Place the system in restricted state

If all of the subsystems, including the controlling subsystem are ended, the system goes into a restricted condition. You can place the system in a restricted condition by using one of two commands from an interactive workstation.

Command: End Subsystem with the *ALL parameter (ENDSBS SBS(*ALL))

Command: End System (ENDSYS)

Important: The ENDSBS or ENDSYS command should be issued from an interactive job in the controlling subsystem, and only from a workstation whose entry in the controlling subsystem description specifies AT(*SIGNON). The interactive job from which the command was issued remains active when the controlling subsystem goes into a restricted condition. If the job issuing the command is one of two jobs that are active at the workstation (using the System Request key or the TFRSECJOB command), neither of the jobs is forced to end. However, the controlling subsystem does not end for the restricted condition until you end one of the jobs. Suspending group jobs also prevents the controlling subsystem from ending (until the group jobs are ended).

When the system is in the restricted condition, most of the activity on the system has ended, and only one workstation is active. The system must be in this condition for commands such as Save System (SAVSYS) or Reclaim Storage (RCLSTG) to run.

Some programs for diagnosing equipment problems also require the system to be in a restricted condition. To end the restricted condition you must start the controlling subsystem again.
