Verifying CA Tape Encryption › Dump an Encrypted Tape

Dump an Encrypted Tape

You may want to routinely dump encrypted tapes to verify that CA Tape Encryption is processing as expected. The IDCAMS utility, available in every z/OS system, provides multiple ways to dump the tape to verify its contents. CA Tape Encryption dynamically changes Standard Label (SL) tapes to Standard User Label (SUL) tapes to retain information on the encryption type and other data used to track and manage the encryption keys associated with the tape.

You can choose to dump:

• Only the encrypted tape data
• The encrypted tape data, labels, user header labels, and user trailer labels

Both options are described below.
