Shutting Down a Clustered Configuration (BUI)

Use this procedure to shut down a clustered configuration.

  1. From one of the peer controllers, go to Configuration > Cluster.
  2. Determine the state of both controllers.

    In the following figure, the active controller is controller-a, and the standby controller is controller-b.


    image:Controller Status

    Use the following table to determine the state of each controller.

    controller-a
    controller-b
    Condition
    image:Image showing the status on icon Active
    image:Image showing the status on icon Active
    Both controllers are running in a normal clustered condition.
    image:Image showing the status on icon Active (takeover completed)
    image:Image showing the status off icon Ready (waiting for failback)
    controller-a owns all of the resources and is the active controller. controller-b, is in standby mode and has no resources. To limit the number of times a pool is moved, shut down the standby controller first.
    image:Image showing the status on icon Active (takeover completed)
    image:Image showing the service enable icon Rejoining cluster ...
    controller-b is rebooting and controller-a has all resources.
    image:Image showing the status on icon Active (takeover completed)
    Unknown (disconnected or restarting)
    controller-b is powered off or rebooting, all of its cluster interconnect links are down, or clustering has not yet been configured.
  3. Log in to the BUI of Controller B and click the power icon image:Image showing the power icon on the left side under the masthead.
    Note -  To limit the number of times a pool is moved, shut down the standby controller first.
  4. From the BUI of Controller A, go to Configuration > Cluster to confirm that Controller B is powered off, with the cluster state: Unknown (disconnected or restarting).
  5. From the BUI of Controller A, click the power icon image:Image showing the power icon on the left side under the masthead.
  6. (Optional) To confirm that both controllers are powered off, log into the Oracle ILOM and enter : 
    ->show /SYS power_state

    For information about accessing ILOM, see Logging in to Oracle ILOM Remotely Using a Command Line Interface in Oracle ZFS Storage Appliance Customer Service Manual.

  7. Power off the disk shelves.
    1. Place the power supply on/off switches to the "O" off position.
    2. Disconnect the power cords from the external power source for the cabinet.
      Note -  All power cords must be disconnected to completely remove power from the disk shelf.

      For more information, see Powering Off a Disk Shelf in Oracle ZFS Storage Appliance Installation Guide.
