UNSOLVED
VERY HOT SAS's!
Hi everyone,
I have an OUT OF WARRANTY T710 that for some reason is burning up SAS drives. I pulled one out and it was so hot it burned my hand (and I have some tough hands!).
The rear fans are turning, and nice and clean.
What could cause this? I could get some rear fans off eBay and hope for the best, but I am not a "swap and hope" kind of guy. I would rather narrow it down.
Could it be a SAS backplane problem?
What tells these fans to go high or low?
I would think there is a thermistor somewhere.
Everything is up to latest firmware.
Any help would be appreciated!
Thanks
UPDATE:It seems that this is not isolated to just the drives, as the entire system is overheating. PROCS are too hot too.
The four rear fans are spinning but they are not going to a higher RPM as the temp increases.
I also noticed that when you open the cabinet door on my other T710's, the fans all go to a high RPM, where as this one does not.
Am I talking to myself here? I used to get real good responses in this forum. but now just dead air....
Hmmm

No, just busy. I am also not sure what to tell you. In OMSA what does it show for the fan speeds? Normal? I know you said you updated the firmware, but just to be sure, you have updated the iDRAC to the latest version? It is the iDRAC, not the BIOS, that controls the fans and system temp monitoring. You can't control the fan speeds - only the threshold for warning and error level actions.

Are your drives certified Dell drives? Their firmware also up to date? Any third-party expansion cards installed?
