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.
1. Change the FluidFS cluster operation mode to No Service.
For more information on changing the FluidFS cluster operation mode, see Changing the Operation
Mode
2. To shut down the NAS controllers, press and release the recessed power button at the back of each
NAS controller.
NOTE: Do not press and hold the power button down for several seconds. Pressing and holding
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.
NOTE: Before turning on the system, ensure that all cables are connected, and all components are
connected to a power source.
1. If previously shutdown, turn the MD system(s) back on before starting the FluidFS cluster.
2. Press and release the recessed power button at the back of each NAS controller to turn on the NAS
controllers.
3. Change the FluidFS cluster operation mode to Normal.
For more information on changing the FluidFS cluster operation mode, see Changing the Operation
Mode
Rebooting a NAS Controller
Only one NAS controller can be rebooted in a NAS appliance at a time. Rebooting a NAS controller
disconnects client connections while clients are being transferred to other NAS controllers. Clients
automatically reconnect to the FluidFS cluster.
1. Click the Hardware tab on the left.
2. Click the NAS Appliances tab on the top.
3. In the Overview pane, click in the row of the NAS appliance you want to reboot.
