Re: 571B-001 Storage Controller battery cache

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.

It actually WARNs you that powering off your system to replace your cache
battery pack WITHOUT failing the card first may lose data. So, powering
off your system, even controlled, is not the answer some think it to be.

Of course, where the blazes are the steps they talk about on that page.

Is this true?
