I/O Definitions (IODF)Device definitions are necessary for two reasons

Only defined devices are know to the Channelsubsystem

Only defined devices are know to the OS IODF are made using HCD IODF are stored in IODF datasets IODF datasets are used during IPL to define the

devices to OS, by creating UCB (Unit Control Blocks)

IODF is converted into IOCDS (I/O control datasets)for use during POR.

3 types of Profiles exists. LOAD IMAGE RESET

The Load profile defines parameters for theprocessing unit, load device address, and associatedparameters.

The Reset profile defines the IOCDS, the parametersto power-up and power-on reset, and also identifies

the Load or Image profiles that will be used. The Image profile defines parameters to control the

activation of logical partitions.

Specify System Parameter Double click the IMAGES in WORK area and select

the any one of the LPAR. Double click the OPERATING SYSTEM MESSAGES in

TASK area. This will ask for system parameters Enter R 00Then JES will come up before which we need to

specify the JES2 parameters( whether Cold/warm

start.)Repeat the above steps for each LPAR.
