3ware Disk Manager (3DM 2)
Note: 3DM 2 includes software developed by the OpenSSL Project
for use in the OpenSSL Toolkit (http://www.openssl.org/).
3ware Disk Manager 2 (3DM 2), allows you to view the status of and manage
3ware RAID controllers and associated drives. 3DM runs as a service under
Microsoft Windows, and as a daemon under Linux. When it is running, you
can use your browser to view status and perform administrative tasks locally
or remotely.
3DM 2 can display information about 3ware RAID 7000-, 8000- and 9000-
series RAID controllers. However, some version 2 features are only available
for 9000-series controllers.
Two levels of access are provided: user and administrator. Users have view-
only access—they can check the status of drives and units—while
Administrators can view and make changes, using 3DM to configure RAID
units and designate hot spares, and to perform maintenance tasks on RAID
units.
In this section, information about 3DM is organized into the following topics:

see the remaining sections in this guide.
Browser Requirements for 3DM
3DM runs in most current web browsers. Tested and supported browsers
include:
■ Mozilla 1.2 and above
■ Internet Explorer 5.5 and above
Additional requirements:
■ JavaScript must be enabled
■ Cookies must be enabled
■ For best viewing, use a screen resolution of 1024 X 768 or greater, and set
colors to 16 bit color or greater.
Note: Because 3DM may be viewed in different browsers, the
format and style of the 3DM browser windows illustrated in this
chapter are examples only. (Screenshots were taken in Internet
Explorer.) The actual “look” of the windows will depend on the
browser, 3DM version and operating system in use.
Setting up Mozilla
Details about accessing all ports, including port 888, by adding a list of ports
to /Mozilla/default/all.js
Note: For security reasons, some web browsers do not allow
connections to certain ports including port-1080 and 888. To
override this on a per-port basis, the Mozilla release notes
recommend to add a comma-separated list of ports to default/all.js
(in your Mozilla installation directory). For example, to unblock
port 888, use the following line:
pref(“network.security.ports.banned.override”, “888”)
This file is located at:

Starting 3DM and Logging In
Starting 3DM and Logging In
3DM runs as a service under Windows, and as a daemon under Linux.
It is a good idea to leave 3DM running on the system that contains your 3ware
RAID controller. That way email alerts can be sent by 3DM, and
administrators can manage the controller remotely, if remote administration is
enabled.
You can access the 3DM screens to check status information and manage your
3ware RAID controller by logging in to the 3DM screens in your browser.
Starting 3DM under Linux
3DM should start automatically after installation and upon bootup.
To start 3DM manually

1
Login as root.
Afterwards, type:
For Red Hat Linux:
/etc/rc.d/init.d/3dm start
For SuSE Linux:
/etc/rc.d/3dm start
2
Open your browser and enter the URL for your system.
You can also replace “localhost” with the IP address of the computer that
The 3DM login screen appears.
Starting 3DM under Windows
■ From the Start menu, choose Programs > 3ware > 3DM 2.
Your default browser opens and displays the URL for your local
controller.

3ware Disk Manager (3DM 2)
Note: If you close your browser, 3DM continues to run in the
background on the system.
Viewing 3DM Remotely via a Standard Web Browser
When remote administration is enabled, you can use 3DM to check status and
administer your 3ware RAID controller from a browser on any computer, over
an internet connection.
You do not need to install the 3DM software on the remote computer.
Remote connections can be enabled or disabled from the 3DM Settings page.
■ In the address line of your browser, enter the URL or IP of the system
containing the 3ware RAID controller.
If you don’t know the URL or IP for the system, you can contact your
network administrator or from a Windows command prompt, type
ipconfig. From a Linux command prompt, type ifconfig.
Logging In
When you first view 3DM in a browser, you must log in before you can view
or change any information.
Two levels of access are provided:
■ Users can check the status of the controller, units, and drives attached to
it.
■ Administrators can check status, configure, and maintain the equipment.
(Administrator and User status in 3DM is not related to Administrator/User
settings in the operating system.)
To log in to 3DM
1
On the 3DM logon screen, select whether you are a User or
Administrator.
2
Enter your password and click Login.
If you are logging in for the first time after installing 3DM, the default
password for both User and Administrator is 3ware.
Note: If you forget the passwords, uninstalling and reinstalling
3DM resets the passwords to 3ware.

