Abstract
PURPOSE: To simplify switching with making the best use of the existent processing system by indexing the input/output device management table and setting address information corresponding to an auxiliary input/output device when fault has occurred in a current input/output device.
CONSTITUTION: Correspondingly to each file stored in input/output devices 4 and 5, file control table 11 stores required file control information and device control table 10 stores device control information to have access to devices 4 and 5. Then, address information corresponding to input/output devices are classified for the current input/output device and the auxiliary input/output device and stored in input/output device management table 12 beforehand, and table 12 is indexed to set address information corresponding to the auxiliary input/output device when fault has occurred in the current input/output device. As a result, the switching can be simplified with making the best use of the existent processing system
