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
You can disable nodes in Engine Clusters, IPS Clusters, Layer 2 Engine Clusters, or Master 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.
