由于端口 8145 或 8146 通信故障，SCSQL 资源发现或备份失败

适用于

• SnapCenter 服务器 (SC)
• SnapCenter Plugin for VMware（SCV）
• Microsoft SQL Server 的 SnapCenter 插件 (SCSQL)

问题描述

• 成功安装 SQL 插件后，添加新资源组时无法查看  并从可用性组中进行选择。
• "刷新资源"无法显示集群的 AvailabilityGroup。
• SC 和 SCSQL 插件之间的通信错误，消息见

System.Net.WebException: Unable to connect to the remote server ---> System.Net.Sockets.SocketException: No connection could be made because the target machine actively refused it <IP_address>:8145

• 也可能在 <installation_path>\NetApp\SnapCenter\App_Data\log\SnapManagerWeb_<id>.log 中看到以下资源发现错误：

ERROR SnapManagerWeb_74 PID=[5084] TID=[129] WebException caught while invoking https://Host_FQDN:8145/SMCoreHostManagementService/DiscoverResources

System.Net.WebException: The operation has timed out

• PowerShell（PS）命令 Test-NetConnection <remote_computer_IP> -port 8145 来自 SC 和 SCQL 插件失败
• 在 VMDK 磁盘的情况下，在 SCV vmcontrol.log 中发现 SCV 设备和 SnapCenter 在端口 8146 之间的通信错误：
