IT17623: MQ APPLIANCE: QM-BEFORE-RESYNC LOGICAL VOLUME LEFTOVER WHEN FAILING OVER AND DELETING QUEUE MANAGER ON OTHER APPLIANCE

APAR status

• Closed as program error.

Error description

• Two appliances are configured in a high availability group with
  a third appliance configured for disaster recovery. While the
  primary HA appliance is rebooting the disaster recovery
  configuration is removed and the queue manager is deleted on the
  secondary HA appliance. The queue manager is successfully
  deleted on the secondary HA appliance but the disaster recovery
  resources, including logical volumes, are not correctly deleted
  on the primary HA appliance once it has restarted.
  

Local fix

• When deleting a queue manager that has been configured for both
  high availability and disaster recovery users should ensure that
  both appliances in the high availability group are available.
  

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of the IBM MQ Appliance who have established two
  appliances in a high availability configuration plus a third
  appliance for disaster recovery.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  A logic error in the routines to handle disaster recovery meant
  that not all resources were removed correctly.
  

Problem conclusion

• Disaster recovery processing has been updated to correctly clean
  up resources for a queue manager that has been deleted on the
  other appliance in a high availability group.
