1. If you would like to turn off the hardware alarms, you can turn off from the vCenter server only.
There is Cisco bug: CSCve10234 on C-series servers throwing temperature alers.
The problem is not a temperature issue. Rather it is something else and this is a generic message being thrown after a CPU is hung due to some sort of interop issue
this issue need to check drivers and firmware Interoperability, OS, etc, troubleshooting.
I got the warnings to go away by clearing the event log on the Cisco management panel. It was misinterpreting messages about a DIMM that went bad years before I got here. However, it still keeps throwing out an alarm about the fan status that is totally false. I turned off that alarm at the vcenter level. I hadn't thought to look there. Thanks. There are only 2 servers on that, and both are the same and have their own hardware monitoring, so that shouldn't be an issue.
