To protect controlled datasets effectively, CA EPIC for z/VSE controls the tape volumes they reside on. CA EPIC for z/VSE also protects the tape volumes it controls. Every tape that contains an CA EPIC for z/VSE-controlled dataset is recorded in the DSN Catalog. Tapes are identified by volume serial number and controlled at the version level under the name of the dataset they contain. Tape volumes are cataloged individually, as they are used for controlled datasets or initialized with TSIDINIT. CA EPIC for z/VSE provides utilities to assist you in labeling, initializing, pooling, and vaulting controlled tapes. This chapter describes CA EPIC for z/VSE tape control and tape protection utilities.
