  
breakers after an emergency situation while the storage subsystem and  
storage expansion enclosure power switches are turned on can cause data  
loss, because the configuration components might not be powered-on in the  
correct sequence. See “Turning on the storage subsystem” on page 46 for  
details about the correct power-on sequence.  
2. After you check the storage subsystem for damage, make sure that the power  
switches are off; then connect the DS3200 power cables, if required.  
3. Check the system documentation of the hardware devices that you want to turn  
on and determine the correct startup sequence.  
Be sure to turn on all of the storage expansion enclosures and make sure that  
no ESM or power-supply fault LEDs are lit before you turn on the DS3200.  
In addition, consider the following items:  
v The storage subsystem supports simultaneous power-on of the system  
components; however, always follow the power-on sequence that is described  
in the “Turning on the storage enclosure" section of the applicable  
Installation, User’s, and Maintenance Guide during any attended power-on  
procedure.  
v A storage subsystem in an optimal state recovers automatically from an  
unexpected shutdown and unattended simultaneous restoration of power to  
system components. After power is restored, contact your IBM  
technical-support representative if any of the following conditions occur:  
– The storage subsystem logical drives and subsystems are not displayed in  
the Storage Manager graphical user interface.  
– The storage subsystem logical drives and subsystems do not come online.  
– The storage subsystem logical drives and subsystems seem to be  
degraded.  
4. Turn on the power to each device, according to the startup sequence.  
5. Turn on both of the power-supply switches on the DS3200. The green LEDs on  
the front and the rear of the DS3200 should remain lit. If other amber LEDs are  
lit, see Chapter 6, “Solving problems,” on page 99.  
Recovering from an overheated power supply  
Each storage subsystem contains two power supplies. Each power supply contains  
a built-in temperature sensor to prevent the power supply from overheating. Under  
normal operating conditions, with an ambient air temperature range of 10°C to 35°C  
(50°F to 95°F), the fans in the power-supply units maintain a suitable operating  
temperature inside the module.  
If the internal temperature reaches 65°C (149°F), the power supply shuts down  
automatically. If both power supplies shut down because of overheating, the storage  
subsystem has no power, and all LEDs are off.  
The following factors can cause the power supplies to overheat:  
58 System Storage DS3200 Storage Subsystem: Installation, User’s, and Maintenance Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
v An unusually high room temperature  
v Fan failures in the power-supply units  
v Defective circuitry in a power supply  
v Blocked air vents  
v Failures in other devices in the configuration or rack cabinet  
If a fan failure causes overheating, the system-error LED and overtemperature  
LEDs on the storage subsystem are lit. The fault LED on the power supply might  
also be lit. “Checking the LEDs” on page 52 shows the location of the LEDs on the  
DS3200.  
If the storage subsystem temperature exceeds 45°C (113°F), the storage  
management software displays a Needs Attention icon in the Subsystem  
Management window. If the air temperature inside the rack cabinet reaches 65°C  
(149°F), the power supplies automatically shut down. If event monitoring is enabled  
and event notification is configured, the software issues two critical-problem  
notifications.  
v If one power supply shuts down, the storage management software displays a  
Needs Attention status in the Subsystem Management window.  
v If both power supplies shut down, the storage subsystem shuts down, and the  
storage management software displays a Not Responding status in the Array  
Management window.  
Attention: To prevent damage to the DS3200 storage subsystem components  
when the power supplies automatically shut down, immediately remove all rack  
cabinet panels to help reduce the rack cabinet air temperature.  
To resume normal operation after a power-supply shutdown, complete the following  
steps:  
1. Did you use the procedure “Troubleshooting the storage subsystem” on page  
51 to identify an overheating problem?  
v Yes: Go to step 2.  
v No: Perform the procedure in “Troubleshooting the storage subsystem” on  
page 51 to make sure that the power supplies have shut down because of  
an overheating problem, and then go to step 2.  
2. Stop I/O activity to the storage subsystem and all attached storage expansion  
enclosures.  
3. Take all or some of the following measures to alleviate the overheating  
problem:  
v Remove all panels from the rack cabinet immediately.  
v Use external fans to cool the area.  
v Shut down the power to the storage expansion enclosure, using the  
procedure that is described in “Performing an emergency shutdown” on  
page 57.  
4. Wait for the air in and around the storage subsystem to cool.  
After the temperature inside the power supplies drops to below 65°C (149°F),  
the storage subsystem is capable of power-on recovery without operator  
intervention. After the air has cooled, the power supplies should turn on  
automatically. If the power supplies restart automatically, the controllers will  
reset and return to normal operation.  
5. Did the power supplies restart automatically?  
v Yes: Go to step 8 on page 60.  
Chapter 4. Operating the storage subsystem 59  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
v No: Go to step 6.  
6. Turn off both power switches on the DS3200 (see Figure 33 on page 47) and  
then power-off all connected storage expansion enclosures. Wait 1 minute and  
then turn on power to all connected storage expansion enclosures.  
While a storage expansion enclosure powers-on, the LEDs on the front and  
the rear of the enclosure flash intermittently. Depending on your configuration,  
the storage expansion enclosure can take between 20 seconds and several  
minutes to power-on.  
7. Turn on both power switches on the rear of the DS3200. See Figure 33 on  
page 47.  
A storage subsystem can take 10 seconds to power-on and up to 15 minutes  
for the battery self-test to be completed. During this time, the LEDs on the  
front and the rear of the DS3200 flash intermittently.  
8. Check the LEDs on the front and rear of the DS3200 storage subsystem and  
each attached storage expansion enclosure (a green LED indicates a normal  
status; an amber LED indicates a hardware fault); then, check the array status  
in the Subsystem Management window.  
a. Open the Subsystem Management window for the storage array.  
b. Click the Summary tab and review the status of the configuration.  
The status is either Optimal or Needs Attention.  
9. Does each module (RAID controller, power supply, ESM) display green status  
LEDs only, and is the status Optimal for each module component?  
v Yes: Go to step 11.  
v No: Go to step 10.  
10. Diagnose and correct the fault.  
a. To run the Recovery Guru, click Recovery Guru in the toolbar in the  
Subsystem Management window.  
b. Complete the recovery procedure.  
If the Recovery Guru directs you to replace a failed component, locate and  
troubleshoot that component. See “Checking the LEDs” on page 52.  
c. When the procedure is completed, select Recheck in the Recovery Guru.  
This runs the Recovery Guru again to make sure that the problem is  
corrected.  
d. If the problem remains, contact your IBM technical-support representative.  
11. Replace the bezel on the storage expansion enclosure, if applicable.  
Cache memory and cache battery  
Each RAID controller in the DS3200 storage subsystem supports either 512 MB or  
1 GB of cache memory to store read and write operations. (Both RAID controllers in  
the DS3200 must have the same amount of cache memory.) The battery in each  
controller can maintain the data in the RAID controller cache for up to 3 days in the  
event that the DS3200 storage subsystem loses power.  
Attention: There are different part numbers for a DS3200 replacement SAS  
controller, depending on whether the optional SAS host port adapter is installed in  
the existing controller. See the storage subsystem profile for information about the  
installed SAS host port adapter, if there is one, and see “Replaceable components”  
on page 105 for the correct part number for the replacement DS3200 controller.  
60 System Storage DS3200 Storage Subsystem: Installation, User’s, and Maintenance Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Cache memory  
Cache memory is memory on the RAID controller that is used for intermediate  
storage of read and write data on the DS3200 RAID controllers. Using cache  
memory can increase system performance. The data for a read operation from the  
host might be in the cache memory from a previous operation (thus eliminating the  
need to access the drive itself), and a write operation is completed when it is written  
to the cache, rather than to the drives.  
The RAID controller has a cache active LED that indicates the current status of the  
cache. The LED is lit if there is data in the cache, and it is off if there is no data in  
the cache.  
If caching is enabled and the cache active LED is not lit during I/O activity, it  
indicates one of the following conditions:  
v The cache memory from either controller A or controller B has failed.  
v The cache sizes in controller A and controller B are not the same.  
v The battery has failed. (In this case, the amber battery fault LED is lit.)  
Note: Always use the DS3000 Storage Manager software to check the cache  
memory settings before you assume that a hardware failure has occurred.  
See “Controller LEDs” on page 53 for the location of the cache active LED on a  
RAID controller.  
Controller cache battery  
The battery in each controller provides backup power to maintain any cached data  
that was not written to disks, in the event of a power loss. The battery in a  
controller can provide power to the data cache in the controller for up to 3 days.  
CAUTION:  
The battery is a lithium ion battery. To avoid possible explosion, do not burn.  
Exchange only with the IBM-approved part. Recycle or discard the battery as  
instructed by local regulations. In the United States, IBM has a process for  
the collection of this battery. For information, call 1-800-426-4333. Have the  
IBM part number for the battery unit available when you call. (C007)  
Replace a battery in the DS3200 when it is identified as failing by the DS3000  
Storage Manager Subsystem Management window, or when the battery fault LED  
on the RAID controller is lit. See “Controller LEDs” on page 53 for the location of  
the battery fault LED.  
If the DS3200 has two RAID controllers, replace only the battery that is indicated as  
failed in the DS3000 Storage Manager Subsystem Management window. You do not  
have to replace the batteries in both controllers if only one battery has failed.  
The controller performs a learn-cycle test every thirteen weeks. During the  
learn-cycle test, the controller cache battery is discharged and then recharged to  
determine the full charge capacity of the battery pack and to extend the life of the  
battery.  
Note: The controller performs a learn-cycle test after a controller cache battery is  
replaced.  
Chapter 4. Operating the storage subsystem 61  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
If the battery fails the learn-cycle test, the battery fault LED is lit, indicating a battery  
fault, and a Defect Battery error message is displayed in the event log.  
In the Storage Manager software, if the battery age timer indicates that the battery  
is 2 years old, but the battery is not reported as failed, do not call your IBM  
technical-support representative to replace the battery. Instead, reset the battery  
age by using the procedure that is described in the Storage Manager software  
online help.  
Attention: Write caching is suspended while a battery is either charging or  
performing learn-cycle testing.  
Controller battery age timer  
The controller maintains a battery age timer for the controller cache battery. The  
timer is set to indicate when the battery is 2 years old. Thirty days before the  
battery expiration date, a warning message is displayed in the DS3000 Storage  
Manager software.  
After you replace a controller cache battery, reset the battery age timer. For  
information about resetting the batter age timer, see the Storage Manager software  
online help.  
If the controller is running firmware version 07.35.41.00 or later, the controller uses  
a smart battery learn-cycle test. The smart battery learn-cycle determines when the  
cache battery is defective and needs to be replaced. The battery learn-cycle test  
removes the need to rely on the battery age timer to determine the expiration date  
of the cache battery. If the cache battery expiration message is still displayed after  
you replace a controller cache battery, reset the battery age timer.

