Performing Zone Cluster Administrative Tasks

You can perform other administrative tasks on a zone cluster, such as moving the zone path, preparing a zone cluster to run applications, and cloning a zone cluster. All of these commands must be performed from the voting node of the global cluster.

Table 9-3 Other Zone-Cluster Tasks

How to Remove a Zone Cluster

You can delete a specific zone cluster or use a wildcard to remove all zone clusters that are configured on the global cluster. The zone cluster must be configured before you remove it.

1. Become a superuser or assume a role that provides solaris.cluster.modify RBAC authorization on the node of the global cluster.

   Perform all steps in this procedure from a node of the global cluster.

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

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

   ---

   Note - This step is performed from a global-cluster node. To perform this step from a node of the zone cluster instead, log into the zone-cluster node and omit -Z zonecluster from the command.

   ---

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

Example 9-11 Removing a Zone Cluster From a Global Cluster

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

phys-schost# clzonecluster halt sczone

phys-schost# clzonecluster uninstall sczone

phys-schost# clzonecluster delete sczone

How to Remove a File System From a Zone Cluster

A file system can be exported to a zone cluster using either a direct mount or a loopback mount.

Zone clusters support direct mounts for the following:

• UFS local file system

• Oracle Solaris ZFS (exported as a data set)

• NFS from supported NAS devices

Zone clusters can manage loopback mounts for the following:

• UFS local file system

• UFS cluster file system

You configure an HAStoragePlus or ScalMountPoint resource to manage the mounting of the file system. For instructions on adding a file system to a zone cluster, see Adding File Systems to a Zone Cluster in Oracle Solaris Cluster Software Installation Guide .

The phys-schost# prompt reflects a global-cluster prompt. This procedure provides the long forms of the Oracle Solaris Cluster commands. Most commands also have short forms. Except for the long and short forms of the command names, the commands are identical.

1. Become superuser on a node of the global cluster that hosts the zone cluster.

   Some steps in this procedure are performed from a node of the global cluster. Other steps are performed from a node of the zone cluster.

2. Delete the resources related to the file system being removed.
   1. Identify and remove the Oracle Solaris Cluster resource types, such as HAStoragePlus and SUNW.ScalMountPoint, that are configured for the zone cluster's file system that you are removing.

      phys-schost# clresource delete -F -Z zoneclustername fs_zone_resources

   2. If applicable, identify and remove the Oracle Solaris Cluster resources that are configured in the global cluster for the file system that you are removing.

      phys-schost# clresource delete -F fs_global_resources

      Use the -F option carefully because it forces the deletion of all the resources you specify, even if you did not disable them first. All the resources you specified are removed from the resource-dependency settings of other resources, which can cause a loss of service in the cluster. Dependent resources that are not deleted can be left in an invalid state or in an error state. For more information, see the clresource(1CL) man page.

   ---

   Tip - If the resource group for the removed resource later becomes empty, you can safely delete the resource group.

   ---

3. Determine the path to the file-system mount point directory.

   For example:

   phys-schost# clzonecluster configure zoneclustername

4. Remove the file system from the zone-cluster configuration.

   phys-schost# clzonecluster configure zoneclustername

   clzc:zoneclustername> remove fs dir=filesystemdirectory

   clzc:zoneclustername> commit

   The file system mount point is specified by dir=.

5. Verify the removal of the file system.

   phys-schost# clzonecluster show -v zoneclustername

Example 9-12 Removing a Highly Available Local File System in a Zone Cluster

This example shows how to remove a file system with a mount-point directory (/local/ufs-1) that is configured in a zone cluster called sczone. The resource is hasp-rs and is of the type HAStoragePlus.

phys-schost# clzonecluster show -v sczone
...
 Resource Name:                           fs
   dir:                                     /local/ufs-1
   special:                                 /dev/md/ds1/dsk/d0
   raw:                                     /dev/md/ds1/rdsk/d0
   type:                                    ufs
   options:                                 [logging]
 ...
phys-schost# clresource delete -F -Z sczone hasp-rs
phys-schost# clzonecluster configure sczone
clzc:sczone> remove fs dir=/local/ufs-1
clzc:sczone> commit
phys-schost# clzonecluster show -v sczone

Example 9-13 Removing a Highly Available ZFS File System in a Zone Cluster

This example shows to remove a ZFS file systems in a ZFS pool called HAzpool, which is configured in the sczone zone cluster in resource hasp-rs of type SUNW.HAStoragePlus.

phys-schost# clzonecluster show -v sczone
...
 Resource Name:                           dataset
   name:                                     HAzpool
...
phys-schost# clresource delete -F -Z sczone hasp-rs
phys-schost# clzonecluster configure sczone
clzc:sczone> remove dataset name=HAzpool
clzc:sczone> commit
phys-schost# clzonecluster show -v sczone

How to Remove a Storage Device From a Zone Cluster

You can remove storage devices, such as Solaris Volume Manager disksets and DID devices, from a zone cluster. Perform this procedure to remove a storage device from a zone cluster.

1. Become superuser on a node of the global cluster that hosts the zone cluster.

   Some steps in this procedure are performed from a node of the global cluster. Other steps can be performed from a node of the zone cluster.

2. Delete the resources related to the devices being removed.

   Identify and remove the Oracle Solaris Cluster resource types, such as SUNW.HAStoragePlus and SUNW.ScalDeviceGroup, that are configured for the zone cluster's devices that you are removing.

   phys-schost# clresource delete -F -Z zoneclustername dev_zone_resources

3. Determine the match entry for the devices to be removed.

   phys-schost# clzonecluster show -v zoneclustername
   ...
    Resource Name:       device
       match:              <device_match>
    ...

4. Remove the devices from the zone-cluster configuration.

   phys-schost# clzonecluster configure zoneclustername
   clzc:zoneclustername> remove device match=<devices_match>
   clzc:zoneclustername> commit
   clzc:zoneclustername> end

5. Reboot the zone cluster.

   phys-schost# clzonecluster reboot zoneclustername

6. Verify the removal of the devices.

   phys-schost# clzonecluster show -v zoneclustername

Example 9-14 Removing an SVM Disk Set From a Zone Cluster

This example shows how to remove a Solaris Volume Manager disk set called apachedg configured in a zone cluster called sczone. The set number of the apachedg disk set is 3. The devices are used by the zc_rs resource that is configured in the cluster.

phys-schost# clzonecluster show -v sczone
...
  Resource Name:      device
     match:             /dev/md/apachedg/*dsk/*
  Resource Name:      device
     match:             /dev/md/shared/3/*dsk/*
...
phys-schost# clresource delete -F -Z sczone zc_rs

phys-schost# ls -l /dev/md/apachedg
lrwxrwxrwx 1 root root 8 Jul 22 23:11 /dev/md/apachedg -> shared/3
phys-schost# clzonecluster configure sczone
clzc:sczone> remove device match=/dev/md/apachedg/*dsk/*
clzc:sczone> remove device match=/dev/md/shared/3/*dsk/*
clzc:sczone> commit
clzc:sczone> end
phys-schost# clzonecluster reboot sczone
phys-schost# clzonecluster show -v sczone

Example 9-15 Removing a DID Device From a Zone Cluster

This example shows how to remove DID devices d10 and d11, which are configured in a zone cluster called sczone. The devices are used by the zc_rs resource that is configured in the cluster.

phys-schost# clzonecluster show -v sczone
...
 Resource Name:       device
     match:             /dev/did/*dsk/d10*
 Resource Name:       device
    match:              /dev/did/*dsk/d11*
