To password protect a data set on a tape volume containing other data sets, password protect all the data sets on the volume. (Standard labels—SL, SUL, AL, or AUL—are required. For definitions of these label types and the protection-mode indicators that can be used, see z/OS DFSMS Using Magnetic Tapes.)

If you issue an OPEN macro instruction to create a data set following an existing password-protected data set, the password of the existing data set will be verified during open processing for the new data set. The password supplied must be associated with a PWWRITE protection-mode indicator.
