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

 

AutoDisabled

Automatically disabled.
If a engine is being operated or monitoring of the resources in a group is not finished, it cannot guarantee exclusive execution of the resource and it is set to True.

BOOLEAN

 false

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

 

*AutoStart

When the engine starts, it will notify when the group will be started automatically.

BOOLEAN

true

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

 

Enabled

It allows group to be managed.
If the attribute value is set to 'false', a group cannot be controlled.

BOOLEAN

true

O

 

*Failover

Indicates whether there is an ongoing failover due to troubles.

BOOLEAN

false

X

 

GroupName

It represents the registered name of group.

NAME

 

X

 

Locked

Permanent locking. Lock a group to prohibit all commands and operation.
Unlike temporary locking permanent, locking is maintained even after the server reboots.

BOOLEAN

false

X

 

MaxDependencyLevel

Designate the max vertical level that sets the dependencies among the resources in a group.

INTEGER

20 levels

X

 

Monitored

It indicates whether all the activated resources are monitored.

BOOLEAN

 

X

 

OnlineCount

It is the number of resource online within a group.'0' means that a group is terminated.
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 started at more than one node at the same time.
The value cannot be changed. It can be set only once when you create a group for the first time.

BOOLEAN

false

X

 

PreActive

It represents the name of node where a group was executed 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 in a group subject to operation.It is sorted in the increasing order of priority. This is the criterion used for selecting a target node when performing a failover.

STRING

 

X

 

TLocked

The attribute indicates the status of 'temporary locking'.
It operates in the same way as the locked value but it is a temporary function that will be cancelled when the engine restarts.

BOOLEAN

false

X

 

 

*AutoStart (true/false)

Determine whether to automatically start a group when making a new connection to a cluster in the system booting phase. (If the MCCS service is restarted or a single node is restarted to connect to operating MCCS, it will be ignored.)
If a parallel group is offline at a local node or some members are online, it will automatically start.
In case of a failover group, the target node with the highest priority will be automatically started first. In case of locking or troubles, a group will not be started.
