I have 3 ESX Hosts. All 3 ESX hosts are with ESX3.5 version. Yesterday ESX01(1st host) Host is upgraded with Update 4 and with latest patches where as other 2 ESX hosts remain same. Now I want to Manually migrate the VM from ESX03 (3rd host) to ESX01 (1st host). when i tried doing it it failed and gave error as "operation timed out". From ESX03 (3rd host) to ESX02(2nd host) we are able to migrate the VM manually without any issue.
Can anyone suggest ?
I am unable to vmkping to other hosts from ESX01. where as vmkping is working from ESX02 to ESX03. Giving error as " getaddrinfo() for "esx03-usus" failed (Resource temporarily unavailable)"
Verify that VMotion interface if properly configured on ESX1.

Make sure that vmkernel interface is up. Looks like the address can't be retrieved. Are you trying to vmkping to the IP address, or the hostname for esx03? Make sure DNS is working correctly also.
I checked the VMotion interface is properly configured on ESX1 and able to ping the ping the Vmotion ipaddress from all the 3 ESX hosts. what about the Vmkping concept. If it is not pinging any troubleshooting part?
DNS is configured properly and we are able to ping the host name too. Could you let me know whts more i need to check ?
Ping exercises the service console interface. vmkping exercises the vmkernel interface. That's the difference. If you can't vmkping the other vmkernel interface, then traffic from the vmkernel interface is not making it out or to the other hosts' vmkernel interfaces.
Have you verified that all storage is accesible and mapped to all hosts and that your port groups and Storage are mapped using the same name / method (ie - all storage is mapped using either IP address, OR Hostname - consistently accross all hosts)
Also, do you have VMSwap enabled on all hosts?