Chapter 5. Replacing components  
This chapter contains information about replacing the storage subsystem  
components. It also contains information about installing an optional SAS host port  
adapter in a RAID controller.  
Attention: Always replace a failed component as soon as possible. The Recovery  
Guru in the DS3000 Storage Manager software identifies failed components.  
Service action allowed LED  
Each controller and power supply has a blue service action allowed LED. The  
purpose of the service action allowed LED is to help ensure that a component is not  
removed before it is safe to do so. Do not remove any DS3200 component unless  
the component service action allowed LED is lit.  
Attention  
If you remove a controller or power supply when the service action allowed  
LED is not lit, a loss of data availability can result. If an amber LED is lit and  
the associated service action allowed LED is not lit, you must perform  
additional diagnostics before you can remove the indicated component. Use  
the Recovery Guru instructions in the DS3000 Storage Manager Subsystem  
Management window or see the applicable component replacement  
instructions in this chapter for the additional diagnostics that are required in  
this case.  
The service action allowed LED automatically turns on or off as conditions change.  
Wait at least 2 minutes after you replace a component for the storage subsystem to  
recognize the new component and update the LED status. In most cases, when a  
single component fails, the service action allowed LED stays lit when the amber  
LED is lit for the component.  
Removing a controller  
Attention: Before you remove a controller in a single-controller DS3200, shut  
down the DS3200 to avoid data loss (see “Turning off the storage subsystem” on  
page 55).  
To remove a controller from the storage subsystem, complete the following steps:  
1. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
Attention: Never remove a controller unless the service action allowed LED is  
lit. Doing so can result in a loss of data.  
2. If the controller has failed, do not continue with this procedure. Instead, go to  
“Replacing a controller” on page 66.  
Attention: Handle and install SAS cables correctly to avoid degraded  
performance or loss of communication with devices. When you work with SAS  
cables, do not pinch them, step on them, or locate them in aisles or walkways.  
Do not overtighten the cable straps or bend the cables to a radius smaller than  
38 mm (1.5 in.).

