False CPU Overheat on DL380 G5

[Steve Evernham]

We've been fighting 2 servers with the same issue. We've updated the firmware to the latest (BIOS 2008.01.24 (30 Jan 2008))and greatest as well as the PSPs. We've replaced the CPU fans and the fan board. Still no luck ... CPU's show at 255 C. Any ideas?

[KarloChacon]

hi

first of all
where are you getting those numbers? temperature values?

second of all
any amber - red light?
are servers up and running?


-----------
try this
1. clear NVRAM
2. remove power cable for 1 minute.
3. and also reseat riser cage.

hi,

have the procs being removed? it may be the thermal grease or thermal tape between the processor and the heatsink that dried out, does no have any of is not sufficient

I"m seeing this same problem on one of my servers....

I'm seeing the same numbers on HP Sys Mgmnt Homepage CPU @ 255deg C

[KarimK]

I have the same issues here, all CPU temptretures are reporting 255 C..

Did anyone have any luck sorting this out?

[KarloChacon]

update to proliant support pack 8.2 and firmware CD 8.2

that's either a system rom issue or HP agents issue reporting incorrect information

[B J Singh]

Karlo;

Have you tested 8.2 PSP and Firmware for this specific issue?....

I know my servers have 8.1 and I still have the problem.

[KarloChacon]

hi


it's part of the troubleshooting process if you call HP...

since it's false message we have to check if it is a bug in the System ROM or hp agents

Steven,
I have another question for you, regarding the load balancing wire on you're P-Class enclosures, I've read your reply on that issue, is it still an issue for you? for me it is now and I would like to know how it was solved o you're site.

Regards,
Aad

Hello,

It appears this post has been inactive for a time but anyway I´d like to know if there was s resolution on it.

The thing is that I´ve been working with a CU for over 2 weeks now and he has the exact same behavior described at the beginning(255° C on CPU´s sensors). the server is up and running and we´ve applied the latest PSP and FW CD on it with no changes. The IML shows nothing related to temperature and server have not been shutted down due to the same.

Right now I´ve asked the CU to reseat some HW components as well as crearing the NVRAM to see if that makes a difference.

Any suggestions?
Thanks

[Bijl]

Not the best answer but it has worked for me:
1. Thermo paste, it makes a world of difference
2. I once did a rollback on the Bios and it fixed the issue.

Regards,

[KarloChacon]

I can tell you that that is a false message it won't affect performance or it won't cause any damage

If I am not wrong (I can double check tomorrow) HP is going to release a new driver for ilo which will fix that CPU high temperature

bye

I have seen the 255C on multiple DL380G5's. Our first fix recently was to replace the system board, but don't want to do that for all. Is there an Advisory issued by HP on this?

[Geovanny Vargas]

Alright guys, I certainly appreciate the fast response... I would say the thermal paste should be an option in case the server indeed is having the high temp but in this case it appears to be false information.

I hope the ILO driver is released so we can have that fixed using it instead of having the MB replaced... :)

[Geovanny Vargas]

Karlo, you were right.
The solution will come in the way of an updated il02 driver, available in the 8.2 PSP available in mid march :(

Once installed the expected behavior is that the server will no longer be degraded in the SMH as a result of inaccurate temperature data being reported to the agents

I guess we are gonna have to wait...

Thanks again

[Doug McBrain]

Any resolution to this issue, as we are now having the same CPU 255C overheat message, yet not error light on front panel.

[KarloChacon]

did you read above PSP 8.2 will be the solution...

[Doug McBrain]

So...the updated psp is definitely going to be the fix?

[B J Singh]

Karlo, can you point to a CA(Customer Advisory) that discusses this specific fix?
When you do respond, try to be a bit more understanding of the customer's situtation. No one needs to be treated like children when looking for answers from HP for problems they're having with HP's products.
Professionalism and courtesy is always appreciated!

[KarloChacon]

customer needs to call HP and request for that document it is bot a public document that's why

basically they are gonna say the say as I did

[KarloChacon]

I meant it is not public

God I've love an edit option after replying

[Emir Prcic]

Any news? Where can I get the service pack?
My productive server is showing the same problems.

3 CPU 255 C 127 C Caution
4 CPU 255 C 127 C Caution
5 Power Supply 55 C 77 C Caution
6 CPU 255 C 127 C Caution
7 CPU 255 C 127 C Caution

Hi all,
I have installed the PSP 8.20 and my CPUs have still 255°C :(
What now?
Thanks for any helpful info

[Christoph Z.]

Hi,
I've had the same issue. Support told me that PSP8.20 would be the soultion but as I opened the case in November I did not want to wait. Last week I got a new system board and the error message disappeared.
I am surprised that PSP 8.20 is not the solution, as 2nd level said. This would mean, that a former update crashed the sensors...
It was hard discussion with the support but finally I got a solution.

Hi Chris,

We have the same problem for months, HP did
same cr.p with us "wait for 8.2" it fixes everything, and it didn't.
What was your final solution ?
Thanks
