The invention provides a library apparatus wherein provisions are made to be able to continue the entire operation of the library apparatus uninterrupted if a failure occurs in any one of the constituent elements of the library apparatus, with further provisions made to be able to identify the source of the failure. The library apparatus 1 comprises library controllers Lct 1 and Lct 2 configured in a redundant configuration and drive command paths P 1 and P 2 configured in a redundant configuration, wherein a library controller port on the library controller Lctl is configured redundantly by duplicating a port 14 with a port 15 , the ports 14 and 15 being connected to the redundantly configured drive command paths P 1 and P 2, respectively, and a library controller port on the library controller Lct 2 is configured redundantly by duplicating a port 24 with a port 25, the ports 24 and 25 being connected to the redundantly configured drive command paths P 1 and P 2, respectively.
