Hardware configuration definitions

As with all channel-attached devices, you must define an IBM Open Systems Adapter (OSA) in the input/output configuration data set (IOCDS) with a channel path, a control unit, and input/output (I/O) devices. This chapter takes you through the steps to define OSA to the IBM System z environment by using the IBM z/OS Hardware Configuration Definition (HCD) tool. To simplify the configuration process of the environment, ...
