More Information

Symptoms

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.

Cause

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.

Resolution

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:

  1. Navigate to Start > Run, type Regedit.exe, and click OK.
  2. Navigate to the following registry keys:

    HKLM\SYSTEM\CurrentControlSet\services\LSI_SAS
    HKLM\SYSTEM\CurrentControlSet\services\LSI_SAS2
  3. Change the value of the registry keys from "3" to "0".
  4. Save the changes.
  5. Take the backup of the Primary (SCSI Raid bus) server.
  6. Proceed with the remainder of the installation process.
