Not "tray". "target". individual disks are generally one drive per
target (so you see cXtYd0). A raid controller may have multiple
logical units distinguished by the "d" number.
with WWN-based target names, the Y is in uppercase hex (to avoid any
ambiguity when you hit the lowercase "d'); everything else is decimal.
