Running the Device Support Facilities Program

The Device Support Facilities Program (ICKDSF) is provided with z/VM®. It normally resides on the CMS system volume.

You can use it to perform various operations on direct access storage devices (DASD). For example, you can use ICKDSF to inspect a DASD volume for defective tracks, assign alternate tracks if defective ones are encountered, change a volume label or owner ID, or initialize a DASD volume so that it can be used in an operating system environment.

To perform these operations, see the detailed descriptions in Device Support Facilities User's Guide and Reference.
