ABSTRACT:
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 storages comprises a plurality of computers that refer to the disk storages. Each of the computers includes a counting module for counting a frequency of accesses to each of the disk storages, 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, 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.
