Disable cluster nodes temporarily

Disabling a cluster node allows continued management of the other cluster members if one node goes out of operation.

Before you begin

Turn off the cluster node that you want to disable and disconnect the network cables.

You can disable nodes in Firewall Clusters, IPS Clusters, Layer 2 Firewall Clusters, or Master NGFW Engines. When you disable a node, you can physically remove it from the cluster without removing its definition from the system.

Disabling a node indicates to the other nodes and the Management Server that it is not necessary to try to contact it. Disabling a node prevents unnecessary communication attempts, alerts, and test failures. Disabling a node also allows policy installations on the other nodes when one node is shut down or malfunctions. No commands can be sent to a disabled node and no monitoring information is available for it.
