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 host1is connected to the switch2, the attribute information of HBA1A and the attribute information of the switch2are stored in the connection information storage unit2C by FDMI (Fabric Device Management Interface) (S1, S2). Each attribute information is associated with each other and is managed as combination information. The storage device3acquires the combination information from the switch2(S3, S4), and requests the management device4to judge the reliability of this combination (S5). The management device4judges the combination of the HBA and the switch (S6), and notifies this judgment result to the storage device3(S7). When the configuration of the storage system is changed, the reliability of the configuration can be confirmed before starting operation with the configuration after change, and therefore the generation of a failure can be decreased.
