Array Accelerator battery failure

Georgia Bryant — Fri, 08 Dec 2006 09:54:30 GMT

I have a message that the batteries on the Smart Array 641 Controller have failed. Cane they be replaced or do I have to replace the entire board? If they can be replaced, how do I go about it?

please be sure to upgrade at least to Firmware Version 2.48 (latest 2.68)

This Version includes a fix with several battery charge issue

when this doesn't fix the issue, exchange the cache battery

cheers

Hi Georgia,

You 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.

Raj 641 use only one battery

Hi Oleg,

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.

so what we missing when we reading?

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 64MB BBWC Enabler + 64 onboard makes 128MB BBWC ? No

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!
