Expanding a VMWARE virutal disk over 1TB?

I need to expand the virtual disk on a  VMware Guest OS to over 1TB. I am using VM converter 4.0 to expand the virtual hard disk inside the volume. The maximum size that I am allowed in the VM converter is 1000GB. I need it to be 1300GB. I am able to have a volume that is over 1TB if the sum of all the volume are over. IE. I can have a volume with three virtual disk 800GB, 400GB, and 400GB with a  total  volume of 1.6 TB.

I need a virtual disk that is 1200TB in side. Is this a VM limitation on Virutal disk? How can I do this is it is not a limitiion?

If you configured your datastore with a less than 8MB block size when you added it to your host, you have this limitation. I believe that's why you're having a problem when you use the Converter. It's asking where you want to place your VM, correct?...like, on what datastore? When you select which one, if that datastore was added to your host with <8MB block size, that is why. When you add datastores to your host, you have 4 block size options -> 1MB, 2MB, 4MB, and 8MB block sizes to have a max VMDK of 256GB, 512GB, 1TB, and 2TB respectively. You can reference this info in the Config Max Guide here:

...specifically, on pg. 3.

Since the size you're wanting is > 1TB, I recommend not using converter for that volume, anyway. It would be better to just add a virtual disk to your VM, initialize & format it, then use something like Veeam FastSCP (http://www.veeam.com/vmware-esxi-fastscp.html) to copy or move the data to your other VM. (I think Veeam is a bit quicker than standard Windows copy/move & paste)

Coolsport, Sorry it took me a while to respond back but got sidetracked.

The VMFS are configured with 8MB block. The limitation come from the actual VMconverter. I actually spoke to Vendor and then suggested that in a physical hardware environment that they would harddrive and with the Windows utility span the harddisk. So I need to figure out who to add an aditional virtual disk to the VM. I am going to be asking this as another question.

FYI We have used VEAMFAST SCP in the past. This is not the route I want to take though. Watch out for the other question. will award the 500 point for quick response and solution in 2nd comment theorectically could work.

Could theoretically work in my case but not the route I want to go.
