IT38347: Queue Managers will not run on the preferred node after MQ Appliance reloads.

APAR status

• Closed as program error.

Error description

• A clean shutdown of the cluster process did not occur after the
  HA primary MQ appliance reloaded.  As a result, some of the
  resource attributes were left behind.  When the cluster
  processes restarted, they prevented some of
  the queue managers to return back to its preferred node.
  
  The status for the queue manager will show the following:
  
  QM(QUEUE_MANAGER)                        Status(Running
  elsewhere)
  HA role:                                 Secondary
  HA status:                               Normal
  HA control:                              Enabled
  HA preferred location:                   This appliance
  DR role:                                 Primary
  DR replication type:                     Asynchronous
  

Local fix

• Contact IBM MQ Support to receive a service console key to
  remove the files that were left behind.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  All MQ Appliance users using it for High Availablity(HA) and
  Disaster Recovery(DR).
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  When MQ Appliance reloads, if a clean HA shutdown does not
  happen then it leaves behind some  HA transitory files. These
  files were not removed when the cluster restarted, and as a
  result queue manager was unable to move back to the original
  node where it was running.
  

Problem conclusion

• The code has been modified to ensure the transitory files used
  for the cluster management are removed when the cluster
  restarts.
