Interesting. Noted!

I'm trying to gather hardware to experiment with FreeBSD + hast + ZFS +
istgt (iscsi target) on the storage end.

For this to work, istgt has to support adding new storage without a full
restart (I think it does), and the NetBSD iscsi initiator must be able
to play nicely with istgt (did some preliminary testing the other day,
and netbsd's iscsi_initiator core dumped on connecting to istgt.. didn't
troubleshoot it further).

I think this is an interesting topic to tackle.

Another thing that crossed my mind is how will netbsd (dom0) react to
temporary loss of connection to the storage..
