This isn't a type of problem I've had to deal with before so I'm not
sure if I can help...

But just wondering:

1)  Have you tried creating a hardware RAID of just 4 disks instead of
6.  Does it work?  I mean, assuming the drives are new and empty, you
can always give it a try and then reconfigure them later.

2)  If it can build a hardware RAID of four disks or less, is there an
issue of connecting those 6 drives to it?  For example, could you
create two RAIDs -- one with 4 drives and another with 2?

I've only built a software RAID once and my experience with it was
negative.  (Granted, it could also be because I'm inexperienced.)  So
that's something I wouldn't know how to do or know the pros/cons of...