3ware Disk Manager (3DM 2)
Managing E-mail Event Notification
3DM can notify you when the 3ware RAID controller requires attention, such
as when a disk unit becomes degraded and is no longer fault tolerant.
Event notification can only occur while 3DM is running, so it is
recommended that 3DM be left running on the system that contains the 3ware
RAID controller.
When events occur, notification can be e-mailed to one or more recipients.
You can specify the type of events for which notifications will be sent by
selecting the severity:
■ Information will send e-mails for all alarms
■ Warning will send e-mail for alarms with severity of Warning and Error
only.
■ Error will send e-mail for alarms with severity of Error only.
For more information about events and alarms, see “Viewing Alarms” on

Running Two Versions of 3DM
Although you can view information about 7000- and 8000-series controllers
in 3DM 2, some features of version 2 are only available for the 9000-series,
because they require that the firmware contain associated capabilities. When
this is the case, a message appears in the 3DM page indicating that the feature
is not available for the current controller.
The scheduling feature is one that works differently in 9000-series controllers
and earlier controllers. If you want to set the schedule for background tasks
for a 7000- or 8000-series controller, you must do so by using 3DM version
1.x.
If you have multiple controllers in the same system, and the controllers are
from different series, it is possible to install and run both 3DM 2 and 3DM
version 1.x on the same system.
Note: If two different versions of 3DM are both running, they have
to be listening on different ports.
In addition, alarms cannot be captured by both versions.

3DM 2 Reference
Note: 3DM 2 displays the capacity (in MBytes or GBytes) the
same way that Microsoft Windows and Linux operating systems
do: as 1KB = 1024 bytes. Previous versions of 3DM 1.x used the
1KB = 1000 bytes definition. Consequently capacities of units
listed under 3DM v 1.x may appear to be larger than they do under
3DM 2.
Status. The operational status of the unit: OK, Rebuilding, Initializing,
Verifying, Degraded, or Inoperable (missing drives). When a unit is
Rebuilding, Initializing, or Verifying, the percentage (%) complete is also
shown.

Figure 21. Controller Settings Page
The Controller Settings page appears when you choose Management >
Controller Settings from the menu bar.
The Controller Settings page lets you view and change settings that affect the
units on the controller specified in the drop-down list on the menu bar.
Background Task Rate
The Background Task Rate fields let you change the balance of background
tasks (rebuild and verify) and I/O performed by the controller.
9000-series controllers show separate settings for Rebuild Rate and Verify
Rate, as shown in Figure 21. 7000- and 8000-series controllers show only one
setting for Task Rate; it applies to both rebuild and verify rates.This rate is not
persistent following a reboot for 7/8000.
The 5 radio buttons let you set the ratio at which rebuilds and verifies are
performed. The furthest left buttons set the firmware to the fastest rebuild and
verify settings. This means, maximum processing time will be given to
rebuilds or verifies rather than I/O. The furthest right buttons set the firmware
to the slowest rebuild and verify settings, giving maximum processing time to
I/O.

