Assign or Unassign a Client to a NAS Controller
You can permanently assign one or more clients to a particular NAS controller. For effective load balancing, do not manually
assign clients to NAS controllers, unless specifically directed to do so by Dell Technical Support. Assigning a client to a NAS
controller disconnects the client’s connection. Clients will then automatically reconnect to the assigned NAS controller.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Cluster Connectivity.
4. Click the Clients and Routers tab and select a client or router IP.
5. In the Filters panel, click Pin. The Pin Client to NAS Controller dialog box opens.
6. To assign a client to a NAS controller:
a. From the Pin Client to drop-down list, select the NAS controller to which to assign the client.
b. From the Use Client Interface drop-down list, select the client interface on the NAS controller to which to assign the
client.
7. 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.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Cluster Connectivity.
4. In the Filters panel, select a client and then click Move. The Move Client to NAS Controller dialog box opens.
5. From the Move Client to drop-down list, 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.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Cluster Connectivity.
4. In the Filters panel, click Failback. The Failback Clients dialog box opens.
5. Click OK.
Rebalance Client Connections Across NAS Controllers
Rebalancing client connections evenly distributes connections across all the available NAS controllers.
