LINUX 下进行MD3220 I 安装

教程发布:风哥 教程分类:ITPUX技术网 更新日期:2022-02-12 浏览学习:39

1. 测试后总结,
a) 1. 设置服务器IP
b) 安装ISCSI INITIATOR
c) 启动ISCSI服务,让ISCSI服务自动启动
d) 安装device-mapper
e) 建立多链路文件,有多少块网卡就建立多少个文件,并修改文件和网卡匹配
f) ISCSI查找链路iscsiadm –m discovery –t st –p 192.168.130.101:3260
g) ISCSI logon 注册服务器iscsiadm –m node -l
h) 安装MSDM(先mount,然后cd /mnt/Server/iscsi******)
i) MAP 服务器
j) 查看SESSION
k) 修改多链路文件使生效
l) 查看路径
m) 修改多链路文件,给别名,使LUN名称固定
n) 格式化LUN
o)
2. 设置IP 略
a) Eth0:192.168.128.19
b) Eth1:192.168.130.23
c) Eth2:192.168.131.23
