Right. And coming to this late... SMF 78-2 has all the numbers you'd usually need on this. My standard reporting generates useful stuff on this - but generally I don't bore my customers with it. If it's exciting, however, ... :-)
Quite often I see SQA oversized leaving unusable 24- or 31-bit SQA. (Also oversized CSA, but that's a different matter.)

Actually, it's the other way around, as I think of it. CSA can be converted into SQA. If a request to obtain storage from SQA cannot find it from the defined SQA, the system may convert CSA to satisfy the request. It will not do the reverse. This is why some customers will underconfigure SQA and overconfigure CSA.
