Use the following Media ID prefix

If the robot supports bar codes and the volume has readable bar codes, a prefix is not required because NetBackup creates media IDs automatically.

If either of the following conditions exist, specify a media ID prefix for any new media :

You can either select from a list or enter a prefix.

The list contains the following selections:

DEFAULT

If DEFAULT is selected, NetBackup performs the following actions:

  • Assigns the last MEDIA_ID_PREFIX entry as the default prefix if MEDIA_ID_PREFIX entries are defined in the vm.conf file.

  • Uses the letter A if no MEDIA_ID_PREFIX entries are defined.

NOT USED

If NOT USED is selected, the operation succeeds only if the robot supports bar codes and the volume has readable bar codes. NOT USED can be useful if you use bar coded volumes and want updates to fail when unreadable or missing bar codes are encountered.

Other prefixes

If MEDIA_ID_PREFIX entries are defined in the vm.conf file, they appear in the list.

To specify a prefix that is not in the list, enter the new prefix in the list box. NetBackup uses the prefix only for the current operation.

You can specify a prefix of one to five alphanumeric characters. NetBackup assigns the remaining numeric characters to create six characters. For example, if the prefix is NETB, the media IDs are: NETB00, NETB01, and so on.

Information about the vm.conf file is available.
