Data processing system
First Claim
1. A data processing system, comprising:
- a first storage system;
a second storage system;
a host system for executing data I/O with said first storage system; and
a management unit for controlling said first storage system and said second storage system, said components being communicably connected among one another through a network, wherein said first storage system has first storage devices and a first logical volume which is set in said first storage devices, said first storage system further including a second logical volume, said second storage system has second storage devices and a third logical volume which is set in said second storage devices and mapped in said second logical volume of said first storage system, and said management unit includes;
an information management table which fetches configuration information of said first storage system and configuration information of said second storage system and stores mapping information of said second logical volume of said first storage system and said third logical volume of said second storage system; and
pair creating means for executing the pair creation when performing copy process, in which said first logical volume of said first storage system is set as a primary volume of copy source and said second logical volume of said first storage system mapped from said third logical volume of said second storage system is set as a secondary volume of copy destination by using said information management table.

Abstract
This invention provides a control technique of a data processing system, in which functions of a highly-functional high-performance storage system are achieved in an inexpensive storage system so as to effectively use the existing system and reduce the cost of its entire system. This system has a RAID system, an external subsystem, a management server, a management client and the like. The management server includes an information management table for storing mapping information of the RAID system and the external subsystem. When performing copy process, the pair creation in which a logical volume of the RAID system is set as a primary volume of copy source and a logical volume of a mapping object of the RAID system mapped from the logical volume of the external subsystem is set as a secondary volume of copy destination is executed from the management client by using the information management table.
