Cant Create Large GPT Spanned Volume

I have a Windows 2008 R2 server that is a VMware virtual machine. It needs a 17 TB volume that will be used as a backup to disk target.

I don't see a way to present more that a 2 TB LUN to it, so I have presented 9 LUNs (8 x 2,047,870 MB + 1 x 520,978 MB) to the OS.

I have converted them to GPT.

Now I am trying to create a spanned volume.

As I add the disk to the New Spanned Volume wizard, the total volume size increases, but the maximum available space does not increase above the size of one LUN (2,047,870 MB).

What am I doing wrong?

You are running basic disks they should be dynamic

I have tried it both ways. I will convert and try again.

I followed the directions in one of your posts that had you go through each disk in diskpart and:
select disk <#>
clean
convert gpo

That reset them back to basic.

Could me a hardware limitation.

I don't see how. The OS sees the LUNs. A spanned volume is a function of the OS. If I tried, I am sure I could create 9 simple volumes out of those LUNs.