Unit Write Cache
You can enable or disable write cache for each unit.3DM lists each unit on the
controller specified in the drop-down list on the menu bar, and shows you
whether the write cache is currently enabled or disabled for it.
Write cache is a combination of the physical hard drives’ write cache as well
as the controller’s memory, depending on what type of unit you are using.
For 9000-series controllers, a Disable Write Cache on Unit Degrade setting
can be set in 3ware BIOS Manager (3BM). You can see if this setting is
enabled in the Other Controller Settings field at the bottom of this
Controller Settings page. If Disable Write Cache on Unit Degrade is
enabled, upon degrade of a unit, the write cache will automatically be
disabled, even if you enable write cache in the Unit Write Cache field.
For additional information, see “Enabling and Disabling the Unit Write
Unit Policies
For units on 9000-series controllers, you can enable or disable two policies:
Auto-verify and Continue on Source Error During Rebuild. 3DM lists
each unit on the controller specified in the drop-down list on the menu bar,
and shows you whether the policies are currently enabled or disabled for each
unit.
This section does not appear for 7000- and 8000- series controllers.
Auto-verify. The Auto-verify policy causes verify tasks to be performed
repeatedly during a scheduled verify window. When Auto-verify is disabled,
verify is not initiated automatically by the controller. Verify can still be started
manually with 3DM, 3BM, or CLI. Once a manually-started verification is
complete, no further verify tasks for the unit is performed.
Continue on Source Error During Rebuild. This policy applies only to units
which are redundant. (For units which are not redundant, a check box is not
available.) When this policy is set, ECC errors are ignored when they are
encountered during a rebuild. When this policy is not set, a rebuild will abort
upon encountering an ECC error and the unit will be set back to Degraded.
Since this option could result in the loss of some source data in the event of
source errors, select this option only if you want to ensure that a rebuild will
complete successfully without manually intervention. If the rebuild fails and
Continue on Source Error During Rebuild is not selected, then you have
the option to start a rebuild manually. It is recommended that a file system
check be executed when the rebuild completes.

v 1.x and the “ignoreEcc” option in the CLI.
Other Controller Settings
For 9000-series controllers, the Other Controller settings displays information
about additional settings that can only be changed in the BIOS (3BM). For
more information see “Setting Policies for a Controller through 3BM” on
This section does not appear for 7000- and 8000- series controllers.
Number of Drives Per Spin-up. Number of drives that will spin up at the
same time when the controller is powered up. (This setting only applies when
the feature is supported by the disk drives and has been enabled in 3BM.)
Delay between Spin-ups. The delay between drive groups that spin up at one
time on this particular controller.
Export JBOD (Unconfigured) Disks. Indicates whether unconfigured disks
(JBODs) should be exported to the operating system. By default, this setting
is disabled. For more information about this feature, see “Exporting JBOD
Disable Write Cache on Unit Degrade. Indicates whether write cache will
be automatically disabled on a unit if it becomes degraded. After the unit is

Download from Www.Somanuals.com. All Manuals Search And Download.
3DM 2 Reference
The Scheduling page lets you view and change the schedule for tasks that
affect all units on the controller specified in the drop-down list on the menu
bar, including:
■ Rebuild tasks (also applies to initialization tasks)
■ Verify tasks (also applies to media scans)
■ Self-tests
You can also enable or disable use of the schedule for Rebuild and Verify
tasks by selecting either Follow Schedule or Ignore Schedule. When these
schedules are set to be ignored, these tasks can be performed at any time, and
are not restricted to the scheduled times.
Note: Scheduling of these tasks is only available on the 9000-
series controllers.
For details about the different background tasks, see “About Background
About Task Schedules
Each type of task may be scheduled for up to 7 times per week. This limits
active initializing, rebuilding, verifying, and testing of a unit to the times you
specify, so that the task does not interfere with peak I/O times.
If all 7 schedule slots are filled, you must first remove one or more schedule
times before you can add another.
You may set schedule times whether scheduling is set to be followed or
ignored. This is useful if you want to temporarily disable the schedule.
If you remove all the schedule times for a particular background task,
initializations and rebuilds will run anytime, as they are needed. Verify will
only run if started by the CLI or if the Verify Unit button is clicked.
For information about adding and removing schedules, and setting schedules
to be followed or ignored, see “Scheduling Background Tasks” on page 114
About Self-tests
Unlike scheduling of rebuilds and verifies, scheduling of self-tests is always
followed. To disable self-tests you either remove all schedule times, or
uncheck the tests listed in the Tasks column.
Note: Only the checked tasks will be run during the scheduled
times. If none of the tasks are checked, self-tests will never run,
even if you have scheduled time slots set.

