Replacing RAM on an HP Smart Array P800 controller cache module.

Hello Everyone,

I have an HP Proliant DL185 G5 storage server with some trouble on the Array Controller. It is a Smart Array P800 controller with a battery backed 512mb Cache module.

When I open up the array configuration utility (ACU) i get the following error message:

"An unrecoverable ECC error occured when trying to read data from the array accelerators's memory. Array accelerator operations are permanently disabled."

My question is then, is it possible to simply replace the RAM block on the Array Accelerator and what sort of RAM would I then have to replace it with?

Thanks

/L

HP's website is playing tricks again and can't get at the DL180 maintenance service guide, however same controller used on Integrity so removal proceedure can be found here -  http://h20000.www2.hp.com/bc/docs/support/SupportManual/c01609699/c01609699.pdf

Don't have the spare part number of the cache module though, and anyway isn't it still under 3 years warranty?

Well I know how to replace the whole cache module, but seeing as I do not have one of those I was inquiring as to if it was possible to replace on the RAM on it?

If you have a surface-mount rework station then yes, you can replace individual RAM chips, if not you have to replace the whole module.

As our company couldn't find any reference to the BBCM anywhere, or how to order it, we ended up purchasing a new P800 controller. We will experiment on the broken one and see if we can make it work in a spare server.
