VMware vSphere ESXi HAI was playing around with VMware vSphere ESXi 4.1 recently and I found the warning message “HA initiated a failover action in cluster your-cluster-name in datacenter your-datacenter-name” keep show on my vCenter. Nothing has been changed, HA working like a charm, no VMs have been reboot and the warning message just annoying.

The solution are pretty simple.

Option 1:
1. Turn OFF VMware HA on Cluster Feature setting.
2. Enable VMware HA setting again.

Option 2:
1. Enter maintenance mode
2. Remove ESXi hosts from cluster
3. Add ESXi hosts back to cluster
4. Exit maintenance mode

Done! The annoying warning message will go away.
