FYI, when you have LOTS of clients, you have better distribution from the NetApp using "port" instead of IP --tmac

Yes thanks to John, I went away and had a look at configs, and yes Michael correct, the LAG was not up across the switches!
I had a rethink, on the MC-LAG between the switches as these use VLT
And I'd left a command out!
So this is, with the correct command
vlt port channel 1
Thanks for the sounding board guys!
Re-test later today against the test-plan, still not sure how it was working before!

On the Dell side, you'd need to configure VLT on the port-channels in order to have both switches participate the same LACP bond. Assuming they're running DNOS10, here's the link to the config guide: https://www.dell.com/support/kbdoc/en-us/000102901/dell-emc-networking-os10-... .
Thanks, Michael

Ah! I think I see the reason for Partial now
Although, not sure how this is working against the test plan!

And those Down Ports, or though appearing as up on the switches, are on the second switch, so the LACP port channel is not LAG across both switches.

Anyone here on this list familiar with Dell 4840-ON and Port Channel LACP configurations with two node FAS2820
Not with the Dell side, but the Netapp side.
Usually by network is good (he says! 😊
So what's your configuration look like?
It’s definitely not working as expected, e.g. fail a port and access is lost, so somethings not right, and I’m wondering if the SVM which is attached to current port e1a, is the issue, and it should be connected to the trunk a0a, or a0a-2033 – the VLAN
We need more details. But start at the bottom. Can you show:
ifgrp show -instance
The key would be to see if the LACP policy agrees on both ends.
