Introduction

Nutanix Prism Central and Prism Element updates are essential for security and performance. But manual patching risks inconsistencies, missed steps, and delays. With Ansible, you can validate upgrade readiness, schedule updates, and report results, all in a controlled and automated way.

Diagram: Prism Update Automation Flow

Use Case

• Automate pre-patch health checks
• Install Prism Central or PE hotfixes
• Schedule updates during change windows

Sample Playbook: patch_prism_services.yml

This example assumes you are using a REST API wrapper task or uri module until a dedicated Ansible module is available for LCM actions.

- name: Nutanix Prism Update Orchestration
  hosts: localhost
  gather_facts: false
  vars_files:
    - nutanix_credentials.yml
  vars:
    prism_host: "prism.example.com"
    patch_id: "PATCH-2025.07"
  tasks:

    - name: Check current Prism health
      uri:
        url: "https://{{ prism_host }}:9440/PrismGateway/services/rest/v2.0/cluster"
        method: GET
        user: "{{ nutanix_username }}"
        password: "{{ nutanix_password }}"
        force_basic_auth: true
        validate_certs: false
      register: cluster_health

    - name: Confirm cluster is healthy
      fail:
        msg: "Prism is not healthy. Aborting patch."
      when: cluster_health.json.cluster_info.state != "NORMAL"

    - name: Trigger patch download
      uri:
        url: "https://{{ prism_host }}:9440/api/nutanix/v3/lcm/entities/updates"
        method: POST
        headers:
          Content-Type: "application/json"
        body_format: json
        user: "{{ nutanix_username }}"
        password: "{{ nutanix_password }}"
        body:
          entity_ids: ["{{ patch_id }}"]
          operation_type: "DOWNLOAD_AND_INSTALL"
        force_basic_auth: true
        validate_certs: false
      register: patch_job

    - name: Report patch job status
      debug:
        msg: "Patch started. Job ID: {{ patch_job.json.status }}"

Notes on Patching Logic

• Replace patch_id with the actual ID from Nutanix LCM
• Use GET requests to monitor job status (/lcm/jobs/{job_id})
• Validate API results post-update

Scheduling the Patch

Run via cron or Ansible Tower with approval workflows for staged updates.

Summary

Patching Nutanix Prism services via Ansible removes guesswork and downtime risk. By chaining readiness checks with upgrade jobs, you ensure repeatability and reduce reliance on the GUI. Future enhancements will integrate LCM modules into the Nutanix Ansible collection for native support.
