centos - iscsiadm "no portals found"

Question

我在 Centos6 服务器上安装了一个 iSCSI 目标，并配置了一个可以在一台客户端机器上找到的目标(网络 192.168.95.x 中的 Ubuntu 1304)。但是，当我再添加一个目标并尝试从另一台机器(同一子网中的 Centos5)连接时，它显示“找不到门户”。以下是设置的打印输出:

同一子网中的 iSCSI 启动器 (192.168.180.x - Centos5)

[root@syslong ~]# iscsiadm -m discovery -t st -p 192.168.180.88
iscsiadm: No portals found

/etc/iscsi/iscsid.conf

    node.startup = automatic
    node.leading_login = Yes
    node.session.auth.authmethod = CHAP
    node.session.auth.username = wilson
    node.session.auth.password = xxxx
    discovery.sendtargets.auth.authmethod = CHAP
    discovery.sendtargets.auth.username = wilson
    discovery.sendtargets.auth.password = xxxx

不同子网中的 iSCSI 启动器 (192.168.95.x - Ubuntu 1304)

wilson@guntank:~$ sudo iscsiadm -m discovery -t st -p 192.168.180.88
[sudo] password for wilson: 
192.168.180.88:3260,1 iqn.2013-08.com.xxx:wy

在 ubuntu 机器上，它只在 iscsi 目标服务器中找到一个目标，但在 iscsi 目标服务器中，可以使用 tgt-admin 命令显示两个目标。是不是我配置有误？

非常感谢!

当我遇到那个问题时，这个命令对我很有用。我希望它适用于遇到此问题的任何人。 (请参阅 tgtadm 的手册页)

 tgtadm --lld iscsi --mode target --op bind --tid 1 --initiator-address ALL
