How to restore 'Satellite' entry deleted accidentally from 'All Hosts' page in Satellite WebUI?

Environment

• Red Hat Satellite 6.x

Issue

• How to restore the Host profile of Satellite server itself, if deleted accidentally from the All Hosts page in Satellite WebUI or via hammer_cli ?

Resolution

• Ensure that the following settings are set to true for the concerned satellite server.

  # hammer --csv settings list --fields "Name,Full name,Value" | egrep "append_domain_name_for_hosts|create_new_host|^Name" | column -s, -t
  Name                                     Full name                                Value
  append_domain_name_for_hosts             Append domain names to the host          true
  create_new_host_when_facts_are_uploaded  Create new host when facts are uploaded  true
  create_new_host_when_report_is_uploaded  Create new host when report is uploaded  true
  

• For Red Hat Satellite 6.10 and below, To get the host profile back in the WebUI, please execute the following command:

  # puppet agent -tv
  

• For any newly installed Red Hat Satellite 6.11 or later versions, please execute the following command:

  # satellite-installer --verbose
  

  • After the command completes, The puppet facts from the OS will be uploaded to the foreman database and will create the profile of the satellite server back in the Hosts-> All hosts page.

  • This new profile might not have any organization or location assigned, Hence switch to Any Organization and Any Location context and then visit the Hosts-> All hosts page.

  • In case the satellite-installer fails on the same error Host satellite.example.com does not exist in Foreman at https://satellite.example.com/, check if there isn't a Host under short name, like:

  hammer host list --search name=satellite
  

  • if there is one, delete it (hammer host delete --name=satellite) and run installer again.
  • if you can't find such one or you see more than one, check what Host foreman associated the uploaded facts for - search in /var/log/foreman/production.log for POST request like:
