The VLDB contains IP addresses not names.  When you remove by name, the
name is resolved into an IP address.   There is no knowledge of interfaces.

You can use vos delentry to remove the entries from the VLDB without
moving the volumes and then use vos syncvldb to generate new entries
for the deleted volumes.

Of course, only do this after you have NetRestricted the file server.
Then you can remove the extraneous server entries from the VLDB.
