Averiguar detalles como el Disk ID (UUID) de una LUN en Windows

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
