The two ports are connected back-to-back to another mlx4 HCA. I noticed this behavior change since opensm stopped working after rebooting into 3.4-rc1. ibv_devinfo output is as follows: # ibv_devinfo -v hca_id: mlx4_0 transport: InfiniBand (0) fw_ver: 2.9.1000 node_guid: 0002:c903:0005:f34e sys_image_guid: 0002:c903:0005:f351 vendor_id: 0x02c9 vendor_part_id: 26428 hw_ver: 0xA0 board_id: MT_0BB0120003 phys_port_cnt: 2 max_mr_size: 0xffffffffffffffff page_size_cap: 0xfffffe00 max_qp: 131008 max_qp_wr: 16384 device_cap_flags: 0x007c9c76 max_sge: 32 max_sge_rd: 0 max_cq: 65408 max_cqe: 4194303 max_mr: 524272 max_pd: 32764 max_qp_rd_atom: 16 max_ee_rd_atom: 0 max_res_rd_atom: 2096128 max_qp_init_rd_atom: 128 max_ee_init_rd_atom: 0 atomic_cap: ATOMIC_HCA (1) max_ee: 0 max_rdd: 0 max_mw: 0 max_raw_ipv6_qp: 0 max_raw_ethy_qp: 0 max_mcast_grp: 8192 max_mcast_qp_attach: 248 max_total_mcast_qp_attach: 2031616 max_ah: 0 max_fmr: 0 max_srq: 65472 max_srq_wr: 16383 max_srq_sge: 31 max_pkeys: 128 local_ca_ack_delay: 15 port: 1 state: PORT_ACTIVE (4) max_mtu: 4096 (5) active_mtu: 4096 (5) sm_lid: 1 port_lid: 1 port_lmc: 0x00 link_layer: InfiniBand max_msg_sz: 0x40000000 port_cap_flags: 0x0251086a max_vl_num: 4 (3) bad_pkey_cntr: 0x0 qkey_viol_cntr: 0x0 sm_sl: 0 pkey_tbl_len: 128 gid_tbl_len: 128 subnet_timeout: 18 init_type_reply: 0 active_width: 4X (2) active_speed: 10.0 Gbps (4) phys_state: LINK_UP (5) GID[ 0]: fe80:0000:0000:0000:0002:c903:0005:f34f port: 2 state: PORT_INIT (2) max_mtu: 4096 (5) active_mtu: 4096 (5) sm_lid: 0 port_lid: 0 port_lmc: 0x00 link_layer: InfiniBand max_msg_sz: 0x40000000 port_cap_flags: 0x02510868 max_vl_num: 4 (3) bad_pkey_cntr: 0x0 qkey_viol_cntr: 0x0 sm_sl: 0 pkey_tbl_len: 128 gid_tbl_len: 128 subnet_timeout: 0 init_type_reply: 0 active_width: 4X (2) active_speed: 10.0 Gbps (4) phys_state: LINK_UP (5) GID[ 0]: fe80:0000:0000:0000:0002:c903:0005:f350 Bart. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
