R200 IPMI: negative Temp value

[Björn Boschman]

Hi,

I recently bought several R200s and want to monitor things like CPU-Temp via nagios.
As I cannot find any sources for OpenManage I was thinking of using ipmitool.

I loaded the following kernel-modules: ipmi_devintf ipmi_si ipmi_msghandler

And the resulting output of ipmitool sdr | grep -v "Not Readable":

Temp             | -58 degrees C     | cr
Planar Temp      | 35 degrees C      | ok

System: Ubuntu 8.04.1 i386

Why is Temp a negative value and why is it critical?

If more input is required just ask
