You should only the amount of storage that you need to be able to dynamically configure offline while MVS is running. If you do not need to be able to configure any storage offline dynamically, you should specify RSU=0. The amount you have specified is 32 times the storage increment size (which depends on the machine model and storage configuration). I recommend using RSU=xxxxM or RSU=xxxxG so that your specification is not dependent on the storage increment size. Jim Mulder z/OS System Test IBM Corp.
