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 conguration settings of the existing NAS controller.
Prerequisite
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 ashing green at around two ashes 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 dierent NAS controller.
Prerequisite
Before replacing the NAS controller ensure that the existing NAS controller is veried 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 conguration 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.
b Push the controller handle down until the controller disengages from the appliance.
c Use the controller handle to pull the controller out of the appliance.
5 Insert the new NAS controller in the NAS appliance chassis.
a Ensure that the controller cover is closed.
b Align the controller with the appropriate slot in the appliance.
c Push the controller into the appliance until the controller seats into place.
