Extend the VMDK, then use something like Dell's ExPart to extend the OS partition.

Extend the VMDK by just increasing the disk size of the guest?

With 2003 this is a bit trickier than later OS's.

Extend the partition within the settings of the virtual machine in the VI console.

From within the guest OS, launch disk manager and do a rescan of the disks. I wouldn't resignature if prompted.

Then you require a third party software that supports extending server partitions (there's a LOT of free stuff but none I am aware of that does servers).

Acronis do a reasonably priced one.

Of course, given the nature of the work you're going to carry out, make sure you have a backup/snapshot first.

It would appear that the Dell expart software can do 2003 partitions, so it'd be a good place to start after extending in the virtual machine properties.

Hi

First you need to increase the disk on the VMware side.
If there is any snapshots on that VM, you cannot change disk size. You need to delete that snapshots.
You should backup your VM with a proper Virtual Backup tool. Snapshots is not an option in this case.

VMware KB how to:

http://kb.vmware.com/kb/1004047


It depends on your Windows. For Windows 2003/2000 or XP you can use diskpart on the Windows Side.

In Windows XP and in Windows 2000, you cannot use Diskpart.exe to extend a simple volume on a Dynamic disk that was originally created on a Basic disk. You can extend only simple volumes that were created after the disk was upgraded to Dynamic disk. If you try to extend a simple volume on a Dynamic disk that was originally created on a Basic disk, you receive the following error message. This restriction was removed in Windows Server 2003.

Also you cannot use Diskpart on disks that have the system page file on the same partition. You need to use a 3trd parties Partition Tools to extend the disk, or you need to migrate the system page file to another partition that you are not extending.

You need to use a 3trd party Partition Tools

I use gparted and work ok

http://sourceforge.net/projects/gparted/files/gparted-live-stable/

For Windows 2008, vista and 7, you do not need to use any 3trd party Partition Tools, you can extend the disk on Windows side in the Windows Disk Management.

Just extend the disk, after you have increase the disk in the VMware side. You may need a reboot after extend the disk in the Windows side.

Hope this can help
