Also, what kind of hardware are we talking about? We need to know the types of buses involved (SATA/SAS/FC), pool topology and port configurations where applicable. For example: if you are trying this on your home PC box with SATA ports in IDE emulation mode, I can tell you right away that hot-plug won't work. IDE doesn't support that, you'll need to switch your SATA ports into AHCI mode for that to work.
