I received a ton of replies. Many thanks to everyone. The consensus was
that Yes, this mirroring will work as long as submirror 2 is slightly
larger. And it did work flawlessly. The only caveat is that if I lose
submirror 1 (the smaller disk), I'll probably need another 18GB drive to
restore the mirror pair. I'm cool with that because we have a bunch of
18GB spares here doing nothing.
Thanks gang and cheers.

Subject
mirror 2 different geometry disks?
I have a 9gb and an 18gb drive in one of my E10K's D1000. I'd like to
disksuite them up for a more fault tolerant boot pair. The 9gb drive is my
current boot drive. But when I try to fmthard the 18gb drive, it complains
that the sector ends not at the cylinder end or something. So I got it
partitioned as close as I could manually. Can I mirror these up with
disksuite still even though the geometries are not exactly alike? I've
made the new disk partitions slightly bigger than the original.
