Add Storage to VM

I have inherited a some vwmare 3.5 servers with a Fibre SAN carved into several datastores. I want to ultimately add space to one of my windows 2003 server's drives. When I look at the datastore inventory it shows almost 20GB of free space. When I edit the settings of the VM it does not show that I can increase the size of the virtual disk. ie - disk size and maximum size are the same.

Other machines with different datastores show free space and the availability of that space to the virtual disks.

Hi,

ESX 3.5 does not allow online expanding of disk spaces when the Guest is running. Also it does not allow the expansion of volume when there are any snapshots associated with the VM.

So make sure that you remove all snapshots and make sure your VM is shut down before trying to increase the virtual disk size.


Cheers,
K.

I don't want to add a disk, I just want to expand the one I have. I am battling with free space, and this is a temporary fix until I can get some new servers.
The disks are SCSI and part of Fiber array.
I have attached a PDF with some screenshots.
