Mount Points

Mount points mark the area of the local client and remote server namespaces

where users have mounted exported ®le systems. Mount points show where the ®le

system has been mounted from on the server and show where it is mounted to on

the client.

For example, the system exports the /home/consults directory from TULAB1 and

mounts it over the /test directory on a remote client. The mount point on the client

is /test. The old directory, /test, and its contents are covered up, and it becomes a

window into the namespace of the server, TULAB1. To see which remote ®le

system corresponds with a mount point or path, use the DSPMFSINF command. For

example:

DSPMFSINF OBJ(©/test©)

For more information on this command, see ªDSPMFSINF (Display Mounted File

System Information) Commandº on page 50.

How Do I Mount File Systems?

Users make remote server ®le systems accessible to the local namespace using the

MOUNT and ADDMFS (Add Mounted File System) CL commands. The UNMOUNT

and RMVMFS (Remove Mounted File System) commands will remove a mounted

®le system from the namespace. The DSPMFSINF (Display Mounted File System

Information) command will provide information about a mounted ®le system. You

can also reach these commands through a menu. Type GO CMDMFS (Go to the

Mounted File System Commands menu) at any command line.

Before attempting to mount NFS ®le systems, you need to verify that the correct

TCP/IP con®guration exists on your AS/400 system. Please refer to ªCon®guring

TCP/IPº on page 65 for more information.

ADDMFS (Add Mounted File System) Command

Purpose

The Add Mounted File System (ADDMFS) command makes the objects in a ®le system accessible to the integrated ®le system name space. The ®le system to be mounted can be either:

1.a user de®ned ®le system (*UDFS) on the local system

2.a remote ®le system accessed via a local Network File System client (*NFS)

3.a local or remote NetWare ®le system (*NETWARE).

The directory that is the destination for the mount must exist. After completion of the mount, the contents of this directory will be ªcovered upº and rendered inaccessible to the integrated ®le system namespace.

Users can issue this command by using the following alternative command name:

vMOUNT

Restrictions:

1. You must have *IOSYSCFG special authority to use this command.
