iSCSI 登录失败，错误为 24 - 无法登录到所有门户

我正在尝试设置 iSCSI 目标：

发现似乎工作正常：

[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，当我尝试连接时，我收到此授权失败消息：

[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

答案1

就我而言，启动器的 iqn 存在问题 - 我编辑了文件/etc/iscsi/initiatorname.iscsi并运行， 但仍然在目标service iscsi restart 中看到错误：/etc/messages

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-target-vm 内核：iSCSI 登录协商失败。`

所以解决方案是service iscsid restart在启动器上运行以重新加载 iqn。

答案2

在客户端计算机上，您必须编辑initiatorname文件中的 initiatorname.iscsi.名称是作为 ACL 创建的 iqn。

$ vi /etc/iscsi/initiatorname.iscsi

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