Answer 1

Hi,

The Mount-VHD cmdlet is part of the Hyper-V module. Please check the module versions on your servers using Get-Command Mount-VHD and see if they are the same.

Or you can use Set-CimInstance to set the drive letter. For more details please refer to this link

The sample.

Create file:

C:\Scripts\Mount_VHDX_Drives.ps1

File body:

$VolumesVHDX = Mount-VHD -Path "C:\Disk.vhdx" -PassThru | Get-Disk | Get-Partition | Get-Volume | Select-Object DriveLetter
Set-Partition -DriveLetter $VolumesVHDX.DriveLetter -NewDriveLetter R -Confirm:$false -ErrorAction SilentlyContinue

Run this file with powershell.exe

Command > PowerShell.exe

Arguments > "C:\Mount_VHDX_Drives.ps1"
