https://<INSTANCE_NAME>.service-now.com/nav_to.do?uri=sys_properties.do?sys_id=60d2b6f48f240300f4e30b5437bdee17

Resolution

Set sys_properties "glide.discovery.sensors.netapp_native_cluster_mode" value to 'true'. 

Additional Information

It seems if the instance was provisioned starting Kingston version, the "glide.discovery.sensors.netapp_native_cluster_mode" value by default is 'true'. If the instance was upgraded to Kingston from earlier version, the value is 'false'.

Under Classifier Probe: HorizontalDiscoveryProbe-Horizontal Patt (https://<INSTANCE>.service-now.com/nav_to.do?uri=discovery_classifier_probe.do?sys_id=f9f0a1909f5803003f2492ec757fcfdb )

there is a condition script:
