DPC：DD SSO 连接因连接或套接字超时而失败

检查 DPC 与 DD 之间的基本网络连接：

使用以下命令检查是否启用了从 DPC 到 DD 的出站端口 3009：

• 使用 SSH 以管理员身份登录到 DPC CLI，然后 su - 以 root 用户身份登录，然后运行以下命令：
• 取代 <DD_FQDN_OR_IP> 替换为 DD 服务器的 FQDN 和 <SYSADMIN_PASSWORD> 替换为 sysadmin 密码。

curl -k -X POST https://<DD_FQDN_OR_IP>:3009/rest/v1.0/auth -H "Content-Type: application/json"  -d '{"username":"sysadmin","password":"<SYSADMIN_PASSWORD>"}'

如果此连接正常工作并且端口 3009 可以访问，则会收到如下所示的输出：

{"details": "success", "code": 0, "link": [{"rel": "related", "href": "/rest/v1.0/system"}]}

如果返回的“details”未显示“success”，则这是网络连接问题，需要打开网络开机自检。  

检查是否启用了从 DD 到 DPC 的出站端口 443。要执行此作，请以用户 sysadmin 身份使用 SSH 登录 DD CLI。然后，进入 SE 模式：

system show serialno                     #To get the serialno of the system, which will be used to enter SE mode
                                         #When prompting for security officer authorization, enter SO username&password.
                                         #When prompting for system password, enter system serialno.

然后运行以下命令，将 DD FQDN> 替换为 < DPC 服务器的 FQDN：

se telnet <DPC FQDN> 443

如果连接正常，您会看到一行”Connected to <DPC FQDN>.“

如果 elg.log 显示握手错误运行以下命令以检查密码。

openssl s_client -tls1_2 -connect <DD_HOSTNAME>:3009 -cipher ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES128-SHA256:AES256-GCM-SHA384:AES256-SHA256:AES128-SHA256:AES128-SHA:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-SHA256 2>/dev/null >dd_communication.txt

取代 <DD_HOSTNAME> 在上述命令中使用 DD 服务器的 FQDN。

检查“dd_communication.txt”文件，它应类似于以下输出。

CONNECTED(00000003)

如果“Shared Requested Signature Algorithms”行为空，则这是密码问题，我们必须与 DD 团队联系，以添加 DPC 使用的密码才能正常工作。

检查 短信。信息 日志位于 /ddr/var/log/debug 目录中的目录。

如果 SMS.信息 日志显示“无法获取 SSO 端点”，跟随 Data Domain 拒绝与 Data Protection Central 的单点登录连接，必须从 Data Domain 检查此问题 ，以解决此问题。 

如有其他问题，请联系戴尔支持。
