Storage system and storage system construction control method

摘要

In the present invention, memory resources are effectively utilized by virtualizing external memory resources as internal memory resources, and erroneous operations that destroy the cooperative relationship of these memory resource and the like are prevented in advance. An external storage 2 is connected to a main storage 1, and real volumes 2A1 and 2A2 are respectively mapped into virtual volumes 1B1 and 1B2 (S1). The control server 3 respectively acquires construction information 1D and 2D for the respective storages 1 and 2, and stores and controls this construction information in a storage part 3D (S2). When the user inputs operation contents 4A from a control terminal 4 (S3), the control server 3 judges whether or not the operation contents 4A have an effect on the cooperation between the storages 1 and 2 on the basis of the operation contents 4A and the information in the storage part 3D (S4), and performs only operations that do not have an effect (S5).
