在Centos 6上安装Mellanox ConnectX-2 10 PCIe卡

Question

我刚刚在运行PCIe 6.7的服务器上安装了一个MellanoxConnectX-210GbE x8卡。在引导时，dmesg显示mlx4_core驱动程序正在自动加载，但是我没有看到与卡相对应的eth1设备。ifconfig -a只显示eth0，这是我的车载/主板千兆网络接口。

因此，我删除了/etc/udev/rules.d/70-persistent-net.rules并重新启动。它重新创造了70-persistent-net.rules，但只有我的车载/主板千兆网卡，没有进入梅拉诺克斯10 the卡。

/etc/udev/rules.d/70-persistent-net.rules输出

# PCI device 0x10ec:0x8168 (r8169)
SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:30:67:aa:bb:cc", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

好消息是，lspci展示了梅拉诺克斯卡。lspci | grep -i ether输出

dmesg的相关输出：

你知道为什么我的MellanoxConnectX-2不作为eth1设备出现吗？

Answer 1

此卡应在本机工作，不作任何更改。只需删除70-persistent-net.rules/reboot和/或检查dmesg输出即可。

您可能在/etc/sysconfig/network/ifcfg文件中出现了UUID或MAC问题。

如果两者都没有，请从Mellanox或惠普下载驱动程序。
