Drive Installation or Replacement  
Instructions  
This guide provides instructions for either installing an additional drive or  
replacing an existing drive in a Spectra T200, T380, T680, T950, or TFinity  
library (the library).  
Illustrations The replacement drive that you received may not look  
exactly like the drives shown in this document.  
Most of the figures in this guide show the Spectra T380 library. The relative  
locations of the components and the procedures are the same for the other  
libraries unless otherwise indicated.The differences are indicated by  
library type; for example:  
ƒ Spectra T200, T380, or T680—items indicated with this text refer to any  
one of these three libraries.  
ƒ Spectra T950 and TFinity—items indicated with this text refer to  
either of these two libraries.  
User Interface Updates The BlueScale interface changes as new features  
are added or other modifications are made between firmware revisions.  
Therefore, the user interface screens on your library may differ from those  
shown in this document.  
Drive Bay Assemblies Each drive is mounted on a drive sled which is  
installed in a drive bay assembly (DBA) in the back of the library. If there  
are no empty drive bays in your library, you must install a new DBA to  
accommodate additional drives. Backups cannot continue while you install  
the new DBA and drive(s).  
Tape Drive Support This table shows the tape drives supported by the  
individual libraries.

PREPARE FOR MAINTENANCE  
Make sure you fulfill the prerequisites described in this section and  
familiarize yourself with all the sections in the document before starting.  
Continuing or Stopping Backups  
Use the following guidelines if you are installing or replacing a drive in a  
drive bay assembly (DBA) already in the library.  
Method  
Description  
QIP-attach drives  
(all libraries)  
Backups running to all other drives in the library (or partition) can safely  
continue while you install a new drive or replace an existing one.  
Direct-attach SCSI  
drives  
(Spectra T200,  
T380, T680)  
If multiple directattach SCSI drives are daisychained on the same SCSI bus,  
adding or removing a drive interrupts communications on the bus. Stop backup  
operations to all of the drives in the daisy chain. Spectra Logic recommends  
shutting down and powering off the host computer before replacing a drive.  
Note: Both the T950 and the TFinity require a QIP for directattach drive  
configurations.  
Direct-attach Fibre  
Channel drives  
(Spectra T200,  
T380, T680)  
Backups running to other drives in the library (or partition) can safely continue  
while you install a new drive or replace an existing one, unless the drive you are  
replacing is the one exporting the library (that is, providing the robotic control  
path for the partition). If the drive you are replacing provides the control path  
for the robotics, stop backup operations to the partition.  
Note: Both the T950 and the TFinity require a QIP for directattach drive  
configurations.  
Note: Selecting a drive to provide the robotic control path is part of configuring a partition. Refer to  
the individual User Guide for more information.  
Ensuring ESD Protection  
The repair environment for the library must be free of conditions that  
could cause electrostatic discharge (ESD). To protect the library from ESD,  
follow these procedures:  
ƒ Place a static protection mat on the work surface used while removing  
and installing library components. Use a 1megaohm resistor to ground  
the static protection mat.  
ƒ Wear a static protection wrist band whenever you handle library  
components that have been removed from their antistatic bags. Connect  
this wrist band to the static protection mat or to other suitable ESD  
grounding.  
ƒ Keep all components in antistatic bags when not in use.

Your backup software, the library, or both may indicate a drive problem.  
First, identify the problem drive, then check the Drives screen on the  
library user interface for the drive identifier, and finally, write down the  
drive identifier for use in a later section.  
Note: If your library has multiple partitions, use your backup software  
and the Partition Settings screen to identify the malfunctioning  
drive.  
Drives are identified in the librarys BlueScale user interface using the  
format shown in the following sections. You can also access the back of the  
library and look for the drive sled status light that blinks amber.

REPLACE OR INSTALL A DRIVE  
This section describes how to replace an existing tape drive or install an  
additional tape drive, and contains these steps:  
ƒ Preparing the Library (for replacement or installation)  
ƒ Accessing the Drives on page 10 (for replacement or installation)  
ƒ Installing the Drive on page 14 (for replacement or installation)  
When replacing a drive, the new drive must be the same “type” as the one you  
replace.  
Important  
If the drive to be replaced is the only drive in the partition, the existing partition will  
be deleted.  
Preparing the Library  
Drive Replacement Preparation  
This section describes how to prepare to replace a drive in the library.  
Note: If you are installing an additional drive, rather than replacing a  
drive, skip to Drive Installation Preparation on page 10.  
If the malfunctioning drive contains a cartridge, attempt to use the  
BlueScale user interface to move the cartridge to an empty slot before  
performing the steps in this section. See the individual User Guide for  
instructions. If you are unable to remove the cartridge, continue with the  
replacement without removing the cartridge.  
After you determine which drive needs replacing, follow these steps to  
shut down the drive so that you can remove it from the library.  
1. If the drive is attached to a QIP or if it is a directattach Fibre Channel  
drive, skip to Step 2.  
If the drive a directattached SCSI drive, Spectra Logic recommends  
shutting down and powering off the host computer before replacing  
the drive  
Improperly removing a device from a SCSI bus can cause a host computer to crash.  
If you decide to leave the host running, Spectra Logic is not responsible for any  
damage to data or equipment.

install each drive.  
ƒ If the library includes QIPs or bus expansion modules—a drive  
must be installed the same DBA as the QIP or bus expansion  
module that will connect it to the network (or SCSI bus).  
ƒ If the library uses directattach Fibre Channel drives—installing the  
drives sequentially, beginning with the next available drive bay  
simplifies the configuration. For example, if drive 1 is in drive bay 1,  
install drive 2 in drive bay 2, and so forth. The T950 and TFinity  
libraries do not allow directattach drive configurations.

drives or if you are not planning to daisychain multiple  
directattach SCSI drives on the same SCSI bus, proceed to  
Testing the Drive on page 21.  
ƒ Both the T950 and the TFinity require a QIP for directattach  
drive configurations.

