Cómo ver información de las LUNs de la SAN

Introducción
Si queremos obtener información de las LUNs que vemos a través de nuestras HBA, utilizaremos el comando luxadm con la opción probe, y para obtener un detalle la opción display {raw_device}, por ejemplo,
# luxadm probe
No Network Array enclosures found in /dev/es

Found Fibre Channel device(s):
