Unfortunately looks like the engineer in question had rebuilt the drive we were looking for, and the two sets he thought he had were actually from two completely different machines. I am now going to provide some super high intensity training in the area of "labelling".
Thanks for all the feedback, it was still a valuable learning exercise.
There's been much frustration and banging of heads on desks about this, however as embarrassing as it is I'd like to call upon the collective wisdom here to see if there is a simple answer to this problem. I won't go in to detail about how we've ended up in this absolutely stupid situation but suffice to say that everyone is well aware how stupid it is! Unfortunately, i've been tasked with trying to make the best of it.
Ok the current situation is:
- We have FOUR hard drives that are identical.
- They are in RAID 0 pairs.
- Each pair came out of a different machine.
- We DO know which drives belong together, so we have two pairs.
The numpty that took them out neglected to write two important things on the drives:
- Which pair came from which machine.
- Within the pair, which one is disk 0 and which is disk 1.
Following some further unfortunate happenings today we are now in a situation where, to make the best of a pretty nasty situation, I need to get one of those pairs back in to service as it transpires they might be the latest and greatest copy of some important data.
The question therefore is simple:
Is there an easy way to determine, out of each pair, which is 0 and which is 1 - so that I can put each pair in to a machine and see if it is the right one? I have the machine they came out of, and they both came out of identical machines so I expect they will both work ok, however my biggest concern is getting the disks in the right order.
Am I missing something here and might get myself in deeper water?
Other than taking a big stick to the persons involved in this, what are the best opinions and advice snippets that you can offer me to help get those drives resurrected in their original machines?
Within those drives, the server is running Windows Server 2003, and is a Dell 1950. I have other dells including 2950's that I could put the drive(s) in as slaves if there is software that can help identify them. My biggest concern is ensuring no further data loss of course!
