A FORCE start will be required since the new CP_Owned list does not match the CP_Owned list that was saved in the checkpoint area when you shut down your system. The spool files are restored from the warmstart area during IPL, so they should be ok. You do risk losing information that was saved in the checkpoint area that hasn't been processed by the time the difference in the CP_Owned list is detected. In any event, I agree that a spool file backup is a good idea before attempting this change. John Franciscovich z/VM Development
