Storage system management method, storage system, switch, and storage medium having a program

摘要

A storage system includes storage devices having connection ports and logical device groups connected to each connection port, and a switch having a plurality of switch ports to which the storage devices can be connected via their connection ports and, when a data frame is input to one of the switch ports, being capable of outputting that data frame from either one of the switch ports connected to one of the connection ports to which that data frame is to be sent according to a destination specified in that data frame. The switch stores a table that defines a correspondence between the destination and the connection port. In rearranging data stored in one logical device group to another logical device group, a management server connected to the switch sends an update request to the switch and makes it update the correspondence in the table.
