Have 2 servers running esxi 4.1 and using vcenter and vsphere essential + 4.1.  I created a HA cluster without DRS.  I moved the hosts to the cluster but I get an error and it disables HA.  the error i get is "Reconfigure HA host 1.1.1.1 Cannot  complete  the  configurati- on of the HA  agent on the  host.  Misconfiguration in the  host  network  setup.

if i check more details it says "Cannot complete command 'hostname -s' on host 1.1.1.1, or returned incorrect name format

any idea what is causing this?

do you have DNS setup correctly?

and are you using fully qualified domain names, that can be resolved, with reverse lookup?

it certainly seems like it cannot resolve it's own hostname correctly?

are you talking about the vmhosts themselves?

the VMware ESX hosts.

you could login to the ESX host via ssh, and type

hostname -s <ip addresss> and it should return the hostname of the ESX server.

e.g.

~ # hostname -s 172.245.138.101
esxdev001
~ #

also check the /etc/hosts files, because there should be an entry for your server in there as well.

ok, it accepted it, i just changed the hostname manually and restarted dns and the management network.  So now I have a yellow exclamation saying the management network has no redundacy, but i only have 1 NIC plugged in right now so i'm not worried about that.. Thanks!
