Add nodes to clusters

By default, the Engine Editor displays two nodes in the Clustering pane. You can add new nodes to the cluster.

Before you begin

Before adding a node to the configuration, install the physical engine device and connect the cables. At a minimum, connect the cables for the interfaces that enable communication with the Management Server and between the clustered engines.

If the device has a working configuration from previous use, use the NGFW Initial Configuration Wizard (sg-reconfigure) on the command line to return the device to the initial configuration state. Set up the initial configuration state before connecting the device to the network. Do not make initial contact with the Management Server.

Steps

  1. Right-click the cluster and select Edit <element type>.
  2. In the navigation pane on the left, browse to General > Clustering.
  3. Click Add Node.
  4. Give the node a unique Name.
  5. In the Nodes table, review and update the information in the IP Address, Contact IP Address, and Comment columns for each NDI. (Double-click the value you want to change.)
    Firewall CVI details are identical between the nodes, so adding a node to a Firewall Cluster does not require changing the CVI configuration in any way.
  6. Click OK.
  7. Click Save.
  8. Save the initial configuration for the new engine node to create a one-time password.
  9. Make initial contact between the new engine and the Management Server.
  10. Refresh the policy of the cluster to transfer the changes to the engines.
    To refresh the policy of the existing node before the new nodes are initialized, disable the inactive nodes on the Clustering pane in the Engine Editor. Otherwise, the policy installation fails due to a lack of connectivity to all nodes.
