Bring back the last primary node after the primary and then the standby node fails

In this scenario, the primary node fails and the standby node takes over as the new primary node. Before a new backup can be setup, the new primary node fails. You must restart new primary node and set up a new standby node.

Use the following information to understand the steps that are required to configure a new standby appliance (Appliance C) after the original primary appliance (Appliance A) fails and the standby node (Appliance B) that has taken over as the primary also fails. The content of the store and the configuration of Appliance B is preserved and Appliance B requires a restart.

You can configure appliances for high availability by using the IBM® Watson IoT Platform - Message Gateway Web UI, or by using the command line. For more information about using the IBM Watson IoT Platform - Message Gateway Web UI to configure appliances for high availability, see Primary node fails then standby node fails, bring back last primary node by using the GUI. For more information about using the command line to configure appliances for high availability, see Primary node fails then standby node fails, bring back last primary node by using the command line.
