Ensuring common storage tracking

To ensure that the Common Storage report (STORC) provides complete data, it is required that VSM common storage tracking is active. This can be achieved by issuing the command:

SET DIAG=01

The defaults in the parmlib member DIAG01 are:

VSM TRACK CSA(ON) SQA(ON)

If VSM common storage tracking is not active, one of the messages ERB617I, ERB618I, or ERB619I will indicate that the report can be incomplete for some jobs.
