In a typical failure one of the drives will be dead and would show up in the utility as offline or unavailable. The remaining working drive would be shown as degraded because the mirror isn't functional. Once you add in the new drive and re-establish the mirror relationship both drives should show as degraded because the volume ID's do not match.
Get your facts first, then you can distort them as you please.
