Ejemplo: duplicar el sistema de archivos raíz
El ejemplo siguiente muestra la creación de una duplicación d0 en el nodo phys-schost-1 que consiste en una subduplicación d10 en la partición c0t0d0s0 y una subduplicación d20 en la partición c2t2d0s0. El dispositivo c2t2d0 es un disco multisistema, de manera que se habilita la propiedad localonly.
