gmultipath, ses and shared disks / cant seem to share between local nodes

[Outback Dingo]

Ok, maybe im at a loss here in the way my brain is viewing this

we have a box, its got 2 nodes in the chassis, and 32 sata drives
attached to a SATA/SAS backplane via 4 (2 per node) LSI MPT SAS2 cards
should i not logically be seeing 4 controllers X #drive count ??

camcontrol devlist shows 32 devices, daX,passX and sesX,passX

we would like to create a zpool from all the devices, that in theory if
nodeA failed
then nodeB could force import the pool, nodeA and NodeB are attached through
dual LSI controllers, to the SATA/SAS backplane. but i cant seem to create
a zpool from sesX or passX devices, i can however create a 16 drive zp0ol
on either node, from any daX device. what did i miss? ive looked at
gmirror, and also ses documents. Any insight is appreciated, thanks in
advance.
