Protecting multivolume data sets with discrete profiles

You can protect a multivolume data set with either a discrete or a generic profile. If a generic profile protects the data set, the fact that the data set is multivolume is irrelevant.

To create a discrete profile for a multivolume tape or non-VSAM DASD data set, you must define each volume of the data set to RACF®. RACF stores the volume serial numbers in the data set's profile. When the data set is extended to another volume or deleted from a volume, that volume's serial number is automatically added to or deleted from the data set profile.

Note: You cannot rename a multivolume non-VSAM DASD data set that is protected by a discrete profile. If the data set is protected with a generic profile, it can be renamed if the new name is also covered by a generic profile.
