In one embodiment of the invention, a disk storage accessing system for enabling a plurality of computers to share and access a plurality of disk storage comprises a plurality of computers that refer to the disk storage. Each of the computers includes a counting module for counting a frequency of access to each of the disk storage, and a module for receiving an access path change command to change access paths for the computer to access a different disk storage according to the command. The system further comprises an instructing module for collecting and totaling a frequency of accesses to each disk storage, as counted by the counting module of each of the computers, as well as instructing a particular disk storage as a copy source disk storage to copy content in the copy source disk storage into one or more other disk storage as one or more target disk storage when the totaled access frequency is higher than a predetermined value, and for instructing the receiving module of a computer that accesses the copy source disk storage after receiving a report of copy completion, to change access paths so as to access a target disk storage instead of the copy source disk storage.
