You can use a nonqualified tape drive (one that is not on the list of qualified tape drives) on a storage system if it can emulate a qualified tape drive. It is then treated as though it were a qualified tape drive.
For a nonqualified tape drive to emulate a qualified tape drive, you must enter the nonqualified tape drive information in the /etc/cloned_tapes file. This file enables the storage system to register the drive as a clone of a qualified drive.
