Advanced HCD Coding for z/OS UK Classes & Lessons (IBM)

Also known as: ES98GBGB

About this class

The new concepts introduced with the z990 & z890 which significantly change the HCD process. It also covers the various topologies available with FICON channels, including cascaded FICON directors and FICON CTCs, and the use of Parallel Access Volumes (PAVs) with the IBM Enterprise Storage Server (ESS).

Who will the lesson benefit?

People responsible for maintaining the I/O configuration at their z/OS installation. This class is highly recommended as an immediate follow on for anyone who has just attended the basic HCD workshop (ES96GB).

What prerequisites are required

Basic knowledge of the use of HCD dialogs to create an I/O configuration and dynamically alter the I/O configuration. This can be gained by attending the ES96GB HCD class.
Hardware Configuration Definition for z/OS (ES96GB)

Contents of this class

The course cover topics, so that on completion, delegates will be able to:

Describe the major new functions of the z990
Explain the implications of multiple Logical Channel Subsystems
Configure a z990 to HCD including the use of the Chpid Mapping Tool
Describe the major differences between ESCON and FICON
Configure FICON point-to-point and Switched point-to-point configurations
Configure FICON using Cascaded FICON directors
Configure FICON CTCs
Describe the HCD configuration requirements of the IBM ESS subsystem
Understand rules for coding PAVs
Understand the benefits of PAVs.

Remarks

This 1 day class is normally scheduled immediately after the basic HCD workshop (ES96GB - 3 days) to allow those new to HCD to attend both classes in the single week. Attendees may wish to bring their z990 hardware configuration report file (.HWC or .CFR), in softcopy, to use with the chpid mapping tool.

Practical Work

The teaching sessions are accompanied by practical work.
