We have a number of HP DL380 G5 servers at our customers sites. Some run W2K3, other RHEL 4. I've been asked about automatic temperature related shutdown, and I'm having trouble finding definitive answers.
Can you tell me:
- what are the temperature thresholds for this server, or how can I find them?
- what is the system behaviour when the temperature reaches these thresholds?
N.B. The Linux servers do not have any of the HP management packages installed. The BIOS has 'Thermal Shutdown' set to enabled.
Thanks, Sean.
Solved! Go to Solution.

Re: DL380 G5 Temperature related behaviour
enter ILO and check under temperature sensors, it will tell you the current temp and it limits

Re: DL380 G5 Temperature related behaviour
as juan quesada says having no SMHP you get that from ilo 2 page so will see the thresholds and for the behavior you can either let server continues working or shtdown when the threshold is exceeded that can be configured in BIOS(linux server since they don't have HP tools) or System Management homepage (SMHP) in Home -> system -> cooling and temperature (windows servers)
regards

Re: DL380 G5 Temperature related behaviour
There are some points I'd like to clarify. The BIOS 'Thermal Shutdown' setting controls whether or not the server is shutdown when a threshold is exceeded. Which threshold is this? Is this a controlled software shutdown, or immediate power removal?
I thought there was a hard-wired immediate shutdown function as well, which activates regardless of the BIOS settings. I'd guess this is triggered when the temperature reaches the upper threshold. Am I correct?
Sean.

Re: DL380 G5 Temperature related behaviour
if the TEMPERATURE threshold is Exedded the hardware (BIOS) will start a graceful shutdown no matter which OS the server is running.
the limits are inside of ILO, check the logs, it will tell you current and limits

Re: DL380 G5 Temperature related behaviour
The iLO shows two thresholds for each temperature reading; Caution, and Critical. Would I be correct in assuming that the 'Critical' temperature threshold is the one that activates the shutdown? And the Caution level is only effective when the HP management s/w is running?
Another question occurs. There are 7 temperature readings; I/O board zone, Ambient Zone, CPU1 (x2), Power Supply Zone and CPU 2 (x2). Is a shutdown instigated when any of these reached the appropriate threshold?
Thanks again, Sean.

SolutionYes, if a cautionary/critical level is detected in any of those zones, the actions above will be executed.
