Correct. However, I think Wolfgang thought d90 was already a mirror,
but I'm not sure.

I agree. However, I inherited this system without a mirror in place
(probably because the real RAIDing is being done on the backend with
the SAN device), and am just trying to get some maintenance done on
it. My thought was to try and mirror the old SAN disk to new SAN disk,
thus reducing downtime and ensuring accurate transfer of data.
