Why not drop power? (see test scenario in previous mail)
There are lots of cheap ways available to do that.
I personally keep my test machines on cheap USB power switches and can switch them any time. It will probably lower the MTBF of your test boxes somewhat though, but that's the price for good testing.
The concern, as you mentioned above, is that you wear the equipment out with this kind of thing. Power supplies are probably the most impacted ;-)

Just a personal note, my last day at EMC was this past Friday. Monday,
I start working for Red Hat (focused on file systems) so I will have
to figure out to get this kind of test going without all of my big EMC
toys ;-)

Congratulations on the new job. I don't think you need any big toys though.
