Hi Sire,
IS quite challenging as I have followed on the Centos OS solution but I dont find this file /etc/sysconfig/lm_sensors too. I am practically lost and have no idea what to do next as the disable also not working either.

Hi,

How about the "ipmi" service in section "workaround" from "Potential cause #1", does it work?

In case the ipmi service is not there, What does the "dmesg" command output?
#dmesg > /root/dmesg.txt

Good Luck

Hi Sire,
How mean service ipmi stop no even this does not work either too. It gives me ipmi:unrecognized service. I have attached dmesg.txt file too.

Hi,

Looking at your dmesg file, I found that the server is a Cisco UCS C200 M2 (right?)

Then, searching the forums for cisco support i've found this:
Problem with sensor that is corrected with a Bios upgrade
https://supportforums.cisco.com/message/3530456#3530456

I'll let you know if I find anything else.

Good Luck,

Hi Sire,
Yes you are right we are using Cicso UCS C200 M2. IF we upgrade the bios or firmware I am not too sure will these effect the warranty of the servers what is your opinion on this?

siremaxus 05-13-2013 01:31 PM

Hello,

If your servers are still under warranty you can open a support case with cisco and ask them if the bios update would solve the issue you are having right now.
Take advantage of your support contract, that may lead to a hardware change if they detect that there is some faulty hardware.
Usually support ask you to update bios, CIMC, firmware, etc. and test if that solves any of the issues you have, if not, then they begin to dig deeper.
For every update or upgrade you can ask cisco support the procedure according to best practices.

Good Luck

Hi Sire,
Definitely I will now focus on that but incase you find any clue from Linux do let me know so I can test them too. Thank you.

Get rid of kipmi0 (CentOS 6.4)
 
Hi! For some reason I also wanted to get rid of kipmi0 on my CentOS 6.4 x64 installation. It was built in the kernel. Thus I edited kernel .config and replaced all *_IPMI*=y entries by =m. Rebuild the kernel and reboot. No more kipmi0.
Good luck!

Dear Pethruha,
How do you rebuild the kernel ? What is the =m stands for ?

Petruha69 10-08-2013 03:47 AM

Dear newbie14,
I summed up what I did on http://myelectrons.com/build-linux-kernel-centos/
I'd be glad if you let me know whether it was helpful or otherwise.
Cheers,
- Serge.
