Installing the extension on a VM

Before you install the NetBackup Snapshot Manager extension on a VM, see Prerequisites to install the extension on VM.

To install the extension

  1. Run the following respective command:
    • Interactive installation of NetBackup Snapshot Manager extension:

      # flexsnap_configure install --extension -i

    • Non interactive installation of NetBackup Snapshot Manager extension:

      # flexsnap_configure install --extension --snapshot-manager <IP/FQDN> --token <extension_token> --extname <Extension_Name>

    Note:

    Veritas recommends the use of flexsnap_configure CLI for Snapshot Manager installation. Snapshot Manager installation through docker/podman CLI is deprecated for non RHEL 8/9 and dropped for RHEL 8/ 9.

    Or

    Use the following equivalent docker/podman command to install Snapshot Manager extension:

    • For docker environment:

      # sudo docker run -it --rm -u 0
      -v /<absolute_path_of_cloudpoint_directory>:/cloudpoint 
      -v /var/run/docker.sock:/var/run/docker.sock 
      veritas/flexsnap-deploy:<version> install_extension
    • For podman environment:

      # sudo podman run -it --rm -u 0 
      -v /<absolute_path_of_cloudpoint_directory>:/cloudpoint 
      -v /run/podman/podman.sock:/run/podman/podman.sock 
      veritas/flexsnap-deploy:<version> install_extension

    Note:

    This is a single command without any line breaks.

    In this step, NetBackup Snapshot Manager does the following:

    • Creates and runs the containers for each of the NetBackup Snapshot Manager services.

    • Creates self-signed keys and certificates for nginx.

  2. Navigate to the NetBackup Web UI and follow the steps 7 and 8 described in the section Downloading NetBackup Snapshot Manager extension to generate and copy the validation token and Fingerprint.

    See Downloading the NetBackup Snapshot Manager extension.

    Note:

    For the VM-based extension you do not need to download the extension. Proceed directly to steps 7 and 8 to copy the token.

  3. Provide the following configuration parameters when prompted:

    Parameter

    Description

    IP address / FQDN

    Provide IP address or FQDN of the main NetBackup Snapshot Manager host.

    Token

    Paste the token obtained in the previous step.

    Extension Name Identifier

    Name of the extension identifier to be visible on the NetBackup UI.

    Fingerprint

    Paste the fingerprint obtained in the previous step.

    The installer then displays messages similar to the following:

    Starting docker container: flexsnap-fluentd ...done
    Starting docker container: flexsnap-ipv6config ...done
    Starting docker container: flexsnap-listener ...done

This concludes the NetBackup Snapshot Manager extension installation on a VM.

To verify that the extension is installed successfully:

  • Verify that the success message is displayed at the command prompt.

  • Verify that the extension is listed on the NetBackup Web UI.

    Navigate to Cloud > NetBackup Snapshot Manager tab > click Advanced settings > go to NetBackup Snapshot Manager extensions tab and verify.

  • Run the following command and verify that the NetBackup Snapshot Manager containers are running and the status is displayed as UP:

    # sudo docker ps -a

    The command output resembles the following:
