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
