Replace DELL 2950III RAID HD

Hi all,


We have some 3 dell 2950III, running RAID 1+0 with 8 hard drives.

1 of them is failing as per my ESX SERVER monitoring, as we have some hard drives laying here,  around, the question is:

If i put a hard drive with data on it, what the raid controller will do?  will it format the disk and add it to the raid 1+0? will it isolate the drive?

Please share your experiences!

Thanks

Actually, it does make a difference .. if the older HDD has metadata from a Dell controller with metadata from a similar controller, but OLDER firmware revision, then it is possible the controller will not talk to the drive, or do unpredictable things.

But that is a corner case, I just want to be complete on the issue.   Otherwise, just don't worry about it.   You do, however, want to use enterprise class, and not a cheap desktop class drive.  The firmware isn't designed for that firmware.  A desktop drive guarantees data loss in a long list of failure scenarios.

Actually is the same disk brand size and speed. just out of another dell 2950 III with the same raid controller perc 6, but as i am out of the country to format the disk myself, i think about asking someone to go ahead and remove the failied one and put this disk in place.
Ok.  Then you are good to go.  Just install it and let it rebuild.
well, i will give it a shot.
