Sun Cluster 3.2 (2)

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
