Re: CPU Fan failed

Try the same for the other cell board and attach the result.

(this output is too hard to read due to the format).

Hope this helps!

Re: CPU Fan failed

Yes, that's correct.

Unlike other cell boards this one can have up to 5 fans, the fan mounted on CPU0 on cell 0 has failed and needs to be replaced (cpu module).

Hope this helps!

Torsten.

Re: CPU Fan failed

Hi,

See the * (Astric) symbol. means, Cpu0 in Cell0 failed and need to be replace. If ur not replacing the fan, CPU temperature will increase and the CPU will also fail. If it happens your srver will go through a reboot, while coming up, this perticular CPU will be marked as failed, and the server will run in degraded mode. Which will reduce server performance.

Re: CPU Fan failed

The Fan has been replaced. We noticed that the spring that holds the fan on the CPU was loose.

They were both replaced.
