CA TLMS supports the following tape data structures:
These are volumes that contain two or more data sets. One data set is identified as the controlling data set (CDS) so that you can define retention for the most critical data set on the volume. This defaults to the first data set on the volume. To change this, see the section Changing the Controlling Data Set.
VOL1 DSN1 (CDS) DSN2
Data sets start on a base volume and are continued on one or more additional volumes. CA TLMS automatically chains together all volumes associated with a data set so that the retention criteria you define for the data set controls all of its volumes.
VOL1 DSN1
VOL2 DSN1
Any volume in a multivolume data set can also have multiple data sets.
VOL1 DSN1 DSN2
VOL2 DSN2
VOL3 DSN2 DSN3
