IT36594: Appliance QMgrs configured for HADR fail to be migrated from 9.1to 9.2 if the HA interfaces were down during the upgrade

APAR status

• Closed as program error.

Error description

• When there is an HA/DR configuration in the MQ Appliances and
  an upgrade to 9.2 is being performed, the 'sethagrp -u' command
  must be run to migrate the DR resources. However, if there is a
  connection problem between the HA interfaces on the MQ
  Appliances
  during the upgrade then the sethagrp -u (-f) command fails to
  migrate
  the queue manager. The command reports that the High
  availability
  configuration is already migrated and the queue manager fails to
  start on the upgraded node.
  
  The status of the queue manager shows as 'Resource failed'

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users using HA and DR configuration on MQAppliance and migrating
  from version 9.1 to 9.2.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  If the HA connections were down between the HA appliances while
  the first node was being upgraded then the 'Migration Pending'
  flags was not set. When sethagrp command was run with -u option
  to migrate the queue manager to the 9.2 version, it reported the
  queue manager is already migrated. The command failed to migrate
  the queue manager even when run with -f option.
  

Problem conclusion

• The code has been modified to ensure that the queue manager
  migration succeeds if sethagrp -u -f command is run even if the
  'Migration Pending' flag is not set.
