The SAVE and RESTORE menus have been enhanced in IBM i 7.4 with a new option to “Start controlling subsystem”.
Previously, the controlling subsystem always started when the save or restore operation is complete. Now the user can choose to not start the controlling subsystem, so the system stays in restricted state after the save or restore operation. This can be helpful if you want to install PTFs, perform system maintenance, or IPL the system. See the IBM i Knowledge Center: SAVE menu enhancements and Restore menu enhancements for more information.
