Transplanting RAID Array

[Gu4rdi4n]

Hey all, I am hoping someone can give me some insight on this...

As far as I know, when one has RAID1 (running through hardware RAID controller - not software based), the array gets created with a unique ID, which will allow the system to detect when a new drive has been inserted etc.

Is it possible, though, to take this array (2 SATA drives in RAID1 config) and transplant it as is to a new system? Without reinstalling the OS etc?

I understand the implications in doing this, I am just more curious about if I am just too narrow minded on the topic or whatever. Because I have tried something similar and ended up losing data off both disks, does anyone have a suggestion for how it can be done properly? Alternatively, a decent reason for why it shouldn't be done?

I am litterally about to slam my laptop closed on my head with this one - so any insight would be appreciated!

You have the following options, from my POV:
1. Transplant the RAID controller with the disks. The controller knows about the configuration, and thus it should work.
2. Remove one disk, and make it the master on a new RAID configuration. Add another disk then to sync from it.
3. Create new array, and restore the data from the old array to the new.

Backups are strongly recommended before you even try to do any of the above.

Thanks for the reply, Nod

I have been reading this morning about the second method you posted. It sounds more viable than I thought before.

Option one is a no-go, since it is a desktop motherboard and the RAID controller is onboard. Ideal situation would be if it were a server system with a proper RAID controller card, but of course, we live in an imperfect world.

Keep in mind that Windows might BSOD due to device driver incompatibilities with the new motherboard should you transplant the HDD's.

I would rather create a new RAID (with new hard drives), then sync overnight via the network.

Keep in mind that Windows might BSOD.

I am partially hoping it does, as this would prove my point

I will update with the info when I actually get to the system.

Thanks, everyone, for the info

Damagement not understanding the risks?

Heh, do keep us updated

Depending on the motherboard that you have it may not be hardware RAID. If you are running XP/Win2003 you may be able to simply transfer them to the new system; it depends on the chipset on the board. The second option may also not work, depending on the motherboard (assuming it is fakeRAID). Best would be to clone the current disks, and reimage onto the new RAID array....
