Failed disk on Raid 1

Usually when I have a failing Hard drive in a raid configuration I just replace the disk and it will automatically issues. I'm a little over cautious with this situational.

 Setup: Raid 1 with perc6/ i controller 2008 x64.

 I initially reseated the disk and let it rebuild but it failed again after the rebuild. Ran diagnostic and indicated bad hard drive.

I called Dell to send me a new disk. Dell wanted me to update firmware before they would send new disk.  I updated the raid controller firmware and rebooted. Now in the bios raid configuration it shows a missing hard drive and in the open managed it show the disk as foreign.

They have another disk on the way but I'm a little hesitant to stick the new disk in until I understand what will happen.
When I replace the failed drive the controller should recognize it and start a rebuild or will I have more steps before it joins the new disk to the virtual disk under my Raid 1.
I'm afraid it will break my raid and I will lose all Data (this is where my OS resides). Anyone have any knowledge of this situation and what is the best procedure to join this new disk back to my raid 1 without any data loss.

It is probably a simple procedure but just being cautious.

    Accepted Solution

    Yes, as long as the original disk remains active the new disk should build as you described with no extra steps.

    No porblem, also if you are still concerned I would just make a phone call to Dell before replacing the drive, and they will walk you through it.
