APAR status

• Closed as program error.

Error description

• Configured cluster level resources are dropped when a
  dynamic cluster scales to zero members and back up again.
  

Local fix

• Do not allow clusters to scale to zero members

  ****************************************************************
  When an existing dynamic cluster with configured cluster level
  resources scales to zero members, the prior defined cluster
  level resources are lost when the dynamic cluster scales back to
  one or more members.
  

Problem conclusion

• The dynamic cluster administration code was altered to preserve
  any existing cluster level resources when a dynamic cluster
  scales down to zero members and then back up to one or more
  members.
  
  The fix for this APAR is currently targeted for inclusion in fix
  packs 9.0.0.11 and 8.5.5.16.  Please refer to the Recommended
