Abstract

Where a plurality of channels terminate in a control unit, the control unit is kept available to some of its channel interfaces when a hard error occurs therein. This is achieved by a method of maintaining the maximum number of channel interfaces in a communicating mode and locking the occurrence of any failure, if at least one channel interface fails.
