    sys/dev/disk/ata     ata-raid.c 
  Log:
  ata-raid associates raw ata disk devices to record the raid setup and checks
  for the existance of an associated si_disk structure to determine whether
  the associations remain valid.  In DragonFly the abstracted 'disk' layer
  is now above the raw drive device rather then integrated with the raw drive
  device and thus the raw device does not have an si_disk association.  Change
  the conditionals to simply check for the existance of the device.
  
  The prior check was resulting in drives being marked damaged in the raid
  when they weren't, making the raid unusable and requiring a complete rebuild.
  Though it is possible to rebuild and regenerate the labels (e.g. using
  scan_ffs) without losing data, it is painfull to have to do it.
