Re: hardware issues after voltage regulator replacement Power 7

["Larry \"DrFranken\" Bolhuis" <midrange@xxxxxxxxxxxx>]

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.