just enough to release the handle; then, rotate the handle upward.  
b. Slowly pull the handle away from the chassis to remove the controller from  
the bay, as shown in Figure 38.  
c. Place the controller on a level surface.  
Attention: After you remove a controller, wait 70 seconds before you reseat or  
replace the controller. Failure to do so might cause unpredictable results.  
Installing a controller  
Use this procedure to install a new controller as the second controller, controller B  
(controller A is installed in the left controller bay; controller B is installed in the right  
controller bay).  
Attention: Make sure that the two controllers have the same cache memory  
capacity and options (the optional SAS host port adapter is either installed in both  
controllers or is not installed in both controllers). An incompatible controller will be  
placed in a lockout state by the other controller in the DS3200.  
To install a controller in the storage subsystem, complete the following steps:  
1. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
2. Make sure that the second controller has the same DIMM size, and options  
(such as a host port adapter) as controller A.  
3. Install new dual-controller NVSRAM on controller A. See “Downloading  
controller or NVSRAM” in the System Storage DS3000 Storage Manager  
Installation and Support Guide for information about how to download the  
NVSRAM software.  
Note: Obtain the latest dual-controller NVSRAM software from  
http://www.ibm.com/servers/storage/support/disk/.

4. Start the command-line interface; then, enter the following command to change  
controller A from simplex (single-controller) mode to duplex (dual-controller)  
mode:  
Smcli ctlr_A_IP_address -c "set storageSubsystem redundancyMode=duplex;"  
5. Shut down the storage subsystem, and then start it again (see “Turning on the  
storage subsystem” on page 46). If controller A was successfully converted to  
duplex mode, the subsystem reports an alternate controller missing error  
message. If the error message is not reported, reinstall the new dual-controller  
NVSRAM on controller A and repeat steps 4 through 5.  
6. Unpack the new controller. Save all packing materials in case you have to  
return a controller.  
7. If controller A contains an optional SAS host port adapter, install an identical  
optional SAS host port adapter in the new controller. See “Installing an optional  
SAS host port adapter” on page 69 for instructions.  
8. Remove the controller filler panel from the controller B bay:  
a. On the left side of the filler panel, press the orange release tab to the right  
just enough to release the handle; then, rotate the handle upward.

12. Make sure that all storage expansion enclosure connections with each other  
have been completed (see the dual-controller topologies in “DS3200 storage  
subsystem drive cabling topologies” on page 28); then, connect the SAS drive  
expansion cable from the right ESM in the last storage expansion enclosure in  
the chain to the drive expansion port on controller B of the DS3200.  
13. Wait up to 5 to 10 minutes for the DS3000 Storage Manager software to report  
the drives and the redundant drive path.  
14. Verify the state of the LEDs on the newly inserted controller. See “Controller  
LEDs” on page 53. You can also use the DS3000 Storage Manager  
Subsystem Management window to identify any new faults. Do any storage  
subsystems have a fault (Needs Attention) status?  
v Yes: Click Recovery Guru in the Subsystem Management window toolbar,  
and complete the recovery procedure. If the problem remains, contact your  
IBM technical-support representative.  
v No: Go to step 15.  
15. Use the DS3000 Storage Manager software to print a new storage subsystem  
profile.  
Replacing a controller  
Use these instructions to replace a controller.  
Attention: Make sure that both power-supply units are connected and  
powered-on and no amber LEDs are lit. Make sure that the power LEDs on both  
power-supply units are lit. If the status of either of the power-supply units is not  
Optimal, replace that power supply before you proceed with the controller  
replacement procedure.  
To replace a controller in a DS3200, complete the following steps.  
Attention:  
v If you are replacing a failed controller with a replacement controller from IBM  
Service, you will transfer the controller battery to the replacement controller. The  
replacement controller contains a 512 MB DIMM; if the capacity of the DIMM in  
the failed controller is larger than 512 MB, you will also transfer that DIMM to the  
replacement controller. Transfer the DIMM and battery exactly as described in  
this procedure; failure to remove and insert these items in the correct sequence  
can damage the DIMM.  
v In a single-controller DS3200, shut down the DS3200 before you remove the  
controller.  
1. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
2. In a single-controller storage subsystem, shut down the storage subsystem  
(see “Turning off the storage subsystem” on page 55 for the correct sequence  
of steps); then, continue with step 4.  
3. Use the DS3000 Storage Manager software to print a storage subsystem  
profile. Move logical drive ownership to the other controller. If the controller that  
you are replacing has failed but is still operating, move the failed controller to  
the Offline state.  
Attention: Never remove a controller unless the service action allowed LED  
is lit. Doing so can result in a loss of data.  
4. Locate the failed controller by checking the amber LEDs on the controllers in  
the storage subsystem.

