With the warmer summer days starting to hit, my server is increasingly going into thermal protection shutdown due to temp sensor #21 reaching critical level (58*C), as reported in ILO.

The fans are all running fine but unfortunately, the server is not in a climate controlled room and there isn't much I can do about the ambient temperature. However, if I know where sensor #21 is, I can try to improve the airflow around that area. And if it's an IC, I can add/beef up the heatsink to improve cooling.

Does anybody know where that sensor is?

Many thanks in advance.

  • Are you sure you have a DL180 G6? Our sensor count is different and the thresholds are not the same. What is the disk layout and RAID controller setup in this server? – ewwhite Jun 16 '14 at 11:39
  • It's a DL180 G6 SE326M1 with 25xSSF disks and a P812 – Seb Boulet Jun 16 '14 at 13:04
  • A P812 in that server doesn't quite make sense unless you're running external storage as well. I'd be using a P410. In either case, it's still a supported configuration. I'd ensure that your firmware is up-to-date on the system BIOS and ILO. If no change, I'd call HP. – ewwhite Jun 16 '14 at 13:27
  • Thanks for your input. Yes, the P812 is driving an MSA60 with 3TB SATA drives and the internal SFFs. I last ran HP SUM in March but I'll give it another go. – Seb Boulet Jun 16 '14 at 13:54
  • That's pretty recent. Call HP or see if you have a BIOS option for "increased cooling" because of the P812's presence. Can you also output `hplog -f` ? – ewwhite Jun 16 '14 at 14:34

Does it matter which sensor #21 is? What would you actually do about it?

Can you check your ambient temperature? What can you control about your environment to keep that within a reasonable range? Are you absolutely sure you don't have a failed fan?

--edit--

It makes sense to ensure the firmware of ALL of your components is up-to-date. For you, that means your system BIOS, ILO, RAID controller, NIC, backplane and disks. These can all be covered by the HP Support Pack for ProLiant bootable DVD. Please download and run.

Check the internal health LED on the server. If you're running a supported version of Linux or Windows, install the HP management agents and check the output of hplog -t to get temperature sensor information. The output of a standard DL180 G6 config looks like the following. Correlate your results with mine:

note: there are four fans in this system

    Well, what he CAN do is make sure that the sensor reading makes sense. I have 2 SuperMicro cases, identical, one above the other. In one I get sensor temperature warnings on the SAS backplane, the other is somehow 20 degree less in temperature. We checked airflow and room temperature multiple times - this ONE sensor is off. WAY off. – TomTom Jun 16 '14 at 07:44
