Volume group property

If you specified a robot, select from a volume group already configured for that robot. Alternatively, enter the name for a volume group; if it does not exist, NetBackup creates it and adds the volume to it.

Stand-alone volumes are not assigned to a volume group.
NetBackup generates a name for robotic volumes by using the robot number and type. For example, if the robot is a TL8 and has a robot number of 50, the group name is 000_00050_TL8.
