This morning a drive failed on our database server. The drive array (3 disks) is setup in a RAID 5 configuration.

While we wait for a drive replacement we are preparing for a recovery strategy. Users are continuing to work on the system, albeit very slowly (don't know why??).

How does one install the new drive - will the data for this drive automatically be rebuilt from the parity or is there another process we should follow?

Edit: This is a hardware RAID controller. (Thanks for the answers so far, appreciated)
