Replacing failed drive in RAID 1 array

I have to replace a RAID 1 hardware mirrored drive in a 2003 Server.  The server is 6 years old.  It has a Adaptec AIC-7902 based Utra320 SCSI / MegaRAID SCSI 320-1 RAID Controller.  I have purchased an identical drive to the surviving drive in the server.  I was wondering if anyone has experience replacing a drive in this configuration and would give me some direction.

I can't say I have used that particular Adaptec drive but I have done a few Raid 1 mirror drive replacements.

If it is hot-swappable (I don't think it is, but if you know different ... it is your server), just remove the failed drive and slap in another.  If it is not, then remove the drive when powered off, insert the other and power on.  The aim is to acknowledge any errors and the RAID BIOS will rebuild the array automatically.

If there is Adaptec management software installed in the OS you will be able to watch the progress from the Disk Management mmc console.

I would say take a backup first so you can be confident.
Use the Adaptec management tool that comes with the card and REMOVE the failed drive, effectively breaking the mirror and putting the array in single drive mode.
Shut the server down, replace the drive, bring it back up and ADD the new drive as a mirror using the array manager that prompts you during the bootup process. This will initiate a rebuild.
