LBFO Issue on 2012 R2 (Network Steve Forum)

LBFO Issue on 2012 R2

Hi,

I'm having an issue with a new LBFO team on 2012 R2 on 2 servers. I've successfully created 2 other teams on each server, but for some reason the 3rd team will not work.

Servers are HP DL580 Gen8. NICs are multiple HP Ethernet 1Gb 4-port 331T. Driver version 17.0.0.3.

Servers are in process of being built as a new Hyper-V failover cluster.

The 3 LBFO teams:

VM (NICs VM 1 and VM 2) - this is going to a different switch (Cisco, 3750 if I recall) that is not configured for teaming (as far as I know), so team is configured as Switch Independent with Dynamic. This appears to be working fine.

HV_CSV (NICs HV_CSV 1 and HV_CSV 2) - connected to Cisco x. The switch is configured with EtherChannel. Team is configured as LACP with Dynamic. This appears to be working fine.

HV_LM (NICs HV_LM 1 and HV_LM 2) - connected to different physical Cisco switches, but part of same stack (I think) as HV_CSV switch. The switch is configured with EtherChannel. Team is configured as LACP with Dynamic. This is not working. Only one adapter shows as up under teaming, with the other showing as Faulted due to LACP negotiation. I can't ping the other server with the same config on the IP address assigned to this NIC (same issue in other direction), suggesting it's not actually working

Things I've tried (in addition to our network team checking the switch config):

- Disabling the 'working' team member, disabling and re-enabling the faulted team member - the faulted team member starts to work. Enabling the previously working team member - this team member now shows faulted due to LACP negotiation

- Switching cables from CSV 1 and CSV 2 into LM 1 and LM 2 - CSV team continues to work, LM continues to have the same issue with one team member not working. This test seems to point to something on the server rather than an issue with the switch config

- Deleting the CSV team and only having the LM team (and VM) - same issue

To me, this seems like it's pointing to an issue on the LM 1 and/or LM 2 adapters but I don't know what it could be. I have a few things to try today (trying some of the other available network adapters, swapping out the network cables to the switch for crossover cable and changing to switch independent) but I'm out of ideas after that.

Has anyone seen a similar issue to this before or have any suggestions what else to check please?

PowerShell output for the teams:

Hi Leo,

Thanks for your reply.

First update, I resolved the pinging issue on server 2. There was an issue with VLAN on one of the ports on the switch.

Still had the issue with the LACP teams though.

We'd checked we were on latest HP drivers as part of the build. These cards use a Broadcom chipset, so just checked their site and they did have a later driver (17.2.0.0 for the 1657).

I've just put that on the servers and bounced them. It has resolved the issue!

I've opened a ticket with HP to report the bug.

Thanks for your help!

HP confirmed they've seen this before and they are looking into it. Their advice is what I've already done - use native drivers (Broadcom) rather than the HP ones. Mentioned something about the Broadcom drivers supposedly being better for virtual switches too, but no details.
