UCS C Series Standalone with Shared LOM in port channel

[rjucio]

I've got a couple of Cisco C series hosts running with the Shared LOM in active/standby mode. Is this supported when the NICs backing the Shared LOM are running in a port channel? It seems the CIMC is not contactable unless I place the host in maintenance mode in vSphere (removing all workloads from the host). Should the Shared LOM be in active/active mode under a port channel? Or is this not at all supported?

If your upstream switch itself is configured in a LACP type port-channel, then I don't think the CIMC redundancy is designed for that(active-active) type of config.  If you are doing generic teaming based on 'originating port-ID' then that may work.

You may also want to try setting the CIMC network redundancy to active/standby, which may allow your upstream switch to be in real port-channel/LACP, and esxi host config to have ip-hash.

Can you confirm what kind of switch port-channel is configured, and what ESXi teaming algorithm is configured?

The CIMC NC-SI connection for active-active uses Adaptive Load Balancing/ALB with 2 different macs for each nic for the CIMC.

I'm confirming what type of port-channel we have, but it should be Etherchannel as this is the only supported teaming config for a vSphere Standard Switch using route based on IP hash.
