Error description
When configuring an HADR database pair for HA via the db2haicu utility, it is possible that the Primary HADR database role fails over to the standby host shortly after db2haicu execution. If this problem occurs and the following two db2diag.log messages are seen on the original standby host, then it is a match for this APAR: 2017-06-25-02.18.03.915829+720 E80421950E389 LEVEL: Info PID : 2695 TID : 48009457543904 PROC : db2gcf INSTANCE: db2inst1 NODE : 000 HOSTNAME: hostB FUNCTION: DB2 UDB, high avail services, sqlhaRemoveFlagRG, probe:673 MESSAGE : Resource flag file has been deleted DATA #1 : String, 49 bytes db2_HADRDB_hostA_Reintegrate_db2inst1_db2inst1 2017-06-25-02.18.03.977507+720 E80422340E393 LEVEL: Info PID : 2695 TID : 48009457543904 PROC : db2gcf INSTANCE: db2inst1 NODE : 000 HOSTNAME: hostB FUNCTION: DB2 UDB, high avail services, sqlhaCreateFlagRG, probe:508 MESSAGE : IBM.Test flag resource has been created DATA #1 : String, 49 bytes db2_HADRDB_hostA_Reintegrate_db2inst1_db2inst1 The root cause for this issue is the 'db2_HADRDB_hostA_Reintegrate_db2inst1_db2inst1' file being left over in /tmp on the standby host.
Local fix
Before you run db2haicu to configure HA, first ensure that there are no leftover flag files in /tmp on either host, i.e. run the "ls /tmp | grep db2_<DBNAME>" command on both hosts and ensure there are no files with this prefix. If there are, they must be deleted.
