How to Remove a Node From a Zone Cluster

You can remove a node from a zone cluster by halting the node, uninstalling it, and removing the node from the configuration. If you decide later to add the node back into the zone cluster, follow the instructions in Table 8–1. Most of these steps are performed from the global-cluster node.

You can also use the Oracle Solaris Cluster Manager GUI to shut down a zone-cluster node, but not to remove a node. For GUI log-in instructions, see How to Access Oracle Solaris Cluster Manager.

  1. Assume the root role on a node of the global cluster.
  2. Shut down the zone-cluster node you want to remove by specifying the node and its zone cluster.
    phys-schost# clzonecluster halt –n node zoneclustername

    You can also use the clnode evacuate and shutdown commands within a zone cluster.

  3. Remove the node from all resource groups in the zone cluster.
    phys-schost# clrg remove-node -n zonehostname -Z zoneclustername rg-name

    If you use the procedure described in the Note in Step 2, the resource groups should be automatically removed so you might be able to skip this step.

  4. Uninstall the zone-cluster node.
    phys-schost# clzonecluster uninstall –n node zoneclustername
  5. Remove the zone-cluster node from the configuration.

    Use the following commands:

    phys-schost# clzonecluster configure zoneclustername
    clzc:sczone> remove node physical-host=node
    clzc:sczone> exit

    Note -  If the zone cluster node you want to remove resides on a system that is inaccessible or unable to join the cluster, remove the node with the clzonecluster interactive shell:
    clzc:sczone> remove -F node physical-host=node

    If you use this method to remove the last zone cluster node, you will be prompted to delete the zone cluster entirely. If you choose not to, the last node will not be removed. This deletion has the same effect as clzonecluster delete -F zoneclustername.


  6. Verify that the node was removed from the zone cluster.
    phys-schost# clzonecluster status
