iSCSI 登錄失敗，出現錯誤 24 - 無法登錄所有門戶

我正在嘗試設置 iSCSI 目標：

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

這是結構（在新視窗中打開圖像以查看全尺寸）：

發現似乎工作正常：

[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，當我嘗試連接時，我收到以下授權失敗消息：

[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

在客戶端電腦上，您必須編輯initiatorname文件中的 initiatorname.iscsi. 該名稱是作為 ACL 創建的 iqn。

$ vi /etc/iscsi/initiatorname.iscsi

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

就我而言，啟動器的 iqn 存在問題 - 我編輯了文件/etc/iscsi/initiatorname.iscsi並執行 service iscsi restart ，但仍然/etc/messages在目標上看到錯誤：

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 核心：iSCSI 登錄協商失敗。`

所以解決方案是在啟動器處執行service iscsid restart以重新載入 iqn。
