The E450 has a potential of 20 internal disks, none of them labeled in any particular order (ctd numbers) and it was a pain to configure most of them as a big stripe.

Here’s the md.tab I created, note the u02 section showing how to string 7 disks (slice 2 is the whole disk) all together. Note that the line wraps aren’t shown so don’t recklessly copy and paste.
