Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of the IBM MQ Appliance who configure primary and
  secondary DR queue managers may be affected by this issue.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  The crtdrprimary command accepts a RecoveryIP for the -i option.
   If a valid hostname is given instead of an IP address then this
  is accepted and stored as a field inside a configuration file.
   A task which is called during strmqm and dltmqm later read the
  field inside the configuration file and expected to find a
  resolved IP address.  When a hostname was found the task ended
  abnormally and this caused the strmqm and dltmqm commands to
  fail.
  

Problem conclusion

• The MQ Appliance firmware has been modified so that a valid
  hostname will be resolved to an IP address and this address is
  then stored in the configuration file.  An invalid hostname will
  result in a configuration error and it will not be stored in the
  configuration file.
