ADMINISTRACIÓN DE GRUPOS DE RECURSOS
· Crear un grupo de recursos con failover # clresourcegroup create <group>
· Crear un grupo de recursos escalable # clresourcegroup create -S <group>
· Establecer online todos los grupos de recursos # clresourcegroup online +
· Suprimir un grupo de recursos # clresourcegroup delete <group>
· Suprimir un grupo de recursos y todos sus recursos # clresourcegroup delete -F <group>
· Conmutar el nodo principal actual de un grupo de recursos # clresourcegroup switch -n <nodename> <group>
· Cambiar el estado de un grupo de recursos UNMANAGED # clresourcegroup unmanage <group>
· Suspender la recuperación automática de un grupo de recursos # clresourcegroup suspend <group>
· Reanudar la recuperación automática de un grupo de recursos # clresourcegroup resume <group>
· Cambiar una propiedad de un grupo de recursos # clresourcegroup set -p Failback=true + name=value
· Agregar un nodo a un grupo de recursos # clresourcegroup add-node -n <nodename> <group>
· Quitar un nodo de un grupo de recursos # clresourcegroup remove-node -n <nodename> <group>

ADMINISTRACIÓN DE RECURSOS
· Crear un recurso logical hostname # clreslogicalhostname create -g <group> <lh-resource>
· Crear un recurso de haredaddress # clressharedaddress create -g <group> <sa-resource>
· Crear un recurso # clresource create -g group -t <type> <resource>
· Quitar un recurso # clresource delete <resource>
· Deshabilitar un recurso # clresource disable <resource>
· Cambiar una propiedad de recurso de un solo valor # clresource set -t type -p name=value +
· Crear un recurso de HAStorage Plus # clresource create -t HAStoragePlus -g group \ -p FileSystemMountPoints=mount-point-list \ -p Affinityon=true rs-hasp
· Borrar el indicador de error STOP_FAILED de un recurso # clresource clear -f STOP_FAILED <resource>
Diferentes opciones:
create ->Creates the resources that are specified as operands to the command.
delete ->Deletes the resources that are specified as operands to the command.
disable ->Disables resources.
enable ->Enables resources.
export ->Exports the cluster resource configuration.
list ->Displays a list of cluster resources.
list-props ->Displays a list of resource properties.
monitor ->Turns on monitoring for resources.
reset ->Clears error flags that are associated with cluster resources.
set ->Sets resource properties.
show ->Displays resource configuration.
status ->Displays resource status.
unmonitor ->Turns off resource monitoring.

TAREAS DE ADMINISTRACIÓN Y SUPERVISIÓN
- Agregar un nodo a un clúster. Desde el nodo con acceso que se va a agregar: # clnode add -c clustername -n <nodename> -e endpoint1, endpoint2 \ -e endpoint3, endpoint4
- Quitar un nodo del clúster. Desde el nodo con acceso y que no se encuentra en el clúste: # clnode remov
- Conmutar todos los grupos de recursos y dispositivos fuera de un nodo # clnode evacuate <nodename>
- Mostrar el estado de todos los componentes del clúster # cluster status
- Mostrar la configuración del clúster completa # cluster show
- Mostrar la información de versión de Sun Cluster # clnode show-rev -v
CIERRE Y ARRANQUE DE UN CLÚSTER
- Apagar todo el clúster. Desde un nodo # cluster shutdown
- Apagar un solo nodo # clnode evacuate # shutdown
