Just ALLOCATE. Format would have been more devastating. Regards, Richard Schuh

Kris, IBM Belgium, VM customer support "Schuh, Richard" <[EMAIL PROTECTED]> Sent by: The IBM z/VM Operating System <IBMVM@LISTSERV.UARK.EDU> 2006-10-30 21:32 Please respond to The IBM z/VM Operating System <IBMVM@LISTSERV.UARK.EDU> To IBMVM@LISTSERV.UARK.EDU cc Subject Corrupted IPL Record If this shows up twice, I apologize. I first sent it 2 hours ago and it hasn't hit the archives as yet. Over the weekend, we upgraded our final system to 5.2. As a part of the migration, we changed old PARM extents to PERM and allocated new PARM extents. When we tried to ipl the system, there were errors that led me to the conclusion that the IPL program had been corrupted. Using DDR on another system, I observed that record 0 0 2 had been completely wiped out. There were a few scattered bits that were not 0 in the first 100-200 bytes, nothing that was any kind of pattern, and the rest of the record was all 0. Records 1, and 3-6 were all as they should have been. I had to run SALIPL to fix the IPL program. I am not blaming CPFMTXA ALLOCATE because I think it highly unlikely that it was the cause. I suspect that something else happened between the previous IPL and yesterday's failed attempt. Has anyone else seen this kind of corruption or are we, once again, unique? Regards, Richard Schuh
