I've got a machine with two drives 120gb drives, which is going to a
colo.  If I configure it to use one drive, will I at some point be able
to remotely reconfigure it to say use the second drive as a mirror as
the physical layer, i.e. if the first drive goes bang then I can get the
second drive to boot via the bios and still have the machine work - or
am I dreaming?
