Re: hardware issues after voltage regulator replacement Power 7

As Chris mentioned the 110000AC means AC Power failure not that a part failed. It's possible that a part has failed but likely not the VRM as that calls out rather clearly and without it the system will not come up.
The 8150 errors are calling out the RAID card or cards. What I have seen is that the cache index memory is bad - fatal for the card. Many RAID cards in POWER7 don't have batteries including the 57b5, so nothing there.
Another possibility is the two cards are not communicating via the SAS cable between them.

Problems after power voltage regulator replacement.
Not under ibm maintenance-but that is not what this question about (this
system to be decommissioned shortly).
8202-E4D System dropped hard with no warning.
system in a "server room" with large room UPS - other servers showed no
issues
Via hmc, 3rd party maint saw voltage regulator part 110000AC as top issue
in HMC, and was replaced.
System came up - very long recovery
Now 4 issues in SST Activity Log
57B58150 Raid Cache Card - Class = Perm
110000AC still shows (but machine did come up - Class = Perm
57B59076 Raid Card - Class = Perm - has same location as 1st 57B5
B600-5090 19A1 (one) internal drive - Class = Qual

When run the SST option to display cache battery issues - nothing in the
list
WRKDSKSTS shows all 31 drives in degraded status, but last 2 have diff %
Used

Questions:
What is the meaning of SST Activity Log Class=Qual for disk drive ?

Guessing Raid Controller card not working is reason no batteries in list?

After voltage regulator card replacement, but activity log still shows as
Perm issue, but machine did come up... ?
