Resources are necessary H/W or S/W elements for service operation and they include network interface cards(NIC), IP addresses, processes, services, and disks.
In MCCS, resource is used as the minimum unit of operation management with high availability.
When you create a resource in MCCS, you must enter a unique name that is used to differentiate a resource from others.
Thus, the existing names or reserved keywords (for instance, network interface cards (NIC) or processes) cannot be used as names.
Depending on the type of operation, resources are classified into general resource (OnOff) that issue commands and monitor resources (None).
Most of resources are general resources that can go online or offline depending on the resource condition in MCCS.
To the contrary, monitor resources cannot go online or offline but they can only provide monitoring.
For instance, a network card can only monitor whether it exists physically or it is normal, and a network address can use an online/offline command to assign or cancel a virtual IP address.
Agents are responsible for commanding and monitoring resources.

The resource goes offline.
Just like the start command, there is a sub menu where you can select a node.
The command is activated when there exists an online node.
You should note whether there are the parent resources online. The parent resource depends on the selected resource when it uses the Terminate command.
So, when you use the Terminate command, you should first terminate the parent resource which is in the reverse order of Start command.
Thus, when MCCS runs the Terminate command, if the online parent resource exists, it will first check whether to terminate the parent resource first.


Offline Propagation

You can take a resource offline by using this. 
Similar to Online, you can choose appropriate node from the sub menu.
You can take a resource including parent resources offline by using this.

 

Clear Fault

The sign of failure is still displayed for the failed resource. Until the manager takes necessary actions, you cannot start the resource in the node.
In other words, it is waiting for the manager's actions. After troubleshooting, if you want to resume MCCS operation, the sign of failure should be removed.
Use the command for this purpose. 'Remove Sign of Resource Failure' is applicable to one resource but 'Remove Sign of Group Failure' is applicable to all the resources in the group.
