Cluster nodes that have been generated for future use in UTM, but for which the corresponding applications are not (yet) currently being run, can be deactivated in WebAdmin. This is done by executing the 'Deactivate Node Application' function for a node application. Any node application deactivated using this function is indicated by a special icon ( 
) in the user interface. The primary page of a node application that has been deactivated in this way contains only the 'Activate Node Application' function. It is therefore not possible to access the objects and properties of these node applications. WebAdmin does not take account of deactivated node applications for cluster functions (check availability, fetch objects, etc.).
Deactivated node applications can be reactivated using the 'Activate Node Application' function.
