Abstract: The present invention unitarily manages the configuration change of a storage system so as to know the latest configuration, and evaluates the reliability in advance when the configuration is changed so that the generation of a failure is suppressed. When the host 1 is connected to the switch 2, the attribute information of HBA 1A and the attribute information of the switch 2 are stored in the connection information storage unit 2C by FDMI (Fabric Device Management Interface) (S1, S2). Each attribute information is associated with each other and is managed as combination information. The storage device 3 acquires the combination information from the switch 2 (S3, S4), and requests the management device 4 to judge the reliability of this combination (S5). The management device 4 judges the combination of the HBA and the switch (S6), and notifies this judgment result to the storage device 3 (S7).

Abstract: A method of accessing a multifile storage medium and a library system. The library system includes recording/reproducing apparatuses for performing a recording/reproducing operation on the multifile storage medium, a plurality of recording/reproduction control units for controlling transaction of information with a host, a plurality of buffers provided between the recording/reproduction control units and the recording/reproducing apparatuses, a library control unit for controlling the whole library system, a directory for recording correspondence between the individual multifile recording media and a plurality of files stored therein, a shelf for housing the multifile storage media and handling devices. The plural buffers can be accessed independently of one another. Plural files are transferred between the buffers and the storage medium on a file-by-file basis. The access requests to the files are disposed of within the buffer.
