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.

AttributeDescriptionTypeDefaultEditNote
ActionState

It represents the action status for the ongoing group.
Resource online in progress: STARTING
Resource offline in progress: STOPPING
Online/offline: WATCHING

STRING

AutoFailoverDetermine whether to perform automatic failover when trouble occurs within the group.BOOLEANtrueO
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.

INTEGER0 secO
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.

BOOLEANfalseO
AutoRestartTimeoutThe wait time for the group to be checked by checking the group status automatically when Auto startsINTEGER0 secO
*AutoStartWhen the engine starts, it will notify when the group will be started automatically.BOOLEANtrueO
AutoStartNodeSet a node which group can be online while remote node being connected after MCCS main process is started.STRINGNONEO
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
BatchTimeoutDesignate the time out for running the batch file.INTEGER300 secO
*Failover

It indicates group is failing over due to failure.

BOOLEANfalseX
GroupNameIt 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.

BOOLEANfalseX
LockedTimeoutSets the time limitation in case of using the "Temporary lock" item. The locking status would be unlocked after the time you've setted hereINTEGER6hO
MaxDependencyLevelDesignate the max vertical level that sets the dependencies among the resources in a group.INTEGER20 levelsX
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.

BOOLEANfalseX
PreActiveIt shows the name of node where a group was online before.STRING
X
StateThe 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. 

BOOLEANfalseX

...

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.
