A resource group is a set of resources and MCCS failover the entire resources in a group when failure is occurred. MCCS performs failover of nodes on a group basis. Thus, you need to group the resources in the unit of failover.In addition, within a cluster, you can create multiple groups.

Attribute	Description	Type	Default	Edit	Note
ActionState	It represents the action status for the ongoing group. Resource online in progress: STARTING Resource offline in progress: STOPPING Online/offline: WATCHING	STRING		X
AutoFailover	Determine whether to perform automatic failover when trouble occurs within the group.	BOOLEAN	true	O
AutoFaultClearTIme	A failover occurs after trouble is detected, and it remains online for the given time limit. After that, all the trouble status will be removed. '0' implies that troubles are not removed.	INTEGER	0 sec	O
AutoRestart	If a group is not started because of failures in resource for detection, determine whether to automatically start it when the resource or node is normalized. It will operate properly only if AutoStart is set to true.	BOOLEAN	false	O
AutoRestartTimeout	The wait time for the group to be checked by checking the group status automatically when Auto starts	INTEGER	0 sec	O
*AutoStart	When the engine starts, it will notify when the group will be started automatically.	BOOLEAN	true	O
AutoStartNode	Set a node which group can be online while remote node being connected after MCCS main process is started.	STRING	NONE	O
BatchAfterOnline	Set the batch file to run after a group goes online. Whether the batch file is successful or failed, it does not affect the progress of a group	FILE		O
BatchBeforeOffline	Set the batch file to run before a group goes offline. Whether the batch file is successful or failed, it does not affect the progress of a group.	FILE		O
BatchTimeout	Designate the time out for running the batch file.	INTEGER	300 sec	O
*Failover	It indicates group is failing over due to failure.	BOOLEAN	false	X
GroupName	It is group name.	NAME		X
Locked	The group is permanent locked. Lock a group to prohibit all commands and operation. Unlike temporary locking permanent, locking is maintained even after the server reboots.	BOOLEAN	false	X
LockedTimeout	Sets the time limitation in case of using the "Temporary lock" item. The locking status would be unlocked after the time you've setted here	INTEGER	6h	O
MaxDependencyLevel	Designate the max vertical level that sets the dependencies among the resources in a group.	INTEGER	20 levels	XMonitored	It indicates whether all the enabled resources are monitored.	BOOLEAN	X
OnlineCount	It is the number of resource which is online within a group.'0' means that a group is offline. The number of monitoring resources (network cards) is not included in the total number.	INTEGER		X
Parallel	It is a group's parallel attributes. It indicates whether the resources in a group can be online in two nodes at the same time. The value cannot be changed. It can be set only once when you add a group for the first time.	BOOLEAN	false	X
PreActive	It shows the name of node where a group was online before.	STRING		X
State	The attribute represents the group status of node (online, offline, trouble, unchecked).	STRING		X
TargetNodeList	It is the list of nodes where a group is operated. Higher priority node will be primary node.	STRING		X
TLocked	The group is temporary locked. It operates in the same way as the locked, but it is a temporary function that will be cancelled when the engine restarts.	BOOLEAN	false	X

...

The state of the group is determined by the state of the resources.
However, the status of persistent resources like Ethernet adapter do not affect on the status of group because these resources should be online on both nodes commonly.
Basically the group may have the following states.
