NWUI 解决方案用于管理 NetWorker 数据区。导航面板用于选择“Protection>Groups”,详细信息窗格生成”Failed to get the list of groups. Unable to parse 'disk_uuid' string: '50301dd2-9032-1b04-eca2-c943c61fd55d.'“ VMware 保护组配置了使用标记选择受保护虚拟机 (VM) 的规则,并且引用的虚拟机具有磁盘排除项。

NWUI 组无法加载,并显示“无法解析disk_uuid字符串”

Cause

对于排除的 .vmdk 磁盘,VMware 保护组具有虚拟机 null 条目。空 .vmdk 磁盘条目导致 RESTAPI 在检索保护组信息时失败。VMware 保护组资源中的空条目显示为退格和引号 (\“\”)。以下是 VMware 保护组中 null 条目的示例:
{\"moref-id\":\"vm-1024536\",\"uuid\":\"50301dd2-9032-1b04-eca2-c943c61fd55d\",\"type\":\"VMDisk\",\"disks\":[\"\",\"6000C292-524d-1baa-f10b-5e780833a1ed\",\"6000C29c-75b5-ad1f-27d3-602b6d5da260\"]}

null 条目的原因未知。

Resolution

使用 NetWorker 管理程序 (nsradmin) 从 NetWorker 资源数据库 (nsrdb) 中删除空的 .vmdk 磁盘条目。 
 

  1. 执行服务器保护备份作业并确保获得引导数据库备份:
mminfo -B
  1. 在 NetWorker 服务器上创建 nsrdb 目录的拷贝。
  • Linux: /nsr/res/nsrdb
  • Windows: C:\Program Files\EMC NetWorker\nsr\res\nsrdb

3.从命令行或 Linux shell 打开 nsradmin 命令行实用程序,并通过输入以下命令访问可视模式: visual。这将加载一个交互式命令行实用程序,您可以通过它浏览和修改 NetWorker 资源:
 

nsradmin > visual mode > NSR Protection Group > Select the "NSR Protection Group" > Edit > delete the NULL Disk entry in the "vproxy group exclude items" > save > Exit


之前:

{\"moref-id\":\"vm-1024536\",\"uuid\":\"50301dd2-9032-1b04-eca2-c943c61fd55d\",\"type\":\"VMDisk\",\"disks\":[\"\",\"6000C292-524d-1baa-f10b-5e780833a1ed\",\"6000C29c-75b5-ad1f-27d3-602b6d5da260\"]}

之后:

{\"moref-id\":\"vm-1024536\",\"uuid\":\"50301dd2-9032-1b04-eca2-c943c61fd55d\",\"type\":\"VMDisk\",\"disks\":[\"6000C292-524d-1baa-f10b-5e780833a1ed\",\"6000C29c-75b5-ad1f-27d3-602b6d5da260\"]}

如果发现任何问题,您可以恢复到应用更改之前创建的 nsrdb 拷贝。
