8860ch13.fm Draft Document for Review September 23, 2019 1:06 am 13.3.3 Defining IQD devices to an OSCONFIG The OSCONFIG name is the part of an IODF that determines what devices a z/OS system  will have access to when it IPLs. Additionally the partition that the z/OS system is started in  also needs to have access to the CHPIDs that connect to the Control Units and Devices that  match in the OSCONFIG. The OSCONFIG also contains Esoterics device groups that are defined in EDTs within an  OSCONFIG. IQD definitions usually do not use Esoterics. The following are considerations for following are considerations for adding devices to an  OSCONFIG: To define IQD devices to an OSCONFIG, complete these steps: GLYPH<SM590000> Adding a device to an OSCONFIG does not necessarily mean that the z/OS system will  have access to that device. GLYPH<SM590000> The example will be adding the predefined IQD devices 0FA0-0FBF (IQD). 1. From the main HCD panel, select option 1.5. I/O Devices . 2. Scroll through the I/O Device List until you find the device number that you want to add to  the OSCONFIG, or in the command line enter  L 0FA0 . In our example, we use  0FA0 . 3. Enter  c  next to one or more Device numbers, and press  Enter . 4. HCD displays the Change Device Definition panel where you have the option to modify the  Control Unit that the devices are attached to (Figure 13-53). Press  Enter . Chapter 13.
