I have an ESX 3.5 Host that is reporting "HA agent on <server.domain> in cluster <server.domain> has an error" in the Host summary screen. The problem is that this host is not a member of a cluster and never has been. I have no option to configure HA. The host & it's VMs appear to be running fine so this may be only a cosmetic issue but I would like to clear it up. Thanks for any help.
Do you have an HA cluster of the same name as the vm is complaining about?
You can also try restarting the hostd on the server, 'service mgmt-vmware restart' and the vc agent, 'service vmware-vpxa restart'
I have 3 clusters but their names are not in the least similar to the host name. Restarting hostd - 'service mgmt-vmware restart' appears to have cleared it up though. Thanks for you help.
