Default Missing drive in /dev, but shows in dmesg

Hi, I have a big pile of 1U boxes that are getting OpenBSD and I have run into a weird problem that is probably easily explained by someone who is more current with OpenBSD than me!

I boot a 4.7 install CD (or tftp) and dmesg shows sd0 and sd1 -- the 2 32G Corsair SSDs I have -- and I usually like to dd them first thing:

dd if=/dev/zero of=/dev/rsd0c bs=1024000

And this works fine for sd0, but /dev/rsd1c doesn't exist. In fact, nothing related to sd1 exists in /dev. But it was in the dmesg.

What am I missing? It's annoying to boot into a Debian rescue disc just to dd since it sees the drives as sda and sdb and can dd without any problems.

After the install, sd1 works fine and is used to complete a software RAID1 which goes off without a hitch. I don't think there are hardware problems.
