sub-plate (see figure 7).

Figure 5 Tape Drive

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.
