MCCS management allows you to access the web console to perform management by using the web service.
Only if all the node engines are running, you can connect the management web console to MCCS service.
If any one of nodes is not running, other node will standby until it finished initialization and configuration.

    In these cases, the icon in color is overlapped with a yellow check mark .

Fault

If one or more resources are switched to offline even if you did not run the termination command, it is regarded as trouble and a red check mark will be also displayed.
