13 Use the Connectivity Report page to verify connectivity between the FluidFS cluster and the Storage Center. The NAS controller
ports must show the status Up before you can complete the wizard. If you click Finish and the NAS controller ports do not have the
status Up, an error will be displayed.
• For iSCSI NAS appliances, when the Connectivity Report initially appears, iSCSI logins might still be occurring in the background,
causing some or all of the FluidFS cluster iSCSI initiators to show the status Not Found/Disconnected. If this happens, wait 30
seconds, then click Refresh to update the Connectivity Report. When the iSCSI logins are complete and the Connectivity Report
has been refreshed, the status for each
FluidFS cluster iSCSI initiator shows Up.
• For Fibre Channel NAS appliances, when the Connectivity Report initially appears, the FluidFS cluster HBAs show the status Not
Found/Disconnected. You must record the WWNs and manually update fabric zoning on the Fibre Channel switch. Then, click
Refresh to update the Connectivity Report. When the zoning is congured correctly and the Connectivity Report has been
refreshed, the status for each FluidFS cluster HBA shows Up.
14 Click Finish.
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 dierent NAS appliance.
1 In the Storage view, select a FluidFS cluster.
2 Click the Hardware tab.
3 In the Hardware view, expand Appliances and select the appliance ID.
4 Click Delete.
The Delete dialog box opens.
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 from 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 conguration changes are not allowed.
CAUTION
: Detach a NAS controller only under the direction of technical support.
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 Detach.
The Detach dialog box opens.
5 Click OK.
The Detach dialog box displays the progress of the detach process. If you close the dialog box, the process will continue to run in the
background.
