  1. Open the Dashboard in the Policy Manager and select the [Cluster Status] tab.
  2. In the Gateway Status list, right-click on the inactive node and then select
    Delete Node
    . (Note that only inactive nodes can be deleted.) The node will reappear in the list once it is active again.
Software Gateways
To temporarily deactivate a Gateway node from a cluster:
  1. Stop the Gateway.
  2. Note the name of the deactivated cluster node. Follow the instructions under "Delete a Node" in "Dashboard - Cluster Status".
A deleted node is not permanently removed from the Gateway cluster. When you want to reactivate the deleted node, stop and restart the applicable Gateway to once again view the node in the Policy Manager’s dashboard. You cannot delete an active node nor delete an active Gateway service.
