ESXi下磁盘分区删除步骤详解

如果在vSphere Client里面添加已经安装过操作系统的磁盘（如安装过Windows系统的磁盘），那是无法再直接添加驱动器的，需要SSH登录到ESXi的控制台进行操作。

获取磁盘设备信息：

# esxcfg-scsidevs -l

其中t10.ATA_____PLEXTOR_PX2D128M5S_______________________P02349103954________就是安装过Windows系统的硬盘，获取它的分区信息：

~ # partedUtil get /vmfs/devices/disks/t10.ATA_____PLEXTOR_PX2D128M5S___________
____________P02349103954________
15566 255 63 250069680
1 2048 718847 7 128
2 718848 250069646 7 0
删除分区：

~ # partedUtil delete /vmfs/devices/disks/t10.ATA_____PLEXTOR_PX2D128M5S________
_______________P02349103954________ 1
~ # partedUtil delete /vmfs/devices/disks/t10.ATA_____PLEXTOR_PX2D128M5S________
_______________P02349103954________ 2

删除完成后再到vSphere Client里面重新添加磁盘即可。

附esxcfg-scsidevs的用法：

~ # esxcfg-scsidevs -h
esxcfg-scsidevs
