Or you may consider assign the data sets a specific MGMTCLAS (based on the PGM), which then can be specified. Be sure CA 1 SMS option is set to EXT, so that the true MGMTCLAS from allocation is retrieved.
The hlq.CTAPOPTN(TMOOPTxx) SMS parameter has the following options:
-YES = Enables CA 1 Tape Management System to record and use an SMS Management Class that the SMS ACS routines assigned.
-EXT = CA 1 Tape Management System obtains the true SMS Management Class during open-for-output processing. If the device is SMS-managed, then CA 1 Tape Management System records and uses the SMS Management Class that the SMS ACS routines assigned. If the device is not SMS-managed and no SMS Management Class is assigned during allocation, CA 1 Tape Management System drives its own call to obtain an SMS Management Class.
-NO = (Default) Disables the option.
