Tim,
Thanks for your quick help on this! I don't care about the old data at all, so I've just done the dfm host delete -f ... stuff to nuke all our old NetApps, and mis-named ones aswell.
From what I see, DFM 3.0 doesn't support the command
dfm host rename ...
But it's certainly looking better now. Though I need to get SNMP turned on properly too still.
Is it me, or is DFM (the gui at least) a piece of junk? The CLI commands actually make sense... the GUI is just bonkers.
John
