Note: Doc team updates the current version of the documentation and the
two previous versions (n-2), but we address *only high-priority, or
customer-reported issues* for -2 releases in support.
Describe the changes in the doc and link to your dev story:

1. - [X] Mandatory: Add the required version to the Fix version/s field.

2. - [X] Mandatory: Choose the type of documentation change or review.

• [X] We need to update to an existing topic

• [ ] We need to add a new document to an existing section

• [ ] We need a whole new section; this is a function not
  documented before and doesn't belong in any current section

• [ ] We need an Operator Advisory review and approval

• [ ] We need a z-Stream (Errata) Advisory and Release note
  for MCE and/or ACM

3. - [X] *Mandatory: *Use the following link to open the doc and find where the
documentation update should go. Note: As the feature and doc is
understood and developed, this placement decision may change:

• Published doc: https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.10
• Source: https://github.com/stolostron/rhacm-docs

The segment that needs to be updated in the published documentations :

• 2.9: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.9/html-single/clusters/index#specify-ansible-inventory
• 2.10: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.10/html-single/clusters/index#specify-ansible-inventory
• 2.11: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.11/html-single/clusters/index#specify-ansible-inventory
• 2.12: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.12/html-single/clusters/index#specify-ansible-inventory

In source this is https://github.com/stolostron/rhacm-docs/blob/2.13_stage/clusters/cluster_lifecycle/ansible_config_cluster.adoc#specifying-an-ansible-inventory-to-use-for-all-jobs

4. - [ ] Mandatory for GA content:

• [ ] Add steps, the diff, known issue, and/or other important
  conceptual information in the following space:

• [ ] *Add Required access level *(example, *Cluster
  Administrator*) for the user to complete the task:

• [ ] Add verification at the end of the task, how does the user
  verify success (a command to run or a result to see?)

• [ ] Add link to dev story here:

5. - [X] Mandatory for bugs: What is the diff? Clearly define what the
problem is, what the change is, and link to the current documentation. Only
use this for a documentation bug.

The example used,

apiVersion: cluster.open-cluster-management.io/v1beta1
kind: ClusterCurator
metadata: 
  name: test-inno
  namespace: test-inno
spec: 
  desiredCuration: upgrade
  destroy: {}
  install: {}
  scale: {}
  upgrade: 
    channel: stable-4.x
    desiredUpdate: 4.x.1
    monitorTimeout: 150
    posthook: 
    - extra_vars: {}
      clusterName: test-inno
      type: post_check
      name: ACM Upgrade Checks
    prehook: 
    - extra_vars: {}
      clusterName: test-inno
      type: pre_check
      name: ACM Upgrade Checks
    towerAuthSecret: awx

seems to be pre ansible 2.4 - since then it should be using `spec.inventory` :

apiVersion: cluster.open-cluster-management.io/v1beta1
kind: ClusterCurator
metadata: 
  name: some-auto-temp
  namespace: default
  resourceVersion: "2070516"
spec: 
  install: 
    towerAuthSecret: toweraccess
    prehook: ...
    posthook: ...
  upgrade: 
    towerAuthSecret: toweraccess
    prehook: ...
    posthook: ...
  inventory: Demo Inventory

The current ansible supported versions are all way above 2.4 - a point that needs to be mentioned is that the inventory must already exist in ansible.
