ProcedureHow to Remove a Node From the Cluster Software Configuration

Perform this procedure to remove a node from the cluster.

Steps
  1. Be sure you have correctly completed all prerequisite tasks listed in the “Removing a Cluster Node” task map in Adding and Removing a Cluster Node.


    Note –

    Be sure you have removed the node from all resource groups, disk device groups, and quorum device configurations and placed it in maintenance state before you continue with this procedure.


  2. Become superuser on a node in the cluster other than the node to remove.

  3. Remove the node from the cluster.


    # scconf -r -h node=node-name
    
  4. Verify the node removal by using scstat(1M).


    # scstat -n
    
  5. Do you intend to uninstall Sun Cluster software from the removed node?


Example 7–12 Removing a Node From the Cluster Software Configuration

This example shows how to remove a node (phys-schost-2) from a cluster. All commands are run from another node of the cluster ( phys-schost-1).


[Remove the node from the cluster:]
phys-schost-1# scconf -r -h node=phys-schost-2
[Verify node removal:]
phys-schost-1# scstat -n
-- Cluster Nodes --
                    Node name           Status
                    ---------           ------
