About adding standalone volumes

Standalone volumes are the volumes that reside in the drives that are not in a robot or are allocated for standalone drives.

Because NetBackup does not label volumes until it uses them, you can add volumes even though they do not reside in a drive. The additional volumes are available for use if the volume in a drive becomes full or unusable. For example, if a volume in a standalone drive is full or unusable because of errors, NetBackup ejects (logically) the volume. If you add other standalone volumes, NetBackup requests that volume; NetBackup does not generate an out of media error.

The easiest way to add standalone volumes is to use the Volume Configuration Wizard. Then, when NetBackup requests one of the volumes, insert it into the standalone drive and NetBackup labels it.

The DISABLE_STANDALONE_DRIVE_EXTENSIONS option of the nbemmcmd command can turn off the automatic use of standalone volumes.
