Rename existing ESXi host

Rename existing ESXi host

Remove your host from its cluster if it belongs to one.

If the ESX host is managed by vCenter, disconnect and remove the ESX host from the vCenter.

Make the modifications in your DNS environment to reflect the correct name and IP association for the new name.

winscp and edit the hostname in the following files;

/etc/hosts

/etc/sysconfig/network

 Launch Putty and run this command:

esxcfg-advcfg -s hostname /Misc/hostname

(where /hostname is the new hostname for the ESX host).

Reboot and enjoy.
