Try to use partprobe to re-read available disks/partitions. I'm not sure is it available when %pre script runs, but anaconda does that somehow during the partitioning section so I guess it's possible. In the worst case scenario I would add reboot at the end of creation of raid config in the %pre script - so that it would reboot if change in config occured. I know that its rather a nasty hack, not a proper solution, but please keep in mind that anaconda has some limits.
Good luck!

I'm a little puzzled. Years ago (RHL 7.x I think) I used to initialise
disks in %pre with various incantations of dd and fdisk (one can pipe
commands into fdisk). That worked fine, and I'm pretty sure I created
new partitions. fdisk forces partition tables to be reread.
Of course, it's possible anaconda has been broken since then:-)
