Script to relate Hyper-V VHDs on Cluster Volumes to their respective LUNs

ginolard2010 — Thu, 05 Jun 2025 06:48:46 GMT

I was asked to produce a report that showed what VHDs were in use, what Cluster Volume they are on and, subsequently, what LUN it is. Thanks to Get-NaHyperV that was preposterously easy. I thought others might benefit from this script so here it is.

You'll need to change the values of $adminID and $pass for your filers

File is also attached.

$VMs=get-nahyperv |select name,storage

$adminID = "CHANGE_ME"

$pass = ConvertTo-SecureString "CHANGE_ME" -AsPlainText -Force

$cred = New-Object -TypeName System.Management.Automation.PSCredential -ArgumentList $adminID,$pass

$objstorageinfo =@()

foreach ($VM in $VMs){

$storageinfo=$VM.storage|Select *

foreach ($storageprop in $storageinfo){

If (Test-Path $storageprop.VmDiskResourceName){

$VHDSize = gi $storageprop.VmDiskResourceName |select @{Name="SizeInGB";Expression={[Math]::Round($_.Length/1GB)}}

$conn=Connect-naController $storageprop.ControllerName -credential $cred

$csv = Get-ClusterSharedVolume $storageprop.ClusterResource

$objcsvSizeInfo =$csv | select -Expand SharedVolumeInfo|select -expand partition

$LUN=Get-NalUN $storageprop.ControllerLunPath|select @{Name="SizeInGB";Expression={[Math]::Round($_.Size/1GB)}},@{Name="UsedSizeInGB";Expression={[Math]::Round($_.SizeUsed/1GB)}}

$lunID = (get-nalunmap $storageprop.ControllerLunPath).lunid

$Vol=Get-NalUN $storageprop.ControllerLunPath|Get-Navol |select name,ContainingAggregate,@{Name="SizeInGB";Expression={[Math]::Round($_.SizeTotal/1GB)}},`

@{Name="UsedSizeInGB";Expression={[Math]::Round($_.SizeUsed/1GB)}},`

@{Name="FreeSizeInGB";Expression={[Math]::Round($_.SizeAvailable/1GB)}}

$Aggr = Get-NaAGGr $VOL.ContainingAggregate|select name,@{Name="SizeInGB";Expression={[Math]::Round($_.SizeTotal/1GB)}},`

@{Name="UsedSizeInGB";Expression={[Math]::Round($_.SizeUsed/1GB)}},`

@{Name="FreeSizeInGB";Expression={[Math]::Round($_.SizeAvailable/1GB)}}

$myobj = New-Object PSObject -Property @{

VMName = $VM.Name

VHDPath = $storageprop.VmDiskResourceName

VHDSize = $VHDSize.SizeInGB

CSVName = $storageprop.ClusterResource

CSVPath = $storageprop.HostDrivePath

CSVSize = [Math]::Round($storageprop.size/1GB)

CSVFreeSize = [Math]::Round($objcsvSizeInfo.Freespace/1GB)

HostDisk = $storageprop.HostDiskName

LUNPath = $storageprop.ControllerLunPath

LUNID = $lunID

LUNSize = $LUN.SizeInGB

LUNSizeUsed = $LUN.UsedSizeInGB

VolName = $Vol.Name

VolSize = $Vol.SizeInGB

VolUsedSize = $Vol.UsedSizeInGB

VolFreeSize = $Vol.FreeSizeInGB

AggrName = $Aggr.Name

AggrSize = $Aggr.SizeInGB

AggrUsedSize = $Aggr.UsedSizeInGB

AggrFreeSize = $Aggr.FreeSizeInGB

SANName = $storageprop.ControllerName

}|select VMName,VHDPath,CSVName,CSVPath,CSVSize,CSVFreeSize,@{Label="CSVUsedSize";Expression = {$_.CSVSize-$_.CSVFreeSize}},HostDisk,`

LUNPath,LUNID,LUNSize,LUNSizeUsed,@{Label="LUNSizeFree";Expression = {$_.LunSize-$_.LunSizeUsed}},`

VolName,VolSize,VolUsedSize,VolFreeSize,`

AggrName,AggrSize,AggrUsedSize,AggrFreeSize,SANName

$objstorageinfo += $myobj

}

$objstorageinfo|export-csv .\NetAPP-VHD.csv -notypeinformation

Script to relate Hyper-V VHDs on Cluster Volumes to their respective LUNs

That's a great use of the Cmdlets! It's cool to see all of the host side info & filer info joined together in one view from the VHD up to the aggregate.

Thanks for posting! "preposterously easy" is the goal.
