Abstract

PURPOSE:To operate CPU effectively, by allowing a controller to report a command retrial status to a channel after CPU has once issued to the controller. CONSTITUTION:Once CPU2 issues a command to a controller 3A, writing of the same data, that is, copying on plural external storage devices DASD 7A-7C can be executed between a channel 5 and the controller 3A independent of CPU2, thus permitting CPU2 to be made unnecessary to issue a command each time the same data are written on DASD 7A-7C, and CPU2 to be effectively operated.
