Symptoms:

   When performing any recovery operation from a Hyper-V environment to a vCenter environment, VM's running Windows Server 2008/2008R2 with IDE disks on the Hyper-V side will fail to boot correctly.    

Cause:

   When VM's with IDE disks are recovered to a vCenter environment, the bus type is changed from IDE to Scsi. This requires that the LSI_SAS driver in Windows be activated at boot time, which is not normally the case.    

Solution:

To resolve this, it will be necessary to change the start type for the LSI_SAS driver in Windows on the protected (Hyper-V) site.

• Open Regedit, navigate to HKLM\System\CurrentControlSet\services\LSI_SAS
• Change the item named 'Start' to a value of 0x0
• After adjusting the 'start' item, perform force sync on the relevant VPG
