Loading, operating and terminating guest systems

Note on the initialization of guest systems

• Loading (IPL) for a guest system is executed (after the VM has been configured) by means of the VM2000 command /START-VM or in the SE Manager (VM selected) in the Operation tab by the action BS2000 IPL (see "Starting the guest system on a VM").

  On SU x86, the guest system can also be loaded using the SVP functions of the KVP console which is assigned to the VM (see the manual “Operation and Administration” [19]).

Notes on the operation of BS2000 guest systems

• The operation of the guest system on a VM (operating) normally takes place via KVP consoles (see "Operating the guest systems using BS2000 consoles").

  When BCAM is active in the guest system, logical consoles (e.g. via OMNIS) can be used with differentiated privileges for system operation in guest systems (see the “OMNIS/OMNIS-MENU” manual [12]).

  A guest system can also be operated using $VMCONS (see "Operating the guest systems (VC dialog via $VMCONS)").

  If the dialog system is ready for operation, operator commands can also be executed by user tasks with the OPERATING privilege.

• See "Monitoring under VM2000" on local measurements in the guest system.

Notes on the termination of BS2000 guest systems

• The guest system is shut down using the VM2000 command /SHUTDOWN-VM (see "SHUTDOWN-VM (Execute a shutdown in the guest system and for VM2000)"). As in native operation, it can also be shut down using the BS2000 command /SHUTDOWN (see the “Introduction to System Administration” [2]).

  BS2000 shutdown for a guest system can also be initiated using the SE Manager, VM selected, Operation tab, BS2000 Shutdown action.

• By means of the VM2000 command /DELETE-VM ...,CHECK-VM-STATE=*NO or /SHUTDOWN of the monitor system, the guest system is stopped regardless of the current state of the system. Files of the guest system may therefore be in an inconsistent state unless the guest system is terminated beforehand with /SHUTDOWN.

Information on status changes

The following status changes in the BS2000 guest system are indicated to the VM administrator by means of a VM2000 message:

• The guest system is ready for operation (VMS2050).

• The guest system has been terminated with /SHUTDOWN or has failed with SETS (VMS2051).

• The guest system is not ready for operation (/SHUTDOWN or SETS); a restart has been initialized (VMS2052).

• The active guest system was aborted with /RESET-VM or with /START-VM ...,CHECK-VM-STATE=*NO and restarted (VMS2051).

These messages are also distributed in the monitor system by means of routing code “9”.
