In addition to influencing a data set’s storage class with the copy command, you can also give ACS input for assigning or overriding the data set’s management class. By specifying MGMTCLAS, you can pass a management class name to ACS and, as with STORCLAS, ACS ignores it, assigns it to the data set, or uses it in combination with other things to determine the data set’s management class. By specifying NULLMGMTCLAS, you can pass null management class to ACS, which might or might not assign a management class to the data set.

Also, just as with STORCLAS, you can use MGMTCLAS with BYPASSACS to ensure that the data set is assigned the management class you specify. Ensure that the management class you specify with MGMTCLAS is valid, or you will get an error. You must be authorized to use BYPASSACS and the management class you specify with MGMTCLAS.
