I have a cluster that has been online for months. Now I can no longer manage it from my vSphere Web Client. In fact, I don't even know if it's still actually a cluster.
There are two hosts in the cluster and when I go to Related Objects, Hosts, I see the two hosts:
Both show State: connected.
Both show Status: Alert.
Both show red exclamation mark on the name.
For one of them I tried Reconfigure vSphere HA host but got:
Cannot complete login due to an incorrect user name or password.
Target: Host IP
In Related events I see "vSphere HA agent is disabled"
I do know the root pw on both hosts and can log in using that with simple vSphere Client on another windows machine.
I also obviously know the VSPHERE.LOCAL\\Administrator (don't know why 2 \\) password, since I am logged in to the Web Client.
Any ideas how to get my cluster back?
