Im trying to add two hosts to VmWare VCenter Server 5.1 when it comes to adding the second host I get the error message that the host is already connected when its not - any ideas please?
Please check whether the host's names resolve to the correct IP address, i.e. check whether there's a wrong DNS entry.
Managed to overcome this by adding the second host to a cluster then moving it out - strange why this should happen, any ideas why?
I was able to avoid this issue in a similar way:
I added the host to another vcenter instance. This successfully unassociated it with the current vcenter.
I then added it back.
restart Management services on the host
