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.

AS/400E specifications

The IBM AS/400E, now more commonly known as IBM i, is a robust and versatile midrange server that has been designed to provide a comprehensive computing solution for businesses of all sizes. First introduced in the late 1980s, the AS/400 series has undergone multiple enhancements and rebranding, with the AS/400E being one of the notable iterations. This powerful platform is closely associated with IBM's commitment to reliability, scalability, and integrated business solutions.

One of the main features of the AS/400E is its highly integrated architecture that combines hardware and software into a cohesive system. This integration allows for seamless operations, reducing the complexity typically associated with managing disparate systems. The system is powered by IBM's proprietary OS/400 operating system, which has evolved into IBM i, featuring advanced capabilities like object-oriented programming, integrated database management, and security features that are essential for enterprise environments.

A key characteristic of the AS/400E is its robust database support, primarily through the use of DB2 for i. This integrated database management system enables efficient data handling and retrieval, facilitating real-time business analytics and reporting. Furthermore, the platform supports a variety of programming languages, including RPG, COBOL, and Java, making it flexible for developers who require diverse tools for application development.

The AS/400E is also known for its exceptional reliability and uptime, making it a preferred choice for critical business applications in industries such as finance, healthcare, and manufacturing. This reliability is backed by advanced error detection and correction mechanisms, as well as redundancy features that help prevent data loss and minimize downtime.

In terms of scalability, the AS/400E can effortlessly expand to accommodate growing business demands. Organizations can increase processing power by adding more resources without significant disruption. This scalability, combined with the system’s built-in virtualization capabilities, allows businesses to optimize resource usage and streamline operations.

Security is another defining feature of the AS/400E. The platform incorporates various layers of security measures, including user authentication, encryption, and comprehensive auditing capabilities, ensuring that sensitive business data is protected against unauthorized access.

Overall, the IBM AS/400E remains a powerful tool in the enterprise computing landscape, providing businesses with an integrated, reliable, and secure solution for their technological needs. Its enduring popularity is a testament to its capability to evolve with changing business requirements while maintaining its core attributes of high performance and stability.
