Compacting a virtual hard disk can use a large percentage of processor resources. We recommend that you do not perform this operation on a production computer.


To perform this procedure, you must have the appropriate permissions. If you do not have the appropriate permissions, you will either receive an error message or you will not be able to view certain menu items and options described in this procedure. To change your permissions, contact your Virtual Server administrator. For more information, see Securing Virtual Server. You can compact a virtual hard disk only when it is not in use. For more information about compacting a virtual hard disk, see "Compacting dynamically expanding virtual hard disks" in Related Topics. For instructions on opening the Administration Website, see "Open the Administration Website" in Related Topics. Dynamically expanding virtual hard disks are the only type of virtual hard disk you can compact.
