Seminar abstract and Outline
Audience:
This two-day seminar is designed for system programmers, operations staff and management personnel who are directly or indirectly involved with all aspects of hardware configuration using IBM's Hardware Configuration Definition (HCD) product.
Seminar Instructor:
Phil Riley
Seminar Abstract:
The seminar presents students with an overview of the HCD environment together with the methodology for navigating through the HCD dialog panels. Students learn how to create new configurations within an I/O Definition File (IODF), both from a hardware and software perspective, including coupling facility connectivity. Unique configuration requirements for IBM's latest processors are described.
Power-on-Reset and IPL considerations for the use of the IODF are explained. HCD support of IOCP and MVSCP/HCPRIO is discussed, with respect to both migration of this data into an IODF, and the functionality and requirement to rebuild such statements from an IODF definition.
An overview of the various HCD utility functions is presented, including the capability of printing configuration reports and comparing configurations to confirm changed data. In addition, students are introduced to the concept of dynamically activating a new configuration without the need for a system IPL or a Power-on-Reset.
Note: Although ESCON and FICON switch configuration concepts are mentioned in the course material, IOCP and HCD specific details plus practical application through the use of labs is reserved for the associated two-and-a-half-day FICON Configuration Workshop seminar.
Lecture material is reinforced with the use of lab exercises.
Prerequisites:
To fully benefit from this seminar, students should possess knowledge of hardware components. A basic understanding of the I/O Configuration Program (IOCP) process is helpful but not mandatory.
Seminar Objectives:
In this seminar, students will learn how to:
- Use the HCD dialog panels to create a complete hardware and software configuration
- Configure multiple logical channel subsystems where necessary
- Configure and connect coupling facility links to one or more processors
- Generate IOCP statements from HCD and re-migrate back to HCD
- Generate and interpret configuration item and comparison reports
- Successfully perform a dynamic configuration change
- Reference a required software configuration during an IPL procedure