Two self-tests can be scheduled:
Upgrade UDMA mode. This test checks the speed at which data transfer to
drives is occurring, to see if the UDMA mode can be increased. (If you are
already running at the fastest UDMA mode, then this self-test has no effect.)
The UDMA mode can become downgraded in the event that cable CRC errors
are encountered, requiring multiple retries to read sectors. In severe cases, the
UDMA mode may be downgraded from ATA 150 to ATA 133, to ATA 100, to
66, to 33.
This check is also done every time the system is booted.
UDMA mode does not apply to SATA.
Check SMART Thresholds. This test checks to see whether SMART
thresholds have been exceeded.
The SMART thresholds indicate when a drive is likely to fail, based on the
number of errors that have been recorded through SMART (Self-Monitoring,
Analysis and Reporting Technology).
If any of the disk drives have detected a “threshold exceeded” condition, then
an AEN is logged to the 3DM Alarms page. Moreover, if anything unusual is
found during any self-test, it will be logged as an Alarm.

The Maintenance page lets you perform maintenance tasks on existing units
on the current controller (shown in the drop-down list on the menu bar), and
lets you create new units by configuring available drives.
Rescan Controller
Use the Rescan Controller button to have 3DM scan the available drives in
the controller and update the list of available drives shown. This is useful in
variety of maintenance tasks. For example, if you physically plug in a drive
and want the controller to recognize the newly plugged in drive.
Note: If you unplug a drive without first removing it through 3DM,
Rescan will not recognize it as gone unless the drive was in use or
until it is required by the system. Always use the Remove link to
remove a drive before unplugging it.

3ware Disk Manager (3DM 2)
Warning: Removing or adding drives which are not in hotswap
carriers can result in a system hang or may even damage the system
and the drive.
In 9000-series controllers, rescan checks empty ports for newly plugged in
drives. If those drives were previously part of a 3ware RAID configuration
and they still have valid DCB (Disk Configuration Block) information on
them, the controller tries to piece them back together into a working unit. If a
working unit can be formed, it will appear in the Unit Maintenance list when
the scan is complete, and the operating system will be notified of the unit. In
Linux or FreeBSD, a device node will be associated with each unit created. In
Windows the device manager will reflect the changes under the disk drives
icon. This process is known as importing drives.
If new drives do not have any data indicating they were previously part of a
3ware RAID configuration, they will appear in the Available Drives list.
In addition, if there is a unit with the status Inoperable before a rescan (for
example, a RAID 5 unit missing 2 or more drives), and a rescan finds drives
that complete the unit, the inoperable unit will become a valid unit.
Note: In 8000-series controllers, only JBOD units can be removed
and rescanned while keeping the data intact. Clicking Rescan
Controller after removing units other than a JBOD unit (e.g.
RAID 5) will cause the drives that make up the unit to be
seen as individual available drives; they will not be pieced
together to form a unit. This is unlike the 9000 series
controllers, which will piece together the unit for you and
display the drives as a unit. If you still want to use the drives
together as a unit, restart the computer before creating a new
unit with those drives. Creating a new unit with those drives
will destroy any existing data on them. After you restart, the
8000 will again see the drives as a valid unit.
Unit Maintenance
The Unit Maintenance section of the page lists all existing units on the current

