Assign or Unassign a Client to a NAS Controller
You can permanently assign one or more clients to a particular NAS controller. For eective load balancing, do not manually assign
clients to NAS
controllers, unless specically directed to do so by your technical support representative. Assigning a client to a NAS
controller disconnects the client’s connection. Clients will then automatically reconnect to the assigned NAS controller.
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab.
3. In the File System tab navigation pane, select Client Activity.
4. Click the Clients tab and select a Client or Router IP.
5. Click Pin Client to NAS Controller. The Pin Client to NAS Controller dialog box appears.
• To unassign a client to a NAS controller, clear the Pin check box.
• To assign a client to a NAS controller, select the Pin check box.
1. From the Pin Client to drop-down menu, select the NAS controller to which to assign the client.
2. From the Use Client Interface drop-down menu, select the client interface on the NAS controller to which to assign
the client.
6. Click OK.
Manually Migrate Clients to Another NAS Controller
You can manually migrate clients between NAS controllers if, for example, the network load on the NAS controllers is not balanced.
Migrating a client to another NAS
controller disconnects the client’s connection. Clients will then automatically reconnect to the NAS
controller to which they were migrated.
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab.
3. In the File System tab navigation pane, select Client Activity.
4. Select a client and click Move Client to NAS Controller. The Move Client to NAS Controller dialog box appears.
5. From the Move Client to drop-down menu, select the NAS controller to which to migrate the client.
6. Click OK.
Fail Back Clients to Their Assigned NAS Controller
You must fail back client connections to their original NAS controller when a NAS controller that was down becomes available. Failing
back client connections disconnects only the client connections that failed over due to the original NAS
controller failure. Those
clients will then automatically reconnect to the assigned NAS controller.
1. Click the Storage view and select a FluidFS cluster.
2. Click the File System tab.
3. In the File System tab navigation pane, select Client Activity.
4. In the right pane, click Failback Clients. The Failback Clients dialog box appears.
5. Click OK.
Rebalance Client Connections Across NAS Controllers
Rebalancing client connections evenly distributes connections across all the available NAS controllers.
About this task
You must rebalance client connections in the following scenarios:
• After FluidFS cluster hardware changes (for example, adding a NAS appliance)
• When a NAS controller that was down becomes available
Rebalancing client connections disconnects all client connections. Clients will then automatically reconnect to the FluidFS cluster.
