Checking Autochanger Notifications
NetWorker uses e-mail to send notices about NetWorker events. The software uses the
three Tape Mount Request notifications to inform you that the autochanger needs
attention, as listed below:
• Tape Mount Request 1 - displays a pending request for mounting a backup volume.
In most cases, the server is waiting for an operator to perform a routine task. This
notification is undefined so you can create your own notification message.
• Tape Mount Request 2 - sends a request for mounting a backup volume, using a
priority of critical. This message identifies that the sever has detected an error that
should be fixed.
• Tape Mount Request 3 - logs a message to the sys.log file for mounting a backup
volume, using a priority of alert. This message requires immediate attention.
The following situations also require attention:
• The volumes in the autochanger are 90% full.
• The autochanger needs more volumes to continue.
• The autochanger has a mechanical problem.
• The autochanger device needs cleaning.
• The cleaning cartridge in the autochanger needs replacing.
The Notifications resource contains tape mount and device cleaning request
notifications pertaining to autochanger operations. Refer to “Preconfigured
Notifications” in the Legato NetWorker Administrator’s Guide, UNIX Version, for more
information.
If the volume is loaded in the autochanger, NetWorker can automatically mount the
correct volume so that the recovery proceeds. If NetWorker requires volumes for a
recovery that are not loaded in the autochanger, you receive a notice in the Pending
window of the NetWorker Administrator program.
After you correct an autochanger problem, you might need to mount a volume before
continuing to back up or recover files. Check the Pending window in the NetWorker
Administrator program for messages.
Suggestions for Operating Autochangers
This section provides additional suggestions to help you use your autochanger and
backup media effectively and reliably.
Recycling Versus Adding More Backup Volumes
NetWorker can save files on volumes marked “appen” (appendable) in the Volumes
resource. If the volumes inside the autochanger are marked full, they cannot receive
additional backups.
You can perform one of the following options if a volumes is marked “full”:
• If you need to keep the volumes for long-term storage, remove the full volume
and replace it with new media.
