Host software and media errors
The autoloader depends on several other components to operate correctly. Many
errors that appear to be caused by the autoloader are often a result of errors on the
host, the network, or with the backup software.
When troubleshooting the autoloader, begin by ruling out these other components.
Here are some troubleshooting procedures to help determine if an error is caused
by the autoloader hardware, host, or backup software.
Verify the
autoloader
hardware is
correctly
operating.
Verify the
software is
supported and
correctly
configured.
Look for
connection
errors with the
host and
network.
Ensure the LED on the front panel is not flashing amber.
Flashing amber indicates a hardware error. Check the hard
and soft error logs.
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
Run a Wellness Test from the autoloader front panel.
Check the software configuration. Ensure the SCSI ID’s are
correct on the backup software application.
Use a different backup software application (if available) and
see if similar errors occurs.
Ensure the host can identify the autoloader and drive.
Ensure the SCSI host bus adaptor card and the drives are
compatible and correctly installed.
Check all cable connections. Ensure the SCSI bus is properly
terminated.
The table that follows describes error code qualifiers.
