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 dierent NAS controller.
Prerequisite
Before replacing the NAS controller ensure that the existing NAS controller is veried as failed by Dell 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 conguration 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 Dell 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.
d. Push the handle toward the front of the appliance until it locks.
6. Reconnect all cables to the same ports on the new NAS controller. The NAS controller automatically powers on if at least one
power supply is connected to a power source.
7. Attach the new NAS controller.
