I don't know much about that to be honest. I don't think I would worry too much about it. All of our rack mounts appear to have the same behavior. They are above the "Lower critical", however. I think at this point these are the steps I would try: * Reset the iDRAC/BMC. Sometimes this fixes i

RE: [BULK] RE: R910/Linux CPU Heat Problems?

That's a good theory, but if you saw the youtube video i posted earlier, the PSUs are not really positioned to do much cooling, they are stacked up vertically on the left side and all 4 of them occupy maybe only 20% or less of the total cross-section of the air flow. I would think that a response t

Re: [BULK] RE: R910/Linux CPU Heat Problems?

That is interesting. That appears to be showing two sets of fans (the 7.1s and 10.*). Do you have 4 power supplies in those? I don't know off the top of my head how many PSUs an R910 takes. 10.* in ipmitool is for power supplies and 7 is for the system board (see "ipmitool sdr entity help")

We don't use OMSA here but do use ipmitool extensively. This may get you what you need. Load the following kernel modules first: ipmi_si, ipmi_devintf, ipmi_msghandler Give it a few seconds and then run: ipmitool sdr type Fan It can also be run remotely against an iDRAC (or BMC). We have had

Yeah, I tried OMSA, but for the life of me could not get it to read anything from the IPMI/BIOS interfaces. No idea why. I may just have to reboot and go into the BIOS manually and see what I can see there. Thanks! On 12/08/10 13:49, Bond Masuda wrote: > Have you checked the fan speeds? Are t

Have you checked the fan speeds? Are they at full throttle? I don't know much about the R910, but usually you can get fan speed readings from OMSA. -Original Message- From: linux-poweredge-boun...@dell.com [mailto:linux-poweredge-boun...@dell.com] On Behalf Of Erich Weiler Sent: Wednesday,

A few additions: I would highly recommend checking thumbscrews on the heat sink if the CPUs are legitimately hot. Thermal paste distribution on the CPUs may cause issues too. Also, "rdmsr -f 23:16 -d 0x1a2" will return the temperature threshold in degrees C. If you hit that temperature the c
