Abstract

PURPOSE:To perform tests for machine check processing function without requiring operators by generating an instruction instructing the generation of pseudo machine check from a test program and restarting a processor from a service processor. CONSTITUTION:A processor 1 and a service processor 2 offering the operation and required functions for the maintenance service are provided. When the processor 1 automatically performs a test of the case in check stop with a test program, the test mode is designated with the program instruction, and an instruction indicating the generation of pseudo machine check is generated to a machine check control unit 20 with a test program. When it is detected that a check stop display element 35 turns on, the processor 2 generates an instruction restarting the processor 1.
