ESXi Temperature Threshold Values and Alarms

I have a VSA cluster consisting of 2 physical Dell Poweredge servers.

In vSphere Client, if I highlight either box and go to the Hardware Status tab there is a 'Temperature' entry listed when viewing the Sensors.  Beneath this there are some threshold values defined. For example the Critical Threshold values are currently a range of 3 to 50 degrees Celsius.  Is there a way to tweak these values so that I can test an alarm email?

At present it is reporting the actual temp as 20C and the alarm is supposed to email me if the thresholds are breached but I have to find a way of triggering this without putting the servers in a deep freeze or setting them alight!

Before I have to resort to downing everything to see if these values are set in the Dell BIOS I just thought I'd ask if a tweak was possible via VMware?

Thanks

The predefined alarms can only be edited at the "root" level of Virtual Center.  In other words if your virtual center is called:

abc.domain.com

Highlight the above and then click on the alarms tab, then go to definitions.  You can make changes in there.

Values can be tweaked using Dell Open Manage to manage you server.

Thanks.

I looked at the domain level for the Host Temperature Alarm and there don't seem to be values I can alter. I just found things to do with a variable 'Temperature' and its states - green to red?

Do you mean installing Dell OM on a Windows Server (or servers) sitting on the host(s) and setting up the temperature threshold values (and email alarms) there or is there a way to access and control/set the ESXi hosts directly from Dell OM?

Does that make sense??

You will have to install Dell OpenManage Server Administrator on ESXi hosts.

I never realised that trying to do such a 'simple' thing would be so involved!! Either of the approaches I've marked would seem to do the trick but I just don't have the time at the moment to do this.  I'll get around to it at some point. I do appreciate the tips though.

Thanks all.
