How to Remove a Storage Device From a Zone Cluster

You can remove storage devices, such as SVM 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 Sun 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 8–17 Removing an SVM Disk Set From a Zone Cluster

This example shows how to remove an SVM 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 8–18 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*
...
phys-schost# clresource delete -F -Z sczone zc_rs
phys-schost# clzonecluster configure sczone
clzc:sczone> remove device match=/dev/did/*dsk/d10*
clzc:sczone> remove device match=/dev/did/*dsk/d11*
clzc:sczone> commit
clzc:sczone> end
phys-schost# clzonecluster reboot sczone
phys-schost# clzonecluster show -v sczone
