Online VHDX Resize with SCVMM 2012 R2

Yesterday I discussed how to expand the size of a virtual hard disk on a running virtual machine.  You can also do this with System Center Virtual Machine Manager 2012 R2.  To do this you need to:

1. Open Properties on the virtual machine in question
2. Go to Hardware Configuration
3. Locate the disk you want to resize
4. Select Expand virtual hard disk (GB): and enter the new size that you want
5. Click OK

You can also use SCVMM PowerShell to do the same thing:

Get-SCVirtualMachine "Windows Server - Resize" | Get-SCVirtualDiskDrive | ?{$_.VirtualHardDisk -like "Windows Server - Resize_disk_1"} | Expand-SCVirtualDiskDrive -VirtualHardDiskSizeGB 140

Note, just like I discussed yesterday:

• You can only do this for .VHDX files attached to SCSI controllers
• After doing this you will need to login to the guest operating system and do something to take advantage of the new space

Cheers,
Ben
