Unable to add a physical disk to a virtual machine in Hyper-V

We are trying to add a Physical Drive to a virtual machine in Hyper -V. The VM can see the drive when it is running.  The drive set as offline in disk management, But when we shut down the VM and try to add the physical drive in Hyper-V when the physical disk option is grayed out.
We had this drive setup as a Physical drive before but became disconnected when we deleted old snapshots of the server. The virtual machine now reads the disk as an IDE drive is there anyway to get this back to a physical drive?

To clarify a little bit. We had pass through drive set up on this Virtual machine using iSCSI. We set it up as a SCSI drive in the VM. We retired a snapshot and when we restarted the VM the SCSI pass through drive was missing from settings. The Virtual machine still shows the drive we created but it is using the ide controler. We've offlined the drive and tried to re add it but it's not allowing us to add a SCSI drive.

It would be faster to actually add the iSCSI disk in the VM itself, and completely bypassing Hyper-V's pass-through disk.  You're removing a layer of complexity and improving performance.

If this is not possible (guest OS does not support iSCSI), then read on.

Hyper-V cannot operate snapshots on Virtual Machines with Pass-through disks.  In fact, it shouldn't have even allowed you to add the virtual disk in the first place with a snapshot in place, nor should it have allowed you to create a snapshot with a pass-through disk.

Check the following:

Can you see the iSCSI Disk in Storage Manager on the Host?
Is it marked as offline?  Disks are always offline until the Host starts the VM, and then it will mark it online when it presents it to the guest.
Try to add the offline physical disk to the VM.

We gave up on the pass through drive and built a physical location for our software.