Remove Drive. The Remove Drive link removes a drive from the controller
so that you can safely unplug it. In the Unit Maintenance section, this link is
only provided for drives that can be safely removed without creating an
inoperable unit. (For example, a RAID 5 missing 2 or more drives or a RAID
0 missing 1 or more drives would become inoperable.) If you remove a drive
from a redundant unit, the unit will become degraded. Once a unit has become
degraded, additional drives cannot be removed without making it inoperable,
so no Remove Drive link will display.
Warning: Physically removing drives which are not in hotswap
carriers can result in a system hang or may even damage the system
and the drive.
Maintenance Task Buttons
Below the list of units, a row of task buttons lets you preform maintenance
and configuration tasks related to the unit. Before clicking one of these
buttons, select the appropriate unit.
Verify Unit. Puts the selected unit in verifying mode. If verify scheduling is
enabled on the Scheduling page, the unit will not start actively verifying until
the scheduled time, and the status will indicate “Verify-Paused.” (The Unit
Details page will indicate whether a unit is actively verifying.) If verify
scheduling is not enabled, clicking Verify Unit begins the verification
process.

3ware Disk Manager (3DM 2)
If the unit you selected to verify is a redundant unit, the redundancy of the unit
will be verified. For example it will check parity for a RAID 5 or check data
consistency for a RAID 1. If the unit you checked is not a redundant unit,
verify will do a surface scan of the media. During verification, I/O continues
normally. For RAID 0, single disks, JBODs, and spares, there is only a slight
performance loss. For redundant units, you can set the background task rate
on the Controller Settings page to specify whether more processing time
should be given to verifying or to I/O.
While a unit is verifying, the status changes to Verifying and a Stop Verify
link appears in the right-most column of the Unit Maintenance table.
Note: If the unit has not previously been initialized and you click
Verify Unit, the initialization process starts. Initialization cannot
be halted, so no Stop Verify link appears. (Initialization can be
paused, however, through Scheduling. Initialization follows the
Rebuild schedule, so turning on scheduling for Rebuild will pause
initialization, as well.) For more information about initialization,
Rebuild Unit. Replaces a degraded drive in a degraded unit with an available
drive and begins rebuilding the RAID. When you select a degraded unit and
click Rebuild Unit, a dialog box listing available drives appears, so that you
can select the drive you want to use. If the degraded unit has more than one
degraded drives (for example, a RAID 10 where both mirrored pairs each
have a degraded drive), you will repeat this process a second time.
If rebuild scheduling is enabled on the Scheduling page, the unit will not start
actively rebuilding until the scheduled time, and the status will change to say
“Rebuild-Paused.” (The Unit Details page indicates whether a unit is actively
rebuilding.) If rebuild scheduling is not enabled, the rebuild process will
begin right away.
Remove Unit. Removes a selected unit and allows you to unplug the drives
and move the unit to another controller. the data on the unit remain intact.

Caution: Before you click Remove Unit, make sure the unit you
are removing is unmounted and no I/Os are being issued. (For
example, make sure you are not copying files to the unit, and make
sure that there are no applications with open files on that unit.)
If a unit is not unmounted and you remove it, it is the equivalent of
physically yanking a hard drive out from under the operating sys-
tem. Resulting behavior depends on which operating system you
are using and what kind of I/O is being done, however you will
typically see really bad results, bad errors, and most likely a reset
of the controller or a system hang.
To unmount a unit under windows, use Administrative Tools >
Computer Management > Disk Management. In the Computer
Management window, right-click on the partition and Remove the
logical drive letter associated with the unit.
To unmount a unit under Linux, unmount the mount point to where
the RAID unit is mounted. For example, if you want to remove unit
0 and you know that 0 corresponds to /dev/sdb, you should
unmount all partitions for sdbx (where x is the number of the parti-
tion).
umount /dev/sdbx
For FreeBSD, the command would be
umount /dev/twedx
When you click Remove Unit, you will be asked to confirm that you want to
proceed. When you confirm the removal, the unit number and information
will be removed from 3DM. (Units created in the future can reclaim this unit
number.)
The operating system is notified that the unit was removed. In Linux the
device node associated with this unit is removed. In Windows the Device
Manager will reflect the changes under the disk drives icon.
Information about the unit remains intact on the drives. This allows the drive
or drives to be reassembled into a unit again on this controller, or if moved to
another controller.
Warning: Physically removing drives which are not in hotswap
