17.9.3 Starting and stopping a system when there is planned node switching in the 1-to-1 node switching system for the Management Server

This subsection describes how to switch the executing node and standby node of the 1-to-1 node switching system for the Management Server for the issues other than errors. When the node is switched, the Application Server must be in the standby status in the standby node host.

  1. If you change the Management Server settings while the system is running, collect the Management Server settings of the executing node and copy from the executing node to the standby node. Also, execute the mstrimport command to apply the copied Management Server settings in the standby node.

    There would be same settings in the Management Server of the executing node and the Management Server of the standby node.

    For details on how to copy the Management Server settings from the executing node to the standby node and to apply the settings in the standby node, see the description related to the settings for the 1-to-1 node switching system in 17.7.4 Copying the Management Server settings from the active node to the spare node.

  2. From the Start menu, choose Control Panel - Performance and Maintenance - Management Tools, and then select Cluster Administrator.

    The Cluster Administrator starts.

  3. In the console tree (left pane), select the resource group that contains the executing node and standby node, and then from the File menu, choose Migrate Group.

    The node will switch.
