 I think it may be because the corresponding failed drive was lost in the
 array configuration, say:
  # atacontrol status ar0
  ar0: ATA RAID1 subdisks: ad4 status: DEGRADED
 Instead of:
  # atacontrol status ar0
  ar0: ATA RAID1 subdisks: ad4 ad6 status: DEGRADED
                               ^^^
 
 I encoutered a very similar problem recently, and resolved it this way:

 So it not an error in the documentation, but maybe this one may be
 completed.
