How this works depends on your tape drive. Some drives present
themselves as an array of drives, and the nomenclature above works, but
many do not. I have an HP drive that occupies a sinlge SCSI ID, but the
drive and changer mechanism are separately addressable LUNs. You should
look into mtx or chg-scsi, which support several models of autochanger.
