Hi, this seems exactly like a job for my half-baked procedures (manual work needed during setup) to wrap each pool, zone and iscsi service into SMF instances so you can set up dependencies for ordered startup-shutdown.
The first two I use on a number of machines (Solaris 10, OpenSolaris Nevada, OpenIndiana and now starting with OmniOS). Don't have much iscsi beside initial experiments though...

Hope this helps,
