Liste des codes de la méthode xfnts_start

Le gestionnaire RGM exécute la méthode Start sur un noeud de cluster lorsque le groupe de ressources qui contient la ressource du service de données est mis en ligne sur ce noeud ou lorsque la ressource est activée. La méthode dedémarrage_xfnts active le démon xfs sur ce noeud.
