AUTH CONFIG GROUP
=================
mutual_password=AnotherPassword
-------------------------------
The mutual_password auth parameter.
mutual_userid=OutgoingUser
--------------------------
The mutual_userid auth parameter.
password=SomePassword
---------------------
The password auth parameter.
userid=IncomingUser
-------------------
The userid auth parameter.Initiator端配置
1.配置iscsid.conf 文件
$ sudo vim /etc/iscsi/iscsid.conf
# 去掉以下几行注释，并根据Target端配置设置用户名和密码
node.session.auth.authmethod = CHAP
node.session.auth.username = IncomingUser
node.session.auth.password = SomePassword
node.session.auth.username_in = OutgoingUser
node.session.auth.password_in = AnotherPassword2.发现目标
