Disable Clustering

You may want to deactivate a node in preparation for deleting the node, or temporarily for maintenance. This procedure is meant to temporarily deactivate a node; the node will still appear in the management center device list. When a node becomes inactive, all data interfaces are shut down.

Procedure

Step 1

For the unit you want to disable, choose Devices > Device Management, click the More (more icon), and choose Disable Node Clustering.

If you disable clustering on the control node, one of the data nodes will become the new control node. Note that for centralized features, if you force a control node change, then all connections are dropped, and you have to re-establish the connections on the new control node. You cannot disable clustering on the control node if it is the only node in the cluster.

Step 2

Confirm that you want to disable clustering on the node.

The node will show (Disabled) next to its name in the Devices > Device Management list.

Step 3

To reenable clustering, see Rejoin the Cluster.
