i upgraded my vcenter to 5.1 a couple days ago. since the upgrade my vShpere is telling me that HA initiated a virtual machine failover in the datacenter.
i have checked the HA configuration and it is all looking good with no problems. all the VM's are running fine and none of them have any errors or warnings. is this something that will be corrected once i upgrade my hosts to 5.1? or is there another underlying problem that might be there that i should be looking for before i upgrade the hosts to 5.1?
it could be an underlying storage issue.
do you have letency problems on your san?
Bellow is the latency warning that i am gettting. that also hits the same time that my SQL and exchange are doing maintenance.
performance has deteriorated. I/O latency
increased from average value of 959
microseconds to 29012 microseconds.
