Industry:Software
A collection of tape volumes that contain private user data. A volume becomes part of the tape storage group when it is mounted to satisfy a scratch volume request for the storage group, or when it is entered into one of the tape libraries and assigned to the tape storage group by the cartridge entry process. The volume is removed from the tape storage group when it is returned to scratch after the data sets on it have expired. See also storage group.
Industry:Software
