srvctl config scan also showed just two. And if your dns is configured properly, it should show all 3 entries. At least it does on Solaris and on oel. When does the third entry not show? does crsctl add the entry to the endpoints_listener.ora file? The last time I checked, Oracle usually said dont use crsctl for this kind of stuff except as a last resort.
