Plan carefully how you are going to create the vdev's before you add them to a pool. Once a vdev has been created and added to a pool, you can't ever un-add and/or replace them. (You always can replace a component of a vdev -- e.g., if one physical drive fails -- but you can't remove a vdev in its entirety).
