ABSTRACT:
This invention provides a computer system capable of achieving frequent accesses to the same logical volume by a plurality of computers by using iSCSI. The computer system includes first computers not supporting iSCSI and second computers supporting iSCSI. A load distribution control part determines a requested computer to be requested about a command processing and requests the command processing. The requested computer requests an IO control part about an access to a logical volume in a shared disk. When the requested computer does not support iSCSI, the IO control part selects a substitute computer. The substitute computer mounts the logical volume on behalf of the requested computer to provide the mounted logical volume to the requested computer through NFS.
