Thin Provisioned Disks

[ae_jenkins]

So, I'm pretty good with PowerCLI, but really bad with API calls . . . here goes my question.

The "get-harddisk" cmdlet in v4 of course has the "StorageFormat" property, identifying if the HD is thin or thick. Is there a way (API or otherwise) to pull in both the "defined" vHD size and the actual vHD size? For example, if I give a VM a 40 GB vHD, this is the "defined" size. If I only put 1 GB of data on the vHD, the "actual" size would be roughly 1 GB. I'm looking for that difference (39 GB).

Any ideas? I'm looking at you LucD

Thanks

Alan

Try something like this, it's not to most elegant solution I admit.

$vmName = <vm-name>

$vm = Get-VM $vmName | Get-View
$vm.Config.Hardware.Device | where {$_.DeviceInfo.Label -like "Hard disk *"} | %{
	$hd = $_
	$hdKey = $hd.Key
	$vm.LayoutEx.Disk | where {$_.Key -eq $hdKey} | %{
		$files = $_.Chain | %{$_.FileKey} | %{$_}
	}
	$allocated = 0
	$vm.LayoutEx.File | where {$files -contains $_.Key} | %{
		$allocated += $_.Size
	}
	Write-Host $hd.DeviceInfo.Label $hd.CapacityInKB ($allocated/1KB)
}

The sizes are displayed in KB.

Fyi, I expanded on the script below in yadr – A vdisk reporter.

Hi LucD

Wow - thanks so much for all this information - I have been pulled away from this task temporarily, but with all the work you put into this I'm sure it's either totally correct or will send me in the right direction. Points to you sir.
