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

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:

• Update the following documents:
  • https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.11/html/clusters/cluster_mce_overview#add-host-prereqs
  • https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.11/html/clusters/cluster_mce_overview#auto-add-host-prereqs

4. - [x] Mandatory for GA content:

• [x] Add steps, the diff, known issue, and/or other important
  conceptual information in the following space:
  • Need to add note about InfraEnv CR (host inventory) - one InfraEnv cannot be used for both the Auto-Add hosts and Adding hosts with the Discovery Image

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

• [ ] 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: N/A

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.

Problem: A host inventory (InfraEnv CR) cannot be used for both booting with the discovery image AND auto-add hosts. 

We need to make this clear in the docs, add a note about it, etc.

Another place it could potentially be noted or added is here: https://docs.redhat.com/en/documentation/red_hat_advanced_cluster_management_for_kubernetes/2.11/html/clusters/cluster_mce_overview#create-host-inventory-console
