That helps to see which SCSI controller you are dealing with for the VM. The final SCSI Controller, SCSI Controller 3, is the highest Location, so Location 256. The next is the next highest number, so Location 224. So the lowest Location is the first controller or SCSI Controller 0. The first controller and each consecutive controller are addressed sequentially or at least in all cases I have seen. The Location is the clue here on which controller is which. What though if like the VM configuration I have pictured above, you have multiple SCSI controllers? Below I have opened the properties of the multiple disks to show how you can tell which disks are on which controller, then you can look at the SCSI ID. Multiple hard disks on multiple SCSI controllers Looking at the scsi address for the vmdk hard disk 2. Below, I still have the screenshot for the multiple controllers, but a single controller VM will have the SCSI addresses for multiple disks of: Notice the SCSI identifier below is also a 1. Looking at the target id for the vmware virtual disk scsi disk device propertiesįor the corresponding VMDK, we will look for the disk with the same SCSI identifier. If you have a single SCSI controller, you will look at the disks on the SCSI controller and see which disk has an ID of 1. On the General tab, look at the location. This will bring up the VMware Virtual disk SCSI Disk Device Properties. Right-click the Disk # tile and select properties. You can get to disk management by typing diskmanagement.msc.

How do you determine which VMDK backs which disk?įirst, look at the properties of the Windows Server disk in disk management. For many, they will be using multiple disks connected to a single SCSI controller. This may be the more likely scenario of the two listed. Multiple hard disks on a single SCSI controller Vm configuration showing the scsi controllers and hard disks 1. This makes it difficult to determine simply by looking at the size of the disks to determine which VMDK is backing the Windows Server disk.

Multiple hard disks on multiple SCSI controllersĪs you can see below, the three different disks are the exact same size.

Multiple hard disks on a single SCSI controller.

Let’s take a look at what you need to look at. However, there are a few things we can look at that can help us put “two and two” together to determine which VMDKs are matched to which Windows Server disks. However, when the disk sizes are the exact same in Windows, this is when things get a bit tricky or at least not too obvious.

You can simply look at the Windows disk and the corresponding VMDKs allocated to the VMware VM and match them that way. Finding VMDK to Windows disk matching is easy enough to do when disk sizes are totally different. The way to find which VMDK your Windows Server Disk matches is not strikingly obvious when looking at Windows Server disk statistics and vSphere Client virtual machine properties. Find Which VMDK your Windows Server Disk matches

Let’s take a look at how to find which VMDK your Windows Server Disk matches.

How can you match Windows disk with VMware VMDK to see which drive to extend? Also, what if you have multiple SCSI controllers in play with your VMware vSphere VM? This confuses things even more. Also, as most of you know, you can’t go by the order of the drive lettering and other clues in Windows to effectively find which VMDK is associated with which Windows disk. Have you ever been in the situation of needed to extend a Windows Server hard disk in a VMware vSphere VM and was unsure which disk to extend? This is especially the case if you have multiple disks that are configured as the same size.
