Abstract:
A communication control method between an initiator and a target, wherein the initiator has a storage area comprisingthe initiator issuing a predetermined command including an identifier to the target and holding the command; and the target reading out or writing data from or to the storage area of the initiator in response to the command from the initiator, and issuing a completion message to the initiator, wherein the initiator re-issuably holds the issued command until the initiator receives the completion message indicating completion of processing corresponding to the command from the target, and wherein when a connection between the initiator and target is temporarily disconnected and is connected again, the target compares the identifier of the command issued by the initiator with a held identifier, and the target makes a read or write from a held offset of the storage area when the two identifiers match, and issues a process completion message corresponding to the command to the initiator without making a read or write to the storage area of the initiator when the two identifiers do not match.
