Troubleshooting a Tape Backup Unit
1
Try using a different tape cartridge.
2
Ensure that the device drivers for the tape backup unit are installed and
are configured correctly. See your tape drive documentation for more
information about device drivers.
3
Reinstall the tape-backup software as instructed in the tape-backup
software documentation.
4
For external tape drives, ensure that the tape drive’s interface cable is fully
connected to the external port on the controller card. For internal tape
drives, check the cable connections:
a
Turn off the system and attached peripherals, and disconnect the
system from the electrical outlet.
b
Open the system. See "Opening the System" on page 59.
c
Reseat the controller card in the expansion card slot.
d
Ensure that the tape drive's interface cable is fully connected to the
tape drive and to the connector on the controller card (SAS or SCSI).
e
Ensure that a power cable is properly connected to the drive and to
the system board.
f
Close the system. See "Closing the System" on page 60.
5
For SCSI tape drives, verify that the tape drive is configured for a unique
SCSI ID number and that the tape drive is terminated or not terminated,
based on the interface cable used to connect the drive.
See the documentation for the tape drive for instructions on selecting the
SCSI ID number and enabling or disabling termination.
6
Run the appropriate online diagnostics tests. See "Using Online
Diagnostics" on page 127.
If you cannot resolve the problem, see
"Getting Help" on page 135
