After reading further in my manuals, I've got some questions about the RAIDgroup size.
When I initially created the volume, I made the raidsize 14, so that it would use 1 parity disk for the 14 disks we had at that time.
Looking at it now, I kind of think that I want a raidsize of 13 for the current volume (since one disk is a hot spare).
So, I issued: vol options vol0 raidsize 13
That worked ok, because now:
vol status vol0
Volume State Status Options vol0 online normal root, raidsize=13 raid group 0: normal
Basically, what I'm trying to avoid here is having the first 36gig disk added to the initial raidgroup. I believe changing the raidsize to 13 will have fixed that, since now that raidgroup is full, and additional disks will go into their own raidgroup.
I welcome (and request. :) all comments on this post.
Thanks very much, Jordan Share

As I understand it, I would then have 2 hot spares (18 and 36), and two drives for parity.
Yup.
You would need the separate spare to accomodate the difference in drive sizes. The parity drive is a function of RAID 4.
We did the same about a year back on our 740 and it worked well.
Are there any "gotchas" (or blatant ignorance on my part) in
this scenario? It was mostly smooth. Though you might need to upgrade your ONTAP version to 6.1.1R2 atleast
