powershell script for expanding c drive in Vmware VM and extending the disk in same script

Can anyone help in extending the c drive:disk1 in vmware VM and extending the c drive in same script.
I am able to extend the disk via powercli with oneliner script but challenge is extending the c drive in windows without using diskpart diskmgmt.


Thanks

Powershell 3.0 in Windows 8.0 and Windows 2012, has supported for re-size partition

Get-PartitionSupportedSize and Resize-Partition functions can be used.

What is your OS?

Thanks Andy. I need to extend the c drive for multiple VMs on ESX.majority of these hosts are 2008 and I need a script for carrying on this task along with extending the disk

Personally, we would do it manually, and check all is okay, and make sure you have a full backup before you attempt this, as re-sizing often goes wrong in the OS. (not a snapshot!).

We would never attempt to write a powershell script to extend the disks, and OS partitions, that is asking for trouble, as so much can go wrong, and usually does manually, and then we only ever re-size a disk, by checking the existing resources, e.g. datastores, are not going to be low, e.g. less than 25-30% storage space.

I can only agree to that. I would not try to automate this action, at least not without including the backup - and that requires you to mix up outband and inband PowerShell code, making ti more complex than it is worth it.

Doing this in an automated fashion is a bit scary but if you are doing this in a test or have do other choice you could write a batch file that would call diskpart -> list volume -> select volume x - >extend...

I would then create a computer group policy to run the script since a computer policy would run the script as the local system account
