Add a disk

I reviewed the docs but didn't see anyway to configure an additional disk. I need to test an LVM role and I need a second disk device. Is this possible?

The issue points only to the project documentation and does not name a file, test, or driver entry point. Start by identifying how the documented driver provisions storage and whether an additional disk device can be represented; done means documenting or exposing a supported configuration that provides a second device for the LVM role test.
