cannot get device settings:no such device

ifconfig看不到eth0,eth1.
用ethtool ethX检查了下说是：
[tex=code]
cannot get device settings:no such device
cannot get wake-on-lan settings:no such device
cannot get messag level:no such device
cannot get link status:no such device[/tex]
ifup eth0提示找不到设备

重启网络失败。

dmesg，message有类似日志

可能是网卡驱动的问题
安装网卡驱动

安装完成之后仍然不行，对比正常机器，发现/lib/firmware 下文件缺失
[tex=code][root@n128048 ~]# ls /lib/firmware/|grep bnx2
bnx2
bnx2x
bnx2x-e1-5.2.13.0.fw
bnx2x-e1h-5.2.13.0.fw
[root@n128048 ~]#[/tex]


把正常机器上的拷过去就ok了。idrac下先制作iso，然后挂载即可。
