This can happen if the daemon isn't correctly listening for requests either
because it's still starting up, because it's dumping core or for some other
bug. Did it produce a core file? If you haven't already, I strongly suggest
you configure coreadm(1M) to enable the global core file repository and
then check to see if you get any core files from the iSCSI target daemon.

This sounds like a bug in the iSCSI target. There have been several fixes
in this area recently -- what build are you running?

ZFS stores its iSCSI configuration information as a property of the zvol
dataset (that is, not in the xml file in /etc).

Any details you can provide would be very helpful. If you want to file a
bug directly with that information, that would be even more helpful.

Sorry you're finding the transition a bit rocky. We've been working to
improve the iSCSI target, ZFS, and their interactions.
