If a backup control group contains a *SAVSYS special value or you issue the SAVSYSBRM command, BRMS will end all subsystems before the save operation begins. This ensures that no other activity can occur on the system during the save. The controlling subsystem is started after processing the last backup item in the backup control group. If you specify in your backup control group attributes that an IPL is to occur after the control group has finished processing, the controlling subsystem is not started as this is done as part of the IPL process.
By default, BRMS will restart the controlling subsystem. It is possible to prevent the controlling subsystem from starting after a *SAVSYS has been run. If you are using the SAVSYSBRM command, use STRCTLSBS(*NO). If you are using *SAVSYS in a backup control group, select option 9 from the Work with Backup Control Groups menu (WRKCTLGBRM) to work with subsystems to process and enter the following entry.
