Hardware Configuration and Definition (HCD) for z/OS

( Duration: 4 Days )

In Hardware Configuration and Definition (HCD) for z/OS training course, attendees will learn to work with the Hardware Configuration Definition (HCD) function for z/OS, and to plan and initiate dynamic reconfiguration of zSeries hardware environment. They learn to use the HCD dialogs of z/OS to create an Input/Output (I/O) configuration and dynamically alter the I/O configuration. They learn about the creation of an I/O Configuration Dataset (IOCDS) and various reports that HCD can build.

By attending Hardware Configuration and Definition (HCD) for z/OS workshop, attendees will learn to:

  • 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

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

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.
