Recently I've had the technicians switch off the cooling system in the server room, without notifying me first.
Since the compute nodes do have IPMI cards from different manufacturers installed, I'd like to simply configure via ipmitool a threshold temperature to switch off the compute-nodes. I've found that you can set the upper critical temperature to 58 degree Celsius via
ipmitool <options> sensor thresh "Ambient Temp" ucr 58.000
but have not found how to tell it what to do, once this temperature is reached. Also, I'd like to know how to email me, or add temperature warnings to the logwatch messages, at a lower temperature.
