Shutting Down and Restarting NAS Controllers
In some cases, you must temporarily shut down a FluidFS cluster or reboot a NAS controller.
Shutting Down the FluidFS Cluster
In some cases, you might need to temporarily shut down all NAS controllers in a FluidFS cluster. For
example, you might need to do this if you are moving the NAS hardware to a different location. When a
FluidFS cluster is shut down, NAS volume data is no longer available to clients and clients are
disconnected.
NOTE: Dell recommends scheduling a maintenance window and informing clients that the
resources hosted by the FluidFS cluster is unavailable.

NAS controller.

the power button down for several seconds does not shut down the NAS controllers.
Starting Up the FluidFS Cluster
Start up a FluidFS cluster to resume operation after shutting down all NAS controllers in a FluidFS cluster.

connected to a power source.
