The thing I would be concerned about, is changing the order of the CPOWNED volumes.
In this case, you are not. But, is there some requirement of keeping the spool volumes in the same order? In other words, if PACK03 will now contain spool files, what would happen if the cpowned list shows: PACK01, PACK02, PACK03, PACK04, PACK05. But your spool files were on: PACK02, PACK04, PACK05. Would inserting the spool volume happen at the end of the spool list? In middle of the spool list? Or who cares? And which would end up cold starting the spool areas? I think you have a right to be concerned. I would offload my spool before doing such a thing. But I have good access to tape.

The 5.3 install allowed me to format page and spool as 3390 mod 9 devices (10017 cylinders). But in fact, I was using 3390 mod 27 disks (32760 cylinders). If I go into the devices with ICKDSF and change the remaining cylinders to PAGE and SPOL, I¹m fairly sure nothing bad will happen to the page volume, but will the spool volume remain intact? Or will I be cold-starting and rebuilding my SDF files? Do I need to back everything up (requiring tape, which is scarce here), or can I get away with just doing it? -- .~. Robert P.
