It manages the Windows based NetBIOS names.

SCSI reservation agents manage LUN based locking using the SCSI3-PR (Persistent Reservation) protocols that shared storages support such as SAN.
This function can prevent data losses when no nodes in a cluster know the status of other nodes.
Shared disk DR
It is the mirror set of shared disk in a cluster to an off-site DR node through WAN, so that mission critical service will be always-on from disasters.
...
Each resource type has a specific attribute value(e.g. Despite the same attribute name, it can have a different value depending on the resource).
In addition, if you change the attribute of resource type, it will be applied to all the resources of the type within the group.

| Resource General Attribute | *BatchAfterOffline | This is a batch command to be executed after a resource is taken offline. | FILE | 8 to 254 characters of text | O | ||
*BatchAfterOnline | This is a batch command to be executed after a resource is brought online. | FILE | 8 to 254 characters of text | O | |||
| *BatchBeforeOffline | This is a batch command to be executed before a resource is brought online. | FILE | 8 to 254 characters of text | O | |||
| *BatchBeforeOnline | This is a batch command to be executed before a resource is taken offline. | FILE | 8 to 254 characters of text | O | |||
| *BatchTimeout | It is the waiting time until execution of batch command completes. If execution result is over this time, it is considered as a failure. | INTEGER | 300sec | 100 to 1500 seconds | O | ||
| *CleanProgram | This program is executed to initialize related resources and state when a failure occurs to a resource. This program must be written separately. | FILE | 8 to 254 characters of text | O | |||
| *CleanTimeout | It represents the time out until execution of CleanProgram is completed. | INTEGER | 60 sec | 0 to 300 seconds | O | ||
EnableTimeout | It is the waiting time until the execution of Enable completes. If the execution result is over this time, it is considered as a failure. (unit = second) | INTEGER | INFINITY | 1 to INFINITY seconds | O | ||
| FaultOnMonitorTimeouts | If the monitoring timeout take place as much as this value, it is regarded as fault. | INTEGER | 4 times | 0 to 12 times | O | ||
| MonitorInterval | It indicates the interval to the next monitoring when online resources are monitored. If the value is too small, it may result in malfunction. | INTEGER | 10 sec | 1 to 300 seconds | O | ||
| MonitorTimeout | It represents the time elapsed until monitoring is completed or terminated. | INTEGER | 60 sec | 1 to 300 seconds | O | ||
| OfflineMonitorInterval | It is the time interval until the next monitoring of offline resource. | INTEGER | 10 sec | 0 to 300 seconds | O | ||
| *OfflineTimeout | It indicates the maximum time until resources is taken offline successfully, stop or final judgment is made. | INTEGER | 300 sec | 1 to 1500 seconds | O | ||
| *OnlineRetryLimit | It indicate the number of retry count if it fails to start resource. | INTEGER | 0 time | 0 to 10 times | O | ||
| *OnlineTimeout | It indicates the maximum time until resources is brought online successfully, stop or final judgment is made. | INTEGER | 300 sec | 1 to 1500 seconds | O | ||
| *OnlineTrustTime | It is the time to reset the retry count of resource. | INTEGER | 600 sec | 60 to 3000 seconds | O | ||
| *OnlineWaitLimit | If the timeout occurs while determining whether the resource goes online properly, it will retry as many times as defined. | INTEGER | 2 times | 0 to 30 times | O | ||
| *Restartlimit | It shows the retry count before failover when the resource is determined as a failure. | INTEGER | 0 | 0 to 100 times | Shared Disk DR X Mirror Disk DR X Other Resources O | ||
| ToleranceLimit | When the monitoring results cannot be trusted , monitoring will be retried during the defined time. | INTEGER | 0 time | 0 to 100 times | O | ||
| WaitMonitorInterval | It indicates the time interval until starting the next monitoring when monitoring resources which are waiting for online or offline. | INTEGER | 1 sec | 1 to 300 seconds | O |
