Changing the address of a machine

When a cluster is in use, it might be necessary to change the address used to access a machine. For example, you might have used IP addresses to access machines but would now like to use hostnames.

To change the address of a machine

1. From the main menu, click the Administration icon.
   The Administration page opens.
   
2. In the Appliance section, click Cluster Management.
3. From the Actions drop-down on the cluster machine row in the Current Members list, select Change Address.
   The Change Member Address dialog is displayed.
4. Enter the new IP address or hostname into the Address field using one of the following formats:
   • IPv4 address (for example 192.168.1.100). Labeled v4.
   • IPv6 address (for example 2001:500:100:1187:203:baff:fe44:91a0). Labeled v6.
   • Hostname (for example wilkoapp3.tideway.com). Labeled Hn.
5. If you are changing the address of the machine whose UI you are using, click the additional Show Known Addresses to show all of the addresses that refer to this machine.
   1. Click on a displayed address to populate the Address field.
6. Click OK to change the address.
   This becomes a pending change that needs to be committed before the address is changed.
7. Click Commit Changes to change the address.
   If the hostname or address entered does not refer to the correct machine, then the changes have not been applied.
