OS/390 Hardware Configuration Definition (HCD) and Dynamic I/O

Duration: 3 Days

Overview:

Learn to work with the Hardware Configuration Definition (HCD) function for OS/390, and to plan and initiate dynamic reconfiguration of your OS/390 hardware environment. Learn to use the HCD dialogs of OS/390 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 an OS/390 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.

Who Should Take This Course:

Individuals responsible for maintaining the I/O configuration contained in the I/O Definition Files (IODF) and IOCDS for their OS/390 installation.

What You Are Taught:

• Create an IODF work file from scratch
• Build a production IODF using a work IODF
  
• Build an appropriate LOADxx Parmlib member for Initial Program Loader (IPL)
• Initiate dynamic reconfiguration changes
• Create configuration reports using HCD
• Describe HCD migration considerations
• Describe how HCD and I/O Operations (formerly Enterprise System Connection Manager (ESCM)) are used together
