Si necesitamos averiguar información detallada sobre los discos locales del servidor o volúmenes/LUNs servidas desde cabinas de almacenamiento, como por ejemplo el Disk ID o UUID, podemos utilizar la herramienta de línea de comandos diskpart.exe.
Lo primer es acceder al cmd y ejecutar diskpart.exe, entraremos en la shell de la herramienta:
C:\>diskpart.exe Microsoft DiskPart version 6.1.7601 Copyright (C) 1999-2008 Microsoft Corporation. On computer: ... DISKPART>
Con el carácter «?» vemos la ayuda y los comandos disponibles:

Para ver la información detallada de cada disco, primero lo seleccionamos (podemos ver el número de disco en la herramienta gráfica de administración de discos de Windows):
DISKPART> select disk 1 Disk 1 is now the selected disk.
Si ejecutamos «detail disk» veremos al detalle la información disco/LUN:
