ABSTRACT:
A computer and a backup computer exchange periodic report signal transmissions by way of SVP115. When there is no periodic report signal transmission from the main computer, the backup computer makes a main computer status inquiry and if one location is malfunctioning resets the main computer by way of the SVP115 and continues the processing. When permanent damage is present, the SVP115 continually resets the main computer and controls MOS switches of the common disk unit to isolate the SCSI from the main computer and continue the main computer processing.
