Detach a NAS Controller

Detach a NAS controller only if the NAS controller needs to be replaced with a new NAS controller. After you detach a NAS controller, it resets to its factory defaults and powers off, if possible. Otherwise, you must reinstall the FluidFS software to reset the NAS controller to its factory defaults.

About this task

Only one NAS controller can be detached from a NAS appliance at a time. Detaching a NAS controller disconnects client connections while clients are being transferred to other NAS controllers. Clients will then automatically reconnect to the FluidFS cluster. While a NAS controller is detached from the FluidFS cluster, SMB shares and NFS exports remain available (although performance might decrease because data is no longer cached); however, most FluidFS cluster configuration changes are not allowed.
CAUTION:Detach a NAS controller only under the direction of technical support.

Steps

  1. In the Storage view, select a FluidFS cluster.
  2. Click the Hardware tab.
  3. In the Hardware view, expand Appliances to select an appliance ID and a NAS controller ID.
  4. Click Detach.
    The Detach dialog box opens.
  5. Click OK.
    The Detach dialog box displays the progress of the detach process. If you close the dialog box, the process will continue to run in the background.

    The NAS controller is detached when the state of the NAS controller changes to Detached. (Click the Hardware tab→ Appliances→ Controller to display the state of the controller.)
