ProcedureRéinitialisation d'un nœud du cluster

Si vous avez l'intention d'arrêter ou de réinitialiser d'autres nœuds actifs du cluster, attendez que le nœud en cours de réinitialisation ait au moins atteint l'invite de connexion. Sinon, le nœud ne pourra pas reprendre les services des autres nœuds du cluster que vous arrêtez ou redémarrez.

Étapes

  1. SPARC : si votre cluster exploite Oracle Parallel Server ou Oracle Real Application Clusters, fermez toutes les instances de la base de données.

    Reportez-vous à la documentation d'Oracle Parallel Server ou Oracle Real Application Clusters pour connaître les procédures d'arrêt.

  2. Devenez superutilisateur sur le nœud de cluster à arrêter.

  3. Arrêtez le nœud à l'aide des commandes scswitch et shutdown.

    Entrez ces commandes sur nœud à arrêter. L'option -i 6 associée à la commande shutdown réinitialise le nœud préalablement arrêté. 


    # scswitch -S -h node
# shutdown -g0 -y -i6
    Remarque –

    les nœuds de cluster doivent avoir une connexion fonctionnelle avec l'interconnexion du cluster pour en devenir membres.

  4. Assurez-vous que le nœud est correctement initialisé et qu'il est en ligne. 


    # scstat -n
Exemple 3–11 SPARC : Réinitilisation d'un nœud de cluster

L'exemple suivant reproduit l'affichage de la console lors de la réinitialisation du nœud phys-schost-1. Les messages relatifs à ce nœud, tels que les notifications d'arrêt et de démarrage, apparaissent sur les consoles des autres nœuds du cluster. 


# scswitch -S -h phys-schost-1
# shutdown -g0 -y -i6
