This gives the devicename of each RDM disk for each vm.

$report = @()
$vms = Get-VM | Get-View
foreach($vm in $vms){
  foreach($dev in $vm.Config.Hardware.Device){
    if(($dev.gettype()).Name -eq "VirtualDisk"){
	  if($dev.Backing.CompatibilityMode -eq "physicalMode"){
	    $row = "" | select VMName, HDDeviceName, HDFileName
          $row.VMName = $vm.Name
	    $row.HDDeviceName = $dev.Backing.DeviceName
	    $row.HDFileName = $dev.Backing.FileName
	    $report += $row
	  }
	}
  }
}
$report

Could it be that there are no raw disks ?
Perhaps try without the test for "physicalMode".

$report = @() 
$vms = Get-VM | Get-View 
foreach($vm in $vms) {
			foreach($dev in $vm.Config.Hardware.Device)	{
				if(($dev.gettype()).Name -eq "VirtualDisk")	{ 
#					if($dev.Backing.CompatibilityMode -eq "physicalMode"){ 
						$row = "" | select VMName, HDDeviceName, HDFileName 
						$row.VMName = $vm.Name 
						$row.HDDeviceName = $dev.Backing.DeviceName 
						$row.HDFileName = $dev.Backing.FileName 
							$report += $row 
					} 	
#				} 
			} 
} 
$report

Thanks mate, is working now:

$report = @()

$vms = Get-VM | Get-View

foreach($vm in $vms) {

foreach($dev in $vm.Config.Hardware.Device) {

if(($dev.gettype()).Name -eq "VirtualDisk") {

$row = "" | select VMName, HDDeviceName, HDFileName

$row.VMName = $vm.Name

$row.HDDeviceName = $dev.Backing.DeviceName

$row.HDFileName = $dev.Backing.FileName

$report += $row

}

$report

Just came to realise that RDMs come in 2 flavours, physical and virtual.
Since I only tested for physical and your RDMs are probably in virtual compatibility mode they didn't show.

This script should only show RDMs but for both compatibility modes

$report = @()
$vms = Get-VM | Get-View
foreach($vm in $vms){
  foreach($dev in $vm.Config.Hardware.Device){
    if(($dev.gettype()).Name -eq "VirtualDisk"){
	  if(($dev.Backing.CompatibilityMode -eq "physicalMode") -or 
	     ($dev.Backing.CompatibilityMode -eq "virtualMode")){
	    $row = "" | select VMName, HDDeviceName, HDFileName, HDMode
          $row.VMName = $vm.Name
	    $row.HDDeviceName = $dev.Backing.DeviceName
	    $row.HDFileName = $dev.Backing.FileName
	    $row.HDMode = $dev.Backing.CompatibilityMode
	    $report += $row
	  }
	}
  }
}
$report

This script is great. Just as an FYI, instead of looking for disks that are virtual or physical mode, I looked for disks that were not equal to flat.

Hi,

This script is great is there a way to get it to output what ESX host the VMs are on?? Is there a property for the host within the $vm object??? something like $vm.Host??

Thanks

Emma

Yes, the VirtualMachine object contains, under the Runtime.Host property, a MoRef to the host on which the VM is running or assigned.
The script could then be something like this:

$report = @()
$vms = Get-VM  | Get-View
foreach($vm in $vms){
  foreach($dev in $vm.Config.Hardware.Device){
    if(($dev.gettype()).Name -eq "VirtualDisk"){
	  if(($dev.Backing.CompatibilityMode -eq "physicalMode") -or 
	     ($dev.Backing.CompatibilityMode -eq "virtualMode")){
	    $row = "" | select VMName, VMHost, HDDeviceName, HDFileName, HDMode, HDsize
          $row.VMName = $vm.Name
	    $row.VMHost = (Get-View $vm.Runtime.Host).Name
	    $row.HDDeviceName = $dev.Backing.DeviceName
	    $row.HDFileName = $dev.Backing.FileName
	    $row.HDMode = $dev.Backing.CompatibilityMode
           $row.HDSize = $dev.CapacityInKB
	    $report += $row
	  }
	}
  }
}
$report

Does anyone know how to add the device name to the output? For example, instead of just the vmhba notitation, can you also get something like this:

EMC Fibre Channel Disk (naa.60060480000190100744533031393736)

Thanks!

I suspect you are after the DisplayName as it's called in the SDK Reference.
Try this script, the DisplayName has been added.

$report = @()
$vms = Get-VM | Get-View
foreach($vm in $vms){
	foreach($dev in $vm.Config.Hardware.Device){
		if(($dev.gettype()).Name -eq "VirtualDisk"){
			if(($dev.Backing.CompatibilityMode -eq "physicalMode") -or 
			($dev.Backing.CompatibilityMode -eq "virtualMode")){
				$row = "" | select VMName, VMHost, HDDeviceName, HDFileName, HDMode, HDsize, HDDisplayName
				$row.VMName = $vm.Name
				$esx = Get-View $vm.Runtime.Host
				$row.VMHost = ($esx).Name
				$row.HDDeviceName = $dev.Backing.DeviceName
				$row.HDFileName = $dev.Backing.FileName
				$row.HDMode = $dev.Backing.CompatibilityMode
				$row.HDSize = $dev.CapacityInKB
				$row.HDDisplayName = ($esx.Config.StorageDevice.ScsiLun | where {$_.Uuid -eq $dev.Backing.LunUuid}).DisplayName
				$report += $row
			}
		}
	}
}
$report
