Increase VMware Vcenter server disk space using powershell

Increasing virtual disks in VMware is pretty easy and straightforward.
Mapping them to the right disk in your computer is hard. They have not direct correlation seen in the Vmware ui.
So its pretty much guesswork after checking the available diskspace in computer and matching it with the diskspace seen in VMWare.

This script matches the disks in VMware with the one in computer.
Increases the space
Extends all the partitions in your computer which have free diskspace.You shouldn't have diskpace lying around unused anyway ;)

Things you need.
Account which has rights on the VMware server. Account with rights on your computer.
VMware assemblies or powercli installed.

 If your script fails with and exception for SoapInterceptor
find the dll VMware.VimAutomation.Logging.SoapInterceptor.dll in your powercli install directory.
and add this line to your script after placing it in the right location.
