I just got in an F630 with 5.0.2 and four fully-loaded differential shelves. Yowza. It showed up with one volume, vol0, two RAID groups (one for each pair of shelves, I guess), and only two disks in use, in vol0.
I want to live dangerously, with one big volume and one RAID group for it. After all, that's how my other F630's running 4.x are configured, and it's worked fine for a long time.
So naturally I did something stooopid. I (a) added all the disks, except for a spare, to vol0, (b) set the RAID group size of vol0 to 26, and then (c) noticed in the 5.x documentation that setting the RAID group size AFTER the fact don't do squat. :-( I might have had a prayer if I'd done (b) then (a).
Here's what I have now:
pacer> sysconfig -r Volume vol0
RAID group 0

And what I want to have is only one RAID group, 0, with one parity and one spare.
It looks like I am going to have to clobber vol0 and start over. Am I right? Anybody have experience with offlining then destroying vol0?
