What exactly does intelligent mapping mean ?

I have a volume on my primary NW65 server called ARCHIVE:
I also have a volume called ARCHIVE: on another NW65 server on the same network.

I have an entry in my system login script which reads:


Assuming users have correct rights to both volumes, will they ALWAYS map R: to the primary server ARCHIVE volume so long as it is available, and ONLY map R: to the other ARCHIVE volume if the primary server volume becomes unavailable ?

Is this what intelligent mapping means ?
