5.11. Répertorier les services cluster disponibles
vous pouvez utiliser la commande
ccs pour imprimer une liste des services disponibles à un cluster. Vous pouvez aussi utiliser la commande ccs pour imprimer une liste des options pouvant être spécifiées pour un type de service particulier.
Pour imprimer une liste des services cluster actuellement disponibles pour votre cluster, exécutez la commande suivante :
ccs -h host --lsserviceopts
Par exemple, la commande suivante répertorie les services cluster disponibles sur le nœud
node1 du cluster, affichant un exemple de sortie.
[root@ask-03 ~]# ccs -h node1 --lsserviceopts

Pour imprimer une liste des options que vous pouvez spécifier pour un type de service particulier, exécutez la commande suivante :
