由于自己对ESXi的命令不熟悉，同时粗心大意，误删除了ESXi操作系统的分区，操作过程如下：
获取磁盘设备信息：
[root@localhost:~] fdisk -l
[root@localhost:~] fdisk -l

ESXi操作系统安装在硬盘： /dev/disks/t10.ATA_____WDC_WD5000AADS2D00S9B0________________________WD2DWCAV9D135907上，
我执行的操作命令：partedUtil delete /dev/disks/t10.ATA_____WDC_WD5000AADS2D00S9B0________________________WD2DWCAV9D135907 1
导致硬盘的1号分区丢失。
[root@localhost:~] fdisk -l

唉，结果就悲剧了………………
在系统不重启的情况下，系统还能正常运行，我把重要的数据拷贝了出来，还好只有两台虚拟机。系统重启后直接无法启动。
