Add a new standby node after the original standby node failed by using the GUI

In this scenario, the standby node of an HA pair has failed. So, you must add a new standby node. System administrators can use the High Availability page in the Amlen WebUI.

The two Eclipse Amlen appliances must be physically connected. For more information about connecting appliances, see Configuring the system for High Availability. The administrative state (AdminState) of the two appliances must also be enabled. Go to the Network Settings page to set the administrative state of the appliances.

You can configure appliances for high availability by using the Amlen WebUI, or by using the command line. For more information about using the command line to configure appliances for high availability, see Add a new standby node after the original standby node failed by using the command line. In this scenario, the content of the store and configuration of Appliance A is preserved and Appliance A does not require restarting.

1. Click System Control in the Appliance menu.
2. Select maintenance from the Runmode list.
3. Stop the server by clicking Stop the server.
4. Start the server by clicking Start the server.
5. Select the clean store check box.

  The high availability group is used to automatically configure appliances to pair with each other. The value must match the value on Appliance B. When this value is set, you do not need to provide replication or discovery addresses.

6. Click Restart Now.

When the HA pair is up and running, you can view the status of each appliance from the Status menu on the Amlen WebUI. You can view further information on the status of the appliance by using the System Control page. You can view further information about the high availability role of the appliance by using the High Availability page.
