About media mount errors

Errors can occur when media is mounted for NetBackup jobs. Depending on the type of error, NetBackup adds the mount request to the pending requests queue or cancels the mount request, as follows:

Adds to the pending requests queue

When NetBackup adds the mount request to the queue, NetBackup creates an operator-pending action. The action appears in the NetBackup Administration Console Device Monitor. A queued mount request leads to one of the following actions:

  • The mount request is suspended until the condition is resolved.

  • The operator denies the request.

  • The media mount time out is reached.

Cancels the request

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, NetBackup selects different media so that the backup is not held up.

See When NetBackup selects different media.

When NetBackup selects different media

The following conditions can lead to automatic media reselection:

  • The requested media is in a DOWN drive.

  • The requested media is misplaced.

  • The requested media is write protected.

  • 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 requested media is determined to be unmountable.
