Troubleshooting an External SCSI Tape Drive
Problem
• Defective tape drive
• Defective tape cartridge
• Missing or corrupted tape-backup software or tape drive device driver
• Defective SCSI controller
Action
1 Remove the tape cartridge you were using when the problem occurred, and replace it with a
tape cartridge that you know works.
2 Ensure that the SCSI device drivers for the tape drive are installed and are configured
correctly. See "Installing and Configuring SCSI Drivers" in "Installing Drives."
3 Reinstall the tape-backup software as instructed in the tape-backup software documentation.
4 Ensure that the tape drive’s interface/DC power cable is connected to the tape drive and
SCSI controller card.
5 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 Server Administrator Diagnostics" in
"Running System Diagnostics."
7 Turn off the system and attached peripherals, and disconnect the system from the electrical
outlet.