Spectra T200, T380, T680, T950, or T-Finity Library  
Complete the Procedure  
Overview Drives can be daisychained together to add multiple drives to a  
partition. If your library configuration includes directattach SCSI drives  
and you plan to daisychain two or more drives in a DBA on a single SCSI  
bus, you must connect the drives and the bus expansion module before  
you begin configuring partitions. Read the individual User Guides to learn  
more about the bus expansion module and the role it plays in the library.  
Note: Do not connect the bus expansion module to the host until after  
you finish configuring the partitions.  
Single SCSI BUS Configuration Up to four drives in a single DBA can be  
daisychained on a single SCSI bus. Keep in mind that each drive increases  
the total length of the SCSI bus. Daisy chaining all four drives in a DBA  
results in an internal bus length of approximately 20 feet (6 meters), which  
must be subtracted from the maximum allowed length of 39 feet (12  
meters) for an LVD SCSI bus.  
Note: A maximum of 16 devices, including the four drives in a DBA,  
can be connected to a single wide LVD SCSI bus. Attaching more  
than two devices to a single SCSI bus can potentially have a  
negative impact on the performance of all devices on the bus.  
Figure 13 illustrates daisy chaining all four drives in a DBA on a single  
SCSI bus and connecting them to one host.

Connecting the Cables  
Two SCSI Bus Configuration Figure 14 illustrates daisy chaining the four  
drives in a DBA on two separate SCSI buses and connecting them to two  
hosts. This type of cabling is used when multiple hosts will be sharing the  
library resources. The library is typically divided into partitions, as  
described in the librarys User Guide. Each partition is dedicated to a  
different host.  
Note: Always make sure that the SCSI bus is terminated by installing a  
terminator either on the drive or on the bus expansion module.

Determine which drives in the DBA you want to daisychain on the same  
SCSI bus, then follow these steps to connect the drives to each other:  
1. Remove the SCSI terminator from each drive (see Figure 15).  
Terminator  
Figure 15 The SCSI terminator on a SCSI drive sled.  
2. Refer to the cabling examples on page 18 and page 19, then use SCSI  
cables to connect the drives together, as appropriate for your desired  
configuration. Use the shortest possible cable that does not require  
making tight bends in the cable.  
3. Install a SCSI terminator to the appropriate SCSI connector on the bus  
expansion module (refer to the cabling examples on page 18 and  
page 19).  
Connect the Fibre Channel Cables  
This section only applies to LTO3 and LTO4 Fibre Channel drives.  
1. Remove the protective plugs from the Fibre Channel port(s) on the  
drive.

1. Power on and restart the host computer, if you powered it off.  
2. Determine whether your backup software and drive are  
communicating properly.  
a. Use the software to write several megabytes of data using the newly  
installed drive.  
b. Perform a comparison check on the backup data to confirm that it  
was written correctly.  
Installing the Cover or Securing the Rear Door  
Spectra T200 or T380 Replace the protective cover after you complete the  
installation.  
1. Lift the cover and align it so that the two nuts extending from the back  
of the cover fit into the corresponding holes on either side of the chassis  
(Figure 5). If the cables to the drives and QIPs installed in the library are  
routed from the:  
ƒ top of the library, make sure that they fit into the cutout in the top of  
the cover.  
ƒ bottom of the library, make sure that they fit into the cutout in the  
bottom of the cover.  
Make sure that cables are not pinched between the cover and the chassis.  
Caution  
2. Using your fingers or a #2 Phillips screwdriver, tighten the two screws  
to secure the bottom of the cover to the chassis (see Figure 4 on  
page 11).  
Spectra T680 Close and lock the protective door on the back of the library  
rack (see Figure 6 on page 11).  
Spectra T950 or T-Finity Close and lock the protective doors on the back of  
the library (see Figure 7 on page 12).  
Adding the Drive to a Partition  
ƒ Replacement drive—If you replaced a drive, the new drive is  
automatically added to the partition of the old drive.  
ƒ New drive—If you installed an additional (new) drive, you need to add  
it to a partition before you can begin using it for backup operations.  
Refer to the individual User Guide for instructions.

Return the Component  
Restarting Backups  
Use your backup software to restart any backup processes that had been  
running to the replaced drive. This restart ensures that the software  
recognizes the drive as working and available.  
RETURN THE COMPONENT  
Return Guidelines  
Unless Spectra Logic Technical Support informs you otherwise, return the  
defective component to Spectra Logic following the guidelines in the next  
section. If Spectra Logic Technical Support informs you that the component  
does not need to be returned, dispose of it in a manner appropriate for  
your company guidelines.  
Return Procedures  
After you complete the replacement procedure, return the defective  
component using ALL the packaging that the replacement component  
arrived in (including any antistatic bags or foam inserts).  
Severe damage can occur if the component is not packaged correctly, and you may  
be invoiced if it is received with damage due to improper or insufficient packaging.  
Caution  
Use the return label and instructions that were included with the  
replacement component when preparing to ship the replacement part. If  
you cannot locate these, contact Spectra Logic for another copy (see  
Contacting Spectra Logic on page 2). The return label and RMA printed on  
it are used to associate the returned part with your account. To avoid being  
invoiced for failure to return the part, do not ship the part back without the  
RMA return label.
