You put the directories you want to export in /etc/exports and then run 
exportfs.  A sample /etc/exports file might look like this:

# See exports(5) for a description.
# This file contains a list of all directories exported to other 
# computers.
# It is used by rpc.nfsd and rpc.mountd.
/export         10.100.47.0/255.255.255.0(rw,async,no_root_squash)

For more detail you can review the man page for exports (man exports) as 
suggested in the comments.

No, they will simply become inaccessible.  Upon umounting the remote 
directory they will become accessible again.

I haven't worked with this much, but the basics are simple enough.  Unix 
uses user ID numbers and group ID numbers to determine file ownership and 
permissions.  For example, my username is james and my userid is 1000.  My 
group name is users and my groupid is 100.  Thus files I own have a userid 
of 1000 and a groupid of 100.  On the iSeries I have the same username, 
but the userid number is different.  Thus to make my files be owned by me 
on the iSeries I need to map whatever my iSeries userid is to match my 
unix userid of 1000.
