Resource attribute is a reference value used when the resource takes some actions or determines the status.
Resource attribute can be identified from Resource Attributes view of MCCS web console.
From the group management view of MCCS web console, select the resource, then select ‘Resource Attributes’ tab located on the top of detailed information panel.
The values of gray colored are read only. They just contain and show the information of resource state.
The values of white colored are configurable by user definition. Below is description of some of them.

Among the attributes listed on the following tables, those with the * marks do not work on the network card resources that is unable to use the online/offline command. |
| Attribute | Description | Type | Default | Minimum Value/ Maximum Value | Edit | Note | |
|---|---|---|---|---|---|---|---|
| Key Attribute | Critical | When a failure occurs in the resource it indicated whether to failover the group. | BOOLEAN | X | |||
| Enabled | It is used when deciding whether to manage the resource. | BOOLEAN | X | ||||
| General Attribute | AgentState | It indicates the agent state of the resource. | STRING | X | |||
*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. When the limit is exceeded, it will be forcefully stoped. | 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 | ||
| *Failoverable | It indicates whether the resource is in the state to be failover. | BOOLEAN | X | ||||
| FaultOnMonitorTimeouts | If the monitoring timeout take place as much as this value, it is regarded as fault. If it is '0', it is not regarded as fault. | INTEGER | 4 times | 0 to 12 times | O | ||
| Group | It is the name of the group which the resource belongs. | STRING | 4 to 50 characters of text | X | |||
| *LastOnline | It is name of the node on which state of the resource is online lastly. | STRING | X | ||||
| Monitored | Depending on the 'MonitorTimeout', attribute values for the resource types, it record periodically whether each node's monitoring is completed. | BOOLEAN | X | ||||
| 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. If the value is too big, then it will take too long until it detects the status changes. | 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 | ||
| NoAction | It represents the action attribute of the resource. | BOOLEAN | X | ||||
| OfflineMonitorInterval | It is the time interval until the next monitoring of offline resource. If the time interval is '0', the offline resources will not be monitored. | 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. If resources remain normal for a specified amount of time after starting, the retry count will be initialized. | 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. It is the time interval of retry is defined in 'MonitorInterval'. | INTEGER | 2 times | 0 to 30 times | O | ||
| Persist | It is used when deciding whether to manage the resource. Persist Resource just has two resource state Online and fault. | BOOLEAN | X | ||||
| ResName | It is the name of the resource. | NAME | 4 to 50 characters of text | X | |||
| *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 | ||
| State | It is the resource state of each node. | STRING | X | ||||
| ToleranceLimit | When the monitoring results cannot be trusted , monitoring will be retried during the defined time. For instance, if the result of the ICMP ping test with a network interface card cannot be trusted, it must be retried as many times as defined. | INTEGER | 0 time | 0 to 100 times | O | ||
| Type | It is the name of the agent type of the resource. | STRING | X | ||||
| 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 | ||

Copied resource name is defined which "_number" is added from original name by default and this can be editable. Depending on the resource type, you need to enter extra information if necessary. |
