Abstract
When a redundancy failures occurs in sequentiality-guaranteed data transfer, data transfer in a short period of time is resumed such that wherein when a factor by which the second storage device stops processing of the storage system is multiple failures of the two or more redundant control devices during a process of developing data to a storage medium in the second storage device, a session managing unit sets inconsistency as the copy session state, and a buffer managing unit sets the buffer data lost state, and when a data transfer process is resumed between the first storage device and the second storage device, the session managing unit sets consistency as the copy session state when the buffer data lost state is set by the buffer managing unit.
