Manage Arcserve Backup Cluster Servers in NEC CLUSTERPRO/ExpressCluster

The Server Configuration Wizard lets you perform various management tasks to specify how Arcserve Backup servers function in a cluster environment. In a cluster environment, these management tasks can only be made on the active node and must also be made for all nodes within the cluster. These management tasks include the following:

• Changing the database
• Promoting a member server to a primary server
• Demoting a primary server to a member server.

To manage the Arcserve Backup Cluster Servers in NEC CLUSTERPRO/ExpressCluster

1. Stop the failover group that the Arcserve Backup is deployed on and then suspend the cluster group.

   For more information, see Stop NEC Cluster Groups.

   Note: You must stop the group to edit the group properties.

2. Remove the registry sync and edit the start.bat and stop.bat scripts to disable Arcserve Backup scripts added during installation. For more information, see Disable Arcserve Backup in NEC Cluster Scripts.

   Resume the cluster and then start the failover group.

3. From the Start menu, access the Server Configuration Wizard to run the ARCserveCfg.exe utility for the active node and make the necessary change. Do not check the "Last Cluster Node" checkbox on the last screen of the Server Configuration Wizard.
   • For more information about changing the database, see Specify a Arcserve Backup Database Application.

     Note: Local SQL Server is not supported when NEC CLUSTERPRO/ExpressCluster is used to make Arcserve Backup highly available.

   • For more information about promoting a member server to a primary server, see Promote a Member Server to a Primary Server.
   • For more information about demoting a primary server to a member server, see Demote a Primary Server to a Member Server.

   Note: When this utility is run on the first node within a cluster, it will run in the normal mode.

   The first "active" cluster node is configured for the new property and a new arcservecfg.ICF configuration file is created.

4. From the Start menu, access the Server Configuration Wizard to run the ARCServeCfg.exe utility for the new active node and make the necessary change.

   Note: When this utility is run again on any subsequent nodes in the same cluster, it will detect the existence of the arcservecfg.ICF configuration file and automatically run the utility in the cluster mode.

   The next "active" cluster node is configured for the new property.

5. Repeat steps 4 and 5 for all remaining nodes in the cluster. When you are performing this configuration procedure on the last node in the cluster, check the "Last Node" checkbox on the last screen of the Server Configuration Wizard.

   All nodes in the cluster are configured for the new property.

6. From the Cluster Manager, right-click on the group name and from the pop-up menu, select Move Group to change the active node back to the original node.

   The status of the last node will be changed to offline (passive) and the status of the original node within the cluster will be changed back to online (active).

7. Stop the failover group that the Arcserve Backup server is deployed on and then suspend cluster services.

   Rebuild the NEC Cluster Scripts and Registry Sync. For more information, see Enable Arcserve Backup in NEC Cluster Scripts.

   The new NEC HA scripts are created and the registry is synchronized.

8. Resume the cluster and then start the failover group.
