In some cases, iSeries Navigator will try to communicate with all of the nodes in the cluster. This depends on the state of your cluster. When iSeries Navigator needs to communicate with a node, it will first search the existing signon cache in iSeries Navigator to try to find an existing open connection. If it does not find an existing connection, it will then ask the user to sign on. If you cancel the signon window, iSeries Navigator will make an attempt to allow the user to do cluster operations. Some operations may not be possible if iSeries Navigator can’t communicate with the nodes.
