Adding a Diskless or Dataless Node to a Cluster

This chapter describes how to add a diskless or dataless, non-master-eligible node to a cluster.


Process for Adding Nodes to a Cluster

This section describes how to add a diskless or dataless node to a cluster.

  1. Verify that the hardware of the new node is supported.

    For information, see the Netra High Availability Suite 3.0 1/08 Foundation Services Getting Started Guide.

  2. Verify that after adding the node, your cluster configuration will be supported.

    For information, see the Netra High Availability Suite 3.0 1/08 Foundation Services Getting Started Guide.

  3. Verify that the new node has a unique node ID and name.

    For a list of IDs and names of the nodes in the cluster, see the cluster_nodes_table file on the master node.

  4. Verify which packages and patches are to be installed.

    For information about the patches and packages required for your hardware configuration, see Netra High Availability Suite 3.01/08 Foundation Services README.

  5. Verify that the master node and vice-master node are running the Netra HA Suite.

    The configuration information is written to the master node and replicated to the vice-master node.

    1. Log in to the master node as superuser.

    2. Verify that the Netra HA Suite are running:


      # /opt/SUNWcgha/sbin/nhcmmstat -c all
      

      This command returns the status of all nodes in the cluster.

  6. Add the node:

    • To add a diskless node, use the procedure in Chapter 3.

    • To add a dataless node, use the procedure in Chapter 4.

  7. Update the network topology map to include the new node.
