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.)
Attach a NAS Controller
Attach a new NAS controller when replacing an existing NAS controller. After it is attached, the new NAS controller inherits the
FluidFS cluster configuration settings of the existing NAS controller.
Prerequisites
Verify that the NAS controller being attached is in standby mode and powered on. A NAS controller is on and in standby mode if
the power LED is flashing green at around two flashes per second.
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 Attach.
The Attach dialog box opens.
5. Click OK.
The Attach dialog box displays the progress of the attach process . If you close the dialog box, the process will continue to
run in the background.
The NAS controller is attached when the state of the NAS controller changes to Formatted. (Click the System tab→
Appliances→ Controller to display the state of the controller.)
6. (Fibre Channel only) After the attach operation completes, record the new WWNs and manually update fabric zoning on the
Fibre Channel switch.
Replace a NAS Controller
In the event of a failure where a NAS controller cannot be brought back online (for example, a malfunctioning NAS controller),
you must remove the existing NAS controller from the FluidFS cluster and replace it with a different NAS controller.
Prerequisites
Before replacing the NAS controller ensure that the existing NAS controller is verified as failed by technical support.
About this task
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. Therefore, it is important to replace a failed NAS controller as soon as possible.
NOTE: Only replace a NAS controller under the direction of technical support.
Steps
1. Detach the existing NAS controller.
2. Ensure that all cables are labeled.
3. Disconnect all cables from the back of the existing NAS controller.
4. Remove the existing NAS controller from the NAS appliance chassis.
a. Press the controller release button to disengage the controller handle.
