Method, apparatus, and program for determining correct cartridge orientation in an automated tape library

摘要

An automated media library gathers information about each readable cartridge label using a camera. From the label information, the orientation of the cartridge may be determined. For each cartridge with an unreadable label or no label, the media library attempts a get/put operation. If the get/put operation fails, the cartridge is marked as incorrectly oriented. Alternatively, the tape library may attempt a get/put operation on all removable media cartridges. A similar process is performed when a cartridge access port is closed and the cartridge access port is marked inaccessible to the host when an incorrectly oriented cartridge is detected.
