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.

Object State

It represents an icon displayed when an MCCS component is in a certain condition - offline, online.

	Object State	Description	Icon
Node	EXITED	MCCS service is terminated but the system is operating.
	BUILD	MCCS service is starting. It is not yet to run an agent for each resource by receiving data from the other node.
	RUNNING	The system and the MCCS service are operating properly.
	FAULTED	All the heart-beat networks are cut off.
Group	Online	All the resources in the group are online, so the configuration element icon is displayed in color.
	Offline/ Disabled	All resources in group are offline or disabled, so the configuration element icon is displayed in black and white.
	Partial Online / GoingOnline / GoingOffline	Only some resources are online After the start command is run, all the resources are not yet to be online After the termination command is run, all the resources are not yet to be offline 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.
	Lock	A group is locked. There are two types of lock - temporary lock and normal lock. Temporary lock: When the both servers terminate the MCCS service, the locking status will be released. Lock: Even if the MCCS service is terminated, the locking status will remain the same. (For more details, refer to "5.2 Group Control".)	: Temporary lock : Lock
ResourceType	Online	All resources of the resource type are online, so the configuration element icon is displayed in color.
	Offline/ Disabled	All resources of the resource type are offline or disabled, so the configuration element icon is displayed in black and white.
	Partial Online	If only some of the resources are online, the icon in color is overlapped with a yellow check mark .
	Fault	If one or more given type of 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.
Resource	Online	When all the resources in the group are online, the configuration element icon is displayed in color.

	GoingOnline	After the online command is run, it is not yet to be online. Each resource icon is overlapped with.

	Fault	If it is switched to offline even if you did not run the termination command on the online resource, it is regarded as trouble and a red check mark will be also displayed.
	SPLIT-BRAIN	It is only applicable to a mirror disk resource. Mirror disk at the both nodes are detected as a source node, the disk icons will be displayed with on them. (For more details, refer to "Chapter8. Administrating after failure" Each Type of Trouble: Split Brain of Mirror Disk Resource).
	Pause State	It is only applicable to a mirror disk resource.When a mirror disk cannot copy data, the disk icon is overlapped with .
	Disconnection by the network	If the network disconnects a connection online, the configuration element is expressed. When the network connection is cut off, the disk icon is overlapped with .
	Disconnection by the user	If the user disconnects a connection online, the configuration element is expressed. When the network connection is cut off, the disk icon is overlapped with.
	Sync condition	When a synchronization is being performed online, the configuration element is expressed. When the synchronization is maintained, the disk icon is overlapped with .
	Disk connection cut off	The volume is recognized not as the target of copying online. When the disk connection is cut off, the disk icon is overlapped with.
	Off-site DR node role NONE	When the role of mirror disk of the off-site DR node is NONE, you will see many overlapping one another.
	Shared disk DR replication pending	The status is only applicable to a shared disk DR. When data replication is pending from shared disk from a cluster to an off-site DR node, you will see manyoverlapping one another.
