    Migrate a single drive to RAID 0 (two drives)

    andrewbadge

      Hi,

       

      I have a Z68 motherboard (Gigabyte GA-Z68M-D2H) with Intel RAID/Rapid Storage.
      I currently have a single SATA drive with a single volume/partition (running Windows Home Server 2011 aka 2008 R2).

       

      I would like to migrate the current config to a 2 drive RAID 0 or 3 Drive RAID 5.

       

      Questions:

       

      1. Can you migrate (preserve the existing volume) without having to reinstall. The documentation sort of says yes but the screenshot shows "All data will be lost" warning.

       

      2. If the answer is yes to above: I'd assume i'd install the Intel RAID drivers first, then go into the BIOS to enable RAID and migrate to the RAID volume.

      That way the drivers for the RAID are already present once the server reboots?

       

      Thanks for your time.

          Hello!

           

           

          It is possible to migrate to a RAID 0 or RAID 5 volume with the chipset that comes in that motherboard.  When the software says “All data will be lost” it will preserve the information that is in one of the Hard Drives (you will be able to choose which Hard Drive you want to preserve) and the information in the other Hard Drive will be deleted.  Most of the time the system disk is the one that is going to be preserved since it is the one that has the Operating System.  Check the following links, and you will be able to know how to setup this migration.  Please read all the links before you change anything in your system.

          The Operating System you are using on this system is not supported under Intel Desktop chipsets so; we cannot guarantee everything will work fine under Windows Server.  Please check with the manufacturer of the motherboard the supported operating systems.

           

          Thanks!

            I have tried almost every guide available on the internet and couldn't find anything that worked until I stumbled upon a little gem over at Microsoft of all places! The solution is actually quite simple, if not a little time consuming.

             

            1) Go into your registry and enable the RAID storage drivers. (Microsoft) This is actually where most people run into a brick wall. Windows has to load the RAID drivers during the start-up sequence in order to properly use a RAID array.

            1. Exit all Windows-based programs.
            2. Click Start, type regedit in the Start Search box, and then press ENTER.
            3. If you receive the User Account Control dialog box, click Continue.
            4. Locate and then click the following registry subkey:

              HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV

            5. In the pane on the right side, right-click Start in the Name column, and then click Modify.
            6. In the Value data box, type 0, and then click OK.
            7. On the File menu, click Exit to close Registry Editor.

            2) Make a backup. Safety is paramount, after all.

            3) Restart your computer, enter the BIOS, and change the storage option to RAID.

            4) Depending on your RAID controller, you might have the option to choose which drive will be the "host" drive. If, like me, your controller says all data will be erased you will need to ensure that you have a good backup just in case things go awry. In any case, once the array is created, Windows should attempt to load without immediately going to the BSOD (Blue Screen of Death) since we enabled RAID storage drivers in step 1.

            5) If you're using two new drives, you can simply migrate/clone your system to the new array with whatever software you prefer (I like EaseUS). If you slapped a new drive together with your old drive to create a new array you'll have to cross your fingers that the controller detects the data and rebuilds during the restart or just restore your backup to the newly created RAID. Once again, since the OS was configured with RAID storage drivers activated it will start up with no issues and you've lost no data in the process!

             

            The key to this entire process is step 1!
