Configuring Pass-through Disks in Hyper-V

一些要点:

1. To ensure the Guest has exclusive access to the storage, it must be placed in an Offline state from the Hyper-V server perspective.

2. Additionally, this raw piece of storage is not limited in size so, hypothetically, it can be a multi-terabyte LUN.

3. Configure high level steps: Online->Initialize Disk->Offline->Add to VM

4. If a Pass-through disk, being used to support an operating system installation, is brought Online before the Guest is started, the Guest will fail to start.

5. Be aware that Pass-through disks cannot be dynamically expanded.

6. Additionally, when using Pass-through disks, you lose the capability to take snapshots.

7. Finally, you cannot use differencing disks with Pass-through disks.
