当存在重复的 NFS IP 地址跨越多个 SVM 时， NDB 无法通过“无法获取存储详细信息”错误进行备份

• NDB 因以下错误无法备份。

Task 'Discovering Resources' failed with error: Unable to discover resources on SCV: Unable to get storage details for datastore <DATASTORE> with managed object reference <DATASTORE>. Storage system(s) may need to be added, also ensure that the associated host is in a connected state.

• 中Unable to get storage details显示的消息“”vmcontrol_<JOB_ID>.log将作为结果SmDiscoverResourcesResponse显示。
