RE: hardware issues after voltage regulator replacement Power 7

This code indicates that a Power Hit has occurred. The machine does a mini IPL to code 110000AC (stand by code). To continue the IPL, verify that the green light is slowly flashing. If it is, press the white button and verify that the SRC Codes are changing. If SRC code 110000AC displays again, there are hardware problems and the user must contact Hardware support.

Subject: hardware issues after voltage regulator replacement Power 7

I'd like to understand whats going on.
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... ?
