系统环境 centos 8.1
服务器环境 戴尔R740服务器 2张12GB sas HBA卡
存储环境 DELL ME4084存储
阵列环境 5个RAID6 每个raid6由16个8TB硬盘组成
硬盘环境 84个8TB硬盘
系统安装 忽略
存储配置
1.本地网卡配置为 10.0.0.22
2. 通过管理口 10.0.0.2登录
3. 第一次登录需要设置用户名和密码 这里设置为admin1 密码[email protected]
4. 首选设置raid,这里设置为5个raid6
5. 然后建立映射
6.登录centos系统配置
7.查看磁盘状态

8.未发现磁盘,看看fba卡是是否识别

9.识别到FBA卡和存储,重启centos系统.
10.重启后查看磁盘
fdisk -l

11.存储磁盘已经被发现,而且有很多呢.
12.查看多路径软件是否安装
lsmod |grep dm_multipath
13.安装多路径软件
yum install device-mapper device-mapper-multipath
14.运行多路径软件
multipath –ll
Jul 22 22:15:08 | /etc/multipath.conf does not exist, blacklisting all devices.
Jul 22 22:15:08 | You can run "/sbin/mpathconf --enable" to create
Jul 22 22:15:08 | /etc/multipath.conf. See man mpathconf(8) for more details
Jul 22 22:15:08 | DM multipath kernel driver not loaded
15.安装提示运行
[[email protected] ~]# /sbin/mpathconf --enable
17.启动服务并查看
[[email protected] ~]# /bin/systemctl start multipathd.service
[[email protected] ~]# multipath -ll

18.已经全部正常识别,接下来就是分区和挂载了,
19,和原来的不同,就是不需要那么麻烦些uuid之类的,自己编辑了,multipath软件会自动识别.方便了不少.
