Using HCD for I/O Configuration

Objectives
On successful completion of this course, attendees will be able to:

• describe the role of HCD and IOCP/MVSCP
• use HCD panels to define a configuration comprising Processors, Logical Channel Subsystems, LPARs and EMIF, Channels (ESCON, FICON, OSA, CF links, Hipersockets and Routers), Control Units and I/O devices
• describe the constraints and issues in building an I/O configuration
• understand the concept of Logical Control units and Parallel Access Volumes
• define FICON and ESCON directors
• define the OS Configuration
• define Eligible Device Tables (esoterics, tokens and generics)
• define NIP consoles
• create validated work IODFs
• use the CHPID Mapping tool to include PCHIDs in the configuration
• create production IODFs
• plan for Dynamic I/O reconfigurations
• use HCD functions to maintain the IODFs
• migrate an IOCP

Who Should Attend
