Along those lines, I saw it mentioned that the guests were changed from
V=R & V=F to all V=V.
Did this coincide with the problem ? Might this change have increased
paging enough to expose an improperly formatted area that had not been
previously used?

Have you also checked your spool areas? One can overflow into another if
your page areas are full, and if all you use the VM system for is to
support guests, you may have reached the point where you need more space
than you have. I've also seen this error when a paging area was
incompletely formatted (off by 1 error on my part).

Subject: Re: z/VM paging problem
Hello David and everyone else,
Thanks for all the info.
The root is that everytime I IPL any CUU I am getting the
HCPCLS174E Paging I/O error; IPL failed.
IPL 190 fails but IPL CMS works ok
All our current systems are VSE systems and they IPL 740.
My VSE261 tech machine is failing when IPLing from 740.
Any IPL of the tape drives are failing (Standalone tapes)
I am attempting to understand what happened to the paging areas
that would cause this problem.
I do not have overlaps, the volumes (430RES and 430W03) have not been
formatted for a long time.
Two weeks ago, everything was working fine.
I am getting a new page disk formatted and I intend to IPL on
Thursday at 11:00 pm.
I am worried that there is something else that I am missing.
