Abstract

PURPOSE: To avoid the unnecessary power consumption by cutting off the power supply of the input/output control device in case the recovery cannot be secured for the control device even though the retrial is carried out in several times through the control device.
CONSTITUTION: When the fault is detected in input/output control device 1, command retrial request signal 3 is transmitted to input/output processor 2. And with detection of signal 3 at processor 2, the command retrial is carried out. In this case, if device 1 cannot be recovered even with performance of the retrial in several times at processor 2, the power supply is cut off fro device 1. Thus, the unnecessary power consumption can be avoided for the device.
