APAR status
Closed as program error.
Error description
When the links between HA Primary and HA Secondary are down(when a HA connection is lost), problems with UUID causes problems to find the DR Partitioning on either the DR Primary or DR Secondary. The APAR also addresses a problem of running the commands "/sbin/drbdadm" and "/bin/dd" under mqsudo to generate new UUID, which we don't have permission to run under mqsudo at present and get below errors.

Local fix
Problem summary
**************************************************************** USERS AFFECTED: MQ Appliance users with HA-DR. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A logic error when generating a UUID associated with the DR partition internally on the MQ Appliances meant that the partition could not be mounted correctly if the HA links were unavailable when this mount was attempted.
Problem conclusion
The MQ Appliance logic which mounts the DR partition has been updated to handle the UUID correctly if the HA links are down. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD 9.1.3 v9.1 LTS 9.1.0.3 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 ---------------------------------------------------------------
