摘要： According to one embodiment of the present invention, a controller that partitions a media library for multiple host applications can, for each partition, assign a base element address for an element type and associate physical element addresses for elements of an element type with an index value. For a partition, the logical element address corresponding to a physical element address for an element can be determined by adding the index number associated with the physical element address to the base element address for that element type. The physical element address corresponding to a logical element address for an element can be determined by subtracting the base element address for the element type from the logical element address for the element. The result of subtracting the base element address from the logical element address is an index value for which the associated physical element address can be found.

摘要： Embodiments of the present invention provide a method and system for handling status commands directed to a partitioned media library. A controller (e.g., storage router or other device) that controls access to the physical media library can receive a status command and determine whether it should respond to the status command without passing the command to the media changer of the physical media library. If the controller should respond, the controller can construct a response and send it to the issuing host application. Otherwise the controller can pass the command to the media changer of the physical media library.

摘要： A system and method of media library access that utilizes distributed mapping of media library partitions. A first controller can be connected to a data transport element of a media library and a second controller can be connected to a media changer of the media library. The first controller can maintain a media library partition representing a portion of the media library, receive a command from a host application based on the media library partition and forward the command to the second controller. The first controller can further translate logical addresses referenced in the command to physical addresses before forwarding the command to the second controller. The second controller can receive the command from the first controller and forward the command to the media changer. The second controller can also prioritize the command on using a FIFO or other prioritization scheme.

摘要： Embodiments of the present invention provide systems and methods for handling commands requesting movement of a data storage medium (magnetic tape, optical disk, or other medium) from a source media library to a destination media library using a pass through port. Prior to issuing commands requesting movement of the data storage medium from a source location to the pass through port and from the pass through port to a destination location, embodiments of the present invention can check the status of various locations (e.g., the destination location or pass through port) to determine if the movement requested in the original command can be completed successfully. Another embodiment of the present invention can maintain reservation flags for pass through ports so that the status of particular pass through ports can be determined and an available pass through port selected.
