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

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:

在ubuntu计算机中,它仅在iscsi目标服务器中找到一个目标,但是在iscsi目标服务器中,可以使用tgt-admin命令同时显示两个目标。我有什么配置不正确的东西吗?

非常感谢!

最佳答案

这是一个ACL问题。

在iSCSI-Target中运行以下命令:

tgtadm --lld iscsi --op bind --mode target --tid 1 -I ALL

然后运行以下命令:

iscsiadm -m discoverydb -t st --p 192.168.1.5
