If you are like me and you run a large Hyper-V machine with several arrays attached to it I'm sure at some point you've asked or been asked to find out, what virtual machines are on a particular array and what resources they are using. The Hyper-V UI doesn't help which means the PowerShell cmdlet is the answer. However, even using that it isn't straight forward requiring you to push through a command like 

Get-VM | Get-VMHardDiskDrive | where {$_.Path -Like "D:\Virtuals\*"} 

VMName   ControllerType ControllerNumber ControllerLocation DiskNumber Path                      
------   -------------- ---------------- ------------------ ---------- ----                      
ASERVER1       IDE            0                0                             D:\Virtuals\SERVER1.vhdx         
EMAIL1     IDE            1                1                             D:\Virtuals\EMAIL1.vhdx      
XSERVER1     IDE            0                0                             D:\Virtuals\XSERVER1.vhdx   

to get that information. Unfortunately that output just isn't particularly useful as it doens't show enough useful information, I want to know CPU, Memory etc.

So I've written a function that fixes my problem.

 Function Get-VMInLocation { 
 Quickly get a list of all VMs in a given location. 

 Quickly get a list of all VMs in a given location. Output is the same as Get-VM.
 Get-VMInLocation E:
 Get-VMInLocation C:\myvms
 Get-VMInLocation \hyperv\


    $VMArray = @()
    if((Test-Path $path -ErrorAction Stop) -eq $true)
            Get-VM | Get-VMHardDiskDrive | where {$_.Path -Like "$path*"} | Select-Object VMName,path | ForEach-Object {

                $VMObject = New-Object System.Object
                $VMName = $_.VMName
                $VMPath = $_.Path
                $VMObject | Add-Member -Type NoteProperty -Name Name -Value "$VMName"
                $VMObject | Add-Member -Type NoteProperty -Name drive -Value "$VMPath"

                $VMArray += $VMObject
