Delete a NAS Appliance from the FluidFS Cluster
If an attempt to add a NAS appliance to a FluidFS cluster fails, the entry for the NAS appliance must be deleted from the FluidFS
cluster before you can reattempt to add the NAS appliance or add a dierent NAS appliance.
1. Click the Storage view and select a FluidFS cluster.
2. Click the Hardware tab.
3. In the Hardware tab navigation pane, expand Appliances, then select
NAS appliance ID
.
4. In the right pane, click Delete. The Delete dialog box appears.
5. Click OK.
Detaching, Attaching, and Replacing a NAS Controller
Use these procedures to replace a failed NAS controller.
Detach a NAS Controller
Detach a NAS controller only if the NAS controller needs to be replaced with a new NAS controller. After you detach a NAS
controller, it resets to its factory defaults and powers o, if possible. Otherwise, you must reinstall the FluidFS software to reset the
NAS
controller to its factory defaults.
About this task
Only one NAS controller can be detached in a NAS appliance at a time. Detaching a NAS controller disconnects client connections
while clients are being transferred to other NAS controllers. Clients will then automatically reconnect to the FluidFS cluster. 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.
CAUTION: Only detach a NAS controller under the direction of Dell Technical Support.
Steps
1. Click the Storage view and select a FluidFS cluster.
2. Click the Hardware tab.
3. In the Hardware tab navigation pane, expand Appliances→
NAS appliance ID
, then select
NAS controller ID
.
4. In the right pane, click Detach. The Detach dialog box appears.
5. Click OK. The progress of the detach process is displayed in the Detach dialog box. If you close the dialog box, the process will
continue to run in the background. The NAS
controller is detached when the NAS controller State changes to Detached (the
State is displayed at System tab→ Appliances→ Controller).

Attach a NAS Controller
Attach a new NAS controller when replacing an existing NAS controller. Once attached, the new NAS controller inherits the FluidFS
cluster conguration 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.
