Abstract
A tape library system for handling multi-volume tapes includes an automated tape system with at least one tape unit and a robotic tape handling system. The tape library system receives requests from at least one host for access to a specified tape volume in a specified tape unit. The tape library system includes a tape/library control unit that receives the request from the host computer and maps the specified tape volume to a tape cartridge. The TLCU determines if the tape cartridge is currently loaded in a tape unit and, if the tape cartridge is not loaded, commands the robotic tape handling system to load the cartridge into an available unit. The TLCU forms a virtual path between the host computer and the loaded tape unit. Data is then transferred between the loaded tape unit and the host computer. Thus, the host computer is presented with a virtual view of connection to the specified tape volume loaded in the specified tape unit.
