Cancelled Media Mount Errors

When automatically cancelled, NetBackup tries to select other media to use for backups. (This applies only in the case of backup requests.)

Many conditions lead to the automatic cancelling of the mount request instead of queuing a mount request. This leads to reselection of different media and a greater likelihood that the backup is not delayed.

The following conditions can lead to automatic media reselection:

• When the requested media is in a DOWN drive.
• When the requested media is misplaced.
• When the requested media is write-protected.
• When the requested media is in a drive not accessible to the media server.
• When the requested media is in an offline ACS LSM (Automated Cartridge System Library Storage Module). (ACS robot type only.)
• When the requested media has an unreadable barcode. (ACS robot type only.)
• When the requested media is in an ACS that is not accessible. (ACS robot type only.)
• When the requested media has been otherwise determined to be unmountable.
