Thanks for the advice. The cold swap went great, 6 minutes total downtime! wheee!.

You would have to move the drive shelves from the old filer head to the new filer head anyway, and to do that you've got to shutdown/restart the new filer too. I don't think there's any way to mystically make the new filer advertise the old shelve by "hot moving" them.
If you're running Oracle, Clearcase or SQL on the filers, the problem gets even more risky.
I agree with the others: go for a cold shutdown of the whole system and swap out the filer head itself. You can do it, literally, in less then 10 minutes total, and then you'll be completely done with it.
Good luck chief!

I have an F760 I need to swap out with a new F760. A cold swap would only cause 10 minutes of downtime, but it would be cool setup a temporary cluster and do a takeover with no downtime.
How feasible is this? Would setting up the cluster situtaion mandate a reboot of the filer in question anyway?
