Rich, I got diskmap.py downloaded and tweaked to work on my system.  
Looks good so far.  The rackables enclosure has 16 slots in a 4x4, 
numbering from 0 (top left) across and then down, so bottom right is 
15.  I got this after discover&disks:

The 6 tank drives are in the middle of the enclosure, taking up a 2x3 
sub-matrix.  By the chart I worked up, that is slots 1, 2, 5, 6, 9 and 
10.  You can see the controller number is 0, the enclosure number is 2 
and the disks are 1, 2, 5, 6, 9 and 10 :)  I did see this during probe:

Diskmap - openindiana> discover

find it in disk detected by sas2ircu (disk removed/not on backplane ?)
Warning : Got the disk /dev/rdsk/c2t5000C5000D3C80FFd0 from zpool 
status, but can't find it in disk detected by sas2ircu (disk removed ?)

Note the drive it is bitching about is the 500GB SAS root pool drive, 
which is NOT in the enclosure, but plugged into a forward breakout cable 
on the 2nd port of the LSI controller.  The only reason for this is it 
is a 2.5 inch drive (the tank drives are all 3.5 inch).  I got an icy 
dock 2.5/3.5 adapter but it only takes SATA drives :(  So it is slated 
to take the Crucial M4 256GB SSD to be L2ARC.  I would like to get the 
root drive moved to the enclosure, but it is not a high priority.  Thanks!
