由於自己對ESXi的命令不熟悉，同時粗心大意，誤刪除了ESXi操作系統的分區，操作過程如下：
獲取磁盤設備信息：

ESXi操作系統安裝在硬盤： /dev/disks/t10.ATA_____WDC_WD5000AADS2D00S9B0________________________WD2DWCAV9D135907上，
我執行的操作命令：partedUtil delete /dev/disks/t10.ATA_____WDC_WD5000AADS2D00S9B0________________________WD2DWCAV9D135907 1
導致硬盤的1號分區丟失。

唉，結果就悲劇了………………
在系統不重啟的情況下，系統還能正常運行，我把重要的數據拷貝了出來，還好只有兩台虛擬機。系統重啟后直接無法啟動。
