2TB disk not showing in iSCSI Target interface

Being the nerd I am I decided that with my family out of town and a three day weekend on tap I would work on my test environment at home. I decided I would build out something similar to the article (http://blogs.technet.com/b/privatecloud/archive/2012/05/02/let-s-build-a-cloud-with-powershell.aspx).
I decided I would have my management server pull triple duty, since while i have enough network gear to build out 4 networks...sadly i don't have enough network cards...lol...at any rate the basics all went fine. I have four Windows Server 8 servers all happily talking to each other in a their own little domain.
Now I want to present storage to them, three of the servers will be Hyper-V servers and I would like to have the CSV enabled with a large volume. So off to configure my iSCSI target. Following this lovel article (http://blogs.technet.com/b/filecab/archive/2012/05/21/introduction-of-iscsi-target-in-windows-server-2012.aspx) I verified that I had everythign set properly, but when I went into the iscsi mgmt window I did NOT see the second disk in my management server.
for the record management server has two disks, 1 145gb sata disk for the OS, and 1 2tb sata disk destined for becoming iscsi vhd's. Originally the 2tb disk was showing as disk 0, after i moved the cable it now shows as disk 1. Still nothing shows. I can mount the second disk to a folder on C: such as C:\Storage > 2tb disk, but when I attempt to create an iscsi vhd in that mount point I'm still only able to create a disk that is the same size as the free space on C:.
Is the software not picking up the mount point properly? is that why i'm only able to create a vhd smaller than C:?
I'm working on this right now so if anyone has any thoughts that would be wonderful. Also, I just checked
Disk 1 is a dynamic volume and is initialized as GPT.

Monday, May 28, 2012 6:20 PM Well until someone can confirm this I'm going to assume that the iscsi target doesn't work with GPT disks. After backing up the data I had already on the 2TB drive, I deleted it in Disk Management and brought it back up as an MBR disk. After that I was able to get it to show up in the iscsi management window.

This is not true. If you mean MS target it does with with GPT volumes just fine.

vr38dett, my experience with setting up windows 2012 iscsi target is otherwise. As soon as I flipped the bit to MBR the disk showed up in the iscsi management interface. I've not had a chance to play with the target software from Microsoft on a Windows 2008 box, so maybe there are differences there.
if you have experience otherwise i'd like to know how you configured your drives to get that to show, so i can see where i went wrong.
thanks,

1. If you run get-disk from powershell cmd window, do you get both disks?
2. What file system do you formatted to for the 2TB drive?
3. If you run new-iscsivirtualdisk <path> -size 1GB, where path points to the 2TB drive, what do you get in return? this is to try create a small VHD on the 2TB drive, I'd like to see if it is a volume iSCSI target support.
