Symfoware Server V12.0.0 Cluster Operation Guide

3.6.1 Simultaneous Stopped Node Maintenance

This section explains the procedure to perform maintenance on both active and standby nodes simultaneously.

3.6.1.1 Stopping the Cluster Applications on Both Nodes for Node Maintenance

Follow the steps shown below to stop the cluster application on the active and standby nodes:

1. Start the [Cluster Admin] window.

2. Stop the cluster application.

   On the RMS tree in the [Cluster Admin] window, right-click the standby cluster application to be stopped, and select [Offline] from the pop-up menu to stop it.
   Stop the cluster application on both the active and standby nodes.

3. Stop RMS.

   On the RMS tree in the [Cluster Admin] window, right-click the system node where the cluster application to be stopped exists, and select [Shutdown RMS] from the pop-up menu to stop RMS. To perform maintenance without stopping RMS, use the hvutil -d command to change the cluster application to "Deact" state.

   Note

   • If applying the Symfoware Server update patches, RMS on the node (onto which the patches are applied) must be stopped. This is because the Symfoware monitoring process that runs when linked with PRIMECLUSTER must be stopped.

   • By stopping RMS, all cluster applications on the system node where RMS is stopped will stop. When you have multiple cluster applications configured, ensure that stopping all other cluster applications will not cause any problems, before stopping RMS.

3.6.1.2 Maintenance Tasks on Both Nodes

Perform maintenance tasks such as configuration changes, patch application, hardware and parts replacement that may require restarting.

3.6.1.3 Restarting the Cluster Applications Stopped on Both Nodes for Node Maintenance

Follow the steps shown below to restart the cluster application on the active and standby nodes.

1. Start the [Cluster Admin] window.

2. If RMS has not been started, select [Tools] >> [Start RMS] in the [Cluster Admin] window, and select the node to be started and click [Ok].

   Note that if the cluster applications were stopped for node maintenance using the hvutil -d command, execute the hvutil -a command before starting RMS.

3. Start the cluster application.

   On the RMS tree in the [Cluster Admin] window, right-click the standby cluster application, and from the pop-up menu, if you are starting the node as the active node, select [Online], or if you are starting it as the standby node, select [Standby]. If the state is [Fault], then select [Clear fault].

   This operation is not required if the cluster application has been configured to start automatically when RMS is started.
