SolutionYou need to replace only the battries. If the cache module is installed, then there will be 2 battries. One on the controller board and one on the cache module. Both the battries are replaceable. Spare part no: 307132-001.
If the server or the controller card is in warranty log a call with HP Support.
Else, buy the spare part. Turn off the server, remove the 641 controller card from the server and then remove the battries.
There will be a metal strip holding the battery to remove the metal strip, at the back of the battery there will be 2-3 latches to release the metal strip. Once the strip is removed, replace it with new one.
Hope this helps.
Regards,
Raj.

Re: Array Accelerator battery failure
I do agree that first step is to upgrade the firmware to the latest version.
HP Smart Array 641 Controller Overview:
http://h18000.www1.hp.com/products/quickspecs/12067_na/12067_na.HTML
This controller has 64MB BBWC (Battery-Backed Write Cache) by default and has an option of upgrading to additional 128-MB BBWC (Battery-Backed Write Cache) making a total of 192-MB. If optional 128MB cache is used then it will have its own Battery.
You could see it in the image behind the 128-MB add-on chip.
Regards,
Raj.

Re: Array Accelerator battery failure
Modular, easy-to-upgrade design lets you optimize performance as needed with the 64MB and 128MB BBWC Enabler, from 64-MB of memory for RAID and read cache to up to 128-MB of BBWC.
The 64MB BBWC Enabler + 64 onboard makes 128MB BBWC
The 128MB BBWC Enabler + 64 onboard makes 196MB BBWC
so for all memory that stay's on board it act only as READ and added meory 64 or 128 act for BBWC as READ/WRITE
as you notice it say's ENABLER, otherwise it would be called Upgrade only.
There is no BBWC for 64MB onboard memory; it comes only with 64 or 128MB BBWC

The 128MB BBWC Enabler + 64 onboard makes 196MB BBWC ? No
So for all memory that stay's on board it act only as READ !
And added memory 64 or 128 act for BBWC as READ/WRITE!
