Sun Cluster 3.1 Data Service for Oracle Parallel Server/Real Application Clusters Guide

How to Remove Nodes From the RAC Framework Resource Group by Using the scrgadm Utility

  1. On one node of the cluster, become superuser.

  2. Boot in noncluster mode the nodes from which you are removing Sun Cluster Support for Oracle Parallel Server/Real Application Clusters.

  3. For the RAC framework resource group, specify a node list that contains only the nodes that are to remain in the RAC framework resource group.

    This node list must not include the nodes that you are removing.


    # scrgadm -c -g resource-group \
  -y nodelist=nodelist \
  -y maximum_primaries=num-in-list \
  -y desired_primaries=num-in-list
    -g resource-group

    Specifies the name of the RAC framework resource group from which you are removing nodes. If this resource group was created by using the scsetup utility, the name of the resource group is rac-framework-rg.

    -y nodelist=nodelist

    Specifies a comma-separated list of cluster nodes that are to remain in the RAC framework resource group. This node list must not include the nodes that you are removing.

    -y maximum_primaries=num-in-list

    Specifies the number of nodes on which Sun Cluster Support for Oracle Parallel Server/Real Application Clusters is to be enabled. This number must equal the number of nodes in nodelist.

    -y desired_primaries=num-in-list

    Specifies the number of nodes on which Sun Cluster Support for Oracle Parallel Server/Real Application Clusters is to be enabled. This number must equal the number of nodes in nodelist.

Note –

After you have removed nodes from the RAC framework resource group, you can optionally uninstall the Sun Cluster Support for Oracle Parallel Server/Real Application Clusters software packages from the nodes that you removed.
