Before you begin

About this task

These steps contain information for systems that are configured for high availability using Veritas Operation Manager. If your system is not configured for high availability, ignore these additional steps.

Steps

  1. Log in as root user to the cluster node owning the cluster resources on which you want to remove Unified Manager.
  2. Stop all Unified Manager services using VCS Operations Manager or VCS commands.
  3. Stop and remove Unified Manager from the Red Hat Enterprise Linux machine: rpm -e netapp-ocum ocie-au ocie-server netapp-platform-base netapp-application-server ocie-serverbase
    This step removes all the associated NetApp RPM packages. It does not remove the prerequisite software modules, such as Java, MySQL, and p7zip.
  4. Switch to the other node by using the VCS Operations Manager.
  5. Log in to the second node of the cluster.
  6. Stop all the services, and then and remove Unified Manager from the second node: rpm -e netapp-ocum ocie-au ocie-server netapp-platform-base netapp-application-server ocie-serverbase
  7. Prevent the service group from using VCS Operations Manager or VCS commands.
  8. Optional: If appropriate, remove the supporting software modules, such as Java, MySQL, and p7zip: rpm -e p7zip mysql-community-client mysql-community-server mysql-community-common mysql-community-libs java-1.8.0

Result

After this operation is complete, the software is removed; however, MySQL data is not deleted. All the data from the /opt/netapp/data directory is moved to the /opt/netapp/data/BACKUP folder after uninstallation.
