For anyone who cares about my saga so-far ;-) ... I got physical access to the unit this morning and setup the drives as 15 RAID-0 Logical drives and booted up Linux, and it then attached all the drives in the usual way. And I can see all 15 drives. So the down-side is that I can't use any sort of SMART stuff over the bus (as pointed out by someone else). Anyway, it's currently in a RAID-1 configuration (which I used for some initial soaktests) and seems to be just fine: Filesystem Size Used Avail Use% Mounted on /dev/md9 6.8T 33M 6.7T 1% /mnt And it's more than fast enough too, although it'll be a lot slower when I rebuilt it in RAID-6 mode.
