Hi everyone! I have two Mellanox 2-port NIC’s (MT27700) in an HPE DL360 server. One NIC is 25 Gb Ethernet, the other is 100 Gb InfiniBand. The two Ethernet ports are teamed (LACP), and work great, until I setup IB.
I am using CentOS 7.6 (minimal install). After I install libmlx5, libibverbs, and rdma-core, and start the RDMA service, my ssh connection drops and I can’t reconnect.
I see this in /var/log/messages (eno5 and 0000:5d:00.0 refer to the Ethernet NIC port):
May 8 17:23:57 ipapphpc01-1 teamd_team0: eno5: Port seems to be loopbacked to the same team device.
May 8 17:23:57 ipapphpc01-1 kernel: mlx5_core 0000:5d:00.0: modify lag map port 1:2 port 2:2
May 8 17:24:26 ipapphpc01-1 kernel: mlx5_core 0000:5d:00.0: modify lag map port 1:1 port 2:2
What is this message referring to? What am I missing?
