Steps to take:

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).
