So does "sestopo" work on your Supermicro system? 
You can also try "/usr/lib/fm/fmd/fmtopo -dV" and "prtconf -v".

The important part is that the backplane SES chip needs to give
disk identification for each slot, so FMA can figure out which 
disk is in which backplane slot.

If that works, then in the event of disk failure FMA should be 
able to match "failed disk is in slot X" based on the SES info
and blink the correct failure LED using SES.

I don't know if FMA has all the needed bits included in opensolaris,
I believe at least Sun Fishworks had that stuff.
