It seems to me though that I have done precisely that: I have a created an LACP channel (a0b) and then assigned (4) links to it (two from each controller). I want to present to the switches a single LACP System Identifier + Key, so that they perceive the ONTAP cluster as a single entity.
Are you suggesting that I want (2) channel-groups, each containing (1) port from each controller? e.g. something like:
network port ifgrp create -node ontap-n1 -ifgrp a0b -distr-func ip -mode multimode_lacp
network port ifgrp create -node ontap-n2 -ifgrp a0b -distr-func ip -mode multimode_lacp
network port ifgrp create -node ontap-n1 -ifgrp a0c -distr-func ip -mode multimode_lacp
network port ifgrp create -node ontap-n2 -ifgrp a0c -distr-func ip -mode multimode_lacp
network port ifgrp add-port -node ontap-n1 -ifgrp a0b -port e0d
network port ifgrp add-port -node ontap-n2 -ifgrp a0c -port e0d
network port ifgrp add-port -node ontap-n1 -ifgrp a0b -port e0f
network port ifgrp add-port -node ontap-n2 -ifgrp a0c -port e0f
