Dell服务器网卡驱动升级[CentOS 5.5 X86_64和RHEL 5.6 X86_64]

系统：CentOS 5.5 X86_64、RHEL 5.6 X86_64

硬件：Dell R610、R710、R720

通过升级系统自带网卡驱动程序到最新版本，可以解决当网卡流量过大时，出现掉包、断网现象。

升级步骤：

1.查看当前网卡类型

# /sbin/lspci |grep Ethernet

02:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

02:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

03:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

03:00.1 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 Gigabit Ethernet (rev 20)

 

2.查看网卡驱动模块

# cat /etc/modprobe.conf|grep eth

alias eth0 bnx2    #-->网卡模块为bnx2

alias eth1 bnx2

alias eth2 bnx2

alias eth3 bnx2

 

# ethtool -i em1

driver: e1000e

version: 2.3.2-NAPI

firmware-version: 0.13-4

bus-info: 0000:00:19.0

 

3.查看网卡驱动当前版本

# modinfo bnx2

4.下载最新网卡驱动程序

到以下链接，根据查询到的网卡型号下载最新的驱动程序：

http://zh-cn.broadcom.com/support/ethernet_nic/downloaddrivers.php

 

5.驱动程序安装

unzip linux-7.2.20.zip

cd Server/Linux/Driver/

rpm -ivh netxtreme2-7.2.20-1.src.rpm

cd /usr/src/redhat/SPECS/

rpmbuild -bb netxtreme2.spec

cd ../RPMS/x86_64/

rpm -ivh netxtreme2-7.2.20-1.x86_64.rpm

 

6.加载最新驱动模块

#vi change.sh

rmmod bnx2

modprobe bnx2

 

执行脚本：

sh change.sh

 

7.查看最新驱动版本

#modinfo bnx2
