How to Unconfigure a Zone Cluster

Perform this procedure to remove a zone cluster.

1. Become superuser on a node of the global cluster.

   You perform all steps of this procedure from a node of the global cluster.

2. Take offline each resource group in the zone cluster and disable its resources.

   Note –

   The following steps are performed from a global-cluster node. To instead perform these steps from a node of the zone cluster, log in to the zone-cluster node and omit “-Z zonecluster” from each command.

   1. Take each resource offline.

      phys-schost# clresource offline -Z zonecluster resource-group

   2. List all enabled resources in the zone cluster.

      phys-schost# clresource show -Z zonecluster -p Enabled === Resources === Resource: resource Enabled{nodename1}: True Enabled{nodename2}: True …

   3. Identify those resources that depend on other resources.

      phys-schost# clresource show -Z zonecluster -p resource_dependencies === Resources === Resource: node Resource_dependencies: node …

      You must disable dependent resources first before you disable the resources that they depend on.

   4. Disable each enabled resource in the cluster.

      phys-schost# clresource disable -Z zonecluster resource

      See the clresource(1CL) man page for more information.

   5. Verify that all resources are disabled.

      phys-schost# clresource show -Z zonecluster -p Enabled === Resources === Resource: resource Enabled{nodename1}: False Enabled{nodename2}: False …

   6. Move each resource group to the unmanaged state.

      phys-schost# clresourcegroup unmanage -Z zonecluster resource-group

   7. Verify that all resources on all nodes are Offline and that all resource groups are in the Unmanaged state.

      phys-schost# cluster status -Z zonecluster -t resource,resourcegroup

   8. Delete all resource groups and their resources from the zone cluster.

      phys-schost# clresourcegroup delete -F -Z zonecluster +

3. Halt the zone cluster.

   phys-schost# clzonecluster halt zoneclustername

4. Uninstall the zone cluster.

   phys-schost# clzonecluster uninstall zoneclustername

5. Unconfigure the zone cluster.

   phys-schost# clzonecluster delete zoneclustername
