Removing VCS 5.0 packages

The program stops the VCS processes that are currently running during the uninstallation process.

 To uninstall VCS

1. Do one of the following to begin uninstalling:
   • If you can execute commands as superuser on the remote nodes in the cluster using ssh or rsh without supplying a password, run uninstallvcs program on one node to uninstall VCS on all nodes in the cluster.
   • If you cannot execute commands as superuser on remote nodes in the cluster using ssh or rsh, you must run uninstallvcs program on each node in the cluster.
2. Start uninstallvcs program.

   # cd /opt/VRTS/install

   # ./uninstallvcs

   The program specifies the directory where the logs are created and displays a copyright notice followed by a description of the cluster:

   VCS configuration files exist on this system with the following information:

   Cluster Name: VCS_cluster2

   Cluster ID Number: 7

   Systems: north south

   Service Groups: ClusterService groupA groupB

3. Answer the prompt to proceed with uninstalling the software.
   • To uninstall VCS on all nodes, press Enter.
   • To uninstall VCS only on specific nodes, enter n.

     Note that if you enter n or if no VCS configuration files are found on the local node, the uninstallvcs program prompts you to enter a list of nodes from which you want to uninstall VCS.

     Do you want to uninstall VCS from these systems? [y,n,q] (y)

4. Review the output as the uninstallvcs program continues to verify communication between systems and check the installations on each system to determine the packages to be uninstalled.
5. If packages, such as enterprise agents, are found to be dependent on a VCS package, the uninstaller prompt you on whether you want them removed. Enter y to remove the designated packages.
6. Review the uninstaller report after the verification.
7. Press Enter to uninstall the VCS packages.

   Are you sure you want to uninstall VCS packages? [y,n,q] (y)

8. Review the output as the uninstaller stops processes, unloads kernel modules, and removes the packages.
9. Note the location of summary and log files that the uninstaller creates after removing all the packages.
