Thanks to all that have responded - we're back and running again, but not due to any work on my part.
My description of the failed system was not complete, for fear of confusing the issue - it is a guest z/OS under z/VM that is supplied by a.n. other party. I contacted them and the bad IEFUSI was renamed by a techie at their end. Rob: thanks for the referral to cbttape. I wasn't aware of that particular file there. I'll take a closer look later. I've had the comfort of a recovery system in the past. Sadly, that wasn't an option for me in this case. Peter: "...[54m value] has no meaning and will later be replaced..." Yes - Overnight I began to understand that. No matter what I've done so far, that SMF30RGN value continues to report '54M'. I 'new' thought for me in the course of this work is that SMF30RGN is the REGION size that was _requested_ (as per the documentation). It is not the size actually _given_ after IEFUSI/SMF/JES, etc have finished their meddling. As far as I make out, there is no such 'after the fact' value logged in any part of the type30 record (or any other). Which basically means that all this work has been a waste of time, based on a misconception. Peter again: [paging space related to the problem]... sorry - my poor description there. The alternate SYS1.IPLPARM(LOADxx) member leads to an incomplete definition that does not specify any paging space, so it won't IPL. Carmen and Peter: I simply did not think about the possibilities of SETPROG EXIT..., My mind was chasing itself in circles at the time. And then the supplier's technician fixed things up. I must re-visit my failed 'back-out' LOADPARM member and make sure it brings up a minimal system - possibly with whatever I find on the cbttape. And abandon this line of effort - I'm pretty certain that SMF30RGN point above is correct. Unfortunately, that leaves the cause of the original IEW4000I and CSV031I messages unsolved. I will have to think of a different way to attack the problem.
