Migrating the OS Configuration

To define the I/O configuration to the software, you can either postpone that step until you have generated the HCM configuration file from the IODF. Then, use HCM to define the VM operating system and assign the devices to this operating system. Or, you can migrate the actual operating system I/O configuration settings in terms of the RDEV control blocks into the IODF.

Migration of the RDEV control blocks can be done only from a z/VM system. For this purpose, you first must generate a file which contains the binary image of the RDEV control blocks of your z/VM system. In a second step, migrate this file into the IODF. (see Step 4. Migrate Your Operating System from an RDEV List).

You may have to complete the definition afterwards in the IODF for the devices that are offline and cannot be sensed by z/VM.
