Restoring Configuration to Multi Node Environment
If you are restoring to a multi node cluster, you can either replace only one node in the (still-healthy)
cluster or replace multiple nodes in the cluster.
Restoring Configuration to a Single Node in a Cluster
Follow these steps to replace the configuration of a single node in a cluster.
1. If the node that you want to replace is still functioning, follow these steps to remove the node.
a) Choose a controller that will remain in the cluster.
b) Log on to that controller's web interface as an administrator.
c) Go to Configuration > System.
d) On the sidebar, click Cluster Planes.
e) Locate the node that you want to replace.
f) Under the Actions column, click the delete button to remove the node from the cluster.
2. If the node that you want to replace is out of service, you will need to shut down the node
before you can replace it. Follow these steps.
a) On the node that you want to replace, log on to the CLI as a system administrator.
b) Run the enable command to enable privileged mode on the CLI.
ruckus> enable
Password: ********
ruckus#
c) (Optional) Back up the current controller system.
See Step 2: Back Up the Cluster from the Controller CLI on page 452.
d) On the node that you want to replace, run the shutdown command.
ruckus# shutdown
e) Log on to the controller web interface as a system administrator.
f) Go to Configuration > System.
g) On the sidebar, click Cluster Planes.
h) Locate the node that you want to replace,
i) Under the Actions column, click the delete button to remove the node from the cluster.
j) Set up the node as a new controller, and then join the existing cluster. For step by step
instructions, see the SmartCell 200 Getting Started Guide.
You have completed restoring configuration to a single node in the cluster.
Restoring Configuration to Multiple Nodes in a Cluster
If the cluster itself is not healthy anymore or if multiple nodes need to replaced, you must you
must factory reset all remaining nodes to ensure that configuration restore to the cluster will be
successful.
Follow the steps to restore the configuration to multiple nodes in a cluster.
1. Prepare the new controller nodes and factory reset all of the existing nodes in the cluster.
2. Complete the setup procedure for one of the controller nodes.
