As you can see, there is no ./target/ibmvscsis directory created. In order I suspect something like that.

As I said long before, this kinda hardware configuration should automatically show up when we load the driver module. But the target core is broken in this regard. Anyway, I'll fix the driver not to crash with incomplete configurations.
