Thanks you for your update

Sorry I did not explain well my issue .

I know the command subscription-manager to enable an available repo .

In my case there is no HA repositories available through subscriptions

I have only that

yum repolist

repo id repo name

Okta-ASA Okta PAM Stable - rhel 8

codeready-builder-for-rhel-8-x86_64-eus-rhui-rpms Red Hat CodeReady Linux Builder for RHEL 8 x86_64 - Extended Update Support from RHUI (RPMs)

Ok To install the RHUI client packages on your RHEL 8 VM in Azure,

sudo dnf --config='https://rhelimage.blob.core.windows.net/repositories/rhui-microsoft-azure-rhel8.config' install 'rhui-azure-rhel8'

After installing the package, update your VM to ensure you have the latest packages:

sudo dnf update

This setup will allow your VM to access the necessary repositories through Azure's RHUI. For more detailed guidance, you can refer to the Azure documentation on RHUI.

To answer above questions , pls check serial wise

Yes, installing the High Availability (HA) package on an Azure RHEL VM may incur additional costs as The HA repository includes packages for clustering, failover, and load balancing, which typically require a **RHEL for SAP or RHEL HA subscription.**If your Azure subscription doesn’t already include RHEL HA, you might be charged for the HA add-on.You can check your current subscription details in by running
sudo subscription-manager list --available

Run the following command to uninstall the HA package:

sudo dnf remove rhui-azure-rhel8-base-ha -y

Restore the Default RHEL Base Repository

sudo dnf --config='https://rhelimage.blob.core.windows.net/repositories/rhui-microsoft-azure-rhel8.config' clean all

Perform the Upgrade:

sudo dnf update -y sudo reboot

I have answered all your questions and if it has helped you request you to kindly change the feedback from below answer to Yes from No (as I saw you have marked No) and if possible pls accept answer . Thanks

Hello , Welcome to MS Q&A

To enable the High Availability (HA) repository on your Red Hat Enterprise Linux (RHEL) 8.8 virtual machine in Azure, you can use the following command:

sudo subscription-manager repos --enable=rhel-8-server-ha-rpms

This command will enable the HA repository, allowing you to install packages related to High Availability. For more detailed guidance, you can refer to the Azure documentation on setting up Pacemaker on RHEL.
