Role Name
2+
=========
3+
4+
This Ansible role "Red Hat Linux Installation for IBM PowerVM" automates the process of installing Red Hat Enterprise Linux (RHEL) on IBM PowerVM logical partitions (LPARs) using a **network-based installation via TFTP boot**.
5+
6+
7+
## Overview
8+
9+
This Ansible role automates the installation of Red Hat Enterprise Linux (RHEL) on IBM PowerVM logical partitions (LPARs) using a network-based TFTP boot method. It orchestrates the entire setup process including infrastructure configuration, VM provisioning, and OS deployment.
10+
11+
The role is designed to handle both existing and non-existing LPAR scenarios:
12+
13+
- If the LPAR already exists, the user can specify the `network_name` to attach the appropriate virtual network.
14+
- If the LPAR does not exist, the role will automatically create one. In this case, the user must provide values for `network_name`, `mem`, `proc` and `volume_size`. If these parameters are omitted, default values defined in the role's `vars` will be used.
15+
16+
> ⚠️ **Note:** This role does not support idempotency. Re-running the playbook may result in duplicate or conflicting configurations. This role supports single LPAR installation in a playbook run.
17+
18+
19+
## Required Infrastructure
20+
21+
To perform the installation, the following components must be configured:
22+
23+
1. **HTTP (Repo) Server**
24+
Hosts the RHEL distribution files and serves them via HTTP. This can be a dedicated server with multiple distro builds or a simple HTTP server with the required build.
25+
26+
2. **PXE Server**
27+
Runs both `tftpd` and `dhcpd` services. This role will configure these services if they are not already running.
28+
29+
3. **LPAR (Logical Partition)**
30+
The target system where RHEL will be installed. If LPAR is not available, it will be created by using the given details
31+
32+
## Role Workflow
33+
34+
1. **LPAR Existence Check and Creation**
35+
- Checks if the LPAR already exists on the HMC.
36+
- If not found, creates a new LPAR with the specified network configuration and volume size.
37+
38+
2. **MAC Address Retrieval and Formatting**
39+
- Retrieves the MAC address of the LPAR.
40+
- Converts the MAC address into colon and hyphen formats for use in DHCP and GRUB configurations.
41+
42+
3. **DHCP and TFTP Service Setup**
43+
- Checks if DHCP and TFTP services are running on the PXE server.
44+
- Installs and configures these services if not already running.
45+
- Calculates DHCP range and generates configuration using templates.
46+
47+
4. **Kickstart File Generation**
48+
- Creates a kickstart file on the repository server using a Jinja2 template.
49+
50+
5. **Boot File Preparation and GRUB Configuration**
51+
- Downloads required boot files from the repository server to the PXE server.
52+
- Creates GRUB netboot directory and configuration files.
53+
- Copies GRUB configuration to appropriate boot paths.
54+
55+
6. **DHCP Configuration Updates and Reversion**
56+
- Adds LPAR-specific DHCP entries to the PXE server configuration.
57+
- Restarts DHCP service to apply changes.
58+
- Reverts DHCP configuration after installation.
59+
60+
7. **Network Boot Initiation**
61+
- Executes `lpar_netboot` from the HMC to initiate network boot on the LPAR.
62+
63+
8. **Post-Installation Validation**
64+
- Waits for SSH availability on the LPAR.
65+
- Gathers system facts and prints OS distribution and version.
