HP Proliant ML370 G6 fan problem

[Eelco Meijer]

Hi,

The ML370 server at one of our customers is acting up lately. It speeds up the fans and then tunes them down again. It's not hot in the neighbourhood of the server, so that shouldn't be the problem.

Also once in a while it gives notice that the system will shut down cause of fan failure.

These are the some notices from the IML:

Hi, tried those thing already, no success unfortunately.

BUT, a friend of mine had a smae kind of issue. He solved it by updating the iLo 2.0 firmware. I used the 1.82 firmware now, and until now the logs stay clean of the weird fan notes.

Will try to keep you up to date if anyone else might get these problems

I see now you also mentioned the firmware update. So that was in the good direction!

Alas... The problems came back after a week. After a reboot the server stays quiet for a week and the starts acting like an airplane again.

Open for any input.
