Abstract: In a method for processing a server message block (SMB) service fault, a first storage device generates a file handle according to a first file open instruction from a host, and sends the file handle to a second storage device. The second storage device stores the file handle as a backup handle. The second storage device activates an Internet Protocol (IP) address of the first storage device according to fault information from the first storage device, and establishes a communication connection to the host. After the second storage device determines a file handle matches the handle identifier, the second storage device opens a file. Hence, when a storage device that processes an SMB service is faulty, the SMB service may be taken over by a secondary storage device such that the SMB service is executed without interruption.
