Ensure that the 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 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.

Run the appropriate diagnostics tests. See "Running the System
Diagnostics" on page 173.

Reseat the controller card in the expansion card slot.

Close the system. See "Closing the System" on page 91.

Place the system upright and on its feet on a flat and stable surface,
reconnect the system to the electrical outlet, and turn on the system and
attached peripherals.
