Hi list, I am afraid I am stuck with a very stupid problem, and I am at my wit's ends. I am deploying a set a blades loaded with ConnectX-3 VPI adapters. The blades run under RHEL 6.3 and the connectors are driven using the MLNX_OFED 1.5.3.3 stack. When the ports are configured in IB (default), the physical state of the ports is POLLING, which is expected since the adapters are connected with Ethernet wires and switches: $ ibstat CA 'mlx4_0' CA type: MT4099 Number of ports: 2 Firmware version: 2.10.2322 Hardware version: 0 Node GUID: 0x0002c90300f31160 System image GUID: 0x0002c90300f31163 Port 1: State: Down Physical state: Polling Rate: 40 Base lid: 0 LMC: 0 SM lid: 0 Capability mask: 0x02514868 Port GUID: 0x0002c90300f31161 Link layer: InfiniBand Port 2: State: Down Physical state: Polling Rate: 40 Base lid: 0 LMC: 0 SM lid: 0 Capability mask: 0x02514868 Port GUID: 0x0002c90300f31162 Link layer: InfiniBand But when I enable the ports as ETH, the physical state shows up as DISABLED: $ ibstat CA 'mlx4_0' CA type: MT4099 Number of ports: 2 Firmware version: 2.10.2322 Hardware version: 0 Node GUID: 0x0002c90300f31160 System image GUID: 0x0002c90300f31163 Port 1: State: Down Physical state: Disabled Rate: 40 Base lid: 0 LMC: 0 SM lid: 0 Capability mask: 0x00010000 Port GUID: 0x0202c9fffef31160 Link layer: Ethernet Port 2: State: Down Physical state: Disabled Rate: 40 Base lid: 0 LMC: 0 SM lid: 0 Capability mask: 0x00010000 Port GUID: 0x0202c9fffef31161 Link layer: Ethernet Besides, ibportstate fails opening the port in ETH mode: $ ibportstate -C mlx4_0 -L 0 -P 1 q Finally, if that helps, when set in auto mode, the port configuration stick with IB. I went through any possible user guide without help. Any clue about what I am doing wrong?
