Pat ran into this problem when applying PTFs. He writes, "We are running V5R2. When applying the CUMs, I always do the HIPER and DATABASE PTFs before I do the CUM. I IPL between the two groups. During my last two CUM applies, I got false hardware errors that halted the IPL. The first time I got the code that indicated there was a bad disk controller. There was not.
"The second time I got the code that indicated two disk drives wer missing. They were not. Both times I was able to manually IPL from the B side, then re-IPL unattended from the B side and everything was fine.
"Both times I called IBM and was told the the 'microcode must have gotten confused.' With the next CUM being released next week, I really don't want to have it happen again. Coincedence or actual problem?"
What do you think?
