You will probably be able to resize the virtual HDD using a script, however extending the guest OS partition needs to be done using a utility or from within the guest itself and since it is the system partition that needs to be done offline.

I'd recommend you use the GUI to increase the 10 VM's HDD's to the desired size. Then boot each of the VM's to a Vista/Windows7 CD/DVD into recovery mode, selecting the "open command line" option. There you can easily use diskpart to extend the partition using the following commands.

- list vol

- select vol ## (where ## is the number of the volume to extend)

- extend

- exit

Hi,

You can do that using Set-HardDisk cmdlet. Since you want to extent the primary partition you need to pass additional winXP VM where the harddisk will be attached and extended (windows xp does not allow you to exend primary partition). You need ESX host and guest VM user and password as a prerequisite also. Here is the script:

$helperVM = Get-VM "winXPVM"

Get-VM vm1 | Get-Harddisk | Set-HardDisk -CapacityKB 30*1024*1024 -HostUser "hostusername" -HostPassword "hostpassword" -GuestUser "guestUser" -GuestPassword "guestPassword" -HelperVM $helperVM

You can examine the bat script executed in the Windows XP guest located in <PowerCLI InstallDir>\Scripts\GuestDiskExpansion_winXPProGuest.bat (typically C:\Program Files\VMware\Infrastructure\vSphere PowerCLI\Scripts\GuestDiskExpansion_winXPProGuest.bat). It also use diskpart utility to extend the partition.

Please note that this cmdlet is experimental.
