Then log on to the console of the Host server

Change to the directory that contains the VMDK (you can just pass the full path to the command line but I find this less confusing)

Type the command: vmkfstools -X <size> G <VMDK file name> (note that G stands for gigabytes so to expand a disk to 32 GB it would simply be vmkfstools -X 32G some.vmdk).

Type ls -lh and you should see the VMDK is now that size.

At this point you must use the OS tools to in order to see the additional space. I don't kow how this is done in Novel but in Windows I use the 'diskpart' tool.

Good luck

p.s. of course you make a backup first

anyhow, the command line description is way faster when u know what you are doing ^^
