Note: The system volume must be an IDE controller. In addition, up to two
more volumes can be attached to an IDE controller. If you are
protecting more than three volumes on the source, you will need to
install the Hyper-V Integration Components to acquire a SCSI device.
See your Hyper-V documentation for more information.
If your source is Windows 2003 or Windows 2008 with no service
packs and you have selected a SCSI controller, you will need to
manually install the Hyper-V Integration Components after failover to
attach these volumes to the replica virtual machine.
