 I wish I had seen this issue earlier so I could have sent a suggestion 
 (in all fairness this should have been a post to an email list, like 
 freebsd-scsi, freebsd-stable, or even freebsd-questions.
 
 If you have a degraded stripe-only RAID, then you're basically SOL. That 
 aside.. if you didn't use a straight RAID-0, you could have readded the 
 new drive as a hot spare like so:
 
  	mfiutil add <drive-number> <volume>
 
 and the controller would have added the drive to your RAID.
 
 That's all you need to do when rebuilding a degraded, recoverable RAID via 
 mfiutil.
 
 HTH,
