Hi tdubb.  You can use the Set-Harddisk command.  When you provide credentials for the guest OS it will use VIX to run a batch script to extend the disk on the guest.

http://www.vmware.com/support/developer/PowerCLI/PowerCLI41/html/Set-HardDisk.html


Here is the example provided in the previous link.

Set-HardDisk -HardDisk $harddisk -CapacityKB $extendedCapacity -HostCredential $hostCred -GuestCredential $guestCred

What OS is the guest running.  Some Operating Systems either do not have a extend script, or are not supported by VIX.



If you want to have a look at the scripts go here on any server with PowerCLI installed.

Hi,

IIRC for the WIndows Server 2003 and below it requires restart or not possible. Can you please clarify this if its true ?

on th book page 219 it said that it requires Helper VM, what is that ?

/* Any kind of comment or input would be greatly appreciated */

which OS supports the the VIX script? I am trying to resize that on a win7 machine. I was able to change the disk size but the guest os did not resize it

Get-Harddisk -vm name | where {$_.name -eq "Hard disk 2"}| Set-Harddisk -CapacityKB $value -HostCredential $HostCred -GuestCredential $GuestCred -Confirm:$false

To resize the OS partition you'll need to use the HelperVM parameter on the Set-Harddisk cmdlet.
