Sit back and just think a minute:
You have a fullfledged hardware raid. You set it up to be a RAID5
array. What do you expect to see?

I would expect to see one HDD, since the Hardware RAID takes care of
all the little, pesky things you need to setup a RAID.

So I state there there is absolutely no problem anywhere.

Go ahead and do everything you like with that sda it your raid.

BTW: Some investigation should have revealed that the capacity of sda
is larger than that from one single disk...
