Help with a Clariion 4500 (aka dell fc450) raid array

[bad bob <sfmc68 () bellatlantic net>]

Attempting to recover from a helpful person who seems to have caused the 
clariion to be some kind of
lump of metal - none of the drives are visible - running the management 
tool for the box does not seem to
provide the command capability to help it recover.
My thoughts were that the serial console port may be a path to find out 
what is going on in the box.
So far, I have been able to occaisionally see the system status as it 
boots but I have not been able
to get the box to respond on the console side.

Now, why am I asking here?  This is a slightly different box than the 
usual EMC.  What I am interested in,
is whether or not one can get to the data, via cache or other means, on 
one of these boxes. how you could
cause a denial of service (seem to have accomplished that), and how you 
can recover from a DoS if it does
happen.  As more and more folks stand up EMC boxes to store data, what 
do we know about them>
thanks
