ProcedureHow to Remove a Node From a Scalable Resource Group

A scalable service is configured as two resource groups, as follows.

Additionally, the RG_dependencies property of the scalable resource group is set to configure the scalable group with a dependency on the failover resource group. For information about this property, see Appendix B, Standard Properties.

For details about scalable service configuration, see Sun Cluster Concepts Guide for Solaris OS.

Removing a node from the scalable resource group causes the scalable service to no longer be brought online on that node. To remove a node from the scalable resource group, perform the following steps.

  1. Remove the node from the list of nodes that can master the scalable resource group (the nodelist resource group property).

    # clresourcegroup set [-n node-zone-list] scalable-resource-group
    -n node-zone-list

    Specifies a comma-separated, ordered list of nodes that can master this resource group. This resource group is switched offline on all the other nodes. The format of each entry in the list is node:zone. In this format, node specifies the node name and zone specifies the name of a global-cluster non-voting node. To specify the global-cluster voting node, or to specify a node without global-cluster non-voting nodes, specify only node.

    This list is optional. If you omit this list, the Nodelist property is set to all nodes in the cluster.


    Specifies the name of the resource group from which the node is being removed.

  2. (Optional) Remove the node from the failover resource group that contains the shared address resource.

    For details, see How to Remove a Node From a Failover Resource Group That Contains Shared Address Resources.

  3. (Optional) Update the Load_balancing_weights property of the scalable resource to remove the weight of the node that you are removing from the resource group.
