Question

好的我有一个实验室设置，我有一个Freenas服务器iscsi设置与Chap设置发现和目标的相互分裂。

以下是要求：实施CHAP安全性用于发现的单向CHAP 目标的双向（相互）CHAP

我可以使用两台esxi服务器，Windows 7，Windows 2003,2008和2012进行成功连接和发现

Centos可以看到发现列表，但在尝试连接时：

 iscsiadm --mode node --targetname iqn.2015.lab.com:centos --portal 192.168.1.60:3260 --login

终端输出：

no records found

这是我的iscsid.conf，我把评论留在Chap部分，但是把它删除了，因为它太大了：

    iscsid.startup = /etc/rc.d/init.d/iscsid force-start
    node.startup = automatic
    node.leading_login = No

    # *************
    # CHAP Settings
    # *************

    # To enable CHAP authentication set node.session.auth.authmethod
    # to CHAP. The default is None.
    node.session.auth.authmethod = CHAP

    # To set a CHAP username and password for initiator
    # authentication by the target(s), uncomment the following lines:
    #node.session.auth.username = group7
    #node.session.auth.password = passwordpassword

    # To set a CHAP username and password for target(s)
    # authentication by the initiator, uncomment the following lines:
    node.session.auth.username_in = group7
    node.session.auth.password_in = passwordpassword

    # To enable CHAP authentication for a discovery session to the target
    # set discovery.sendtargets.auth.authmethod to CHAP. The default is None.
    discovery.sendtargets.auth.authmethod = CHAP

    # To set a discovery session CHAP username and password for the initiator
    # authentication by the target(s), uncomment the following lines:
    discovery.sendtargets.auth.username = group7
    discovery.sendtargets.auth.password = passwordpassword

    # To set a discovery session CHAP username and password for target(s)
    # authentication by the initiator, uncomment the following lines:
    #discovery.sendtargets.auth.username_in = group7
    #discovery.sendtargets.auth.password_in = passwordpassword


    node.session.timeo.replacement_timeout = 120
    node.conn[0].timeo.login_timeout = 15
    node.conn[0].timeo.logout_timeout = 15
    node.conn[0].timeo.noop_out_interval = 5
    node.conn[0].timeo.noop_out_timeout = 5
    node.session.err_timeo.abort_timeout = 15
    node.session.err_timeo.lu_reset_timeout = 30
    node.session.err_timeo.tgt_reset_timeout = 30
    node.session.initial_login_retry_max = 8
    node.session.cmds_max = 128
    node.session.queue_depth = 32
    node.session.xmit_thread_priority = -20
    node.session.iscsi.InitialR2T = No
    node.session.iscsi.ImmediateData = Yes
    node.session.iscsi.FirstBurstLength = 262144
    node.session.iscsi.MaxBurstLength = 16776192
    node.conn[0].iscsi.MaxRecvDataSegmentLength = 262144
    node.conn[0].iscsi.MaxXmitDataSegmentLength = 0
    node.conn[0].iscsi.HeaderDigest = None
    node.session.nr_sessions = 1
    node.session.iscsi.FastAbort = Yes

感谢任何帮助。谢谢。

您需要用于会话设置的双向CHAP，但在配置文件中，您已注释掉了定义从启动器到目标的登录的行：

# To set a CHAP username and password for initiator
# authentication by the target(s), uncomment the following lines:
#node.session.auth.username = group7
#node.session.auth.password = passwordpassword

Iscsi Chap用于发现，互为目标将无法连接。
