Is there a way to programmatically disable & remove a gateway node from the cluster.
Good morning. There is not a current way to disable a node programmatically only manual using the section "Deactivating a Cluster Node" in the online documentation (Deactivating a Cluster Node - CA API Gateway - 9.1 - CA Technologies Documentation ). Please create an Idea in the community on how you would like this functionality exposed.
