The method depends upon under which operating system you are running.  I note
that DBSTU1 runs VM/XA SP 2.1.  The preferred way under VM/XA is to use
Diagnose X'210'.  However, if your program has to be compatible with releases
of VM/SP with or without HPO, you can use Diagnose X'24'.  The specifications
of how to code these instructions can be found in the CP Programming Services
manual.  In either case, the values of fields VDEVTYPC, VDEVTYPE, RDEVTYPC,
and RDEVTYPE returned by the Diagnose are what you are looking for.
