Getting Hardware UUID

134.35.175.52: /* VMWare ESXi */

Every system has a universally unique identifier (UUID) value set onto the system. The UUID is a 128-bit value typically displayed in lowercase hexadecimal digits in 5 groups separated by dashes. An example UUID would look like {{code|5178962d-2fcf-df50-536d-000423d9985a}}.

While software packages may make use of pseudo random UUIDs, this article will cover only system hardware UUIDs.

==Windows==
You may get the UUID value from PowerShell.
{{highlight|lang=terminal|code=
> get-wmiobject Win32_ComputerSystemProduct {{!}} Select-Object -ExpandProperty UUID
}}

==Linux / FreeBSD==
Use the {{code|dmidecode}} utility to get the UUID
{{highlight|lang=terminal|code=
# dmidecode -s system-uuid
}}

You may need to install {{code|dmidecode}} since it usually isn't bundled with the base OS. On FreeBSD, it's available in ports at {{code|/usr/ports/sysutils/dmidecode}}.

==VMWare ESXi==
To get the UUID of the physical machine that your ESXi server is running on, login via SSH and run:

{{highlight|lang=terminal|code=
<nowiki>
# esxcfg-info | grep -i uuid
</nowiki>
}}

You will see a bunch of UUIDs, most of which pertain to disks/volumes. What you are looking for is:

{{highlight|lang=text|code=
<nowiki>
|----System UUID..............................................5178962d-2fcf-df50-536d-000423d9985a
</nowiki>
}}
