Retrieving LUN Serial Numbers with Windows PowerShell

Updated — March 12, 2016

I have been asked this question more than I have fingers and toes so I figured I would do a quick post providing the Windows PowerShell that will retrieve the Serial Number for any LUN connected to a Windows Server.

$AllDevices = gwmi -Class Win32_DiskDrive -Namespace 'root\CIMV2'
ForEach ($Device in $AllDevices) {
 if($Device.Model -like 'PURE FlashArray*') {
   @{
    Name=$Device.Name;
    Caption=$Device.Caption;
    Index=$Device.Index;
    SerialNo=$Device.SerialNumber;
   } | Format-Table -AutoSize
  }
}

The Index corresponds to what the Windows Disk Management displays. Now there is a 1:1 mapping of Device Index and Serial Number that can be used for automation tasks.
