Abstract: A converter is utilized with at least one implicit addressing sequential media device to simulate explicit addressing sequential media device performance from the perspective of host applications. Responsive to receiving explicit addressing read/write commands from the host application, the converter converts the explicit addressing read/write commands into implicit addressing read/write commands and passes the implicit addressing read/write commands through to the device. Optionally, responsive to device capability queries from a host application, the converter reports that the device utilizes explicit addressing. As another option, responsive to receiving commands other than explicit addressing read/write commands from the application host, the converter examines the commands to monitor sequential media address, and relays the commands to the device substantially free of any modification.

Abstract: Addressing failure is handled in a nodal system of processor nodes, which comprise at least one processor and at least one interface to a network. Upon detection of a node address failure of a processor node for the network, such as lack of a node address, or presence of a duplicate address, the processor node is disabled from the network, thereby temporarily failing the processor node so that the system remains operational. An alternate node address stored in nonvolatile memory may be selected that avoids the node address failure.

Abstract: In an automated data storage library having a plurality of multi-cartridge deep slot cells, each configured to store a plurality of data storage cartridges arranged in sequential order of tiers from front to rear, and having accessor(s) configured to selectively extract, place and transport cartridges with respect to the cells; operating the accessor(s) to selectively extract, place and transport cartridges with respect to the cells and with respect to other elements of the library. If all tiers of the selected cells except the rearmost tier are full, added cartridges are placed to fill the rearmost tier of an evenly spread selection of the cells.

Abstract: A data storage library features multipurpose slots each configured to receive a media drive (operable to read/write data from/to media removably loaded into the media drive) a command relay port (operable to convey media transport signals from a host to a shared robotic media transport device), or various other modules. The robotic device is programmed to recognize whether each slot is empty or whether it is filled with a component such as a media drive or a command relay port, and to thereafter communicate with the occupant appropriately.
