This section explains how to change the operation state of the PRIMECLUSTER system. The operations include starting and stopping a cluster application.
The procedure for starting a cluster application is described below.
Operation Procedure:
On the RMS tree in the RMS main window, right-click the cluster application to be started, and select Online from the pop-up menu that is displayed.
The cluster application will start.
Information
You can also display the pop-up menu by right-clicking the target icon in an RMS graph or the RMS cluster table. For details on RMS graphs and the RMS cluster table, see "7.3.5 Viewing Detailed Resource Information" and "7.3.3 Concurrent Viewing of Node and Cluster Application States."
Note
To start a cluster application manually, check that the cluster application and resources under it are stopped on all nodes other than the node on which the cluster application is to be started. You can check whether they are stopped by the Offline or Standby state. With the state other than Offline or Standby, they may be running. In this case, stop them and then start the cluster application on the target node.
The procedure for stopping a cluster application is described below.
Operation Procedure:
On the RMS tree in the RMS main window, right-click the cluster application to be stopped, and select Offline from the displayed pop-up menu.
The cluster application will stop.
Information
You can also display the pop-up menu by right-clicking the target icon in an RMS graph or the RMS cluster table. For details on RMS graphs and the RMS cluster table, see "7.3.5 Viewing Detailed Resource Information" and "7.3.3 Concurrent Viewing of Node and Cluster Application States."
The procedure for switching a cluster application is described below.
Operation Procedure:
Right-click on the application object and select the Switch menu option.
A pull-down menu appears listing the available nodes for switchover.
Select the target node from the pull-down menu to switch the application to that node.
Information
You can also display the pop-up menu by right-clicking the target icon in an RMS graph or the RMS cluster table. For details on RMS graphs and the RMS cluster table, see "7.3.5 Viewing Detailed Resource Information" and "7.3.3 Concurrent Viewing of Node and Cluster Application States."
The procedure for bringing a Faulted cluster application to Online is described below
Operation Procedure:
Right-click on the cluster application object in the RMS tree, and select Clear Fault.
If you clear Fault while the cluster application is Online, RMS brings the faulted resource Online.
If you clear Fault while the cluster application is Offline, RMS brings the faulted resource Offline.
Information
You can also display the pop-up menu by right-clicking the target icon in an RMS graph or the RMS cluster table. For details on RMS graphs and the RMS cluster table, see "7.3.5 Viewing Detailed Resource Information" and "7.3.3 Concurrent Viewing of Node and Cluster Application States."
The procedure for clearing the Wait state of a node is described below.
Operation Procedure:
Right-click on the system node and select the "Online" or "Offline" option from the pop-up menu.
Note
If you clear the Wait state of a system node manually with the GUI, hvutil -u SysNode, or cftool -k, then RMS, SF, and CF assume that you have already checked that the target node is stopped.
If you clear the Wait state when the node has not been stopped, this may lead to the data corruption.
Information
You can also display the pop-up menu by right-clicking the target icon in an RMS graph or the RMS cluster table. For details on RMS graphs and the RMS cluster table, see "7.3.5 Viewing Detailed Resource Information" and "7.3.3 Concurrent Viewing of Node and Cluster Application States."
The maintenance mode is a specific mode to temporarily restrict a specified cluster application switching.
If a cluster application enters maintenance mode, switching caused by a failure of a resource or a cluster application does not occur.
Note that cluster nodes and resources are monitored during maintenance mode, and a cluster application enters the Faulted state if a failure occurs.
Maintenance mode is only allowed when PRIMECLUSTER products specified.
For using maintenance mode, see "7.3 Using maintenance mode" in "PRIMECLUSTER Reliant Monitor Services (RMS) with Wizard Tools Configuration and Administration Guide".
Note
Please note the following for using maintenance mode.
To start maintenance mode, a cluster application must be in the Online, Standby, or Offline state.
To exit maintenance mode, a cluster application and each resource must be returned in the same state before starting maintenance mode.
Do not stop RMS or the system with cluster applications in maintenance mode. Be sure to exit maintenance mode of all cluster applications before stopping RMS or the system.
For details, see "7.3.2 Maintenance mode operating notes" in "PRIMECLUSTER Reliant Monitor Services (RMS) with Wizard Tools Configuration and Administration Guide" or "Restrictions during maintenance mode" in "PRIMECLUSTER Reliant Monitor Services (RMS) Reference Guide".
