Expand-SCVirtualDiskDrive

Expands a virtual hard disk attached to a virtual disk drive object.

Description

The Expand-SCVirtualDiskDrive cmdlet expands a virtual hard disk attached to a virtual disk drive object in order to increase the total capacity of the virtual hard disk. The virtual machine must be deployed on a host managed by System Center Virtual Machine Manager (VMM) and must be in a stopped state before you can expand the virtual hard disk.

You can use the Expand-SCVirtualDiskDrive cmdlet to expand a Windows-based virtual hard disk file (a .vhd file) attached to a virtual disk drive object on a virtual machine deployed on a Hyper-V host. You can also use this cmdlet to expand a VMware-based virtual hard disk file (a .vmdk file) on a virtual machine deployed on an ESX host. However, you cannot use this cmdlet to expand a virtual hard disk on a virtual machine deployed on a Citrix XenServer host.

Parameters

VirtualDiskDrive

Required? true
Accept Pipeline Input? true (ByValue)
Position? 0 
Specifies a virtual disk drive object. You can attach either a virtual hard disk (for a virtual machine on any host) or a pass-through disk (for a virtual machine on a Hyper-V host or an ESX host) to a virtual disk drive object.

JobGroup

Required? false
Accept Pipeline Input? false
Position? named 
Specifies an identifier for a series of commands that will run as a set just before the final command that includes the same job group identifier runs.

JobVariable

Required? false
Accept Pipeline Input? false
Position? named 
Specifies that job progress is tracked and stored in the variable named by this parameter.

PROTipID

Required? false
Accept Pipeline Input? false
Position? named 
Specifies the ID of the PRO tip that triggered this action. This allows for auditing of PRO tips.

RunAsynchronously

Required? false
Accept Pipeline Input? false
Position? named 
Indicates that the job runs asynchronously so that control returns to the command shell immediately.

VirtualHardDiskSizeGB

Required? false
Accept Pipeline Input? false
Position? named 
Specifies, in gigabytes (GB), the size to which a dynamically expanding virtual hard disk will expand.

Requires a VMM virtual disk drive object, which can be retrieved by using the Get-SCVirtualDiskDrive cmdlet.

Examples

1. Expand a virtual hard disk attached to a virtual disk drive on a virtual machine. 
PS C:\> $VM = Get-SCVirtualMachine -Name "VM01"
PS C:\> $VirtDiskDrive = Get-SCVirtualDiskDrive -VM $VM | where {$_.Bus -eq 0 -and $_.Lun -eq 0}
PS C:\> Expand-SCVirtualDiskDrive -VirtualDiskDrive $VirtDiskDrive -VirtualHardDiskSizeGB 40

The first command gets the virtual machine object named VM01 and stores the object in the $VM variable.

The second command gets the virtual disk drive object located on the first controller ($_.Bus -eq 0) and first slot of that controller ($_.Lun -eq 0) of VM01, and stores the object in the $VirtDiskDrive variable. 

The last command expands the size of the virtual hard disk attached to the virtual disk drive to 40 GB.
