  ****************************************************************
  GDPS/Active-Active Controller does not initialize correctly
  when the local Multi-Site Workload Lifeline Advisor role does
  not correspond to the default role of the GDPS/Active-Active
  Controller which is initializing.
  This can lead to numerous problems including:
  - Failed Scripts
  - Incorrect displays on Web Application panel VPCWAWO1,VPCWAWOM
  -  Routing actions initiated by Web Application buttons may not
     complete successfully
  - Change Master operations may not complete successfully
  

Problem conclusion

• GDPS/Active-Active Controller initialization has been modified
  to ensure that when a Controller initializes, its role (Primary
  or Backup) will correspond to the role of its local Multi-Site
  Workload Lifeline Advisor (Primary or Secondary).
  Subsequent Change Master operations, and handling of AQS0164W
  and AQS0189W messages will execute cleanly and leave the
  GDPS/Active-Active Controllers + Multi-Site Workload Lifeline
  Advisors in the correct states.

  ===========================================================
  
  Message GEO1178A has been modified as follows:
  
  GEO1178A PRIMARY LLA IS DOWN. TAKE CORRECTIVE ACTION.
  
  Explanation: GDPS/Active-Active has issued a switch prompt for
  a Primary Lifeline Advisor failure based on message AQS0164W or
  or AQS0189W issued by a secondary lifeline advisor.
  This prompt is issued when:
    - The primary lifeline advisor stops, and is restarted
      as secondary (which is the recommended procedure for
      restarting an advisor)
    - The secondary lifeline advisor can no longer contact a
      Primary Lifeline advisor.
  Action: Take corrective action to activate a Primary Lifeline
  Advisor. Respond to the outstanding WTOR with one of the
  options listed in message GEO1172E.
    - Reply 'YES' to initiate lifeline advisor takeover on the
      Backup GDPS/Active-Active controller system
    -  Reply 'NO' To SUPPRESS any action.
  
    Note: GDPS/Active-Active performs the Lifeline Advisor
    Takeover on the current GDPS/Active-Active Backup Controller.
    This is in order to preserve the Multi-site Workload Lifeline
    Lifeline routing state data, which is lost if a Takeover
    is performed on the former primary Lifeline advisor.
