Host connection and power state alarm

Hi

I'm hoping someone here may be able to offer some assistance.

We have 12 hosts each on a Cisco UCS blade, and 3 hosts have an alarm triggered advising of a 'Host connection and power state' issue.

To my and my colleagues knowledge, there have been no drop outs in connection to the hosts and everything seems to be functioning normally.

I have ruled out a time difference between the hosts and our vCenter server (which is virtualised).

Is there anywhere else I should be checking or looking for? Not sure which log would contain errors pertaining to the alarms.

We are running ESXi 4.1.0 659051.

Thanks in advance
