If you are installing on them there are a couple of ways
you can do it in the diskdruid GUI.  I've only done RAID1
but the approach should be the same.  Create the per-disk
partitions you want first, setting the type as raid, then
select them and create the raid set with the mount point,
filesystem type, and raid level.

If you have a working system and are adding new drives, fdisk
the partitions, setting the type as FD (raid autodetect), then
create the raid with 'mdmadm --create ...'.  There are some
examples shown in 'man mdadm' (yum install mdadm if you don't
have it).  Then make the filesystem on the md device you
just created and mount it.  Be sure you understand that you
multiply the chance of disk failure by the number of
drives in a raid0...
