New master keys automatically set when ICSF started

ICSF will automatically set new master key registers when ICSF is started if the current master key does not match the master key verification pattern (MKVP) in the key data set. When running with COMPAT(NO), the check of the new master key registers is made every time ICSF is started. When running with COMPAT(YES) or COMPAT(COEXIST), the check is only done when ICSF is started for the first time after an IPL.

The following conditions must be true:
  • The new master key register must be full (final key part loaded).
  • The MKVP of the new master key register must match the MKVP in the header of the CKDS or PKDS.
