You can change the status of an NFS directory to shared or unshared. When you change the status of an NFS directory to unshared, any remote file system that has mounted the NFS directory can no longer access the files or subdirectories in the file system.
Note - Changing the status of an NFS directory to unshared does not permanently disable the sharing of the NFS directory. Instead, it changes the status of the NFS directory to inactive. To permanently disable sharing, you must remove the NFS directory. For more information, see How to Remove an NFS Directory.
To change the status of an NFS directory:
The NFS Shared Resources page is displayed.
The directory is redisplayed with the newly changed status value in its Current Status column.
