Startup procedure in the monitor system

Startup for the monitor system proceeds in the same way as in native operation of BS2000, apart from some additional actions for VM2000.
The “Introduction to System Administration” [2] provides a more detailed description.

	On SU /390, the startup of the monitor system is terminated if initialization of VM2000 is faulty.
	On SU x86, the startup of the monitor system is continued even if initialization of VM2000 is faulty. The error can then be corrected during ongoing operation and the monitor system can be restarted (e.g. by means of /SHUTDOWN and Restart).

If no parameter set for VM2000 is entered in the startup parameter file, the default values are used for the VM2000 parameters (see "Setting the VM2000 parameters in the parameter service").

Startup checks whether a version specified in the parameter file matches the loaded version of the VM2000 monitor (VM2-MON subsystem) and the VM2000 hypervisor (SU /390).

The attributes and resources of the monitor VM were set when VM2000 was installed, see chapter "Installing VM2000".

Regardless of what is specified for the monitor system in the PROCESSOR operand, all of the real (normal) CPUs that are ready for operation are started at startup of VM2000. The hot spare CPUs and extra CPUs are also made ready for operation.

System initialization for the monitor system is terminated with the messages:

VMS5541 *** VIRTUAL MACHINE SYSTEM VM2000 V12.0B READY ***

NSI0000 *** S Y S T E M   R E A D Y ***

If VM2000 on SU /390 can work with VM definitions, after BCAM ACTIVE the following message is displayed: VMS2330 STORAGE FOR VM DEFINITIONS ACCESSIBLE

Dialog startup

In the case of a dialog startup, after the corrections for the operating system have been requested, entries are requested on SU /390 for the VM2000 hypervisor and the monitor VM.

On SU x86, the attributes and resources for the monitor VM are set via the SE manager, see section "Configuration using the SE Manager (SU x86)". No further specifications can be made for VM2000 when startup takes place.

The entries can either be contained in the configuration file or be input directly at the BS2000 console. After the entries for VM2000, the dialog startup procedure is continued in the same way as for native operation.

 

The steps of the dialog startup procedure relevant for VM2000 are outlined below:

The operator is requested to enter the file name of the VM2000 hypervisor file:

VMS5005 ENTER VM2000 HYPERVISOR FILE NAME.
        REPLY(<FILE NAME>; EOT(USE STANDARD FILE))

The following responses are possible:

P.	A VM2000 hypervisor file which is cataloged in the parameter file or with the standard file name SYSPRG.VM2000-HPV.<ver> is loaded.
P.<filename>	A VM2000 hypervisor file which is created as a PAM file with the name <filename> is loaded (see "Installing the VM2000 hypervisor files (SU /390)").

The operator is requested to enter the file name of the VM2000 hypervisor REP file:

NSI0050 SPECIFY VM2000 HYPERVISOR REP FILE OR DEVICE.
        REPLY ( EOT (USE STANDARD FILE);FN=FILENAME,(VOL=VSN);CONS;END )

The following responses are possible:

P.	The standard VM2000 hypervisor REP file entered in the parameter file or cataloged with the standard file name SYSREP.VM2000-HPV.<ver> is processed (see "Installing the VM2000 hypervisor files (SU /390)").
P.FN=<filename>	A VM2000 hypervisor REP file created as a SAM file with the file name <filename> is processed.
P.CONS	Direct entry of REPs at the BS2000 console. The dialog is the same as when entering REPs in native operation.
P.END	Entry of the REPs is terminated. Startup continues.

More than one file can be processed. Additional REPs can be entered at the BS2000 console.

   

The operator is requested to input the file name of the configuration file for the monitor system or to input VM2000 commands at the BS2000 console:

VMS5027 SPECIFY VM2000 CONFIGURATION FILE NAME. 
        REPLY (EOT(USE STANDARD FILE); FN=<FILE NAME>(,VOL=<VSN>); 
        CONS(CONSOLE CMD INPUT); END(END OF INPUT)) 

The following responses are possible:

P.	A configuration file of the monitor VM entered in the parameter file or cataloged with the standard file name SYSPAR.VM2000-MON.<ver> is processed.
P.FN=<filename>	The configuration file <filename> is processed.
P.CONS	Direct input of VM2000 commands at the BS2000 console. The VM2000 commands are requested with the message: VMS5021 ISSUE VM2000 COMMAND (MAX. 70 CHARACTERS) OR 'END' (EOT=END). REPLY (DESIRED INPUT) One or more VM2000 commands /CREATE-VM and /ADD-VM-DEVICES can then be specified for the monitor VM ("Configuration via the VM2000 configuration file (SU /390)"). The maximum permissible input length is 70 characters (without P.). P. terminates the input of the VM2000 commands from the BS2000 console.
P.END	Input for VM2000 is terminated. Startup continues.

• The message VMS5027 is repeated until the response P.END is received. Several configuration files can be processed. The last /CREATE-VM correctly entered overwrites the previous /CREATE-VM.

• If P.END is entered immediately in response to message VMS5027, the default values are assumed for the attributes of the monitor VM (see "Configuration via the VM2000 configuration file (SU /390)").

• Errors in the configuration file commands are reported at the BS2000 console. File processing continues.
