I am in the midst of setting this up on C-5 attached to a MSA1000 running 
active/passive.  The documentation is... sparse, to say the least. 
There's more than a bit of guesswork in my setup, and I have yet to 
actually test the failover.  I certainly think it'd be worthwhile for you 
to document your experience somewhere.
