BUT BUT BUT - there is no way to clear the devices nodes from FreeBSD!
If I attempt a "camcontrol rescan all" after pulling a set the machine
instantly panics with uncompleted I/Os to the disks I did not tamper
with - whether I tell the adapter I did it first or not.
With the 3ware drivers this is propagated through properly. Not so with
the Areca drivers. This is a fairly major problem in that it appears
that anything you do that causes a "da" device served by these boards to
disappear causes an instant panic. While this is expected behavior if
the device is in active use, it really, really sucks if it's not, as it
makes it flatly impossible to, for example, pull a disk carrier that has
a big drive on it you just ran a dump to.
It may be worth you taking this up with Areca support also. I have a
handful of their cards at work and one at home and had some issues with
the HTTP interface on amd64 recently. They'd got back to me with a
solution within a couple of days.
