Errors can occur when media is mounted for NetBackup jobs. Depending on the type of error, the request queues or it is canceled.
When the mount request is queued, an operator-pending action is created and appears in the Device Monitor.
When a mount request is automatically canceled, NetBackup tries to select other media to use for backups. (Selection applies only in the case of backup requests.)
Many conditions lead to a mount request being automatically canceled instead of queued. When a media mount is canceled, different media is selected so that the backup is not held up.
The following conditions can lead to automatic media reselection:
The requested media is in a drive not accessible to the media server.
The requested media is in an offline ACS LSM (Automated Cartridge System Library Storage Module). (ACS robot type only.)
The requested media has an unreadable barcode. (ACS robot type only.)
The requested media is in an ACS that is not accessible. (ACS robot type only.)
The server encountered an internal error or misconfiguration and was unable to complete your request.
