Veritas NetBackup™ Administrator's Guide, Volume I

Use the following Media ID prefix (new media setting)

if the media has unreadable barcodes or if the robot does not support barcodes, by default NetBackup assigns media ID prefixes as follows:

  • If MEDIA_ID_PREFIX entries are defined in the vm.conf file, NetBackup assigns the last MEDIA_ID_PREFIX entry as the media ID prefix.

  • If no MEDIA_ID_PREFIX entries are defined in the vm.conf file, NetBackup uses the letter A as the media ID prefix.

To configure NetBackup to use a media ID prefix other than the default, select Use the following Media ID prefix field in the Advanced Robot Inventory Options dialog box and then click Browse. The Media ID Prefix dialog box appears.
