NetBackup™ Snapshot Manager Install and Upgrade Guide

Before you begin migrating NetBackup Snapshot Manager

Make sure that you complete the following before installing NetBackup Snapshot Manager:

  • Ensure that your environment meets system requirements.

    See Meeting system requirements.

  • Create the instance on which you install NetBackup Snapshot Manager or prepare the physical host.

    See Verifying that specific ports are open on the instance or physical host.

    See Creating an instance or preparing the host to install NetBackup Snapshot Manager.

  • Prepare a RHEL 8.6 or 8.4 host for installation. You can either upgrade your existing RHEL 7.x OS to RHEL 8.6 or 8.4 OS, or create a new system with RHEL 8.6 or 8.4.

    • For upgrading the system from RHEL 7.x to RHEL 8.6 or 8.4, follow the Red Hat documentation.

    • For creating a new system with RHEL 8.6 or 8.4, configure a Podman container platform

      See Installing container platform (Docker, Podman).

      The brief steps include:

      • Setup the RHEL repos

        For AWS cloud, enable the extra repos

        # sudo yum-config-manager --enable rhui-REGION-rhel-server-extras

        For on-premise, enable your subscriptions:

        # sudo subscription-manager register --auto-attach --username=<username> --password=<password>

      • Install Podman if required:

        # sudo yum install -y podman

      • If SELinux is enabled, change the mode to permissive mode and restart the system.

        Edit the /etc/selinux/config configuration file and modify the SELINUX parameter value to SELINUX=permissive.

  • Run the following commands to install the required packages (lvm2, udev and dnsmaq) on the hosts:

    #yum install -y lvm2-<version>

    #yum install -y lvm2-libs-<version>

    #yum install -y systemd-udev-<version>

    #yum install -y podman-plugins

  • Run the following commands to lock the Podman and Conmon versions to the supported versions, so that they do not get updated with the yum update:

    sudo yum install -y podman-4.0.2-7.module+el8.3.1+9857+68fb1526

    sudo yum install -y python3-dnf-plugin-versionlock

  • Verify that specific ports are open on the instance or physical host.

Next, you migrate NetBackup Snapshot Manager from the RHEL 7.x host to the newly prepared RHEL 8.6 or 8.4 host.

See Migrate and upgrade NetBackup Snapshot Manager on RHEL 8.6 or 8.4.
