The Domain Management Server resource manager (IBM.DMSRM) controls the managed node (IBM.ManagedNode) resource class and the node group (IBM.NodeGroup) resource class. The Domain Management Server resource manager runs on the node designated as the management server and is automatically started by the RMC subsystem.
The Domain Management Server resource manager is part of CSM. For information about the resource managers that are available with RSCT, see IBM RSCT for Linux: Guide and Reference.
The program name of this resource class is IBM.ManagedNode. It runs on the management server and is started by the RMC subsystem. It is controlled by the Domain Management Server resource manager.
For details about the attributes of the Managed Node class, see the nodeattributes man page or nodeattributes File.
The following predefined conditions are available for the IBM.ManagedNode resource class.

---|---|---|---|---|
PowerStatus !=1
| An event is generated whenever the power state of the node is no longer 1 (on). This typically happens when the node is powered off, or when the power status of the node cannot be determined. |
PowerStatus =1
|
The event is rearmed when the node is powered on again.
| NodeNames = {localnode} |
The program name of the Node Group Resource Class is IBM.NodeGroup. The node group resource class runs on the management server.