5. Is the service action allowed LED lit?  
v Yes: Go to step 6.  
v No: Another component might require attention before you can remove the  
controller. Use the Recovery Guru in the DS3000 Subsystem Management  
window to identify and correct any additional failures. If there are none,  
proceed with step 6 to replace the controller.  
Attention: Static electricity can damage the storage subsystem and other  
electronic devices. To avoid damage, keep static-sensitive devices in their  
static-protective packages until you are ready to install them.  
6. Unpack the new controller. Save all packing materials in case you have to  
return the new controller.  
7. Determine whether the replacement controller will be controller A or controller  
B (controller A is installed in the left controller bay; controller B is installed in  
the right controller bay), and then apply the controller labels for host ports and  
drive expansion ports to the replacement controller. The controller labels and  
instructions are included with the replacement controller. Make sure that the  
labels are aligned correctly and do not cover any connectors or LEDs.  
Attention: Handle and install SAS cables correctly to avoid degraded  
performance or loss of communication with devices. When you work with SAS  
cables, do not pinch them, step on them, or locate them in aisles or walkways.  
Do not overtighten the cable straps or bend the cables to a radius smaller than  
38 mm (1.5 in.).  
8. Disconnect all attached interface cables from the failed controller. Be sure to  
label each cable so that you can reconnect it correctly to the new controller.  
9. If the controller has failed in a single-controller storage subsystem, turn off the  
power immediately (see “Performing an emergency shutdown” on page 57 for  
instructions.)

Installing an optional SAS host port adapter  
Note: The DS3200 SAS 2-Port Daughter Card option is referred to in this  
document as host port adapter.  
This section explains how to install an optional SAS host port adapter into a  
controller.  
Attention: If you install a host port adapter in a controller, you must make sure  
that an identical host port adapter is installed in the other controller on the DS3200,  
for correct operation of the controllers.  
The SAS host port adapter adds two additional host ports to the controller.  
To install a SAS host port adapter, complete the following steps.  
Attention: To prevent data loss, you must shut down the storage subsystem  
before you remove the controller from the chassis. For the correct shutdown  
sequence, see “Turning off the storage subsystem” on page 55.  
1. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.

Working with hot-swap hard disk drives  
This section explains how you can increase the storage subsystem capacity by  
adding more hard disk drives or by replacing existing drives with ones that have a  
larger capacity.  
Before you begin, complete the following tasks:  
v Read the safety information that begins on page xi and “Handling static-sensitive  
devices” on page 19.  
v Make sure that the current system configuration is working correctly.  
v Back up all important data before you make changes to data storage devices.  
Before you install or remove drives, review the following information:  
v Filler panels: A storage subsystem without a full set of drives (12) contains filler  
panels in the unused drive bays. Before you install new drives, you must remove  
these filler panels. Save the filler panels for future use. For proper cooling and  
EMC protection, each of the 12 bays must always contain either a filler panel or  
a hot-swap hard disk drive.  
v Drives:  
– The DS3200 supports 3 Gbps SAS or SATA hard disk drives.  
– For optimum performance, never insert a drive into the storage subsystem  
without first confirming the drive firmware level. Contact your IBM  
technical-support representative for information about supported drive  
firmware levels.  
– Use of unsupported drives can cause the storage subsystem to fail.  
– After you remove a drive, wait 70 seconds before you replace or reseat the  
drive to allow the drive to spin down. Failure to do so might cause  
unpredictable results.

Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Attention  
Before you power-on the storage subsystem, it must contain at least four  
drives. If at least four drives are not installed in each attached storage  
expansion enclosure and in the DS3200 storage subsystem, when you  
power-on the DS3200 and its attached storage expansion enclosures, your  
standard storage partition key might be lost and you must regenerate it,  
using instructions at http://www.ibm.com/storage/fasttkeys/.  
In addition, the resulting insufficient load to the enclosure power supplies  
might cause them to intermittently appear to have failed, falsely indicating  
that the power supplies are bad. All drives in the DS3200 storage  
subsystem and the connected storage expansion enclosure or enclosures  
must contain no prior configuration data.  
v Drive labels: A label is provided on the front of each hard disk drive. Use this  
label to record the location information for each drive before you remove it. Be  
sure to keep a record of the drives and their corresponding bays. Also, record the  
location information in Table 9 on page 110. If you install a drive in the wrong  
bay, you might lose data.  
v Drive LEDs: Each drive tray has two associated LEDs, a green activity LED and  
an amber status LED. These LEDs indicate the status for that drive.  
Hard disk drive activity LED  
Hard disk drive status LED  
System Storage  
Figure 45. Hard disk drive LEDs  
Activity LED (green)  
When this LED flashes, it indicates that there is activity to the drive.  
Status LED (amber)  
When this LED flashes, it indicates that the drive has been identified by  
the software. When this LED is lit and not flashing, it indicates that the  
drive has failed.  
v Hot-swap hardware: The DS3200 contains hardware that enables you to  
replace a failed hard disk drive without turning off the storage subsystem. You  
can continue to operate the DS3200 while a hard disk drive is being removed or  
installed. These drives are known as hot-swap hard disk drives.

