To convert a single-node NSX Advanced Load Balancer Controller deployment into a three-node deployment, use the following steps.

In this procedure, the Controller node that is already deployed in the singe-node deployment is referred to as the incumbent Controller.

Procedure

  1. Install one new NSX Advanced Load Balancer Controller node. During installation, configure the following settings:

    • Node management IP address

    • Gateway address

  2. Connect the management interface of each new Controller node to the same network as the incumbent Controller. After the incumbent Controller detects the two new Controller nodes, the incumbent Controller will become the primary (leader) Controller for the three-node cluster.
  3. Use a web browser to navigate to the management IP address of the primary (leader) Controller.
  4. Navigate to Administration > Controller > Nodes, and click Edit. The Edit CLUSTER pop-up window appears.
  5. In the Controller Cluster IP field, enter the shared IP address for the Controller cluster.
  6. In the Public IP Address or Hostname field, enter the management IP addresses of the new Controller nodes.
    Note:

    Password for the admin account is required for each node of the cluster for configuring cluster in AWS Cloud.

  7. After these steps, the incumbent Controller becomes the primary (leader) for the cluster and invites the other Controllers to the cluster as members. NSX Advanced Load Balancer then performs a warm reboot of the cluster. This process can take two- three minutes. The configuration of the primary (leader) Controller is synchronized to the new member nodes when the cluster comes online following the reboot.
