mount command

Purpose

Makes a file system available for use.

Syntax

mount [[[Node:]Directory] Directory]

mount -cd Device Directory

mount -nfsvers version [[[Node:]Directory] Directory]

Description

The mount command instructs the operating system to make a file system available for use at a specified location (the mount point). The mount command mounts a file system that is expressed as a directory by using the Node:Directory parameter on the directory specified by the Directory parameter. After the mount command has finished, the directory that is specified becomes the root directory of the newly mounted file system.

If you enter the mount command without flags, the command displays the following information for the mounted file systems:

The node (if the mount is remote)
The object mounted
The mount point
The virtual-file-system type
The time mounted
Any mount options

The /mnt directory can be used as a local mount point, or you can create a directory by using the mkdir command. Any directories that are created with the mkdir command must be a sub-directory of your home directory.

Flags

Flag name	Description
-cd	Specifies the cd device name on which to mount.
-nfsvers	Starts Network File System (NFS) version 4 mounts on the Virtual I/O Server (VIOS).

Exit Status

See Exit status for Virtual I/O Server commands.

Examples

To list the mounted file systems, enter:

mount

This command produces output similar to the following:

node    mounted  	         mounted over   vfs      date           options

vios4   /home/padmin/tstvf4   /mnt           nfs4     Apr 06 16:48   vers=4

For each file system, the mount command lists the node name, the device name, the name under which it is mounted, the virtual-file-system type, the date and time it was mounted, and its options.

To mount the remote directory on to a local directory, enter:
```
mount testsys3:/test /mnt
```
This command mounts the /test directory that is located on testsys3 onto the local /mnt directory.
To mount the NFSv4 on a local directory, enter:
```
mount –nfsvers 4 testsys3:/test /mnt
```
