PURPOSE:To minimize the degeneration of a processing by storing AND of the constant mask pattern and a factor which is processible even after the restoration of a service processor and communicating it again to the service processor when the restoration of the service processor is informed. CONSTITUTION:A data transmission control part 4 monitors the result after data transmission, detects the abnormality and the time-out state of the transmission from an adapter 5, detects the abnormality of a service processor 8, and notifies a processing request control part 2 of them. The processing request control part 2, when it is notified of the failure of transmission, takes the AND of the mask pattern preliminarily prepared in a storage part 3 and a SVP0 processing request table. It also fixes the result onto the storage part 3 in a table with the same size as the SVP0 processing request table or a SVP1 processing request table. In such a case, '0' refers to the factor to be rejected due to the failure of transmission; while '1' refers to the factor to be stored up to the restoration of the service processor 8. |
