Robert, Did you get any messages in the IDCAMS output like: IDC0181I STORAGECLASS USED IS ABCDEF IDC0181I MANAGEMENTCLASS USED IS ABCDEF IDC0181I DATACLASS USED IS ABCDEF
You can also try adding to the cluster definition: VOLUMES(*) - I doubt that it will help because the real problem is that the SMS ACS routines are not assigning a storage class to the vsam dataset. Are the SMS ACS routines your responsibility?
