我刚刚在运行CentOS 6.7的服务器上安装了一个Mellanox ConnectX-2 10gbe PCIe x8卡。 在启动时,dmesg显示mlx4_core驱动程序被自动加载,但是我看不到对应于该卡的eth1设备。 ifconfig -a只显示eth0 ,这是我的板载/主板千兆networking接口。
所以,我删除了/etc/udev/rules.d/70-persistent-net.rules并重新启动。 它重新创build了70-persistent-net.rules但只有我的板载/主板千兆网卡,Mellanox 10gbe卡没有条目。
输出/etc/udev/rules.d/70-persistent-net.rules
# 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显示了Mellanox卡。 输出lspci | grep -i ether lspci | grep -i ether

dmesg相关输出:

任何想法为什么我的Mellanox ConnectX-2没有显示为eth1设备?
这张卡应该原生地工作,没有任何改变。 只要删除您的70-persistent-net.rules /重新启动和/或检查dmesg输出。
您可能在/ etc / sysconfig / network-scripts / ifcfg-ethX文件中遇到UUID或MAC问题。
如果两者都不是这样,请从Mellanox或HP下载驱动程序。

我想出了解决办法。 我所要做的只是input两个命令来激活CentOS 6中的网卡:
sudo modprobe mlx4_core sudo modprobe mlx4_en
现在我有ifconfig -a eth1 ,可以configuration它(IP地址,networking掩码等)
为了使其在重新启动时永久保存,我添加了一个新文件/etc/sysconfig/modules/mellanox.modules ,并将其权限(chmod)设置为755,作为所有者/组:
#!/bin/sh /sbin/modprobe mlx4_core /sbin/modprobe mlx4_en
这会在启动/ etc / sysconfig / network-scripts中指定的eth0 / eth1configuration之前,在启动时自动加载内置于CentOS的Mellanox内核模块
现在它就像任何其他networking接口一样工作。
