keep in mind that a MGMTCLAS is involved, which if sms may or may not allow UNIT=DISK when DD DUMMY is used.
not completely <actually at all> understanding sms and it's effect
has caused me untold grief when I would play with the UNIT parm,
normally UNIT=SYSDA gave me a pass; but at other sites UNIT=DISK was ok.
Problem with sms when you override a DD with DUMMY, is that you have to insure that all the rest of the DD parms conform to sms requirements,
or you get a JCL error.
my guess is that since sms is site configurateble (is that a word),
going from site to site means trial-and-error, or learning SMS.
unfortunately, I am a trial-and-error type guy.

Dick, if SMS is implemented correctly, then what ever you specify should not cause any errors at all. There will be times when it may cause you some minor irritations for which you need to visit your friendly storage gurus for allowing you to do what you want rather than what we want.
Whenever I set up an SMS environment, the user has absolutely no need to even know about DATACLAS, STORCLAS or MGMTCLAS, let alone code them. Almost everything is overridable by the user with some notable exceptions like retention periods.
