Library device and library device control method

A library device control method which is used in a library device comprising:

• at least an ejection slot which is shared by a plurality of external devices;
• a physical library unit which contains a plurality of physical recording media and is divided into a larger number of areas than the number of said ejection slots;
• logical library units each of which contains a plurality of logical recording media and are logically correlated with each of said areas;
• a logical library information storage unit which stores connection information indicating a connection relationship between each of said logical library units and each of said external devices;
• and a control unit which correlates the recording medium with said logical library units when each of said physical recording media are ejected, comprising:
• referring to said logical library information storage unit in response to a reception of an export process command from said external device;
• and
• identifying one of said logical library units which is correlated with a physical recording medium in said physical library unit which has been ordered by said export process command to been ejected from said ejection slot;
• and
• correlating, in the identified logical library unit, said ejection slot to a logical recording medium which is correlated to said physical recording medium which has been ordered to been ejected.

A non-transitory recording computer readable medium for storing a control program, which is used in a library device comprising:

• at least an ejection slot which is shared by a plurality of external devices;
• a physical library unit which contains a plurality of physical recording media and is divided into a larger number of areas than the number of said ejection slots;
• logical library units each of which contains a plurality of logical recording media and are logically correlated with each of said areas;
• a logical library information storage unit which stores connection information indicating a connection relationship between each of said logical library units and each of said external devices;
• and a control unit which correlates the recording medium with said logical library units when each of said physical recording media are ejected, which makes a computer execute:
• a referring processing in which refers to said logical library information storage unit in response to a reception of an export process command from said external device;
• and
• an identifying processing in which identifies one of said logical library units which is correlated with a physical recording medium in said physical library unit which has been ordered by said export process command to been ejected from said ejection slot;
• and
• a correlating processing in which correlates, in the identified logical library unit, said ejection slot to a logical recording medium which is correlated to said physical recording medium which has been ordered to been ejected.
