Jason -
I was suggesting you try using advanced priv to run the command.
I'm teaching Cluster Mode Performance in Brisbane, Australia this week.
We used this as an exercise in class today.
It does work in advanced priv:
cluster1::>set -privilege advanced
cluster1::*>network ping -lif-owner vs2 -lif vs2_cifs_nfs_lif1 -destination 192.168.0.10 -disallow-fragmentation true -packet-size 9000
no answer from 192.168.0.10
cluster1::*>set -privilege admin
cluster1::>
I hope this response has been helpful to you.
