Steps to take
Follow these steps:
- Determine whether the devices you use are supported. A list of supported I/O devices is in the topic about identifying I/O device requirements in z/OS Planning for Installation. If you have a question about support for any devices not listed, contact your IBM representative.
- Install replacement devices. Move data that is stored on unsupported devices to the supported devices. Detach unsupported devices from the system and delete their corresponding device definitions from the input/output definition file (IODF).
