bradje1,
When 3 IPs are discovered, does the same device appear in both RAC and Unknown group (Manage -> Devices) ?
Are the IP Addresses under "NIC Information" for a device under RAC and Unknown group match ?
Can you try discovering only 1 IP and share the results ? Does it create one device under "RAC" group or creates devices under both RAC and Unknown group ?
Thanks,
Raj Shresta
