Add a node to a cluster

You can add a node to a cluster using iSeries™ Navigator or commands.

Using iSeries Navigator

This requires Option 41 (HA Switchable Resources) to be installed and licensed.

The simple cluster supported by iSeries Navigator can be made up of a maximum of four nodes. If four nodes already exist in the cluster, the Add Node option is disabled. If your clustering needs extend beyond four nodes, you should use Cluster commands and APIs or a Cluster middleware IBM Business Partner product to support up to 128 nodes.

To add a node to an existing cluster, follow these steps:

  1. In iSeries Navigator, expand Management Central.
  2. Expand Clusters.
  3. Expand the cluster for which you want to add a node.
  4. Right-click Nodes, and select Add Node...
