Hi,

Generally, we may use PowerShell to get the disk information as it does most, if not all, of the WMI work for you.

Below is the article about use Powershell command and WMI command to get disk information, please check if they can help:

if the disk is added as Physical disk, we can get this info using Msvm_ResourceAllocationSettingData --> ConsumerVisibility. This would be set to 2.

But if the disk is added using iscsi initiator, how can we get the disk information. Will check on links, i will update here.

In the example shown in the web links, we need to pass the serverName. Here we are looking for a VM name to be passed. How can we pass the VMname in the commands to Get-WmiObject

C:\> Get-WmiObject -Class Win32_LogicalDisk -computerName Vm2016
Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
At line:1 char:1

Get-WmiObject -Class Win32_LogicalDisk -ComputerName Vm2016

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

CategoryInfo : InvalidOperation: (:) [Get-WmiObject], COMException

FullyQualifiedErrorId : GetWMICOMException,Microsoft.PowerShell.Commands.GetWmiObjectCommand
