hardware RAID is invisible to the OS itself.

I wonder if the RAID array isn't still getting itself online - it takes
quite a bit of time depending upon the number of drives and the
speed/size of the drives. I believe the process is called scrubbing.

The last time I set up a RAID 10 was on a 6 drive RAID 10 (perhaps it
was called 1+0) on a Dell MD-1000 and I went to lunch and shopping
before I came back to install.

It's likely that the RAID array isn't available for installation until
the process is completed.


  I configured RAID 1 in the next attempt and now F10 detects my RAID array.