Removing a hard disk drive  
To remove a hot-swap hard disk drive, complete the following steps.  
Note: The hard disk drive comes installed in a drive tray. Do not attempt to detach  
the drive from the tray.  
1. Use Table 9 on page 110 to record the location and identify the hard disk drives.  
Record this information so that you can replace the hard disk drives in the same  
bays from which you removed them.  
2. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
Attention: Never remove a hard disk drive when its green activity LED is  
flashing. Remove a drive only when its amber status LED is lit (not flashing),  
when the drive is inactive (activity LED is off), or when the DS3200 is turned off.  
3. Remove the hard disk drive.

Installing a hard disk drive  
Except during the DS3200 storage subsystem initial power-on, you can add hard  
disk drives while the storage subsystem is turned on and running. To install  
hot-swap hard disk drives in the storage subsystem, complete the following steps.  
Attention: After you remove a drive, wait 70 seconds to allow the drive to spin  
down before you replace or reseat the drive. Failure to do so might cause  
unpredictable results.  
Note: The hard disk drive comes with a tray already attached. Do not attempt to  
detach the drive from the tray.

Replacing a hot-swap hard disk drive  
Drive problems include any malfunctions that delay, interrupt, or prevent successful  
I/O activity between the hosts and the hard disk drives in the storage subsystem.  
Chapter 5. Replacing components 75

This includes transmission problems between the host controllers and the drives.  
This section explains how to replace a failed hard disk drive.  
Note: If you want to remove a hard disk drive that is not in a failed or bypass state,  
always use the Storage Manager software either to place the drive in a failed  
state or to place the array that is associated with the drive (or drives) in an  
offline state before you remove the drive from the storage subsystem.  
Attention: Failure to replace a hard disk drive in its correct bay might result in  
loss of data. If you are replacing a hard disk drive that is part of a configured array  
and logical drive, be sure to install the replacement hard disk drive in the correct  
bay. See the hardware and software documentation that comes with the DS3200 to  
determine whether there are restrictions regarding hard disk drive configurations.  
To replace a hot-swap hard disk drive, complete the following steps:  
1. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
2. Use the DS3000 Storage Manager software to print a new storage system  
profile.  
3. Determine the location of the drive that you want to remove.  
Attention: Never hot-swap a drive when its associated green activity LED is  
flashing. Hot-swap a drive only when its associated amber status LED is lit and  
not flashing.  
4. Remove the drive:  
a. Press the latch on the right end of the tray handle to release it.  
b. Pull the tray handle out into the open position.  
c. Pull the drive approximately 12 mm (0.5 in.) out of the bay and wait 70  
seconds to allow the drive to spin down and the storage subsystem  
controller to recognize that a drive is removed from the configuration.  
Make sure that there is identification (such as a label) on the drive, and then  
slide it completely out of the storage subsystem.  
Attention: After you remove a drive, wait 70 seconds to allow the drive to  
spin down before you replace or reseat the drive. Failure to do so might cause  
unpredictable results.  
5. Unpack the new drive. Save all packing material in case you have to return the  
drive.  
Note: Use Table 9 on page 110 to make sure that you replace the hard disk  
drive into the correct bay.  
6. Install the new drive:  
a. Press the latch on the right end of the tray handle to release it.  
b. Pull out the tray handle to the open position.  
c. Gently slide the drive all the way into the empty bay until the drive stops.  
d. Push the tray handle into the closed (latched) position.  
e. Wait 30 seconds for the system discovery process to be completed.  
7. Check the drive LEDs:  
v When a drive is ready for use, the green activity LED is lit and the amber  
status LED is off.  
v If the amber status LED is lit and is not flashing, remove the drive from the  
unit and wait 70 seconds; then, install the drive again.

