Password protection protects tapes by setting a password indicator in the standard tape labels. An X'F1' appears in the data set security byte in the IBM® Standard Data Set Label 1 (HDR1, EOV1, and EOF1) of each backup, migration, and dump tape. Single file format tapes have only one data set label.

Guideline: IBM does not suggest the use of data set password protection alone, because it provides less protection than the use of RACF®. However, it may be used in conjunction with RACF DATASET Class Profiles. See z/OS DFSMSdfp Advanced Services for a discussion of password protection.
