Yes, I first started by setting up the raid and installing openBSD on
top of it. All was fine until one of the disks failed. Then, I replaced
the failed disk, and try to re-initiate the raid (mirroring) where I got
stuck since the raid controller did not like the partitioning.

However, I advanced one step further now: If you use fdisk to assign a
different id to the openBSD partition (like 83 as suggested by Sun for
the Linux installs), raid controller seems to start mirroring your disk
to the second one. However, when you change your partition id from the
default value of A6 to 83, openBSD could not boot. So, I am planning to
play with the partition id so that I could set up the mirroring through
LSI raid controller. Once it is done, I will revert the partition id
back to its default value of A6. Then I will see if mirroring still
works, and boots off of the second disk!

At present, I've got two LSI RAID controllers here running OpenBSD

Though I don't know about your specific controler (1030), the normal
answer is to create your logical drive in the controler setup and
*THEN* install the operating system.

From your description, it seems you're doing things backwards, namely
installing the OS on one drive and then trying to create a miror.
