redhat7.3多路径配置

多路径配置主要步骤如下:

1. 查看是否安装多路径软件包

rpm -qa|grep device-mapper

[rootfjlocalhost 勒 rpm -qa |grep devica-fliApper device-aapper -1.62.135 * i * el 7.x86_64 drvir?-mpp«'r iftultipath libs 3 .0-99.^17 . vS6_64 device-upper pe nslstent - data -0.6,3-1. tfl7. xfi5_64 device-sapper -multipath ■ & + 4 占-99 ・ el.7.xe6_64 devlce^HApper -llbS-1,82335 -1 -fl!7.xS6_64 device-Mappc r event ■ 1.02 J 35 1.e!7< device-«pper -event -llbs-1. G2.135 * 1 »e!7. x86_6^

2. 如果系统没有安装多路径软件包，使用 yum 安装

yum in stall -y device-mapper device-mapper-multipath

3. 生成多路径配置文件

mpathconf --enable

说明：生成配置文件是/etc/multipath.conf

4. 启动多路径服务

service multipathd start 或 systemctl start multipathd.service

5. 查看多路径服务状态

service multipathd status 或 systemctl status multipathd.service

6. 创建多路径开机自启动服务

systemctl enable multipathd.service

7. 查看HBA 的WWN
