Not necessarily.

There are certainly times when ACS routines need to allow a data set to be 
placed on a non-sms volume, but that usually shouldn't be triggered just by 
the specification of a UNIT or VOLUME parameter.  Remember that SMS was 
intended to work without ordinary users having to change their JCL.  As a 
result, it is not uncommon for old JCL to still have UNIT and VOLUME 
information in them.  SMS assigns the data regardless.

Many shops have a pseudo storage class, such as "NONSMS" that is used to 
tell SMS that the data set is not to be managed.
