re: TD230 - fails to Boot Windows 2008 server os from Raid driveOptions

Hi All,

 I have two Thinkserver TD230 with 4 sas raid 5 hdd configured as one virtual hdd with 2 partitions runninf windows 2008 server os. Server 1 DC and server 2 is member server.

Everythiong was fine until yesterday when a power filre shut the computer down.

Since then the DC server starts  the boot process but does not progress further, whereas server 2 is fine.

The windows repair menu option does not find the raid disks until I add the raid device driver.

I can then see the disks and access them via the command prompt (  from the repair menu).

It seem there is an initial 100mb parition which boots up and is supposed to load the device drivers and then load the main windows OS from the Raid partition.  

It looks like the raid driver fails to load and therefore the OS does not boot.

I have tried the repair option  several times without success.

I am reluctant to restore from a backup image as it is a few days old.

Is there any way to fix this boot problem?

Try the following
Run chkdsk on C: from recovery or bartpe


Boot on BartPE or recovery and copy the raid *.sys file to C:\Windows\System32\Drivers
Be sure to copy the correct version (x86 or x64).

Export the following keys from a working server of the exact same model and import it onto the broken machine..
HKLM\System\CurrentControlSet\Control\CriticalDeviceDatabase

HKLM\System\CurrentControlSet\Services\NameOfTheRaidControllerService

Hi  Greedj,

thanks for the feedback.

How do I export the registry keys to the broken machine?

I assume I need to successfully re-boot the server after copying the drivers to the c:\windows\system32\drivers folder and then import the registry keys specified. Is this correct?

TIA

Run regedit, highlight the key, right click, export.

You will need a recovery cd to import the registry key. I use BartPe or Ultimate Boot CD for Windows.
