I have a netapp with several shelves that is going to have to be moved. Various servers have NFS mounts from it. What is the proper procedure to shut it down and start it up? I would guess shutting down the servers before the netapp and then the otherway when starting it up would make sense... what about the netapp itself?
As far as the filer itself, "halt" from the CLI is pretty much all you need to know. (You'd obviously want be sure that no servers are using it). Power off the head, then the shelves, and do in reverse after you've moved.
http://now.netapp.com has some valuable best-practice guides for this sort of scenario - as an aside, if you're physically moving the netapp, it would be very wise to make sure that your netapp support is current.
Shutdown - Perform steps on both heads of the filer
If the numbers are not close to zero determine why there is traffic.
