Backup Jobs Failing - Physical Volume Library Drive not available.

Hi guys,

For the last couple of weeks, most of our backups have been failing with the error:

'Physical Volume Library Drive not available.'

This is happening for both Backup to Disk and Backup to Tape jobs.

The first error that I saw was (regarding the tape drive):

'The drive hardware is offline.

Please confirm that the drive hardware is powered on and properly cabled.'

There was also an error about low disk space on the Disk Storage (which I cleared up)

There was nothing (that I could see) wrong with the tape drive, but it was set to Offline in Backup Exec.

I changed it back to Online, but that did not seem to fix the issue. The jobs are still failing.

Is there something I can do to troubleshoot what the issue is?
