Symptoms

查看分散式設備的元件層次結構時，設備支線缺少擴展數據塊。

Cause

在極少數情況下，由於磁碟區上有範圍遷移，可能會發生此問題。遷移完成後，元件層次結構中的擴展數據塊頂部缺少 R0 （RAID 0）設備。

Resolution

元件層次結構中缺少 R0 設備是外觀問題。將裝置保留在此狀態，不會對 VPLEX 作業產生任何明顯影響。但是，如果需要解決此外觀問題，請向 VPLEX 支援開立服務要求，並提及本文。

此顯示問題的解決方案是使用內部韌體命令，在範圍上方插入新的 R0 裝置。此程序不會造成任何影響，但只能由技術支援人員完成。

永久修正：
由於這是外觀問題，因此目前沒有永久修正。
