Installing from OperatorHub by using web console

Complete the following steps to install InfoScale operator .

Note:

cert-manager (Red Hat-certified) must be already installed for a successful installation of InfoScale. On OCP 4.10, Node Feature Discovery (NFD) is automatically installed. You must install Node Feature Discovery (NFD) on OCP 4.11

  1. Connect to the OpenShift console and access the Catalog menu.
  2. In the left frame, click Operators > OperatorHub. You can select and install the operator here.
  3. Enter InfoScale in All Items. The InfoScale SDS Operator, InfoScale DR Manager, and the InfoScale Licensing Operator are displayed.
  4. Select the InfoScale SDS Operator and click Install in the following screen.
  5. In the following screen, select infoscale-vtas in Installed Namespace and Manual in Update approval.

    Note:

    Veritas recommends these configurations. You can select any other Namespace (including openshift-operators) for installation. Selecting Manual as the Install plan avoids automatic updates of the operator.

  6. Click Install. InfoScale installation begins as under.
  7. Wait till installation is complete. InfoScale Licensing Operator, and Node Feature Discovery Operator along with SDS operator are installed in infoscale-vtas or the namespace you provide.InfoScale Cert-manager, InfoScale Licensing Operator, and Node Feature Discovery Operator are the dependencies for InfoScale installation. If any of these dependencies are already installed in infoscale-vtas or openshift-operators, installation is skipped. License must be applied before installing InfoScale.

    If you are on OCP 4.11, follow identical steps to install Node Feature Discovery Operator .

  8. In the left frame, select Operators > Installed Operators. Check if Status of all Operators is Succeeded as under.
  9. After all these Operators are installed successfully, click NodeFeatureDiscovery in Provided APIs.

    Note:

    If NFD instance is already created, skip all steps related to Node Feature Discovery.

  10. In Node Feature Discovery Operator, click Create NodeFeatureDiscovery in the upper-right corner of the screen.
  11. After a successful creation of Node Feature Discovery, click Workloads > Pods in the left frame. Review names of the listed pods. Node Feature Discovery must be created on all nodes and is indicated by a prefix nfd.
  12. You can now apply the license. Click Operators > Installed Operators in the left frame.
  13. Click License in Provided APIs.
  14. In the screen that opens, click Create License in the upper-right corner of your screen. The following screen opens.
  15. Assign a name. Use the cluster name to associate the license with the cluster. Optionally, Enter IP address of the VIOM server on your system in licenseServer.
  16. In License Edition, select the type of license.

    See Licensing.

    Note:

    If you want to install and configure Disaster Recovery (DR), you must have Enterprise type of license.

  17. Click Create to apply the license.
  18. After the license is successfully applied, it is listed in Installed Operators > Operator details.
  19. You can click the license name for details.

    After the license is applied, you can configure the InfoScale cluster.

  20. Click Operators > Installed Operators in the left frame. You can now create an InfoScale cluster. Click InfoScale Cluster in Provided APIs.
  21. Click Create InfoScaleCluster in the upper-right corner of your screen. The following screen opens.
  22. Enter Name and InfoScale ClusterID for the cluster. If you are installing in an airgapped environment, enter Image Registry for pulling images. To install on a system with Internet connectivity, do not enter any value for Image Registry.

    Note:

    If you do not enter InfoScale ClusterID, a ClusterID is randomly generated and assigned. The ClusterID gets suffixed to the disk group.

    See Considerations for configuring cluster or adding nodes to an existing cluster to change values of Encrypted, All Shared Storage, and SameEncKey.

  23. Click InfoScale Cluster Information. Enter information about the nodes here. Enter Node name . Optionally, you can enter IP addresses of nodes in Node IPs and the device path of the disk that you want to exclude from the InfoScale disk group in Exclude-device list. You can also add fencing devices in Fencing device list. For each node, you must add two IP addresses.

    Note:

    OpenShift cluster must have at least two nodes as minimum two nodes are needed to form a cluster.

  24. To add more nodes, click Add InfoScale Cluster Information. You can add up to 16 nodes. As InfoScale supports hyperconverged architecture, all worker nodes on the OpenShift cluster must be added to the InfoScale cluster.
  25. Click Create to create an InfoScale cluster. Cluster formation begins. Watch the status message. It changes from FencingConfigured, DgCreated, and finally Running as under.

After a successful deployment of InfoScale, the diskgroup is automatically created.
