My initial feelings are 'bad things will happen'.

I dont have any technical data to back that up, other than its not documented to do it that way.

We are going to be adding an additional FC shelf to our clustered F740's. Obviously, the safe way to do this is to halt both 740's, attach the A & B loops, then bring both filers back up.

But, what I was wonder was, would it be possible to:

- Attach the B-loop first. - Have the B-Loop Filer take over all th shelves (including the new shelf). - Attach the A-Loop. - Give back the shelves to the A-Loop filer.

I don't think we'll do this as we're only talking about about maybe 2 minutes of downtime vs 30 seconds, but I was wondering if this is a feasible thing to do.

Thoughts?
