Perform this procedure to remove a node from the cluster.
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.
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.
Become superuser on a node in the cluster other than the node to remove.
Remove the node from the cluster.
# scconf -r -h node=node-name |
Verify the node removal by using scstat(1M).
# scstat -n |
Do you intend to uninstall Sun Cluster software from the removed node?
If yes, go to How to Uninstall Sun Cluster Software From a Cluster Node. Or instead, you can reinstall Solaris software on the node.
If no, to physically remove the node from the cluster, remove the hardware connections as described in the Sun Cluster Hardware Administration Manual for Solaris OS.
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 --------- ------ Cluster node: phys-schost-1 Online |
To uninstall Sun Cluster software from the removed node, see How to Uninstall Sun Cluster Software From a Cluster Node
For hardware procedures, see the Sun Cluster Hardware Administration Manual for Solaris OS.
For an overall list of tasks for removing a cluster node, see Table 7–3.
To add a node to an existing cluster, see How to Add a Node to the Authorized Node List.
