Overview

Learn to work with the Hardware Configuration Definition (HCD) function for z/OS, and to plan and initiate dynamic reconfiguration of your zSeries hardware environment. Learn to use the HCD dialogs of z/OS to create an Input/Output (I/O) configuration and dynamically alter the I/O configuration. Learn about the creation of an I/O Configuration Dataset (IOCDS) and various reports that HCD can build. Use a z/OS system to reinforce lecture topics and to practice working with the HCD dialogs. Hands-on lab projects may be done in teams depending on the number of attendees and location.

Audience

This course is for people who are responsible for maintaining the I/O configuration contained in the input/output data files (IODFs) and input/output configuration data sets (IOCDs) at their z/OS installation.

Prerequisites

You should have:

• A basic knowledge of z/OS and I/O configuration

This knowledge can be developed on the job, or by taking Fundamental System Skills in z/OS (ES10A).

Objective

• Describe new zSeries processor technology
• Code new zSeries processors (z9 to z196)
• Code FICON channels and FICON CTCs
• Code Coupling Facilities (CF) and CF links
• Code cascaded FICON Directors
• Create an IODF work file on a z processor from scratch
• Use CHPID mapping tool to create a validated work IODF
• Use work IODF and create a production IODF
• Perform Dynamic I/O changes on a real z/OS system
• Build a LOADxx parmlib member for initial program load (IPL)
• View configuration graphically
• Create appropriate configuration reports
