Dump tape security considerations z/OS DFSMShsm Implementation and Customization Guide SC23-6869-01 |
||||||||||||||||||||||
Tape security options are the same for dump tapes, backup tapes, and migration tapes; however, there are some differences in implementation because DFSMShsm does not actually write on the dump tapes. Restrictions for changing the tape-security options apply to dump-tape processing, except that the same security options that were in effect at the start of a dump operation remain in effect for the duration of the dump operation, even though the options can be changed with the SETSYS command at any time. This restriction is because dump processing marks any partially filled tapes as full; they are never selected for additional dump output. See Table 1 for a list of options and SETSYS command attributes. Dump tapes have no restriction (unlike backup and migration tapes) about placing password-protected data sets on non-password-protected tapes. Attention: Dump tapes that are password protected by DFSMShsm cannot
be restored directly by DFSMSdss. Password-protected dump tapes must
be write protected (ring removed or cartridge knob set) before they
are mounted for restore processing.
