The subordinate was attempting to join the group, but did not receive a response from the cluster master.
If the master was unavailable for a short period of time, no action is required, and the join attempt will succeed. If this error message continues, check the log files for other error messages. Make sure the master is running correctly. Consult the "Maintenance and Problem Determination Guide" for suggestions for assessing system health. Contact IBM Technical Support.
