Claim:
A storage device, which receives demands for writing and reading data from host devices to control writing and reading data from logical volumes in said storage device, comprising: a storage media configured to provide said logical volumes, a service processor configured to set configuration information of the storage device, and connected to a terminal device, wherein said terminal device receives a command group described on a script sheet, checks a validity of said command group, if said command group is valid, encrypts said command group, and sends said command group and said encrypted command group to said service processor, wherein said service processor receives said command group and said encrypted command group from said terminal device, decrypts said encrypted command group, compares said received command group with said decrypted command group, and determines approval or denial of execution of said command group based on results of the comparison prior to execution of the command group received from the terminal device wherein said command group is related to the configuration information of the storage device; and wherein said storage device maintains, with a history management module, information about command groups for which execution is denied.
