Re-enable disabled cluster nodes
You can re-enable nodes in a cluster that you have temporarily disabled.
Before you begin
Note: If you reintroduce a disabled node that has a working configuration, the node must receive
the heartbeat traffic from other nodes and accept it based on certificates. Otherwise, the node considers itself the only available cluster member and goes online. Cluster nodes that
do not communicate with each other can prevent the whole cluster from processing traffic.
When a Engine Cluster, IPS Cluster, Layer 2 Engine Cluster, or Master Engine node has been disabled, its configuration is typically made obsolete by policy installations done on the other cluster nodes. Having an obsolete configuration prevents the node from operating normally and might in some cases disturb the operation of the whole cluster.
