Environment

• Red Hat Satellite 6

Issue

• What are the steps to change the Content View and Life Cycle Environment to another for a specific content host to fetch the repositories.?
• How to change Life Cycle Environment and Content Views for Content Hosts using the hammer command line and from Satellite Web UI?

Resolution

• First, identify the available organizations, content views, and lifecycle environments. Replace the organization name in the examples with your own:

  hammer organization list
  hammer content-view list --organization=My_Organization
  hammer lifecycle-environment list --organization=My_Organization
  

• To change the Lifecycle Environment and Content View for a specific content host using the hammer command line, run:

  hammer host update --name client.example.com --lifecycle-environment "ENV_NAME" --content-view "CV_NAME" --organization-id <ORG_ID>
  

  Note : Parameter --organization ORG_NAME can be used in place of --organization-id ORG_ID if you wish to use organization name instead of ID.

• To achieve the same through Satellite Web UI, navigate to the following page:

  Updating multiple hosts:

  • All Hosts page (New UI):

    Satellite Web UI: Hosts → All Hosts → Select Hosts → Click vertical ellipsis(⋮) near the search field → Manage content → Content view environments

    Select environment and content view and click Save

  • Content Hosts page (Old UI):

    Satellite Web UI: Hosts → Content Hosts → Select Hosts → Select Action → Change Lifecycle Environment

    Select Lifecycle Environment and Content View and click Assign

  Updating single host:

  • New Hosts UI:

    Satellite Web UI: Hosts → All Hosts → Click on the host → Click vertical ellipsis(⋮) inside Content view environment card

    Select environment and content view and click Save

  • Content Hosts UI (Old UI):

    Satellite Web UI: Hosts → Content Hosts → Click on the host → Details tab → Content Host Content → Change the Content View and Lifecycle Environment

• Changes made through the Satellite Web UI or Hammer CLI will get applied to the hosts after the next automatic subscription-manager data refresh. To apply the changes on the host immediately, perform the following steps:

  • Once the Lifecycle Environment and Content View are updated in Satellite, refresh the client host to pull new repository details:

    subscription-manager refresh
    yum clean all
    

  • Optional (manual cache removal):

    rm -rfv /var/cache/{yum,dnf}/* 
    

    This ensures that stale metadata and cached packages are cleared, allowing the host to fetch the latest repositories from Satellite.
