Does anyone know if this would affect current mounts if we just enable it at the filer command line with "options nfs.tcp.enable on", or can that be done? Is it a fairly transparent thing or should we schedule down time?
Down time? Heavens no! The words "down" and "time" are considered very ugly around these parts when used adjacently. :-)
I had no reason to believe that this would not be the case, but just to be on the safe side I did a little double-check on a filer here for you, and sure enough you have nothing to be afraid of. Go ahead and enable TCP at your leisure...
