Enable CA ARCserve Backup in NEC Cluster Scripts

Cluster scripts and registry keys are inserted during the NEC post-setup process. During the upgrade process from BrightStor ARCserve Backup r11.5 to this release, part of the cluster scripts are disabled and the registry key is deleted. When the upgrade is finished, these cluster scripts need to be enabled and registry keys need to be rebuilt.

Note: This section contains graphics that correspond with NEC CLUSTERPRO/ExpressCluster version 8.0. If you are running a more recent version of NEC CLUSTERPRO/ExpressCluster, see your NEC CLUSTERPRO/ExpressCluster documentation.

To enable the NEC Cluster Scripts and Registry Key

1. Access Cluster Manager.

   The Cluster Manager dialog appears.

   Note: Cluster Manager is a utility provided by NEC and is installed on servers that have NEC CLUSTERPRO/ExpressCluster installed. From the Cluster Manager, you perform most of the configuration and management tasks associated with clusters.

2. Select the NEC Group that the ARCserve server is deployed in, and locate the corresponding ARCserve cluster resources. Right-click on each ARCserve cluster resource and from the pop-up menu, select Property.

   The Group property dialog appears.

3. Select the Reference and Change option. When the Group properties dialog opens, select the Script tab.

   The Script tab dialog appears.

4. From the Script list, select start.bat and click Edit. When the start.bat script appears, locate the REM SET process script (two places) and set the value to 1 as follows:

   SET process=1
   

   Note: In the start.bat file, the REM SET process script is located after NORMAL and after FAILOVER.

   The start.bat script is modified.

5. From the Script list, select stop.bat and click Edit. When the stop.bat script appears, locate the REM SET process script (two places) and set the value to 1 as follows:

   SET process=1
   

   Note: In the stop.bat file, the REM SET process script is located after NORMAL and after FAILOVER.

   The stop.bat script is modified.

6. From the Group properties dialog, select the Registry tab. When the Registry dialog opens, click Add.

   The Add/Change registry key dialog appears.

7. Add the Registry key and click OK.

   The Registry key is added to the Registry key list on the Group Properties dialog.

Upgrade CA ARCserve Backup from r12 or r12.5 to r15 in an NEC CLUSTERPRO Environment

This section describes the steps you must perform to upgrade from earlier software versions to the current release. Please ensure you are following the appropriate upgrade procedure:

• To upgrade BrightStor ARCserve Backup r11.5, including the latest service packs, in an NEC CLUSTERPRO cluster-aware environment, directly to r12.5, follow the steps in Upgrade CA ARCserve Backup from r11.5 to r15 in an NEC CLUSTERPRO Environment.
• To upgrade CA ARCserve Backup r12/r12.5, including the latest service packs, to r15 in an NEC CLUSTERPRO environment, follow this procedure.

Before you begin, ensure you have read the information in Upgrade CA ARCserve Backup from a Previous Release.

When upgrading CA ARCserve Backup from r12/r12.5 to r15 in an NEC CLUSTERPRO environment, the following procedure must be performed to safely protect your clustered backup data. If you are not already using CA ARCserve Backup r12/r12.5 in a cluster environment, you do not need to perform this procedure. The procedure supports the following CA ARCserve Backup r12/r12.5 upgrade scenarios in an NEC CLUSTERPRO environment:

• Primary server upgrade SQL Server to SQL Server
• Primary server upgrade SQL Server Express to SQL Server Express
• Member server upgrade to r15 Member server

This upgrade procedure is assuming you are operating in a two-node cluster environment, with Node A representing the initial Active Node and Node B representing the initial Passive Node.

In the diagram, the upgrade steps are illustrated.

To upgrade CA ARCserve Backup from r12/r12.5 to r15 in an NEC CLUSTERPRO environment

On Node A:

1. Disable the NEC Cluster Scripts and delete the Registry Sync. For more information, see Disable CA ARCserve Backup in NEC Cluster Scripts.
2. Copy the CA ARCserve Backup r12/r12.5 installation directory files into a temporary location.

   A backup copy of the CA ARCserve Backup r12/r12.5 files is located in a different location from the original files.

3. Perform CA ARCserve Backup r15 upgrade installation for Node A. For more information, see Upgrade CA ARCserve Backup from a Previous Release.

   The installation path location for the CA ARCserve Backup r15 upgrade must be the same location where r12 is currently installed.

   CA ARCserve Backup for Node A is upgraded from r12/r12.5 to r15. Do not set up new ARCserve cluster resources at this time.

4. Move the active node from Node A to Node B, as follows:
   1. Access the Cluster Manager. The Cluster Manager dialog opens.

      Note: Cluster Manager is a utility provided by NEC and is installed on servers that have NEC CLUSTERPRO installed. Cluster Manager is accessed from the NEC ExpressCluster Server group of the Start menu. From Cluster Manager, you can perform most of the configuration and management tasks associated with clusters.

   2. Select the NEC Group in which the ARCserve server is deployed and locate the corresponding ARCserve cluster resources. Right-click on each ARCserve cluster resource and select Move Group from the shortcut menu.
      • If there are only two nodes in the cluster, the active node status is automatically transferred from the initial active node (Node A) to the other node (Node B), making Node B active and Node A passive.
      • If there are more than two nodes in the cluster, a pop-up screen opens, allowing you to select the node to which you want to transfer the active status. When you select the node for transfer, the node you specified becomes active and the previously-selected node becomes passive. Repeat this procedure for each node in the cluster.

On Node B:

1. Copy the CA ARCserve Backup r12/r12.5 installation directory files from the temporary location back into the original location.

   The CA ARCserve Backup r12/r12.5 files are now located back in the original location.

2. Do one of the following:
   • Continue to the next step if you are upgrading a member server or a primary server that uses a remote deployment of Microsoft SQL Server to host the CA ARCserve Backup database.
   • For all other upgrades, do the following:
     1. Access the following directory on the shared disk in the cluster-aware environment:

            ARCserve_Home\SQLASDB\data
        

        Select all of the files in the above directory.

        Right-click the selected files and click Properties on the pop-up menu.

        The Properties dialog opens.

     2. Click the Security tab.

        Click Add and select the Network Service security group.

        Set the Network Service security group permissions to Allow Full Control.

        Click OK, and then click OK on the Properties dialog.

3. Perform CA ARCserve Backup r15 upgrade installation for Node B with the same settings selected for Node A (domain name, server type, install path, installed options, and so on). For more information, see Upgrade CA ARCserve Backup from a Previous Release.
4. Rebuild the NEC Cluster Scripts and Registry Sync. For more information, see Enable CA ARCserve Backup in NEC Cluster Scripts.

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

Note: CA ARCserve Backup does not support recovering the CA ARCserve Backup database when the last backup of the CA ARCserve Backup database was completed before you upgraded to this release. As a best practice, you should back up the CA ARCserve Backup database as soon as possible after the upgrade is complete. For information about backing up the CA ARCserve Backup database, see the Administration Guide.
