1、首先查看多路径软件是否安装：rpm -qa |grep device-mapper
2、如未安装，请安装(在安装盘的Packages中)：device-mapper-multipathdevice-mapper或运行yum install -y device-mapper device-mapper-multipath
3、如已安装，请执行如下命令：mpathconf --enbale在/etc下生成配置文件：multipath.conf
4、启动多路径：service multipathd start或systemctl start mutipath.service
5、查看启动状态：service multipathd status或systemctl status mutipath.service
6、至此，Multipath安装配置完成。
7、以下命令可以参考：查看WWN地址：cat /sys/class/fc_host/host*/port_name扫盘命令：echo "- - -" > /sys/class/scsi_host/host0/scan 或重启服务器查看磁盘：fdisk -lmultipath -ll
