A media changer logical unit receives commands to move cartridges between various types in the element
address space. The element types are storage, import-export, data transfer, and medium transport. The
cartridge handling robotic subsystem, addressed as a medium transport element, moves cartridges within
a media changer. The media changer logical unit maintains an inventory of cartridges and the element
addresses. The media changer logical unit reports this inventory when requested as well as identifying the
element address assigned to different types of elements.
