由于反向 IP 查找配置问题，PowerProtect Data Manager 文件系统代理注册失败

新安装

后，PowerProtect Data Manager 文件系统代理注册失败在 PowerProtect Data Manager UI>Application Agents Registration>Status 中，在接受证书后显示 Failed。  

在 C:\Program Files\DPSAPPS\AgentService\logs\OpAgentSvc-******.log，它显示以下内容 PPDM IpCheck validation failed 为 /greetings call。

2. Alternatively, 'Auto Allow List' can be enabled on PowerProtect Data Manager server.
3. Ensure there is no connectivity issue from PowerProtect Data Manager server to agent system.
4. Restart the agent service and try again.

PowerProtect Data Manager 文件系统代理注册失败的根本原因是缺少反向 IP 查找配置。在该节点上运行 nslookup 以验证 PowerProtect Data Manager 的名称解析。它适用于 PowerProtect Data Manager 主机名，但不适用于反向 IP 查找。 

PowerProtect Data Manager 文件系统用户指南中记录了“必须配置名称解析和反向 IP 查找” 

解决方法是在 DNS 服务器上配置 PowerProtect Data Manager 的反向 IP 查找。如果此时无法访问 DNS 服务器，请临时修改客户端的 hosts 文件。之后，UI 中的 注册状态应自动更改为 等待批准。如果没有，请手动重新启动客户端上的 PowerProtect 代理程序服务。
