VPLEX：分布式设备层次结构是缺失的扩展区
Summary: 本文讨论分布式设备层次结构缺少数据区的问题，以及如何解决数据区缺失的问题。
Symptoms
查看分布式设备的组件层次结构时，设备分支缺少扩展区。VPlexcli:/> show-use-hierarchy distributed-storage/distributed-devices/device_CLARiiON1234_LUN_00030_1

Cause
Resolution
此显示问题的解决方法是使用内部固件命令在数据区顶部插入新的 R0 设备。此过程不会造成任何影响，但只能由技术支持人员完成。
永久修复：
由于这是一个表面问题，目前没有永久的修复方法。