Download from Www.Somanuals.com. All Manuals Search And Download.  
8. Make sure that the drive is shown in the DS3000 Storage Manager Subsystem  
Management window.  
Note: If you are replacing more than one hard disk drive, replace only one drive at  
a time.  
Replacing multiple drives  
This section provides guidelines for upgrading the drives in the storage subsystem.  
Read the software documentation and this entire section to determine whether you  
should use this procedure, use a modified version of this procedure, or use a  
different procedure that is provided by the operating system.  
Notes:  
1. Instructions that are provided with the software supersede any instructions and  
information in this document.  
2. Use Table 9 on page 110 to make sure that you replace the hard disk drives into  
the correct bays.  
Attention: After you remove a drive, wait 70 seconds to allow the drive to spin  
down before you replace or reseat the drive. Failure to do so might cause  
unpredictable results.  
There are two methods for upgrading drives:  
v Replacing all the drives at the same time  
This method requires that you back up the data on the affected drives and then  
turn off the DS3200 storage subsystem.  
Attention: Turn off the DS3200 storage subsystem before you turn off the  
attached storage expansion enclosures.  
After you replace all the drives, you must reconfigure the new drives and restore  
data from backup. See the procedure in “Replacing all drives at the same time”  
on page 78.  
This is the safest way to exchange drives without losing data. However, this  
method might take a long time to complete because of the backup,  
reconfiguration, and restoration processes. In addition, other users are not able  
to use the storage subsystem (or any storage expansion enclosures attached to  
the storage subsystem) until you finish the procedure. You must use this method  
on RAID 0 logical drives.  
v Replacing the drives one at a time  
In this method, you manually fail each drive, replace it, and wait for the system to  
restore data to the new drive before you install the next drive. After you install the  
new drives, you can configure them to make the additional drive space available.  
See the procedure in “Replacing the drives one at a time” on page 80.  
Using this method, you can replace the drives while the storage expansion  
enclosures and the DS3200 are running, eliminating the downtime that is  
required if you replace all the drives at once. However, this method is more risky  
because you can lose data if the drive restoration or storage subsystem  
reconfiguration process fails. In addition, the reconstruction process might take a  
long time. This method works only on redundant logical drives (RAID 1, 3, or 5).  
You cannot use this method with any drives that contains RAID 0 logical drives.  
Consider backing up your data if you use this method. This safeguards your data  
if the restoration and reconfiguration process fails or the new drive malfunctions.  
The method that you use depends on the following considerations:  
Chapter 5. Replacing components 77  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
v Which method most closely matches the recommended drive upgrade procedure  
that is provided in the operating-system or storage-management software  
documentation.  
v Which RAID level is used on the affected drives (RAID 0 requires you to replace  
all the drives at the same time).  
v How much downtime is acceptable as you swap the drives.  
v The number of drives in an array. Replacing drives one at a time is better suited  
to arrays that consist of three to five drives. If you have more than 10 drives,  
consider replacing all drives at the same time.  
v How much risk of losing data is acceptable. Because the array is in a degraded  
state during the RAID array reconstruction and copyback process as result of  
replacing a drive in the array, any new drive failure will cause the array to fail  
(causing a loss of data availability and even a loss of data). The duration of the  
reconstruction and copyback process can be quite long, depending on the size of  
the RAID array.  
v How extensively the data will be changed while the array is in a degraded state  
during the RAID array reconstruction and copyback process as a result of  
replacing a drive in the array. The more extensive the data changes are, the  
more work that will have to be performed to restore the data in the event that the  
array fails because an additional drive fails while the array is in a degraded state.  
Replacing all drives at the same time  
Use this procedure to replace all drives at the same time. You must use this method  
if you are upgrading drives that contain RAID 0 logical drives. All the data that is  
currently on the drives is lost when you replace the drives; therefore, you must back  
up all data that is currently on the drives. This procedure also requires you to turn  
off the storage expansion enclosures and the DS3200, which makes the storage  
subsystem (and any attached storage expansion enclosures) inaccessible to other  
users.  
Attention: After you remove a drive, wait 70 seconds to allow the drive to spin  
down before you replace or reseat the drive. Failure to do so might cause  
unpredictable results.  
To replace all the drives at the same time, complete the following steps:  
1. Read the following information:  
v The information in “Replacing multiple drives” on page 77, particularly the  
paragraphs that explain the differences between the two possible upgrade  
procedures  
v The information in the software documentation about drive upgrades and  
installation  
v The documentation that comes with the new drives  
Read all precautionary notes, kit instructions, and other information. Kit  
instructions often contain the most current information about the drives and  
their installation, plus upgrade or servicing procedures. Compare the kit  
instructions with this procedure to determine whether you must modify this  
procedure.  
2. Use the DS3000 Storage Manager software to check the status of the  
DS3200. Correct any problems that are reported.  
3. Perform a complete backup of the drives that you are replacing.  
You need the backup to restore data on the drives later in this procedure.

Attention: When you handle static-sensitive devices, take precautions to  
avoid damage from static electricity. For details about handling static-sensitive  
devices, see “Handling static-sensitive devices” on page 19.  
4. Unpack the new drives.  
Set the drives on a dry, level surface away from magnetic fields. Save the  
packing material and documentation in case you have to return the drives.  
5. Complete the following steps:  
a. Stop all I/O activity to the storage subsystem and attached storage  
expansion enclosures.  
b. Make sure that all of the green drive activity LEDs on the front of the  
storage subsystem (and on all attached storage expansion enclosures) are  
not flashing.  
c. Make sure that the green cache active LEDs are off. See “Controller LEDs”  
on page 53 for the location of the cache active LEDs.  
d. If applicable, use the operating-system software to disconnect the storage  
subsystem logical drives from the host before you power-off the storage  
subsystem.  
Attention: To turn off all power to the storage subsystem, you must turn off  
both power-supply switches and disconnect both power cords. Use the  
procedure in step 6 for the correct shutdown sequence.  
6. Turn off the power to each device according to the following shutdown  
sequence:  
a. Turn off power to the host before you turn off power to the storage  
subsystem. If the host must stay powered-on to support a network, see the  
operating-system documentation for information about disconnecting the  
storage subsystem logical drives from the host before the storage  
subsystem is powered-off.  
b. Turn off power to the storage subsystem before you turn off power to the  
storage expansion enclosures. Turn off both power-supply switches on the  
rear of the storage subsystem.  
c. Turn off power to other supporting devices (for example, management  
stations or Ethernet switches).  
7. Use the procedures in “Replacing a hot-swap hard disk drive” on page 75 to  
remove the drives that you want to replace. Use the procedures in “Installing a  
hard disk drive” on page 75 to install the new drives in the storage subsystem.  
8. After you install all the new drives, check the system documentation for the  
hardware devices that you intend to power-on, and then determine the correct  
startup sequence. Use the following power-on sequence, where applicable:  
a. Turn on the power to the supporting devices (for example, Ethernet  
switches and management stations) before you turn off power to the  
storage subsystem.  
b. Turn on the storage expansion enclosures before the storage subsystem.  
The controllers might not recognize the correct configuration if the drives  
are powered-on after the storage subsystem. For instructions for  
powering-on the storage subsystem, see the storage subsystem  
documentation.  
c. Turn on the power to the storage subsystem; then, restart or turn on the  
power to the host.  
9. Turn on the power to each device, according to the power-on sequence in step  
8. To turn on power to the storage subsystem and the storage expansion

