Title: RE: z/VM paging problem

Could someone have defined a minidisk overlapping the paging area, formatted it, realized they made a mistake, and removed it without you knowing? Alternatively, what userids, if any, have write access to these volumes? Could they have accessed one of these disks and written something to it? If you have DITTO on VM, you could link the disks read-only, and do a disk record scan on the paging area, looking for anything odd. Once you found what and where, figuring out how and why could be easy.   -----Original Message----- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Edward M.

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.
