iSCSI登录失败，错误24 -无法登录到所有门户

Question

我正在尝试设置一个iSCSI目标：

[root@localhost /]# targetcli
targetcli shell version 2.1.fb37

下面是结构(打开新窗口中的图像以查看其大小)：

“发现”似乎运作良好：

[root@linuxbox ~]# iscsiadm -m discovery -t sendtargets -p 10.0.0.60
10.0.0.60:3260,1 iqn.2015-06.world.server:storage.target01

但是，当我试图连接时，我会收到以下授权失败消息：

[root@linuxbox ~]# iscsiadm -m node --targetname "iqn.2015-06.world.server:storage.target01" --portal "10.0.0.60:3260" --login 
Logging in to [iface: default, target: iqn.2015-06.world.server:storage.target01, portal: 10.0.0.60,3260] (multiple)
iscsiadm: Could not login to [iface: default, target: iqn.2015-06.world.server:storage.target01, portal: 10.0.0.60,3260].
iscsiadm: initiator reported error (24 - iSCSI login failed due to authorization failure)
iscsiadm: Could not log into all portals

Answer 1

在客户端机器上，您必须在文件initiatorname中编辑initiatorname.iscsi。其名称是iqn，它被创建为ACL。

$ vi /etc/iscsi/initiatorname.iscsi

InitiatorName=iqn.2015-06.world.server:www.server.world

Answer 2

在我的例子中，启动器的iqn出现了问题-我编辑了文件/etc/iscsi/initiatorname.iscsi并运行了service iscsi restart，但仍然在目标上看到了/etc/messages中的错误：

Dec  2 14:51:05 iscsi-target-vm kernel: iSCSI Initiator Node: iqn.1994-05.com.redhat:47fbcf58e10 is not authorized to access iSCSI target portal group: 1.

12月2日14:51:05 iSCSI -目标-vm内核:iSCSI登录协商失败。

因此，解决方案是在启动器处运行service iscsid restart来重新加载iqn。
