The tape drive is not seen

Verify the following:

     Termination is in place.

     There are no adapters in the connection between the device and the backup system.

     Shutdown both the backup system and the device. Power on the device and let it become idle/ready, then power up the backup system.

     Make sure that the tape device is LVD/SD.

     The backup system has a 68-pin high density connection for SCSI.

     Run the following command to verify that the system sees the SCSI device:

cat /proc/scsi/scsi

A tape drive status may display, even if the drive is empty. For example,

mt -f /dev/st0 status