enclosures, turn on the power-supply switches on the rear of the storage  
subsystem. You must turn on both power-supply switches to take advantage of  
the redundant power supplies.  
10. Check the green drive activity LEDs and the amber drive fault LEDs above the  
new drives.  
Make sure that the drive activity LEDs are lit and the drive fault LEDs are off.  
Note: The drive fault LEDs might flash intermittently while the drives spin up.  
v If a drive activity LED is off, the drive might not be installed correctly.  
Remove the drive, wait 70 seconds, and then reinstall it.  
v If the drive fault LED stays lit or the drive activity LED stays off, the new  
drive might be faulty. See the DS3000 Storage Manager software for  
problem determination.  
11. Use the DS3000 Storage Manager software to configure the new drives. See  
the DS3000 Storage Manager software online help for detailed instructions.  
12. Restore the data from backup to all the drives.  
Replacing the drives one at a time  
Use this procedure to replace all the drives one at a time. You cannot use this  
procedure on RAID 0 logical drives (use the procedure in “Replacing all drives at  
the same time” on page 78).  
Note: If hot spares are assigned in the storage subsystem, you might want to  
unassign the hot spares while you perform this procedure. If you do not,  
reconstruction might start on the hot spare before you insert the new drive.  
The data on the new drive is still rebuilt, but the process takes longer for  
each drive. Remember to reassign the hot spares when you are finished with  
this procedure.  
Attention: After you remove a drive, wait 70 seconds to allow the drive to spin  
down before you replace or reseat the drive. Failure to do so might cause  
unpredictable results.  
To replace the drives one at a time, complete the following steps:  
1. Read the following information:  
v “Replacing multiple drives” on page 77, particularly the paragraphs that  
explain the differences between the two possible upgrade procedures  
v Your software documentation about drive upgrades and installation  
v The documentation that comes with the new drives  
Read all precautionary notes, kit instructions, and other information. Kit  
instructions often contain the most current information about the drives and  
their installation, plus upgrade or servicing procedures. Compare the kit  
instructions with this procedure to determine whether you must modify this  
procedure.  
2. Use the DS3000 Storage Manager software to check the status of the unit.  
Correct any problems that are reported.  
3. Back up the data in the arrays and logical drives that are configured, using the  
drives that you are replacing.  
Attention: When you handle static-sensitive devices, take precautions to  
avoid damage from static electricity. For details about handling static-sensitive  
devices, see “Handling static-sensitive devices” on page 19.  
4. Unpack the new drives.  
80 System Storage DS3200 Storage Subsystem: Installation, User’s, and Maintenance Guide  
Download from Www.Somanuals.com. All Manuals Search And Download.  
 
Set the drives on a dry, level surface away from magnetic fields. Save the  
packing material and documentation in case you have to return the drives.  
5. Use the DS3000 Storage Manager software to make sure that the array that  
was defined using these drives is in Optimal (not Degraded) state before you  
manually fail the first drive that you want to replace. If the array is in a  
Degraded state, use the recovery procedures to bring the array into the  
optimal state.  
Make sure that:  
v You fail only one drive  
v The software status display shows a Failed status for the applicable drive  
v The amber drive fault LED (on the front bezel below the drive) is lit  
Attention: Removing the wrong drive can cause data loss. Make sure that  
you remove only the failed drive. A lit drive fault LED indicates the failed drive.  
If you remove an active drive accidentally, wait at least 70 seconds and then  
reinstall it. Because you have failed two drives in a RAID array, the array might  
be marked as failed by the controller. This array will not be available to the  
host for I/O. See the DS3000 Storage Manager software for further recovery  
instructions. Do not attempt to replace any drives until the array is brought  
back to Optimal state.  
6. Use the procedures in “Replacing a hot-swap hard disk drive” on page 75 to  
remove the failed drive. Use the procedures in “Installing a hard disk drive” on  
page 75 to install the new drives in the storage subsystem.  
The new drive automatically reconstructs the data after you install it in the  
drive bay.  
During data reconstruction, the amber drive fault LED might be lit for a few  
minutes and then turn off when the green drive activity LED begins flashing. A  
flashing drive activity LED indicates that data reconstruction is in progress.  
Note: If the storage subsystem has active hot spares, data might not start  
copying to the new drive until the data is reconstructed on the hot  
spare. This increases the time that is required to complete the  
procedure.  
7. Check the green drive activity LED and the amber drive fault LED on each of  
the new drives.  
Make sure that the drive activity LEDs are lit and the drive fault LEDs are off.  
Note: The drive fault LEDs might flash intermittently while the drives spin up.  
v If the drive activity LED is off, the drive might not be installed correctly.  
Remove the drive, wait 70 seconds, and then reinstall it.  
v If the drive fault LED stays lit or the drive activity LED stays off, the new  
drive might be faulty or might be an uncertified drive. Use the DS3000  
Storage Manager software for problem determination. In the case of an  
uncertified drive, make sure that the drive options or drive FRU part number  
is correct for the storage subsystem.  
8. Use the DS3000 Storage Manager software to monitor the status of the new  
drive and the progress of the data reconstruction. Wait for data reconstruction  
to finish (the drive activity LED stops flashing).  
Note: The drive activity LED continues to flash after reconstruction is finished  
if there is I/O activity to that drive. In that case, use the host software to  
determine whether the data reconstruction is finished.

