Open System Services NFS Overview

Figure 2 Example of Remote Mount
The files and directories in the /usr/lib/src directory are now accessible on UNIX sysone
(through NFS) in the /usr/src directory.
NOTE: The OSS NFS directories and files you can access remotely from your NFS client are
managed by servers created by a system manager. Using the Subsystem Control Facility (SCF) on
a NonStop system, the system manager configures all servers, sets up NFS user IDs to control
access, and provides information about which directories (and subtree structures) you can mount.
At some installations, you (the NFS client user) might also be allowed to configure and manage
the OSS NFS subsystem. For instructions on performing these tasks, see the OSS NFS Management
and Operations Guide.
Unless you perform the system manager tasks, you do not need to know how to use SCF. However,
when you request a remote mount of a directory managed by an NFS server, you are accessing
a directory structure (or hierarchy) mounted locally on the NonStop system. To understand how
the system manager performs local mounts, it is useful to consider an example showing the SCF
commands that the system manager uses to create a mounted file hierarchy. The hierarchy in this
example is the same as the structure created in the previous example of UNIX sysone.
In Figure 3 (page 13), a system manager has configured three NFS servers (SD0, SD1, and SD2)
on a host NonStop system named \MAINSYS.
