Centos7 挂载iscsi网络存储

群晖NAS 创建iscsi跟着提示走就好了,设置chap模式,添加账号密码

centos7 

安装依赖

yum install binutils iscsi-initiator-utils kmod-xfs xfsprogs -y

启动并设置开机启动

service iscsi start
systemctl enable iscsi

登陆节点前需验证

1、开启验证

iscsiadm -m node -T iqn.2000-01.com.synology:DS1618.Target-1.b5f7db4101 -p 10.168.2.195:3260 -o update --name node.session.auth.authmethod --value=CHAP

2、添加用户

iscsiadm -m node -T iqn.2000-01.com.synology:DS1618.Target-1.b5f7db4101 -p 10.168.2.195:3260 -o update --name node.session.auth.username --value=xxx

3、添加密码

iscsiadm -m node -T iqn.2000-01.com.synology:DS1618.Target-1.b5f7db4101 -p 10.168.2.195:3260 -o update --name node.session.auth.password --value='xxxxxx'  # 密码有符号请使用引号

 4、登陆节点

[root@node-02 ~]# iscsiadm -d2 -m node -T iqn.2000-01.com.synology:DS1618.Target-1.b5f7db4101 -p 10.168.2.195:3260 --login
