Detailed Description

The Convert-SCVirtualDiskDrive cmdlet converts an existing virtual hard disk attached to a virtual disk drive object from dynamic to fixed or from fixed to dynamic, from VHD to VHDX, or converts a pass-through disk attached to a virtual disk drive object to a virtual hard disk.

CONVERTING A VIRTUAL HARD DISK FROM DYNAMIC TO FIXED, OR VICE VERSA

----------------------------------------------------------------

To convert the virtual hard disk from one format to the other, the virtual machine on which the virtual hard disk is configured must be in a stopped state.

You can only convert the disk format of a Windows-based virtual hard disk file (a .vhd file) on a virtual machine deployed on a Hyper-V host.

A VMware-based virtual hard disk file (a .vmdk file) on a virtual machine that is deployed on an ESX host is fixed in format and therefore cannot be converted to a dynamic format.

A Citrix XenServer-based virtual hard disk file (a .vhd file) on a virtual machine that is deployed on a Citrix XenServer host is also fixed in format and therefore cannot be converted to a dynamic format.

CONVERTING A VHD TO VHDX

--------------------------------------------------

To convert a VHD to VHDX, the virtual machine on which the virtual hard disk is configured must be in a stopped state.

You can only convert the disk format of a Windows-based virtual hard disk file from VHD to VHDX on a virtual machine deployed on a Hyper-V host.

CONVERTING A PASS-THROUGH DISK TO A VIRTUAL HARD DISK

--------------------------------------------------

A pass-through disk is a physical hard disk on the host that a virtual machine can use instead of using a virtual hard disk. You can use Convert-SCVirtualDiskDrive to convert a pass-through disk attached to a virtual disk drive on a virtual machine to a virtual hard disk. The virtual machine must be on a Hyper-V host, and must be in a stopped state before you can convert the pass-through disk to a virtual hard disk.

  • VirtualDiskDrive

Examples

1: Convert a pass-through disk on a virtual disk drive on a virtual machine to a virtual hard disk.

The first command gets the virtual machine object named VM01 and stores the object in the $VM variable. This example assumes that VM01 is currently configured to use a pass-through disk and that the virtual machine has only one pass-through disk.

The second command gets the virtual disk drive object on VM01 and stores this object in the $VirtDiskDrive variable.

The last command converts the pass-through disk drive stored in $VirtDiskDrive to a fixed virtual hard disk and moves the virtual hard disk to the destination folder "C:\VirtualDiskDrives".


PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"PS C:\> $VirtDiskDrive = Get-SCVirtualDiskDrive -VM $VMPS C:\> Convert-VirtualDiskDrive $VirtDiskDrive -Fixed -Path "C:\VirtualDiskDrives"

2: Convert one of several pass-through disks on a virtual disk drive on a virtual machine to a virtual hard disk.

The first command gets the virtual machine object named VM02 and stores the object in $VM. This example assumes that VM02 has three virtual disk drive objects and that the first virtual disk drive is bound to a virtual hard drive whereas both the second and third virtual disk drives are bound to pass-through disks.

The second command gets all virtual disk drive objects on VM02 and stores them in the $VirtDiskDrive object array.

The last command converts the third pass-through disk ($VirtDiskDrive [2]) to a dynamically expanding virtual hard disk and moves this new virtual hard disk to the destination folder "D:\".


PS C:\> $VM = Get-SCVirtualMachine -Name "VM02"PS C:\> $VirtDiskDrive = Get-SCVirtualDiskDrive -VM $VMPS C:\> $VirtDiskDrive[2] | Convert-SCVirtualDiskDrive -Dynamic -Path "D:\"

3: Convert a dynamic VHD attached to a virtual disk drive object on a virtual machine to a fixed format.

The first command gets the virtual disk drive object that is attached to virtual machine VM03 and stores the virtual disk drive object in the $VirtDiskDrive variable. This example assumes that the virtual machine has only one virtual disk drive object and that the virtual hard disk attached to the virtual disk drive is a dynamic virtual hard disk.

The second command converts the virtual hard disk stored in $VirtDiskDrive to a fixed disk.


PS C:\> $VirtDiskDrive = Get-SCVirtualDiskDrive -VM (Get-SCVirtualMachine -Name "VM03")PS C:\> Convert-SCVirtualDiskDrive -VirtualDiskDrive $VirtDiskDrive -Fixed

4: Convert a dynamic VHD attached to a virtual disk drive object on a virtual machine to fixed VHDX.

The first command gets the virtual disk drive object that is attached to virtual machine VM03 and stores the object in the $VirtDiskDrive variable. This example assumes that the virtual machine has only one virtual disk drive object and that the virtual hard disk attached to the virtual disk drive is a dynamic virtual hard disk. This example also assumes that the virtual machine is in a stopped state.

The second command converts the virtual hard disk stored in $VirtDiskDrive to a VHDX disk.


PS C:\> $VirtDiskDrive = Get-SCVirtualDiskDrive -VM (Get-SCVirtualMachine -Name "VM03")PS C:\> Convert-SCVirtualDiskDrive -VirtualDiskDrive $VirtDiskDrive -VHDX

5: Convert a differencing VHD attached to a virtual disk drive on a virtual machine to a differencing VHDX.

The first command gets the virtual disk drive object that is attached to virtual machine VM04 and stores the object in the $VirtDiskDrive variable. This example assumes that the virtual machine has only one virtual disk drive object and that the virtual hard disk attached to the virtual disk drive is a dynamic virtual hard disk. This example also assumes that the virtual machine is in a stopped state.

The second command converts the differencing virtual hard disk stored in $VirtDiskDrive to a differencing VHDX disk. Additionally, this command deletes the source disk.


PS C:\> $VirtDiskDrive = Get-VirtualDiskDrive -VM (Get-SCVirtualMachine -Name "VM04")PS C:\> Convert-VirtualDiskDrive -VirtualDiskDrive $VirtDiskDrive -VHDX -BlockSizeBytes 1MB -DeleteSource -ValidateOnCompletion
