Summary:PROBLEM TO BE SOLVED: To provides a computer system achieving frequent accesses to the same logical volume by a plurality of computers by using iSCSI(Internet SCSI). SOLUTION: The computer system includes first computers 1 not supporting iSCSI and second computers 2 supporting iSCSI. A load distribution control part 4 determines a requested computer to be requested about a command processing and requests the command processing (S1, S2). The requested computer requests an IO control part 5 about an access to a logical volume in a shared disk 7 (S3). When the requested computer does not support iSCSI, the IO control part 5 selects a substitute computer (S4). The substitute computer mounts the logical volume on behalf of the requested computer (S5) to provide the mounted logical volume to the requested computer through NFS (Network File System) (S6).
