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

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

If any of the objects in the ®le system are in use, the command will return an error message to the user. Note that if any part of the ®le system hasitself been mounted over, then this ®le system cannot be unmounted until it is uncovered. If multiple ®le systems are mounted over the same mount point, the last to be mounted will be the ®rst to be removed.

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

vUNMOUNT

Restrictions

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

When you use the RMVMFS or UNMOUNT commands, you can specify many parameters and options:

vThe TYPE parameter on the ADDMFS command speci®es the type of ®le system being unmounted.

vThe MNTOVRDIR parameter on the ADDMFS command speci®es the path name of the directory that was mounted over (ªcoveredº) by a previous ADDMFS command.

vThe MFS parameter on the ADDMFS command speci®es the ®le system to be unmounted.

Note: This parameter can only be used to unmount a block special ®le (*BLKSF object) when you specify the *UDFS value in the TYPE parameter on the ADDMFS 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.
