1. First, you have to determine the Storage-Repository-UUID:

xe sr-list 

-> write down / take note of SR-UUID of the SR to delete

2. Find the corresponding Physical Block Device (PBD):

xe pbd-list sr-uuid=your-SR-uuid

-> write down / take note of PBD-UUID of the PBD to unplug and delete

3. Unplug the PBD:

xe pbd-unplug uuid=your-PBD-uuid

4. Delete PBD:

xe pbd-destroy uuid=your-PBD-uuid

5. Delete the association of your SR and the PBD:

xe sr-forget uuid=your-SR-uuid

Hope that helps.

Best regards,

Thomas
