Data storage system and control method thereof
First Claim
1. A control method of a data storage system in which multiple external storage systems those store information are connected to a first network and each of them 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;
receiving by said management server, configuration information with which said external storage systems respond; and
storing in a database said configuration information that said management server received.

Abstract
In the configuration of multiple (M units of) disk subsystems shared from multiple (N units of) hosts, having
an exclusive control command that limits access to all disk subsystems temporarily is provided,
using this exclusive control command, configuration information of all multiple disk subsystems, for example, performance and a setting change, are acquired in point of time series and stored in a management server database (“configuration information database”), then managed in a centralized manner,
a function that associates the file that the application uses with the “configuration information database” is provided using a function that detects the position on the logical unit, and
a means that can retrieve the modified contents of the system configuration and time as keys is provided in the “configuration information database”.

15. A control method of a data storage system in which multiple computers those use information and multiple external storage systems those store information are connected to a network respectively, each of them is arranged separately, and the data storage system has a management server connected via a first network, comprising:
-
inputting a file type and time those said multiple computers use, to said management server;
retrieving by said management server a configuration information database and displaying a physical storage position of a logical unit that corresponds to said file;
retrieving another logical unit related to said physical storage position and displaying said another logical unit;
retrieving data in which a modification history of said data storage system is accumulated, and displaying modified contents of said data storage system related to said storage position before said time;
retrieving data in which a performance history of a logical unit is accumulated, and displaying a performance of a logical volume after said time; and
displaying or posting said modified contents of said system when the performance of said logical volume is degraded.
