  ABENDIOL008
  
  During PPRC summary unit check recovery, guests accessing the
  affected devices which don't support the summary unit check are
  presented with state change interrupts.  However, this code does
  not currently check if the VDEV which would receive the
  interrupt is in the process of being detached.  This results in
  an IOL008 if the VDEV lock is obtained for presenting the state
  change interrupt while the detach is in process.
  

Problem conclusion

• The code which presents state change interrupts to guests was
  updated to check the VDEVNOTO flag which indicates that a given
  VDEV is in the process of being detached.  If the indicator is
  set, the state change interrupt will not be presented for that
  device.
