How to Remove a Node From a zpool Device Group

Use this procedure to remove a cluster node from the list of potential primaries of a zpool device group.

1. Assume the root role or a role that provides solaris.cluster.read and solaris.cluster.modify authorization on a node in the cluster.
2. Verify that the node being removed is still a member of the device group's node list and that the device group type is zpool.

   phys-schost-1# cldevicegroup show devicegroup
   
   === Device Groups ===
   
   Device Group Name:                              gpool
      Type:                                            ZPOOL
      failback:                                        false
      Node List: phys-schost-2,phys-schost-1
      preferenced:                                     false
      autogen:                                         false
      numsecondaries:                                  0
      ZFS pool name:                                   gpool
      poolaccess:                                      global
      readonly:                                        false
      import-at-boot:                                  false
      searchpaths:                                     /dev/dsk 

3. Ensure that the node being removed is not the primary of the device group.

   phys-schost-1# cldevicegroup status gpool
   
   === Cluster Device Groups ===
   
   --- Device Group Status ---
   
   Device Group Name     Primary           Secondary           Status
   -----------------     -------     ---------     ------
   gpool                 phys-schost-2     phys-schost-1       Online 

4. Remove the node from the device group.

   phys-schost-1# cldevicegroup remove-node -n phys-schost-1 gpool
