Repeating (copying) operating system configurations

You can copy operating systems within the same or to another IODF. When copying an operating system, the following related objects and connections are also copied:

• Devices defined for the operating system
• List of consoles (NIPCONs for MVS)
• EDTs including their esoterics and generic groups

In the following example, you copy an operating system to another IODF that already contains an operating system with the same ID that you specify in the repeat panel.

1. Make sure that the operating system in the target IODF has the same operating system type as the one in the source IODF.
2. On the Operating System Configuration List, copy the operating system using the Repeat (copy) OS configurations action from the context menu (or action code  r ). The Identify Target IODF panel is displayed.
3. Specify the IODF to which the selected operating system is to be copied. The default IODF is the IODF you are currently working with.
4. On the following Repeat Operating System Configuration panel, specify the required values and press the Enter key.

   If a device defined to the operating system already exists in the target IODF, HCD tries to map the device. If more than one device with the same type and number exist, HCD maps the device to the first device found. To avoid this sometimes erroneous mapping, specify a processor and partition on the Repeat Operating System Configuration panel in which the operating system is to be run. Refer to Migrating additional MVSCP or HCPRIO input data sets for detailed rules when a device is mapped.

   Console devices (NIPCONs for MVS) from the source operating system are copied to the beginning of the target’s console chain.

5. Because you copy an operating system that already exists in the target IODF, HCD displays a panel to confirm the merging of configuration data.
