iSCSI客户端登陆认证失败

下面为转载内容,当时客户端连不上iscsi服务器,查了好多文章都是说认证没匹配,但是我的认证是匹配的,最后找到这个才发现我修改完客户端配置之后原来的缓存没删,导致一直登陆不了。

 

[root@server ~]# iscsiadm -m node -T iqn.2017-12.com.example.storage1 -p 172.25.254.156 -l

Logging in to [iface: default, target: iqn.2017-12.com.example.storage1, portal: 172.25.254.156,3260] (multiple)

iscsiadm: Could not login to [iface: default, target: iqn.2017-12.com.example.storage1, portal: 172.25.254.10,3260].

iscsiadm: initiator reported error (24 - iSCSI login failed due to authorization failure)

iscsiadm: Could not log into all portals

解决方法:

1)检查钥匙是否正确

vim /etc/iscsi/initiatorname.iscsi

若是修改了文件,需要重启服务

[root@server ~]# systemctl restart iscsid

[root@server ~]# systemctl restart iscsi

2)删除所有文件,重新发现

[root@server ~]# yum install tree

[root@server ~]# tree /var/lib/iscsi/
