Re: 571B-001 Storage Controller battery cache

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

If that RAID card is the integrated one, and you pull it to change the 
battery while there is power to the system, you will most likely wind up 
replacing the backplane and all the cards in the CEC. Don't do it. Power 
off to change it.

I don't remember seeing the type/location of the RAID card in the OP, so 
best advise, power it off, give it 5 minutes, then pull the card to 
change the battery.

I had a customer ignore that advise and 4 days and about $15K worth of 
parts later, the system was back up and running. The $15K did not 
include IBMs time to help nor mine.
