Changing the role of a node in a cluster

You can assign the Control node role to any cluster node. The other nodes will have the Secondary node role. For example, you may need to change the roles due to a failure of the Control node, or if you have to remove the application from this server.

To assign the Secondary node role to the Control node:

1. In the application web interface window, select the Nodes section.
2. In the cluster nodes table, select the Control node.

   The node settings window opens.

3. Click Change role to Secondary node.

The Control node will become a Secondary node. The web interface of the Secondary node opens.

To assign the Control node role to a Secondary node:

1. In the application web interface window, select the Nodes section.
2. In the cluster nodes table, select a Secondary node.

   The node settings window opens.

3. Click Go to manage node.

   Authorization page opens in a new browser window.

4. Enter the name and password of the application privileged user.

   A user that has access to the functionality of the application management console. The items available in the management console menu depend on the role that is assigned to the user.

   The web interface of the Secondary node opens.

5. Click Change role to Control node.
