Sorry, let me give my conditions a bit more: I don't think I can reboot
the server - I believe it's currently in use as a development machine by
one of the teams, so I can't play around with it.

I believe it's the same kind of controller, so that's ok. I'm using MSM
for the above reasons, and that the cli isn't installed.

Playing with this thing, I believe I want to create another drive group,
not just add another RAID to an existing one, which just seems as though
it could get really ugly. But when I click on the controller, I can then
get to "Go To" -> controller, which will let me create a new virtual
drive, but drive group is all greyed out still. Further, I don't see
anything that would let me investigate what the documentation seems to
call a "foreign RAID".

Hope that gives y'all a better picture of my environment.
