Hierarchical storage system, library apparatus, magazine, and control method of the hierarchical storage system

摘要

A hierarchical storage system has a disc drive, a library apparatus, and a control apparatus. The library apparatus houses a magazine that houses a cartridge. The cartridge has a first tag and stores a storage medium configured to store the data. The magazine has a second tag. The library apparatus acquires through radio communications first information held by the first tag and configured to identify the cartridge and second information held by the second tag and configured to identify the magazine. The library apparatus transmits to the control apparatus the acquired first and second information. The control apparatus memorizes the first and second information, and manages a location of the data based on a data transfer status between the disc drive and the library apparatus and the first information and the second information stored in the first memory.
