I'm using DCFM 10.3.2 with Brocade DCX-4S, 4024 and 5480. If I look to the "Name Server" on any of these switches there are only a few names shown. Many attached devices (over 90%) are not show as "Member Of Alias" or "Member Of Zone". But there is an alias for any attached device in our SAN. And they are all member of a zone.
