Uninstall CA ARCserve Backup from a NEC CLUSTERPRO/ExpressCluster

Uninstalling CA ARCserve Backup from a cluster can only be made on the active node and must also be made for all nodes within the cluster.

To uninstall CA ARCserve Backup from NEC CLUSTERPRO/ExpressCluster

1. Stop the cluster group. For more information, see Stop NEC Cluster Groups.
2. Remove the registry sync and edit the start.bat and stop.bat scripts to disable CA ARCserve Backup scripts added during installation. For more information, see Disable CA ARCserve Backup in NEC Cluster Scripts.
3. Access the ARCserve Backup directory. Sort all files by type and then copy all the .dll files into a different location. (The recommended location for the copy is on the share disk so that you do not have to do a network copy later).

   Important! Make sure that the current node for the .dll files being backed up is set as the active node.

   The dynamic link library (.dll) files for CA ARCserve Backup are copied to a different location. This lets you uninstall CA ARCserve Backup from each node in the cluster.

4. From the Windows Control Panel, access the Add or Remove Programs utility, and remove CA ARCserve Backup from the current node.

   CA ARCserve Backup is removed from the current (active) node.

5. Copy the .dll files back into the original location in the ARCserve Backup directory.

   The .dll files for CA ARCserve Backup are copied back into the ARCserve Backup directory.

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.

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

7. Repeat Steps 4 through 7 for all remaining nodes in the cluster.

   CA ARCserve Backup is removed from all nodes in the cluster.

How to Verify a Cluster-aware Installation and Upgrade

This section describes how to verify CA ARCserve Backup installations and upgrades in MSCS and NEC CLUSTERPRO cluster-aware environments.

To verify a cluster-aware installation and upgrade

1. Ensure that no errors occurred during the installation or upgrade process.
2. To ensure that CA ARCserve Backup services start properly, execute the cstop script to stop all CA ARCserve Backup services and then execute the cstart script to restart all CA ARCserve Backup services.

   Note: The cstop and cstart batch files are stored in the CA ARCserve Backup installation directory on the CA ARCserve Backup server. For more information about using cstop and cstart, see the Administration Guide.

3. Open the CA ARCserve Backup Manager Console on a stand-alone server.

   Note: Do not log in to the cluster node at this time.

4. From the Manager Console on the stand-alone system, log in to the newly installed or upgraded system using the virtual name.
5. If you can successfully log in to the new system, move the ARCserve cluster group to another node. Ensure that all ARCserve services started successfully.
6. After you move the ARCserve cluster group, ensure that you can navigate the Manager Console. For example, open the Backup Manager, the Restore Manager, and the Jab Status Manager.

   Note: The Manager Console may stop responding intermittently while the cluster group is moving.

7. Open the Server Admin. Ensure that the primary server detects all member servers.
8. Open the Device Manager. Ensure that CA ARCserve Backup detects your devices.
9. Open the Job Status Manager. Ensure that all data from the previous installation migrated to the new primary server. CA ARCserve Backup migrates information about jobs, logs, and user information from the previous servers to the new primary server.
10. Submit a simple backup job on a member server.
