Error description
Two appliances are configured in an high availability group with a third appliance configured for disaster recovery. The queue manager's disaster recovery role is changed while connectivity for the HA primary and secondary interfaces is broken. The disaster recovery state of the queue manager becomes inconsistent on the two HA appliances and this state is not automatically resolved when connectivity is restored.
Local fix
Users who have configured appliances for both high availability and disaster recovery should avoid changing the disaster recovery role when connectivity between the HA appliances is broken.
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: The HA appliances stored the disaster recovery role in both the HA subsystem and in an separate local data store. These two copies of the state information were not consistently updated when connectivity between the HA appliances was interrupted.
Problem conclusion
The use of a separate local data store to track the disaster recovery role has been removed so there is now one copy of the state information managed by the HA subsystem. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.6 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
