Shutdown in the monitor system

VM2000 operation is also terminated when the monitor system is shut down using the BS2000 command /SHUTDOWN (see the “Introduction to System Administration” [2]) or by the action BS2000 Shutdown for the monitor system in the SE manager.

Before the monitor system is terminated, the operator should terminate each guest system by means of the BS2000 command /SHUTDOWN. The operator of the monitor system must use the VM2000 command /SHOW-VM-RESOURCES to check if only the monitor system is actually still active.

At /SHUTDOWN of the monitor system with MODE=*END the following actions are also executed by VM2000:

• /DELETE-VM for all VMs which are still initialized, irrespective of the current system state (CHECK-VM-STATE=*NO)

• Accounting for the monitor VM

• Detaching of the attached extra CPUs

	On SU /390, all persistent VM definitions are updated by VM2000. The non-persistent VM definitions are deleted. These also include the VM definition of the monitor VM. For this action BCAM must still be active in the monitor system. On SU /390 use of the /SHUTDOWN MODE=*QUIET or /BCEND command should therefore be avoided in the monitor system when shutting down VM2000.
	VM definitions are administered by X2000 on SU x86. No action by VM2000 when shutdown takes place.

In the case of /SHUTDOWN of the monitor system with MODE=*END(RESTART=*YES(...)) or MODE=*END,MESSAGE=C'*RESTART' (with restart option), the guest systems and (on SU /390) the VM2000 hypervisor remain active. The monitor system is reloaded. VM2000 performs the accounting for the monitor VM before the monitor system is restarted.

The guest systems are informed of the restart of the monitor system. Message NRTV002 (“Monitor system not ready. Restart has been initiated”) is output on the guest system BS2000 console. When the monitor system reaches SYSTEM READY again, message NRTV003 (“Monitor system ready again”) is output.

In the case of /SHUTDOWN with restart, the monitor system must be prepared for automatic restart (see the “Introduction to System Administration” [2]).

In the event of an error (abnormal termination of the monitor system without a restart), VM2000 operation can be terminated by shutting down all the guest systems with /SHUTDOWN or by the action BS2000 Shutdown in the SE manager.
