You can convert a vRealize Operations Manager data node to a replica of the master node, which adds high availability (HA) for vRealize Operations Manager.

About this task

Note:

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

If you convert a data node that is already in use for data collection and analysis, adapters and data connections that were provided through that data node fail over to other data nodes.

You may 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.

Prerequisites

  • Create nodes by deploying the vRealize Operations Manager vApp.

  • Alternatively, create nodes by running the vRealize Operations Manager Enterprise installer for Linux or Windows.

  • Create and configure the master node.

  • Create and configure a data node with a static IP address.

  • Note the fully qualified domain name (FQDN) or IP address of the master node.

Procedure

  1. In a Web browser, navigate to the master node administration interface.

    https://master-node-name-or-ip-address/admin

  2. Enter the vRealize Operations Manager administrator username 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 master 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 master node and replica node go offline, and the master remains offline for any reason while the replica goes online, the replica node does not take over the master 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/persistence.properties in a text editor.
  9. Locate and set the following properties:
    db.role=MASTER
    db.driver=/data/vcops/xdb/vcops.bootstrap
  10. Save and close persistence.properties.
  11. In the administration interface, bring the replica node online, and verify that it becomes the master node and bring the remaining cluster nodes online.

What to do next

After creating a master 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.
