检测硬件RDMA卡是否存在
1、检查网卡是否安装成功: # lspci | grep Mellanox 83:00.0 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx] 83:00.1 Ethernet controller: Mellanox Technologies MT27710 Family [ConnectX-4 Lx] 2、查看系统网卡: # ifconfig eth0 Link encap:Ethernet HWaddr 18:66:DA:98:A3:02 inet addr:10.20.15.23 Bcast:10.20.15.127 Mask:255.255.255.128 ...... eth3 Link encap:Ethernet HWaddr 18:66:DA:98:A3:08 ...... lo Link encap:Local Loopback ...... tunl0 Link encap:IPIP Tunnel HWaddr ...... 3、查看系统里所有的网卡和工作状态: # ip a 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 inet 127.0.0.1/8 scope host lo inet6 ::1/128 scope host valid_lft forever preferred_lft forever 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP qlen 1000 link/ether 18:66:da:98:a3:02 brd ff:ff:ff:ff:ff:ff inet 10.20.15.23/25 brd 10.20.15.127 scope global eth0 inet6 fe80::1a66:daff:fe98:a302/64 scope link valid_lft forever preferred_lft forever 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 18:66:da:98:a3:04 brd ff:ff:ff:ff:ff:ff 4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether 18:66:da:98:a3:06 brd ff:ff:ff:ff:ff:ff 5: eth3: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc mq state DOWN qlen 1000 link/ether 18:66:da:98:a3:08 brd ff:ff:ff:ff:ff:ff 6: eth4: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether ec:0d:9a:d2:fd:68 brd ff:ff:ff:ff:ff:ff 7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN qlen 1000 link/ether ec:0d:9a:d2:fd:69 brd ff:ff:ff:ff:ff:ff 8: tunl0: <NOARP,UP,LOWER_UP> mtu 1480 qdisc noqueue state UNKNOWN link/ipip 0.0.0.0 brd 0.0.0.0
当驱动没有安装成功的时候,检测RDMA网卡是否存在 lspci |grep mon
