BTW, the only change you get with "ndd -set ip_enable_group_ifs 0" is that the addresses are no longer rotyated; instead a random one is picked. Work around:
This looks like it might do the trick. I haven't tested it yet, but, theoretically if you do the above ndd and then put each IP into the NetApp's /etc/exports file, it should work.
Would certainly be nice if Sun would let you turn that "bug" off and also let you specify which of the virtual ip's should act as the source IP.
