An input/output request control system in a multi-processor system includes a plurality of information processing modules (PM). The system comprises a plurality of input/output adapters (ADP) commonly used by each of said information processing modules and a plurality of input/output devices (DVC) divided into groups, each group controlled by one of two input/output adapters. An input/output request maintaining table (LDVC) manages input/output requests from respective information processing modules for each of the input/output devices controlled by said information processing modules by using a queue. Input/output requests from respective information processing modules are processed based on the state of the input/output request maintaining table and the input/output devices.
