To enable high availability (HA) for a vRealize Operations Manager cluster, specify one of the data nodes to become a replica of the primary node.

Note: If the cluster is running, enabling HA restarts the cluster.

You can add HA to the vRealize Operations Manager cluster at installation time or after vRealize Operations Manager is up and running. Adding HA at installation is less intrusive because the cluster has not yet started.


  • Create nodes by deploying the vRealize Operations Manager vApp.
  • Create and configure the primary node.
  • Create and configure a data node with a static IP address.
  • Note the fully qualified domain name (FQDN) or IP address of the primary node.


  1. In a Web browser, navigate to the master node administration interface.
  2. Enter the vRealize Operations Manager administrator user name of admin.
  3. Enter the vRealize Operations Manager administrator password and click Log In.
  4. Under High Availability, click Enable.
  5. Select a data node to serve as the replica for the primary node.
  6. Select the Enable High Availability for this cluster option, and click OK.
    If the cluster was online, the administration interface displays progress as vRealize Operations Manager configures, synchronizes, and rebalances the cluster for HA.
  7. If the primary node and replica node go offline, and the primary remains offline for any reason while the replica goes online, the replica node does not take over the primary role, take the entire cluster offline, including data nodes and log in to the replica node command-line console as a root.
  8. Open $ALIVE_BASE/persistence/ in a text editor.
  9. Locate and set the following properties:
  10. Save and close
  11. In the administration interface, bring the replica node online, and verify that it becomes the primary node and bring the remaining cluster nodes online.

What to do next

After creating a primary replica node, you have the following options.

  • New, unstarted clusters:
    • Create and add data nodes.
    • Create and add remote collector nodes.
    • Click Start vRealize Operations Manager to start the cluster, and log in to finish configuring the product.

      The cluster might take from 10 to 30 minutes to start, depending on the size of your cluster and nodes. Do not make changes or perform any actions on cluster nodes while the cluster is starting.

  • Established, running clusters:
    • Create and add data nodes.
    • Create and add remote collector nodes.
