APAR status

• Closed as program error.

Error description

• A path error caused the affected LSS00 to LSS00 Metro Mirror ppr
  c pair got suspended. However, TPC-R did not suspend other pairs
   in the same MM session. The logs indicated there is an
  IndexOutOfBoundsException at that time which contributed to this
   not handling the suspension of other pairs correctly.
  

Local fix

Problem summary

• A suspend event could be initially received on
  a "Defined" session that has copysets added. The suspend event
  
  from the LSS would be caught and set a flag on the suspend
  marker. Since the session is in a defined state it does not do
  anything with the event. However this will cause a mismatch with
  the suspend
  marker and the event listener. On subsequent events this
  mismatch will cause some of the LSS to
  LSS pairings to not receive the suspend event from the hardware.
  

Problem conclusion

• Sessions in the defined state now have the marker initialized
  prior to the start command. This will ensure that the
  suspend marker and event listener are in synch.
