APAR status

• Closed as program error.

Error description

• In a pureScale environment it is possible to drop a CF in the
  middle of Rolling Upgrade (that is, Rolling Upgrade has started
  but not completed and members are at different fix pack levels).
  Once that occurs a CF cannot be added back as the following
  SQLCODE is returned:
  
  SQL1648N  The SQL statement or command cannot be processed
  because of the state of a DB2 member in a DB2 pureScale
  environment. Member = "129". Reason code = "10".  SQLSTATE=57061
  
  Further, rolling upgrade cannot be cancelled as two CF's are
  required:
  
     Minimum 2 CFs are required to perform online fixpack updates
      DBI20135E  The online fix pack update has halted because the
  secondary CF is not in PEER state.
  
  Thus during Rolling Upgrade the dropping of a CF is now blocked.
  

Local fix

• Complete the rolling upgrade before dropping a CF
