IBM Security Guardium: Warning: Central-manager of this managed-unit is unreachable (ip=CM) v11p300

Question & Answer


Why do I see a message Warning: Central-manager of this managed-unit is unreachable (ip=CM) while connecting to cli of Managed Unit even when the Central Manager is perfectly running and usable?
Warning: Central-manager of this managed-unit is unreachable (ip=CM)


When ping/ICMP is disabled in the environment


This is a new cli functionality introduced from v11.3 to check system components usability.
This functionality has a check for Central Manager connectivity as well.
It uses ping/ICMP to reach the Central Manager. If you have disabled ping/ICMP in your environment, this type of message can be seen while login as cli even though Central Manager is running perfectly and is usable. 
This can be ignored and does not indicate any problem.
In case you have difficulty in accessing the Guardium appliances GUI/cli, please log a case with IBM Security Guardium Technical Support Team in usual manner.
