A volume group is a group of volumes
that have some common physical location or characteristic, such as being
in the same library, at the same offsite location, having the same media
density, or the like. There may be more than one group in a location, however,
all media in a volume group must be in the same location.
Q: How do I add a volume group?
A: You can add a volume group when
you are adding new volumes. When adding a single volume and specifying
the volume group, simply type in the name of the new volume group you wish
to create.
