Turn the computer off.
Unplug its power-cord.
Connect its power-cord.
Turn the computer on, and enter "BIOS SETUP".
Check the "Boot Options", to ensure that your RAID-array is listed as one (preferably the first) of the bootable devices.
1. Is this a new (clean) install? If so, have you installed the drivers for the RAID controller BEFORE you install the os? Most of the time Windows will ask for this as the os check your sysem. (You will see at the bottom of the screen "if you have a 3rd party controller and need to install drivers, do so now" or something to this effect.
2. If you already have an os on this system, (Server 2008) you may need to check the the HCL for SBS 2011 to make sure you hardware is correct for the install.
use this guide, this is fo the embedded sata raid controller that comes standar with the ml150 g5.
Enabling SATA RAID functionality in the BIOS Setup Utility:
1.Boot the server, and then press F10 to enter the ROM-Based Setup Utility (RBSU).
2.Go to the advanced tab.
3.Enter the IDE configuration or hard disk configuration.
4.Change the ATA/IDE configuration to enhanced or SATA controller 2 enhanced (if not available then use enabled mode).
5.Configure SATA as RAID or configure controller 1 as RAID.
6.F10 to save and exit.
7.Reboot the server.
8.During post f8 will now show up for the embedded SATA set up.
•Creating the RAID volume.
1.Enter the embedded SATA setup by pressing f8 during post.
2.Enter the array configuration utility.
3.Enter create array.
4.Create the raid volume as desired.
5.Save and exit.
Did you experience a power event? Go to BIOS (F2), and make sure that RAID is Enabled. If RAID got turned off (power event, BIOS reset), then it will give you that message. If RAID is already enabled, then you may need to repair your operating system. If something else happened (drive failures, drives removed, etc.), then the array may be completely gone. Call Data Recovery services if it is critical you retreive the data.
You need to go into setup view you drive array sounds like you may have one bad drive or the raid array has dropped by moving drives around hope this is what is wrong then re initialize the drive array you need more help email me at mje.bend at live dot com
If the only drive you changed was the drive that failed and all the others are in the correct sequence, then that's a good thing.
The next question is, did you have this system setup in a RAID Array and if so, what RAID configuration were you using (RAID 0,1,5, etc.)? Some RAID configurations allow you to replace a failed drive and not lose data, but I will need to know more about how you set the system up in order to help you more.
Are you able to get into the array configuration and make sure the logical drive is still intact? If the logical drive is gone, then your partition may be lost. If you are able to recover the logical drive in your array (which you should be able to if the RAID5 striping was stable) then you should be able to recover your data. You can get into the array configuration during the boot up sequence.
Try all means to get a smartstart CD.
Normally new version will be able to use on older hardware , but no guarantees.
I have always found it easier to use smartstart CD auto mode.
You can also do the install and then run ntssd to update all the drivers etc., but I don't recommend it for novices. Use the auto mode , it takes longer but safely and surely.
You don't say whether or not your os is on the RAID 5 partition. Assuming that it is (for performance reasons, this is not recommended) then you should check to see if you have the option of configuring a separate raid configuration on your raid card (e.g. do you have a card with more then one RAID channel?) If this is so, I would create a separate RAID 1 array and install the OS just on that. Then you can mount the RAID 5 array with your data intact. Once you're up and running, you can remove the old OS partition, as it's no longer needed.
