Rename SVTS and SVTSAS PROCs

In an environment where multiple CA Vtape Subsystems are active on the same LPAR, multiple PROCs with unique names can make it easier for the operations and technical support personnel to monitor and manage CA Vtape. To support this environment, you can rename the SVTSCE PROC.

If you want to rename either of these PROCS, then observe the following cautions:

• You cannot rename the PROC to a CA Vtape Subsystem-ID (SVTn where n = 1-8). This can cause the tasks to start under the MASTER subsystem instead of JES, resulting in JCL errors or other problems.
• If you rename SVTSAS PROC, set the SubaddressSpaceName attribute to &JOBNAME. The attribute is in the Startup Options Section of the OSPARMS Parmlib member.

If you rename or create multiple PROC sets, a pattern (SVTSCE1, SVTSCE2, SVTSCE3, and so on) allows for identification of the Subsystem and its sub address spaces. In these PROCs, the SVTS parameter is set to the corresponding subsystem-ID (SVTS=SVT1, SVTS=SVT2, and so on).

The last digit of the subsystem-ID in the PROC name reinforces the need to use the proper console command prefix or SVTS parm value when issuing commands or running reports to investige a particular subsystem. When investigating the SVTSCE2 tasks, issue console commands with a command prefix of SVT2 and use a parm of SVTS=SVT2 for utility jobs.

When starting or stopping the renamed PROCs, S/P SVTSCEn, where n is the last digit of the appropriate subsystem-ID would suffice. When restarting a Virtual Tape Controller address space, the command prefix would control the restart. SVT1 R CU=1 would restart SVTSCE1.SVT1V1, the Virtual Control Unit address space one for the SVT1 Subsystem.

Continuing with the example, the sub address spaces uses the same PROC as the main address space. If the PROC name is SVTSCE1 and two Virtual Control Unit address spaces that the main task starts, you see three started tasks executing on your system with job names of SVTSCE1. The main task has a step name of SVTS or SVT1. The controllers have step names of SVT1V1 and SVT1V2.

If you prefer that the sub address spaces use a different PROC name, you can copy the SVTSCE1 PROC to a new member (SVTSCE1A, for example). You then set the SubaddressSpaceName attribute in the Startup Options Section of the OSPARMS Parmlib member to a value of SVTSCE1A. When SVTSCE1 is started after the change, the main task is still SVTSCE1 with a step name of SVTS or SVT1. It starts the sub address spaces with the SVTSCE1A PROC so that the two sub address spaces have job names of SVTSCE1A with step names of SVT1V1 and SVT1V2.
