Réinitialisation d'un cluster
Exécutez la commande scshutdown( 1M) pour arrêter le cluster, puis initialisez le cluster à l'aide de la commande boot( 1M) sur chaque noeud.
-
SPARC : si votre cluster exploite Oracle Parallel Server/Real Application Clusters, fermez toutes les instances de la base de données.
Reportez-vous à la documentation d'Oracle Parallel Server/Real Application Clusters pour connaître les procédures d'arrêt.
-
Devenez superutilisateur sur un noeud du cluster.
-
Arrêtez le cluster.
Sur un noeud du cluster, entrez la commande suivante :
# scshutdown -g0 -y
Chaque noeud est arrêté.
Remarque :les noeuds de cluster doivent avoir une connexion fonctionnelle avec l'interconnexion du cluster pour en devenir membres.
-
Initialisez chaque noeud.
L'ordre d'initialisation des noeuds n'a aucune incidence, sauf si vous modifiez la configuration entre les arrêts. Si vous modifiez la configuration entre les arrêts,dans ce cas initialisez d'abord le noeud dont la configuration est la plus récente.
-
SPARC :
ok boot

-
Vérifiez que les noeuds sont correctement initialisés et qu'ils sont en ligne.
La commande scstat(1M) récapitule le statut des noeuds.
# scstat -n
Remarque :si le système de fichiers /var du noeud d'un cluster est saturé, il est possible que Sun Cluster ne puisse pas redémarrer sur ce noeud. Le cas echéant, reportez-vous à la rubrique Réparation d'un système de fichiers /var saturé.
SPARC: exemple de réinitialisation d'un cluster
L'exemple suivant reproduit l'affichage de la console lors d'un arrêt normal du cluster avec retour de tous les noeuds à l'invite ok, suivi du redémarrage du cluster. L'option -g 0 remet le délai à zéro et -y répond automatiquement oui à la demande de confirmation. Les messages d'arrêt apparaissent également sur les consoles des autres noeuds du cluster.
