DB2 FOR LUW / DB2FORLUW / A10 - DB2

In the case where a manual HADR takeover is issued by running 
the "db2 takeover hadr on db <dbname>" command from the standby 
host and it is successful. It is possible that TSA initiates an 
automated HADR takeover immediately after the fact, switching 
the HADR standby and primary back to their original locations 
and leaving them in a disconnected state. 
 
The following db2diag.log message should be seen on the standby 
host at the time that the manual HADR takeover command was 
issued: 
 
2013-09-26-14.17.39.603232-240 E1930E465           LEVEL: Event

Immediately after the above db2diag.log message, the following 
db2diag.log message should be seen: 
 
2013-09-26-14.17.41.260002-240 E2396E435           LEVEL: 
Warning

If this second db2diag.log message is not seen, then this issue 
is being hit. The cause is that the IBM.Test 
ClusterInitiatedMove resource flag was not properly cleaned up 
as part of a prior TSA automated HADR takeover. In order to 
confirm whether or not this flag still exists, verify the output 
of the following commands: 
 
export CT_MANAGEMENT_SCOPE=2 
lsrsrc IBM.Test | grep ClusterInitiatedMove 
 
and 
 
ls /tmp | grep ClusterInitiatedMove 
 
If the ClusterInitiatedMove flag resource or file exists, it 
will need to be manually removed. 
 
In order to remove the flag resource, run the following command 
as root: 
 
rmrsrc -s "Name like '%ClusterInitiatedMove%'" IBM.Test
