The Cluster Edition adds the sysinstances fake table, which reports on the state of the instances. sysinstances includes a row for each instance defined in the cluster configuration.
Although sysinstances is a fake table, it is not impacted by the setting of set system_view, and always returns a row for each instance, regardless of the system_view setting.
