The other day I had an ESXi host loose power. After the host came back up, it had an error "HA agent disabled on on host in cluster".
I have had this happen before after rebooting a host. What usually fixes it for me is to take the host into maintenance mode then take it back out. I did that and it still has the error. So I ran the option "Reconfigure for VMWare HA" but it gives an error 'HA agent on < hostname> in cluster <Cluster name> has an error "HA agent on the host has been shut down"'.
I rebooted the host again and tried the steps above but I am unable to get the HA agent to start on the host. Any suggestions?
As an FYI, this host was a working member of my HA cluster and when the host lost power, the VMs all came up on other members of the HA cluster as they should have.
