Before a NFS filesystem can be accessed by a NFS client, the NFS server must export the filesystem. The filesystem can be a volume (/vol/vol1), a qtree (/vol/vol1/qtree) or a directory (/vol/vol1/qtree/dir1).
Before the filesystem can be accessed,
1. it must be created: vol create vol1 10g
2. a entry must be added to the /etc/exports file on the filer's root volume. The entry might look like: /vol/vol1 -rw=host1:host2,root=host1
3. then the "exportfs" command must be run on the filer: exportfs -a
Now the NFS client host can mount the filesystem: host1# mount filer1:/vol/vol1 /mnt
You can read more by running the "man" command on the filer: man exportfs
