Before you begin migrating NetBackup Snapshot Manager for Data Center
Ensure that you complete the following before installing NetBackup Snapshot Manager for Data Center:
Ensure that your environment meets system requirements.
Create the instance on which you install NetBackup Snapshot Manager for Data Center 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 for Data Center.
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:
Enable your subscriptions:
# sudo subscription-manager register --auto-attach --username=<username> --password=<password>
Install Podman if required:
# sudo yum install -y podman
SELinux Enforcing mode is supported for RHEL 8/9.
Run the following commands to install the required packages (
lvm2,udev,dnsmaq,udica, andpolicycoreutils-devel) 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
# yum install -y udica
# yum install -y policycoreutils-devel
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, migrate NetBackup Snapshot Manager for Data Center from the RHEL 7.x host to the newly prepared RHEL 8.6 or 8.4 host.
