This Knowledge Base article provides information about attempting to perform a Windows Server 2008 R2 Install Clone installation when the Primary server uses a SCSI Raid bus and the Secondary/Tertiary server uses a SAS Raid bus.
Attempting to perform an Install Clone installation on a Windows Server 2008 R2 server that has a SCSI Raid bus and the Secondary/Tertiary server has a SAS Raid bus results in a failure of the Operating System to properly start.
When Windows Server 2008 R2 starts, to accelerate the startup process, it disables services that are not used. As such, since the backup was taken on a SCSI Raid bus, the SAS Raid services are not started.
Prior to taking the backup of the Primary (SCSI Raid bus) server, edit the registry to enable the SAS Raid services.
To enable the SAS Raid services:
- Navigate to Start > Run, type Regedit.exe, and click OK.
Navigate to the following registry keys:
- Change the value of the registry keys from "3" to "0".
- Save the changes.
- Take the backup of the Primary (SCSI Raid bus) server.
- Proceed with the remainder of the installation process.
