7.1.2 CRM Main Window

When you monitor the state of the PRIMECLUSTER system, the CRM main window allows you to view the states of the resources managed by the cluster resource management facility and identify failed hardware.

This section describes resource states and operation methods related to hardware resources.

See

The CRM main window is a screen of the cluster resource monitoring facility. See "crm" in "4.5.3 Cluster Admin Functions."

7.1.2.1 Displayed Resource Types

This section shows the resources associated with the hardware resources that are displayed in the CRM main window.

The detailed resource information lists the icons that are used in the CRM main window.

7.1.2.1.2 Resource States

In the CRM main window, the displayed icon types and states differ for each resource class.
For each resource, an icon that indicates a failure (OFF-FAIL or ON-FAILOVER) is displayed if there is a fault in a subordinate resource. In the CRM tree view, expand the icons sequentially from cluster icon to node icons to subordinate resource icons, and identify the faulted resource. If the resource state is OFF-FAIL or ON-FAILOVER, see "7.4 Corrective Actions for Resource Failures," and take corrective actions.
If the resource state is ON, OFF-STOP, or UNKNOWN, you do not need to take any corrective actions.

Initial setup

Select this item to set up the resource database to be managed by the cluster resource management facility. Select Tool -> Initial setup to display the Initial Configuration Setup screen. The initial configuration setup cannot be operated simultaneously from multiple clients. See "5.1.3.1 Initial Configuration Setup."

Start

This menu item activates the selected resource. The start operation is executed during maintenance work. If the selected resource is registered to a cluster application, the start operation can be executed only when that cluster application is in the Deact state. Use the RMS main window to check the cluster application state.

Note

  • After completing the maintenance work, be sure to return the resource that you worked on to its state prior to the maintenance.

  • If the resource that was maintained is registered to a cluster application, be sure to stop the resource before clearing the Deact state of the application.

Stop

This menu item deactivates the selected resource. The stop operation is executed during maintenance work. If the selected resource is registered to a cluster application, the startup operation can be executed only when that cluster application is in the Deact state. Use the RMS main window to check the cluster application state.

Note

  • After completing the maintenance work, be sure to return the resource that you worked on to its state prior to the maintenance.

  • If the resource that was maintained is registered to a cluster application, be sure to stop the resource before clearing the Deact state of the application.

Note

If a message is displayed during operating at the CRM main window and the frame title of the message dialog box is "Cluster resource management facility," then see "3.2 CRM View Messages" and "Chapter 4 FJSVcluster Format Messages" in "PRIMECLUSTER Messages."
