Identify LUN IDs in Windows Server 2012 R2

During a Windows Server 2012 R2 Hyper-V implementation I needed to identify all the iSCSI disks (LUNs) presented by an EMC VNX SAN to the Hyper-v Failover cluster. Each presented iSCSI disk has a unique LUN ID. To View the LUN ID of a disk, you can use the diskpart command. Here are the steps to view the LUN ID of a disk:

  • View the disks

list disk

  • Select a disk

select disk <number>


  • View the LUN ID of the disk

detail disk


I didn’t find a PowerShell command to view the LUN IDs. You can create a PowerShell script that uses Diskpart to view all the disks and the corresponding LUN IDs.
