This command starts the NFS mount daemon, and waits up to the default of 30 seconds for it to start. The mount daemon should not be already running, and other daemons have been started in the appropriate order.

Proper Shutdown Scenario

Shutting down an NFS server properly allows for all jobs to ®nish and all requests to be completed. In general, the order of actions required for the server to shutdown are the exact opposite of actions required for the server to startup:

1.The user ends the NLM daemon (QNFSNLMD).

2.The user ends the NSM daemon (QNFSNSMD). All locks that are held on local ®les by remote client applications are disengaged.

3.The user ends the mount daemon (QNFSMNTD). All remote client mounts of local ®le systems are disengaged.

4.The user ends the NFS server daemon (QNFSNFSD) or daemons.

5.The user ends the RPC binder (port mapper) daemon (QNFSRPCD).

If you specify *ALL for the SERVER parameter for the End Network File System Server (ENDNFSSVR) command will automatically end all the daemons in the correct order.

The order of client shutdown processes is generally the opposite from which the user starts the processes.

1.The user ends the NLM daemon, if it exists on the client. A single server NLM can operate for both the client and server.

2.The user ends the NSM daemon, if it exists on the client. A single server NSM can operate for both the client and server.

3.The user ends the block I/O daemon (QNFSBIOD) or daemons.

4.The RPC binder (port mapper) daemon is ended.

Shutdown Consideration

TCP/UDP Timeout Con¯ict

When ending the NFS server, the socket port closes. If the NFS server is immediately re-started, then the server may not be able to connect to the socket port. The underlying TCP/IP support on AS/400 renders this port unavailable for a short period. If you wait for a short period before re-starting the NFS server, then it will connect to the socket port as usual.

ENDNFSSVR (End Network File System Server) Command

Purpose

The End Network File System Server (ENDNFSSVR) command ends one or all of the Network File System (NFS) server daemons.

You should use SERVER(*ALL), which will end the daemons in the following order. (This order is the recommended order for ending the Network File System daemons.)

vThe network lock manager (NLM) daemon

vThe network status monitor (NSM) daemon

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.
