Configuring nodes

Start of changeNodes are systems or logical partitions that are participating in an IBM® i high availability solution.End of change

There are several tasks related to node configuration. When you use the Create Cluster wizard, you can configure a simple two-node cluster. You can add can add additional nodes up to a total of 128. Depending on the technologies that comprise your high-availability solution, additional node configuration tasks might be required.
  • Starting nodes
    Starting a cluster node activates clustering and cluster resource services on a node in an IBM i high availability environment.
  • Enabling nodes to be added to a cluster
    Before you can add a node to a cluster, you need to set a value for the Allow add to cluster (ALWADDCLU) network attribute.
  • Adding nodes
    The IBM i PowerHA® graphical interface allows you to create a cluster with multiple nodes. After the cluster has been created you may add additional nodes through an active node in the cluster. A cluster can contain up to 128 nodes.
  • Adding a node to a device domain
    A device domain is a subset of nodes in a cluster that shares device resources.
