I have moved an EXSi 5.5 host to a new subnet at a different physical site. The host was identified by IP not the DNS name. After starting Vcenter I realized my mistake. The host is still identified by the old IP so it appears as disconnected. I hoped I would be able to simply change the IP address identification, but haven't been able to see how to do this. I also tried to remove the host (this configuration has one datacenter and one host), but I'm unable to do that. I cannot add the host (with the new IP) as I get an error message that the datastore is identified with the original host.
Is there an easy way out of this?
