GSM7352Sv1 Netapp LACP LAG
Hey, Trying to configure an LACP LAG with a GSM7352S and our Netapp FAS2020 SAN but I can only ever get one port to come up. We have an 8 switch stack (GSM7352S). We're using 2/0/14 and 2/0/16 ...

I think I got the idea. It only took about 15 seconds of puzzling to figure out what you were trying to show. ;)
Maybe an example switch config from one of our working LACP LAGs will help. I've redacted the VLAN information, changed the names, and changed the port numbers, but the rest is exactly as we're using it.
You might have to order the commands a little differently when entering them, but that is the order it shows in our config from "sh run". This config works.
I'm not familiar with the NetApp in particular, but I can't imagine it is all that different from other networking devices. I'll have to leave that as an exercise for you. ;)
If you still can't get it to work, try something other than the NetApp with the LACP LAG. This might be peculiar to the NetApp.
Another thing you could try is a static LAG. To make a static LAG (LACP is turned off here, though not immediately apparent) try this config on the switch. I believe if you set the load-balance method, you're turning off LACP and making a static LAG. Maybe this explains why LACP isn't working for you?
