An intelligent bus listening device, and a method which may be implemented as a computer program product, listens to SCSI commands on a first SCSI bus of a SCSI system via a listening connection to the first SCSI bus. The listening device is separately coupled via an interface to a second bus for communicating commands onto the second bus. A processor is coupled to the listening connection and to the second bus interface, the processor receiving the first commands from the first SCSI bus, converting the first commands to second commands related to the first commands, and providing the second commands to the second bus interface. In a SCSI library that accesses media from storage shelves with an autochanger in response to access commands from hosts, the intelligent bus listening device decouples the first SCSI bus from the autochanger, listens to commands on the first SCSI bus, and converts the access commands to a more efficient set of movement commands, and supplies the movement commands on a separate second bus for the autochanger.
