PROBLEM TO BE SOLVED: To reduce processing time required when a storage control device fails in an active-active storage system.SOLUTION: For each segment group, a normal identifier is associated with a buddy identifier in a mirror LUN management table 40b, and a control module 3 identifier is associated with state information in a module management table 40a. A volume processing unit 47 selects a control module 3 for performing processing of a mirror LUN on the basis of the mirror LUN management table 40b and the module management table 40a, and issues an I/O to a selected control module 3.SELECTED DRAWING: Figure 6 |
