Display the ISMF storage class definition of the storage class assigned by the ACS routines. If INITIAL ACCESS RESPONSE SECONDS is zero, then the object is stored on DASD. If a nonzero value is specified, and SUSTAINED DATA RATE is greater than or equal to 3, then the object is stored on tape. Otherwise, the object is stored on optical media. If the media assigned by the storage class is unexpected, correct the storage class definition. If the wrong storage class is being assigned, correct the ACS routine. In either case, validate and activate the new configuration.
