## 11.1 Defining more I/O using HCD 

When defining new I/O components in an IODF, certain definitions like OSCONFIGs, Partitions, FICON Switches, Control Units, and Devices need to be made up front. After these items have been defined, the connections can be made: 

GLYPH<SM590000> Defining an additional OSCONFIG 

GLYPH<SM590000> Defining additional OS LPARs in a CSS 

The following I/O definitions use HCD to demonstrate the examples. The examples in this section continue the work example that was created in the previous sections (for example, ITSO1.IODF66.WORK ). 

## 11.2 OSCONFIGs and Logical Partition definitions 

This section covers defining Operating System Configurations, Logical Partitions, and FICON Switches.
