Introducción
Oracle Sun Cluster es el software que gestiona la alta disponibilidad entre dos servidores Solaris. Oracle Sun Cluster gestiona recursos garantizando su disponibilidad moviendo dichos recursos de un servidor a otro en caso de problemas.
Versión
La versión de Sun Cluster está ligada a la versión de Solaris. Cuando se hace un update es necesario realizarlo a la vez. Se actualiza la versión de Solaris y la versión de Sun Cluster en la misma operación.
Para ver la versión de Sun Cluster ejecutamos los siguientes comandos:
phys-schost# clnode show-rev
4.0
phys-schost#% clnode show-rev -v

Con el siguiente comando podemos comprobar el estado de todos los recursos del cluster comprobando cada recurso en qué nodo está.
El comando indica el estado de los nodos, la red de interconexión, el quorum, los grupos de recursos, los recursos, los discos y el estado del zone cluster.
