Para realizarlo, voy a agregar al DiskGRoup ya existente, de nombre BGT, 4 discos de igual capacidad.
Primero los voy a labelear con el Format, luego un vxdctl enable para que los vea Veritas.
Luego con el vxdiskadm voy a agregar esos discos al DG existente BGT.
Despues Mirroreo los volumenes con el vxassist, chequeo el status con vxtask list.
Cuando finalize, corto el mirror y saco las referencias a los discos viejos dentro del veritas.
Toda la tarea me Llevo 40 minutos aproximadamente, eltotal ocupado de los vol/fs era de 120 gb.
