A method for adding intelligence into the tape drive subsystems of a media storage library. The present invention improves overall system availability by enhancing existing control, monitoring, and diagnostic functionalities. As a result of inserting intelligence into the drive trays, certain control and monitoring functions traditionally performed by the main library controller may be performed locally at the drive trays. Since certain functions are performed locally at the drive trays, fewer connections are required between the tape drive trays and the main library controller. Also, the main library controller's performance is not degraded as the number of tape drives increases. The present invention also provides flexibility to the storage system since new features and functions may be added to the drive tray subsystem without the need to modify the base library cabling infrastructure.

Method for intelligent tape drive subsystem control and monitoring in a tape library

An invention for use with transporting media cartridges between a first storage library and a second storage library. The invention comprises at least two pass through ports connecting the first and second storage libraries for use in transporting media cartridges between the first and second storage libraries. The at least two pass through ports provide redundant operation of the multiple data storage library system to ensure media cartridge transportability between the first and second storage libraries in the event that one of the at least two pass through ports should become inactive.

A system, method, and product are disclosed for associating subcomponents with a storage library. A unique identifier is stored in a particular storage library. Each subcomponent that is a part of the particular storage library is then associated with the particular storage library by storing a copy of the unique identifier within each subcomponent. In order for a subcomponent to be usable by a particular storage library, the particular storage library's unique identifier must be stored within the subcomponent.

The present invention provides two redundant tape library controllers that mirror each other's function. A secondary controller can immediately take over from the primary controller if the primary unit fails or if a redundant path leading to the primary controller fails.
