DNS is more often the root of HA failures.

Check DNS servers online, DNS entries, local hosts file, Host Identification entry in Configuration|DNS and Routing ("Name" and "Domain").

Check entries are correct and are in the same case.

Good luck!

My issue is i want to change the hostname from :

vnware2 -> vmware2

I've tried this in the /etc/sysconfig/network, but it hasnt made any difference,

Is there anywhere else that this file needs to be changed.

Can you confirm that you have updated all the locations listed with the correct name "vmware2"?

DNS entries, local hosts file, Host Identification entry in Configuration|DNS and Routing ("Name" and "Domain").

I can confirm that i've changed the hostname in the following locations:

/etc/hosts

/etc/sysconfig/network

/etc/vmware/esx.config

Is there anywhere else i need to change the hostname ?
