I can mount these raids I created in Suse 11 with:
mount /dev/sda1 /mnt/dr1
mount /dev/sdb1 /mnt/dr2

but when I reboot the mount is gone. I have edited fstab with:
/dev/sda1 /mnt/dr1 mount defaults 0 0
/dev/sdb1 /mnt/dr2 mount defaults 0 0

and this doesn't work either.

Can anyone point out what I am doing wrong?

I solved the problem.
The fstab entries:
/dev/sda1 /mnt/dr1 mount defaults 0 0
/dev/sdb1 /mnt/dr2 mount defaults 0 0

should be:
/dev/sda1 /mnt/dr1 ext3 defaults 0 0
/dev/sdb1 /mnt/dr2 ext3 defaults 0 0

which allowed for the raids to be mounted automatically on startup.
