PowerProtect Data Manager — vCenter 发现失败，而虚拟机备份仍正常工作

此 vCenter 的虚拟机备份仍正常工作，但发现不起作用，这导致客户无法添加新虚拟机。

从 GUI：
messageID=ADS0001,message=Virtual machine asset discovery on the vCenter xxx. was unsuccessful.,detailedDescription=Virtual machine asset discovery cannot be completed because of unrecoverable error conditions.,responseAction=Check the connection between PowerProtect Data Manager and vCenter. Verify that the provided credentials are valid. Start a manual discovery to discover all virtual machine assets, or wait for PowerProtect Data Manager to perform the next scheduled discovery. If the issue persists, contact Dell Customer

但我们已经确认不存在连接和凭据问题
我们可以运行以下命令进行验证。

1. ./ppcp vcenter show permission
2. ./ppcp vcenter test 

在 vmdm-discovery 日志中，我们可以看到以下键错误 401 Unauthorized：

我们发现 VMware vAPI 端点服务未运行，请联系 VMware 管理员以启用 vAPI 端点服务。
service-control --start vmware-vapi-endpoint

在 PPDM 上运行以下两个命令以重新启动服务，从而重新建立与 VMware 的连接。
