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Linux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。

1、开启ESXi的TSM-SSH服务

2、使用远程工具连接至ESXi

3、获取已安装的磁盘设备信息

   # esxcfg-scsidevs -l     查看主机识别的磁盘设备

4、其中t10.ATA_____PLEXTOR_PX2D128M5S_______________________P02349103954________就是安装过Linux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

5、删除分区：1 2 是get出来的分区编号

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

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

6、删除完成后再到vSphere Client里面重新添加磁盘即可

7、esxcfg-scsidevs的用法：

[root@localhost:~] esxcfg-scsidevs
esxcfg-scsidevs <options>
Print the mappings between vmhba names and /dev names
-l|--list                  List all Logical Devices known on this
                           system with device information.
-c|--compact-list           List all Logical Devices each on a
                           single line, with limited information.
-u|--uids                  List all Device Unique Identifiers with their primary name.
-d|--device                Used to filter the --list, --compact-list
                           and uids commands to limit output to a
                           specific device.
-m|--vmfs                  Print mappings for VMFS volumes to their
                           Service Console partitions and vmhba names.
-f|--vfat                  Print mappings for VFAT volumes to their
                           Service Console partitions and vmhba names.
-a|--hbas                  Print HBA devices with identifying information
-A|--hba-device-list       Print a mapping between HBAs and the devices it
                           provides paths to.
-o|--offline-cos-dev       Offline the COS device corresponding to this vmkernel
                           device.
-n|--online-cos-dev        Bring online the COS device corresponding to this vmkernel
                           device.
-h|--help                  Show this message.

8、partedUtil工具的用法：

[root@localhost:~] partedUtil -h