The power-supply unit is a component that includes a 515-watt power supply and  
two fans. The power-supply units provide power and cooling for the DS3200. The  
power-supply units circulate air from the front to the rear of the storage subsystem.  
The power-supply units are customer replaceable units (CRUs) and do not require  
preventive maintenance. Use only the supported power-supply units for the specific  
storage subsystem.  
Each power supply has a built-in sensor that detects the following conditions:  
v Over-voltage  
v Over-current  
v Overheated power supply  
If any of these conditions occurs, one or both power supplies will shut down. If the

so on). For more information, see “Restoring power after an unexpected shutdown”  
on page 57.  
If both power supplies fail or if the power supplies cannot maintain an internal  
temperature below 70°C (158°F), the power supplies in the storage subsystem will  
automatically shut down (an overtemperature condition). If this occurs, you must  
cool the storage subsystem and restart it. See “Restoring power after an  
unexpected shutdown” on page 57.  
Attention: The fans in the power-supply units draw in fresh air and force out hot  
air. The power-supply units are hot-swappable and redundant; however, if the fans  
in one power-supply unit fail, you must replace the entire failed power-supply unit  
within 72 hours to maintain redundancy and optimum cooling. Do not remove the  
failed power-supply unit until you have the replacement power-supply unit. When  
you do remove the failed power-supply unit, be sure to install the second  
power-supply unit within 10 minutes to prevent any overheating due to the  
interruption to the air flow that cools the storage subsystem.  
Do not run the storage subsystem without adequate ventilation and cooling,  
because it might cause damage to the internal components and circuitry.  
To replace a power-supply unit, complete the following steps. Figure 48 on page 86  
illustrates removing and inserting a unit.  
Attention: To prevent damage to the storage subsystem components from  
overheating, replace a failed power-supply unit within 10 minutes of removal. If  
replacing it will take longer than 10 minutes, stop all I/O activity to the storage  
subsystem and turn off the power until you complete the replacement.

Replacing a battery  
Each RAID controller in the DS3200 Storage Subsystem contains a rechargeable  
battery that maintains data in the cache memory for 3 days without power to the  
unit. The cache battery is the only type of battery in the DS3200.  
Use the following procedure if the DS3000 Storage Manager software instructs you  
to replace the battery because the current battery has failed. You can also use the  
DS3000 Storage Manager software to check the status of the battery. Because  
write-caching is disabled when the battery fails, replace the failed battery as soon  
as possible to minimize any impact due to the disabling of the write-caching  
function.  
The DS3200 storage subsystem controller cache battery timer is set to indicate  
when the battery is 2 years old. When the battery reaches 2 years of age, it does  
not mean that the battery has failed; but the battery might not be capable of  
maintaining cached controller data for up to 3 days in the event of a subsystem loss  
of power.  
Attention:  
1. If you are also removing the memory cache DIMM, do not start with this  
procedure; instead, follow the instructions in “Replacing a controller” on page  
66.  
2. When you handle static-sensitive devices, take precautions to avoid damage  
from static electricity. For details about handling static-sensitive devices, see  
“Handling static-sensitive devices” on page 19.  
To replace a battery unit, complete the following steps.  
1. Use the DS3000 Storage Manager software to print a storage subsystem profile.  
2. Read the safety information that begins on page xi and “Best practices  
guidelines” on page 6.  
3. Locate the RAID controller that contains the failed battery unit (see “Controller  
LEDs” on page 53).  
Attention: Before you remove a controller in a single-controller DS3200, shut  
down the DS3200 to avoid data loss (see “Turning off the storage subsystem”  
on page 55).

Important notes  
Processor speed indicates the internal clock speed of the microprocessor; other  
factors also affect application performance.  
CD or DVD drive speed is the variable read rate. Actual speeds vary and are often  
less than the possible maximum.  
When referring to processor storage, real and virtual storage, or channel volume,  
KB stands for 1024 bytes, MB stands for 1 048 576 bytes, and GB stands for  
1 073 741 824 bytes.  
When referring to hard disk drive capacity or communications volume, MB stands  
for 1 000 000 bytes, and GB stands for 1 000 000 000 bytes. Total user-accessible  
capacity can vary depending on operating environments.  
Maximum internal hard disk drive capacities assume the replacement of any  
standard hard disk drives and population of all hard disk drive bays with the largest  
currently supported drives that are available from IBM.  
Maximum memory might require replacement of the standard memory with an  
optional memory module.  
IBM makes no representation or warranties regarding non-IBM products and

user manuals or all program functionality.  
Particulate contamination  
Attention: Airborne particulates (including metal flakes or particles) and reactive  
gases acting alone or in combination with other environmental factors such as  
humidity or temperature might pose a risk to the device that is described in this  
document. Risks that are posed by the presence of excessive particulate levels or  
concentrations of harmful gases include damage that might cause the device to  
malfunction or cease functioning altogether. This specification sets forth limits for  
particulates and gases that are intended to avoid such damage. The limits must not  
be viewed or used as definitive limits, because numerous other factors, such as  
temperature or moisture content of the air, can influence the impact of particulates  
or environmental corrosives and gaseous contaminant transfer. In the absence of  
specific limits that are set forth in this document, you must implement practices that  
maintain particulate and gas levels that are consistent with the protection of human  
health and safety. If IBM determines that the levels of particulates or gases in your  
environment have caused damage to the device, IBM may condition provision of  
repair or replacement of devices or parts on implementation of appropriate remedial  
measures to mitigate such environmental contamination. Implementation of such  
remedial measures is a customer responsibility.  
Table 12. Limits for particulates and gases  
Contaminant  
Limits  
Particulate  
v The room air must be continuously filtered with 40% atmospheric dust  
spot efficiency (MERV 9) according to ASHRAE Standard 52.21.  
v Air that enters a data center must be filtered to 99.97% efficiency or  
greater, using high-efficiency particulate air (HEPA) filters that meet  
MIL-STD-282.
