You can create a single node and configure it as a primary node or create a data node in a cluster to handle additional data. All vRealize Operations installations require a primary node. With a single node cluster, administration and data functions are on the same primary node. A multiple-node vRealize Operations cluster contains one primary node and one or more nodes for handling additional data.

Prerequisites

  • Create a node by deploying the vRealize Operations vApp.
  • After it is deployed, note the fully qualified domain name (FQDN) or IP address of the node.
  • If you plan to use a custom authentication certificate, verify that your certificate file meets the requirements for vRealize Operations.

Procedure

  1. Navigate to the name or IP address of the node that will be the primary node of vRealize Operations.
    The setup wizard appears, and you do not need to log in to vRealize Operations.
  2. Click New Installation.
  3. Click Next.
  4. Enter and confirm a password for the admin user account, and click Next.
    Passwords require a minimum of eight characters, one uppercase letter, one lowercase letter, one digit, and one special character.
    The user account name is admin by default and cannot be changed.
  5. Select whether to use the certificate included with vRealize Operations or to install one of your own.
    1. To use your own certificate, click Browse, locate the certificate file, and click Open to load the file in the Certificate Information text box.
    2. Review the information detected from your certificate to verify that it meets the requirements for vRealize Operations.
  6. Click Next.
  7. Enter a name for the primary node.
    For example: Ops-Master
  8. Enter the URL or IP address for the Network Time Protocol (NTP) server with which the cluster synchronizes.
    For example: nist.time.gov
  9. Click Add.
    Leave the NTP blank to have vRealize Operations manage its own synchronization by having all nodes synchronize with the primary node and replica node.
  10. Click Next.
  11. Configure the vRealize Operations availability. To install vRealize Operations with availability, enable the Availability Mode and select High Availability or Continuous Availability. To continue your installation on full capacity, click Next .
    Note: You can enable High Availability or Continuous Availability after installation from the administrator interface.
  12. Click the Add icon to add a node.
    1. Enter the Node Name and Node Address.
    2. Select the Current Cluster Role.
    Note: This step is optional if you use the default configuration. If you select High Availability for this cluster option, you can select a node from the added list of nodes to be the replica node. Although, only one node from the list can be selected as a replica node. For more information on High Availability, see Adding High Availability to vRealize Operations. If you select Continuous Availability for this cluster, add at least one witness node and an even number of data nodes including the primary node and divide them across two fault domains. For more information, see Adding Continuous Availability.
  13. Click Next, and click Finish.
    The administration interface appears, and it takes a moment for vRealize Operations to finish adding the primary node.

Results

You have created a primary node to which you can add more nodes.

What to do next

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

  • Create and add data nodes to the unstarted cluster.
  • Create and add remote collector nodes to the unstarted cluster.
  • Click Start vRealize Operations Manager to start the single-node 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.
