First of all, we strongly recommend that you back up all of your important data before trying any migration, because we don’t know that any company has ever validated RAID migration scenarios. As a result, there is no guarantee of success here whatsoever.
The ideal scenario would be that you only need to attach the drives to the new controller. In most cases it is obviously not going to be that easy ; here are some of the open questions :
Can Windows boot on the target system if the correct storage driver isn’t installed ? You can try selecting a default storage driver under Windows, but our experience has been that this doesn’t work either.
Does the order in which you attach the drives to the storage controller matter ? Some controllers complain, while others don’t.
Is it possible to add the appropriate storage driver ? Yes, it is. You will have to run a Windows XP or Vista repair installation. Go all the way to where you select the installation partition. When Windows ask you if you want to reinstall or repair, choose repair. The system will keep all your installed applications, but you will have to reinstall drivers - including the mass storage driver.
If the migration process fails, will I be able to put the source system back together ? Yes. We did not lose data by hooking up our RAID drives to a new controller. Unless you physically change the RAID setup, the new controller should not touch the disk contents.
Great article, but does anyone know if an ICH7R -> ICH10R migration is possible? I am replacing an ASUS P5WDH Deluxe which died with a new board containing the ICH10R chipset and hope that I can just plug my old drives into the new board without losing the data. I accept I might need to use the XP repair thingy.
My old ICH6R motherboard stopped working and I got a new ICH9R Asus P5K Pro to replace it. When I plugged the old disks I tried to boot winxp and I got to the loading screen but then got a BSOD.
I was already expecting that and tryed to run a repair install. The problem is, even when i correctly load my RAID drivers provided by the mb maker, winxp install doesn't detect the disks. If I set the SATA mode to AHCI in the BIOS winxp can detect them but the repair doesn't allow me to boot windows.
OK - I got my Asus P5Q Deluxe with Intel ICH10R and successfully migrated my 4 drive RAID set from the P5W-DH Deluxe's ICH9R. The only thing is one of the drives shows as off-line (i.e. not part of the RAID set).
Just a note on your Intel chipset migration... I've moved systems from ICH8R to ICH9R (and 10R) controllers without needing to run a Windows Repair installation. All you need to do is ensure that you're running the most up to date chipset drivers BEFORE the migration.
Windows will start up, install the new chipset drivers, and tell you it needs to reboot to complete the driver installation. Reboot again, and you're ready to go.
I've done this with RAID0 and RAID1 arrays, moving from ASUS P5B Deluxe (ICH8R) boards to all of the following: ASUS Maximus Formula (ICH9R), P5K Premium (ICH9R), and P5Q Pro (ICH10R).
I put 2 drives from a nforce3 250 and conected them to a nforce4.
Used a XP-CD with the enforce4 drives embedded.
But i only see 1 partition !?
What am i doing wrong ?
Tryed several stripe sizes.
