PROBLEM TO BE SOLVED: To provide a computer system to enable more sufficient common use of a storage device even when an operating system to insufficiently support the common use of the storage device is used. SOLUTION: An exclusive access right is acquired by creating a filter driver 51 in the operating system 50, hooking a MOUNT request, executing a MOUNT processing 110 before normal connection is performed and issuing a RESERVE command of SCSI. In addition, the exclusive access right is renounced by providing a dismount helper 41, periodically executing a DISMOUNT processing 210 and issuing a RELEASE command.
