We had an issue in our 5.0 vCenter where HA did not appear to be functioning correctly. When I viewed the HA Cluster Status, it showed 4 hosts in initialization status and 1 connected to the master. All VM's were showing as protected. As part of troubleshooting, I reconfigured HA on the master. Once completed, the Cluster status showed the 5 hosts now connected to the master. The only problem was a large majority of the VM's now had HA alarms.
The logs indicate that HA unsuccessfully failed over the VM, stating that the operation is not allowed in the current state. I want to know why this would happen after simply reconfiguring HA on the master? Additionally, there is no issue on the host in question. Why would HA be trying to failover? Is there anything I can do to prevent this from occurring in the future?
