Understanding Error States
Host Software and Media Errors
The library depends on several other components to operate correctly.
Errors that seem to be caused by the library often are a result of errors
on the host, the network, media, or with the backup software. When
troubleshooting the library, begin ruling out these components.
Use the following troubleshooting procedures to help determine if an
error is caused by the library hardware, host, or backup software. Use
the remote management card to troubleshoot media errors.
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 library and drive.
Verify the library
hardware is
correctly
operating.
Run a Wellness Test from the library 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.
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.
