This article provides steps to change the Service Console IP address, gateway address, and hostname on an ESX 3.x host.
- Run the following command to set the IP address:
[root@server root]# esxcfg-vswif -i <a.b.c.d> -n <w.x.y.z> vswif0, where <a.b.c.d> is the IP address and <w.x.y.z> is the subnet mask
Note: In this example, vswif0 is the Service Console adapter that is the interface to which you are applying the IP address change.
- Open the /etc/hosts file with a text editor and modify it so that it reflects the correct IP address and hostname.
- To change the default gateway address and the hostname, edit the /etc/sysconfig/network file and change the GATEWAY and HOSTNAME parameters to the proper values.
- For the changes to take place, reboot the host or restart the network service with the command: [root@server root]# service network restart Note: This command breaks any current network connections to the Service Console.

To change the hostname, domain, and DNS servers, click the DNS Configuration tab and enter the appropriate values.
Note: Disable VMware High Availability if you do not want virtual machines to failover during the hostname IP change.
To change the default gateway, click the Routing tab and enter the appropriate value.
Update the etc/opt/vmware/vpxa/vpxa.cfg file to reflect the new settings.
Reboot the ESX host for the changes to take place.
