Adding a New Cluster Node

When you add a new node to a cluster that is in a partnership, you must perform additional tasks on that node to make it an active participant in the disaster recovery framework configuration.

How to Add a New Node to a Cluster in a Partnership

Perform all steps from the new node.

  1. Add the new node to the cluster.

    Follow procedures in Chapter 8, Administering Cluster Nodes in Administering an Oracle Solaris Cluster 4.4 Configuration.

  2. Install disaster recovery framework, data replication, and application software on the new node.
  3. If the cluster with the new node is the primary for any activated protection groups, remove application resource groups from those protection groups.

    This step is necessary to avoid application downtime.

    # geopg remove-resource-group resource-group protection-group
  4. Deactivate all protection groups that are active on this cluster locally.
    # geopg stop -e local protection-group
  5. Stop the disaster recovery framework.
    # geoadm stop
  6. Re-enable the disaster recovery framework.

    This action recreates each disaster recovery framework resource group and adds all nodes in the cluster, including the new node, to the node list.

    # geoadm start
  7. Reactivate the protection groups that you deactivated in Step 4.
    # geopg start -e local protection-group
  8. Restore any application resource groups that you removed in Step 3.
    # geopg add-resource-group resource-group protection-group
