Raid 5 Failure

I have a Compaq ML 370 server with a Smart Array 221 Comtroller configured as Raid 5 with 6 18.2 GB drives.

One of the drives failed, and is now being issued an ID of 13. The new drive gets an ID of 5. No matter what I do, the array still sees a drive with ID 13 as having failed. I don’t know where it is getting this ID number as all the drives have ID from 0 to 5

I have been told the only way to solve this is to re-do the whole server, but this is not an option at the moment.
