Removal
Note: For dual half-height tape drive canisters, repeat the tape drive
power off process for both drives in the canister. If you do not
power down both tape drives before removing the tape drive
canister, operations in progress can be interrupted causing a
backup job to fail and/or leave a tape cartridge in one of the
tape drives.
Caution: Make sure the thumbscrews are loosened fully before
trying to remove the sub-plate.
Note: Native Fibre Channel drives and dual half-height drives do
not have a SCSI sub-plate. Continue with step 3.

8 Installing the New Tape Drive Canister
2Pull the SCSI sub-plate from the drive (see figure 7).
3Use a flat blade screwdriver to loosen the tape drive thumbscrew (see
figure 5).
4Pull the tape drive out of the library using care to move the SCSI cables
out of the way when the drive is removed.
Installing the New Tape Drive Canister 0
To install the new tape drive canister:
1Remove the SCSI sub-plate from the new tape drive:
aUse a flat-blade screwdriver to loosen the two thumbscrews on the
SCSI sub-plate (see figure 5).
bPull the SCSI sub-plate from the drive.
cSave the SCSI sub-plate.
Note: This disconnects the SCSI bus from the tape drive, but allows
the SCSI connectors on the sub-plate to remain connected. Do
not disconnect these cables.
Caution: Make sure the thumbscrew is loosened fully before trying
to remove the tape drive.
Note: If this is a native Fibre Channel tape drive, disconnect the Fibre
Channel cable prior to removing the tape drive.
Note: Each tape drive ships from Quantum with a version of library
firmware as well as drive firmware on the tape drive interface
PWA. When you install the tape drive, the library will check the
version of library firmware on the tape drive and verify if the
firmware is newer than the version currently running. If the library
firmware on the tape drive is newer than the version currently
running on the library, the OCP will prompt you with the option to
upgrade the library firmware.
Note: Native Fibre Channel drives do not have a SCSI sub-plate.
Continue with step 2.
Caution: Make sure the thumbscrews are loosened fully before
trying to remove the sub-plate.

Replacing the SCSI Sub-Plate 9
2Slowly insert the new tape drive into the library until the connectors are
seated.
3Tighten the tape drive thumbscrew using a flat-blade screwdriver.
4For SCSI tape drives, install the old SCSI sub-plate (still connected to the
SCSI bus) on the new tape drive. For native Fibre Channel tape drives,
reconnect the Fibre Channel cable to the tape drive.
5Tighten the two sub-plate thumbscrews using a flat-blade screwdriver.
6Return power to the drive by setting the Drive Power option to ON (refer
to the Drive Operations Screen on page 5 for OCP instructions and Drives
Page on page 6 for GUI instructions).
The host detects the presence of the tape drive automatically.
7If the host does not detect the presence of the tape drive, check the drive
SCSI ID (from the OCP, select Setup, Cabinet, and Host bus to view the
SCSI IDs for the tape drives). If the drive SCSI ID is:
• Valid, the tape drive may be defective. Contact Customer Support.
• Invalid, the SCSI sub-plate has failed and needs to be replaced (see
Replacing the SCSI Sub-Plate).
The new tape drive is installed.
Replacing the SCSI Sub-Plate 0
To replace the SCSI sub-plate:
1Suspend all host activity on the SCSI bus.
2Power off the drive by setting the Drive Power option to OFF (refer to
Turning Off Drive Power on page 4).
3Disconnect the cables from the old SCSI sub-plate.
4Remove the old SCSI sub-plate from the drive:
Note: Installing a new Fibre Channel tape drive will require the
Fibre Channel host or SAN to remap the tape drive.
Caution: This procedure is necessary only if you performed the
procedure in Installing the New Tape Drive Canister, the tape
drive SCSI ID is invalid, and the host does not detect the
presence of the tape drive.

Troubleshooting 0
This section describes problems you may encounter during the tape drive
replacement procedure. Corrective information is provided to help you
resolve the problems.
Problem Corrective Action
The library or tape
drives do not respond
on the SCSI bus.
• Make sure each SCSI device on the same
SCSI bus has a unique address by checking
the SCSI IDs on the OCP and also ensure that
the last device is properly terminated.
• If possible, swap an operational drive with
the failed drive to see if this corrects the
communication problem (see Swapping a
Tape Drive). If the problem is corrected,
contact Quantum Customer Support to
obtaining a replacement tape drive.
One or more tape drives
fail to spin up during
start-up.
Check all SCSI cabling and termination at the
back of the library. If necessary, contact your
Quantum Customer Support about replacing
the tape drive.

12 Troubleshooting
Swapping a Tape Drive 0In the event that you have lost SCSI or Fibre Channel communication with a
tape drive, it is recommended that you swap the failed tape drive canister
with an operational tape drive canister. This will allow you to determine if a
failure has occurred in the library or tape drive. If the tape drive is operational
in the position of the failed tape drive, a failure has occurred in the tape drive.
If the tape drive is still inoperative in the new position, a failure has occurred
in the library. Contact Quantum Customer support for replacement tape
drives or library support.
Internal
Communication Error
Communication error between the robot
controller and system controller board has been
lost. Reboot the library. If the problem
continues, contact an authorized Quantum
Customer Support.
The host computer
cannot communicate
with the library.
This may be a SCSI bus time-out or a premature
disconnect problem.
• Check cable connections, SCSI addresses,
and termination.
• Restart the host and the library.
• If the host and library still are not
communicating, contact Quantum
Customer Support.
