Replacing a 5190 or 5194 Tape Drive CRU
b. Use the TSM Service Application to check the integrity of the modular tape
subsystem. You can use the TEST command to verify the operation of the
BEB. For a summary description, see The TSM Package (NonStop Himalaya
S-Series Servers) on page 5-7.
Replacing a 5190 or 5194 Tape Drive CRU
The tape drive CRU contains the tape drive, power supply, and, optionally, the
flush-mounted ACL. Components of the drive CRU cannot be repaired by customers.
If a component fails, the entire drive CRU must be replaced.
If you are replacing a 5190 tape drive CRU with a 5194 tape drive CRU:
•
Verify that the system is running a D30.01+ or later D3x release.
•
Firmware for the controller and tape drive must also be installed during the update
to the operating system. To avoid unreliability in the drive CRU you are installing,
use the most recent version of firmware.
No configuration changes are required.
Removing a Tape Drive CRU
After ordering a replacement tape drive CRU, use the following procedure to remove
an inoperative tape drive CRU.
1. Use the UNLOAD button or software commands to unload any cartridge that might
be loaded in the tape drive. If the drive CRU has an ACL, be sure to remove the
cleaning cartridge from the ACL. See Removing a Cleaning Cartridge From an
ACL on page 6-11.
2. Shut down the application software that uses the affected tape drive. You must
bring down both drives if you are using a BEB and the BEB serves two drives.
3. Shut down the path to the affected tape drives:
•
For NonStop Himalaya K-series servers, use PUP as follows:
1>PUP
#DOWN $TAPE1
#DOWN $TAPE2
#EXIT
•
For NonStop Himalaya S-series servers, use SCF as follows:
1>SCF
->STOP $TAPE1
->STOP $TAPE2
->EXIT
WARNING. When it includes an ACL, the tape drive CRU weighs 75 pounds (34 kilograms).
To avoid strain or injury, always use at least two people to lift the drive CRU out of the module.
