When creating a cluster or adding hosts to a cluster using the Assisted Installer, you have an option to download the Full or Minimal Image.

When using any static networking configurations, if you try to use the Minimal ISO the host is never discovered as the static IP information is not added to the Minimal ISO. This causes the hosts to hang waiting for a DHCP IP which it never gets.

There is a description provided for both the Minimal and Full Images, however the note for the Minimal Image just states that it should be used with default networking configurations, but doesn't necessarily call out what default networking is. And the Full image states that it should be used when configuring custom networking for easier debugging.

These messages can be confusing and cause a user to start with the Minimal Image, have it fail, then download the Full image which works, but the user has no idea why.

1. Create new cluster using the Assisted Installer
2. Select Static Network Configurations
3. Add host static IP configuration
4. Generate the Minimal Discover ISO
5. Boot the host with the ISO
6. Verify the hosts networking configuration and that it's trying to get a DHCP IP.
    

Hosts are not properly discovered when using static IPs and the Minimal ISO

Users should understand the difference between the Minimal and Full ISO and when they should select each one

Since the messages are not clear, users may download the wrong image which leads to additional troubleshooting and having to download a new image.

The descriptions should be updated to state that the Full image is required when defining any Static Networking configuration and the Minimal should be used with DHCP if that's accurate.
