Abstract

Dans des conditions de fonctionnement normales, dans un système de processeur double actif en ligne de secours hors ligne, seul le processeur actif en ligne peut avoir accès à la structure de bus du système. Le processeur de secours hors ligne est déconnecté des bus du système. L'invention révèle une technique grace à laquelle un processeur de secours hors ligne peut avoir accès à des fins de diagnostic aux périphériques du sytème via la structure de bus. Le processeur de secours peut alors exécuter un essai de diagnostic afin de déterminer son aptitude à communiquer avec les unités péripheriques du système.
