FYI: With certain shelves (FC9's?  I forget exactly), you don't need to
shutdown to add new shelves.  The shelves self-terminate, so you don't need
an external terminator on them.  Adding a new shelf?  No problem, put it in
the rack, insert the disks, plug the power cables in, hook the FC-AL cable up
(new shelf in, then old shelf old).  When you're ready, turn the new shelf
on.  The filer will notice the new shelf and the disks, incorporate them as
spares, and that's it.

I've done this a couple of times now, it's great.  Need another 250+GB of
disk?  Get it up and running with 0 downtime.  :)

6.0.x is supposed to get that down to under 45 seconds.  They're aiming for
"5 9's" of uptime.  ;)
