Abstract:
1. A control method of a data storage system in which multiple external storage systems that store information are connected to a first network and each of said multiple external storage systems is arranged separately, comprising: generating an interrupt by an external storage system to a management server; issuing an exclusive control command by said management server to said external storage system, wherein said exclusive control command temporarily limits access to said external storage system such that said management server is the only control server that enables configuration setting of the data storage system; receiving by said management server, configuration information from said external storage system in response to said command; and storing in a database at said management server said configuration information that said management server received, wherein said management server acquires configuration information of said external storage systems in point of time series and stores said configuration information in the database managed by said management server using said exclusive control command, and wherein a time series acquisition is made with a simultaneous and periodic inquiry into multiple external storage systems as moments.
