Troubleshooting an External Tape Drive
Problem

Action
1
Remove the tape cartridge you were using when the problem occurred, and
replace it with a tape cartridge that you know works.

Ensure that the SCSI or SAS device drivers for the tape drive are installed
and are configured correctly. See your tape drive documentation for more
information about device drivers.

Reinstall the tape-backup software as instructed in the tape-backup
software documentation.

Ensure that the tape drive’s interface cable is fully connected to the tape
drive and the external port on the SCSI or SAS controller card.

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.
