Summary
This Knowledgebase article provides information about how to change the Neverfail Channel IP address(es), when Neverfail Engine is installed as a server pair.
More Information
There may be occasions where it is necessary to change the channel IP address(es) on a Neverfail server pair. Neverfail can accommodate the requirement with some minor configuration changes.
Procedure
To change the Neverfail Channel IP address on a Neverfail server pair, follow the steps below:
The following steps assume the server pair is configured with the Primary server as Active, and the Secondary server as Passive.
On the Primary server:
- Stop Neverfail Engine leaving the protected applications running.
- From Windows Networking and Sharing console, change the Channel IP address, ideally, it should be set in a different subnet class than the principal (public) address.
- Open the Server Configuration wizard on the Primary server and click on the Channel tab.
- Edit the channel IP address(es). The Primary server channel IP can be selected from the drop-down box. The Secondary server channel IP address needs to be filled in manually, ensuring to press ENTER once the IP address of the Secondary server is correct.
- Click Finish. (Note: If you do not press ENTER , the changes will not be stored.)
- Repeat steps 1 to 5 on the Secondary server.
- Start Neverfail Engine on the Secondary (passive) server.
- Start Neverfail Engine on the Primary (active) server and allow servers to re-sync.
