We've got a couple of PowerEdge 860 servers that recently got RHEL5u8,
and soon after I started getting nagios alerts about critical
temperatures. The nagios plugin only looks for 'cr' given by IPMI, so
the fix should be with IPMI.
We understand that the negative temp number means the offset from
meltdown for Intel-based boards.
Questions:
1 - Should something like 'ipmitool sensor thresh "Temp" unc -30'
work? ipmitool doesn't seem happy with it.
2 - If this threshold isn't settable at all, how do I make it settable?
