Complete this task to delete open systems volume groups, releasing
any assigned volumes for assignment to other volume groups.
If the number of volumes in this volume group is not zero, the volumes
that are assigned to this volume group go into an unassigned mode where they
are eligible for assignment to other volume groups.
Note: The volume group
is the link between the open systems volumes and the host attachments. If
you delete a volume group that is attached to a host attachment identifier,
the host attachment is not able to access the volumes.
