in short, your hardware RAID is a fake RAID. in linux it means that you have 
access to both the normal disks and the raid array.

the reason for this is that the raid array is sort of a software raid wrapper 
in firmware, but it'll make your raid slower than it would in linux as a linux 
software RAID.

that being said, likely systemd and installer will try to look and use 
whatever disks it can see, it likely doesn't know what the raid is looking 
like and so it likely tries to guess...

that being said, i don't know much about this. i would advise you to file a bug 
report so the people who know about this sort of thing can answer you in the 
bug.
