IBM error code 2807

ibm error code 2807

Found error 2807 on your RAID card IBM server?

As you can see on the picture i got "error 2807" or "IBM Serveraid 7K onboard not responding properly error code 2807" on our application server (IBM series). This error related to RAID card which can not read it's logical RAID configuration. This means that the server can not boot and it's a big, big problem to us. We tried to fix this error as there is no maintenance contract for this machine. I googling to see whether someone experience this problem also.

There are about 73,400 result on this error problem. So i am not alone here. IBM suggesting to upgrade BIOS version to the latest version 7.12 ( actually we already version 7.12 ). So this is not apply to our problem.

While we rebuild another server to replace this machine and restore all the data from our last night backup we also pull out this server from cabinet and try to open the case the see what happened inside. At first we found nothing strange with the hardware, but when we open further more, we see that the battery of RAID memory card is swollen and bent the RAID memory. We try to clean up the hardware and re-insert the RAID memory and battery. We still have the problem and we feel that the chances is thin to fix the problem by our self.

swollen battery

Horay...we fix it finally

We try to separate the battery from RAID memory to fullfil our curiosity... we reboot the server and bingo! now the error code has gone and everything seems to be fine.
We are finally sure that the problem has gone completely after doing several times reboot, shutdown and restart.
It seems the problem come when RAID card memory was bent because of swollen battery push it severely.

@chin: You did the best. In my case the server already out of warranty and will take times to order new RAID card. So i have to find the quickest solution and came up with that.

Tanks for the Info

When i open the chasis i saw the battery i think "that's cheap", and yes it end being cheap... Fix my trouble ez, just put the battery outside its metal case and secure it with tape. I guess it will work a couple of years more.

Unfortunately my problem is not solved. I was reinstalling Win2003 and during the format process I got an error. Now I can't get it to work anymore. I'm getting error 0000 and sometimes 2500. I guess I will have to order a replacement card hoping this solved it for good If not then something else is wrong..... :/

Same problem here. Solved by separating the battery from the controler.!!! The raid-controler is working now but there is a permanent micro-bend :-))

Thanks a lot for the fix. Shame to IBM for the fault controler design.

quick question experts.. By removing battery, Do I loose RAID Configuration? If am following it correct, I should remove the Battery from RAID controller and switch on the server. Would I be able to bring up the server after removing battery?

Request an immediate response..One of my server is down.

You should separate the battery but still connecting it with RAID memory/card. In my case, i extend the cable.

Good luck.

Hi All,

I have the same problem on my IBM x346. Error msg 2807 on boot up. I've released the battery from the raid card memory, but my server still does not boot. Has anyone had to replace the Raid card memory and battery due the bending of the chip?

Any comments when go down a storm!

Swollen battery had bent the RAID card, worked fine after the battery was separated.

Thanks for your post!

Wesley Konrad 4 years ago

Had the same problem. As of right now, we have removed the battery and it seems to operating fine. Are there any long term issues with running without the battery?

Rob 4 years ago

Had the same problem, which this did fix. Had to bend the card back into shape first though. But after the second attempt it worked. Also read this off the IBM site, which makes me think we should be operating these servers without the battery:

"Once the battery has reached its 18th month cycle of usage, it has been determined that the battery may no longer maintain the expected charge capacity. In addition, the IBM ServeRAID 7k controller does not have the capability of providing real time statistical data from the battery that is viewable in the ServeRAID 7k support log files. Our current IBM ServeRAID products, such as the ServeRAID 8x-10x series controllers, do have this real time battery data capability. As a result, IBM is recommending that all users replace the battery every 18-24 months, or remove it to run in Write-Through mode. This avoids potential problems and ensures that data is maintained in the event of a power outage."

Dmitry Irtegov 4 years ago

Happened to my server too. IBM suggests power cycling as workaround, we tried that and tried to reload configuration from disks. It failed, we found your post and I decided to look inside.

Battery looks exactly like yours:

It booted when we detached the battery, but I guess we need to replace the battery and probably the DIMM.

Dmitry Irtegov 4 years ago

- Are there any long term issues with running without the battery?

You risk of losing your data after powerdown or even simple unclean shutdown. Not just chrdsk/fsck run, but utter destruction of filesystem. It goes like this: power goes off, RAID manages to write data but not checksum. With battery, RAID remembers to write checksum after powerup. Without battery, RAID sees checksum mismatch and tries to fix it, and with 50% probability gets garbage instead of data. Worst case scenario when this garbage happens to be filesystem log. OS boots up, tries to redo the filesystem log and writes garbage all over it's own metadata.

At least, you should turn off write back cashing in your RAID configuration, this kills performance but makes worst case scenario impossible.

@Dmitry Irtegov

I never recommend to remove battery, if possible replace with new battery or... make the battery cable longer so you can put battery somewhere around the RAID card. On my case i bound it to casing using tapes.

Dmitry Irtegov 4 years ago

Does battery in this condition actually work as a battery? And are you sure it won't leak something to motherboard?

I thought about replacing it with some kind of cell phone battery of similar capacity (our server is long out of warranty and getting genuine spare parts is lengthy process).

It still have some voltage there, yeah it may will leak sometime :-)

We had a server die this morning with the same error message, so I checked this and sure enough when we detached the battery and rebooted the server it came back up again. We checked two other identical servers, both of which had swollen batteries, so we fixed those as well.

Lifesaver. This just worked this morning for us on our primary backup server. X346. Battery was so swollen almost coulnd't get the Raid car out..

Thanks a million!

chipdip 3 years ago

well played sir. I found the swollen battery but didnt think it was safe to run and didnt think of separating my battery from the card.

Main SQL server and financials server is now up and running while we await a new battery.

thanks Free Stuff!

Rick 3 years ago

Wow, I am so glad I found this solution. This fix solved our problem, the same as you described. The battery was so swollen that it was difficult to remove the SCSI controller from the edge connector. Once removed and the battery separated from the daughter card and the aluminum cover removed all is well. Our server booted - what a relief.

By the way, IBM quoted me $1964.00, as a starting point, to dispatch a technician to investigate this down server. This server is out of warranty with no maintenance so the quoted price was crazy high.

Thank you for posting your tip two years ago! It helped me today - July 23, 2013.
