powercli | get host uuid truncated

[vinny95]

Hi all,

I am trying to get host uuid through vCenter / Powercli.

When I check directly on my host, I get its UUID :

[root@esxi-01:~] esxcli system uuid get

58817e8c-xxxx-xxxx-xxxx-xxxxxxxxx6d6

But when I check with Powercli on a vCenter 6.0 u2, I got the following :

PowerCLI C:\> (Get-VMHost esxi-01 | Get-View).hardware.systeminfo.uuid

00000000-0000-0000-0000-xxxxxxxxx6d6

There is only the last part of the UUID that is correct (btw I need the first part of the UUID to get installation date of the esxi).

I checked 6.0 u2 esxi & 5.5 u2/u3 : same truncated UUID.

Do you have any idea why the vCenter/powercli is not getting the right/full uuid ?

thanks,

vinny

Those are UUID for two different things, one is for the HW BIOS, the other is the ESXi system UUID.

Get-VMHost | Select Name,

    @{N='HW BIOS Uuid';E={$_.Extensiondata.Hardware.SystemInfo.Uuid}},

    @{N='ESXi System UUid';E={(Get-Esxcli -VMHost $_).system.uuid.get()}}

Update: Alan did a nice post on the different UUIDs. See A Quick Reference of vSphere IDs
