How to Add a Virtual Hard Disk to a Virtual Machine
Updated: August 14, 2009
Applies To: Virtual Machine Manager 2008, Virtual Machine Manager 2008 R2, Virtual Machine Manager 2008 R2 SP1
You can add a virtual hard disk to an IDE device or a SCSI adapter with the following procedure. By default, any hardware profile includes a built-in IDE drive. You can add and configure up to four virtual SCSI adapters to a virtual machine.
Use this procedure when modifying a hardware profile or configuring hardware profile settings from the New Template Wizard or the New Virtual Machine Wizard.

| In VMM 2008 R2, if a virtual machine is deployed on a host that is using the Hyper-V implementation of the SCSI controller, you can add or remove a virtual hard disk or pass-through disk from the SCSI controller while the virtual machine is running. On all other storage configurations, you must stop the virtual machine before adding or removing a disk. |
