An automated data library system employs a calibration sensor, the fiducial target and a controller in electrical communication with the calibration sensor to create a calibration sensor pixel image of a calibration area surrounding an expected location of the fiducial target within the automated data storage library by executing one or more vertical calibration sensor scans and/or one or more horizontal calibration sensor scans of the calibration area, and monitoring an output of the calibration sensor scans at defined position intervals. The expected location of the fiducial target can be on a data storage drive of the library or a storage shelf of the library. The controller can execute a debugging procedure, a diagnostic test and/or an error recovery procedure based on the calibration sensor pixel image.

A method for assigning element addresses in an automated data storage library includes determining if a data storage device, such as a tape cartridge, belongs to a particular host's cartridge assignment policy. If so, the data storage device is issued a virtual import/export element address taken from a set of non-common virtual import/export element addresses, if available. If no non-common address is available, then a common virtual import/export element address is assigned to the data storage device. If no addresses, either common or non-common, are available, then the data storage device is queued until an address becomes available.

Method of assigning virtual import/export element addresses

A system, apparatus, and method are disclosed for conducting an inventory of a data storage library. The invention includes providing a plurality of data storage slots for storing data storage cartridges, providing an accessor having a plurality of detectors mounted thereon, and concurrently detecting cartridge information with the plurality of detectors for a corresponding plurality of data storage slots. The detectors may include any combination of detectors, including but not limited to, bar code scanners, radio frequency readers, cartridge presence sensors, or cameras. In certain embodiments, the invention also includes associating the cartridge information with the corresponding data storage slot and storing the information on a data bearing medium.
