Correlate Physical Device ID to Volume Device ID

Question

I'm trying to utilize WMI via PowerShell to run through SAN storage on remote servers to grab the Windows disk management volume label.

The only way I've found to do this is to correlate the volume device id (\\?\Volume{34243...} with the physical disk device ID (\\.\PHYSICALDRIVE01).

However, I haven't been able to find out how to link those two fields together. Is this possible with WMI?

For volumes that were assigned a drive letter you can correlate disks and volumes like this:

Get-WmiObject Win32_DiskDrive | ForEach-Object {
  $disk = $_
  $partitions = "ASSOCIATORS OF " +
                "{Win32_DiskDrive.DeviceID='$($disk.DeviceID)'} " +
                "WHERE AssocClass = Win32_DiskDriveToDiskPartition"
  Get-WmiObject -Query $partitions | ForEach-Object {
    $partition = $_
    $drives = "ASSOCIATORS OF " +
              "{Win32_DiskPartition.DeviceID='$($partition.DeviceID)'} " +
              "WHERE AssocClass = Win32_LogicalDiskToPartition"
    Get-WmiObject -Query $drives | ForEach-Object {
      $driveLetter = $_.DeviceID
      $fltr        = "DriveLetter='$driveLetter'"
      New-Object -Type PSCustomObject -Property @{
        Disk        = $disk.DeviceID
        DriveLetter = $driveLetter
        VolumeName  = $_.VolumeName
        VolumeID    = Get-WmiObject -Class Win32_Volume -Filter $fltr |
                      Select-Object -Expand DeviceID
      }
    }
  }
}

Otherwise it doesn't seem possible with WMI.

On Windows 8/Server 2012 or newer you could use the Get-Partition cmdlet, though:

Get-Partition | Select-Object DiskNumber, DriveLetter, @{n='VolumeID';e={
  $_.AccessPaths | Where-Object { $_ -like '\\?\volume*' }
}}
