  immediately)
  DR role:                                 UNKNOWN

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  M	Q Appliance users configuring a DR partner for a
  high-availability (HA) queue manager pair.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When configuring a DR partner for an existing HA pair, the
  configuration commands did not correctly check the availability
  of the port which would be used to handle DR work on the HA
  secondary. If the port was not available, the configuration
  would be unsuccessful, but this was not reported to the user.
  Additionally, this failed configuration attempt did not resolve
  itself automatically.
  

Problem conclusion

• The MQ Appliance DR configuration utilities have been updated to
  ensure the availability of the DR on both HA partners before
  proceeding with the configuration.
