I have a vmware disk with an extended partition and I have just added 20G from the SAN.  I would like to use diskpart to expand the entire partition to include the new 20G.

At a command prompt, type diskpart
Type list volume to display the existing volumes on the computer
Type Select volume # where volume number is number of the volume that you want to extend.
Type extend to extend the partition the remaining free space

DISKPART > extend
The volume you have selected may not be extended.
Please select another volume and try again.

I was thinking there was a problem with extending an extended partition.....?

Perfect.  Per the second thread  "you need to first extend the disk at the hardware level."  How would this be accomplished?

Make sure the VM is off, then within the VMware Server's web management console select the disk which you want to extend, select edit, and if you originally made this a "disk" to use VMWare's SCSI controller, you can just select "Increase Capacity".

How does your Windows detect the new space? When you get to Windows Disk Management is the space block located on the same drive?
