Anyone correct me if I'm wrong but if im not mistaken, for you to setup a
RAID 10, you have to use the SPAN (i.e. CANSPAN) option in Ctrl-M when you
are setting up your Raid arrays.
Exmaple, if you go into Ctrl-M, select: Configure --> New Configuration -->
Proceed "Yes" --> Hit spacebar on two Hard drives (ID#0 and ID#1), then hit
spacebar again on ID#2 and ID#3. Hit ENTER twice. Now, in the Logical
Drive "00" box, you have an option for Span = xx (xx = yes or no). I
believe this should resolve your issue.
