NetWorker：NMC 服务和可访问性问题（一般故障处理指南）

如果 NetWorker Management Console （NMC） 服务器安装在 NetWorker 服务器或独立主机上，则可以遵循此知识库文章。在继续操作之前，请确认环境详细信息。 

初始步骤

• NMC 是否安装在 NetWorker 服务器或独立主机上？
• 收集环境详细信息：NetWorker：识别 NetWorker 软件版本的方法
• NMC 服务是否正在运行：
  • Linux： systemctl status gst

• Windows：在 services.msc 中，EMC GST 数据库、EMC GST 服务和 EMC GST Web 服务应正在运行。

 

• NMC 客户端是否可以访问 NMC 服务器？：
  • Windows PowerShell：

tnc nmc-server-hostname -port 9000
tnc nmc-server-hostname -port 5432

问题和症状

• 无论使用何种用户帐户，NetWorker Management Console （NMC） 登录都会失败;错误：

There is a problem contacting the server, nmc_server_name. Please verify that the server is running.

• gstd.raw包含指示服务或数据库问题的消息：

• NetWorker 服务器服务已启动，可以使用 nsrwatch 命令在 NetWorker 服务器上、从 NetWorker Web 用户界面 （NWUI）（如果已安装）或从具有网络和 NetWorker 服务器访问权限的另一个 NMC 服务器观察服务器功能。

基于操作系统返回功能的选项：

Linux

Recoverpsm

重新配置

重新安装

Windows

服务

1.在 NMC 服务器上，打开 services.msc
2。查看每个 EMC GST 服务。
3.确认服务所有者为默认值：

Recoverpsm

重新安装
