In addition to these systems, you will provision a new RHEL 8.1 based SAP HANA environment:

Lab Architecture

Ansible playbooks and workflow templates are provided to automatically provision these systems onto your student environment. As part of this process:

Overview

In this lab exercise, you will log into Tower and request a new SAP HANA environment and validate it’s correctly configured.

Logging into Tower

Your Ansible Tower instance url and credentials were supplied to you on the page created for this workshop.

Provision New RHEL SAP Environment

For your lab environment, there is a job template provided that will help you perform the initial configuration of your SAP environment:

First, run Lab 1 - Initial Setup workflow template to deploy new VMs in your environment. VMs will also be configured to receive updates from the Satellite server.

Step 1:

Select TEMPLATES from the left navigation.

Step 2:

Click the rocketship icon Add for the Lab 1 - Initial Setup

Step 3:

Sit back, watch the magic happen

One of the first things you will notice is the details section. This gives you details about your job such as who launched it, what job template it’s running, what the status is, i.e. pending, running, or complete.
