APAR status

• Closed as program error.

Error description

• Target server can crash under the following conditions.
  
  Source server has container pool(s).
  Target server has container pool(s) with nextstgpool configured
  Protect stgpool is run on source server
  Replicate node is run on the source server.
  Target server container pool(s) has no free space and thus
  nextstgpool has to be used.
  
  During "replicate node", the target server can crash when trying
  to write the data to the storage pool
  defined by the nextstgpool option for the container pool.
