Overriding attributes defined in the storage class

You can specify volume serial numbers on the VOLUME parameter if the storage administrator has specified GUARANTEED_SPACE=YES in the storage class for the data set.

For example:

  
   //SMSDS4  DD  DSNAME=MYDS4.PGM,STORCLAS=SCLAS04,DISP=(NEW,KEEP),  
   //          VOLUME=SER=(222333,333444)

In the example, the data set will reside on volume serials 222333 and 333444.
