Look for
connection
errors with the
host and
network.
Check all cable connections. Ensure the SCSI bus is
properly terminated.
Ensure the SCSI host bus adapter card and the drivers are
compatible and correctly installed.
Ensure the host can identify the autoloader and drive.
Verify the
autoloader
hardware is
correctly
operating.
Run a Wellness Test from the autoloader front panel.
Ensure the LED on the front panel is not flashing amber.
Flashing amber indicates a hardware error. Check the hard
and soft error logs.
Verify the
software is
supported and
correctly
configured.
Ensure the backup software has the Loader Module or Changer
option to communicate with the autoloader robotics or use the
Stacker operating mode from the autoloader front panel.
Check the software configuration. Ensure the SCSI IDs
are correct on the backup software application.
Use a different backup software application (if available)
and see if a similar error occurs.
