Chapter 3. Updating a disconnected Satellite Server


Update your air-gapped Satellite setup where the connected Satellite Server, which synchronizes content from CDN, is air-gapped from a disconnected Satellite Server, to the next patch version. You can follow this process to update the underlying operating system between minor release versions.

Prerequisites

Export the required repositories on the connected Satellite Server to transfer to the disconnected Satellite Server.

Procedure

  1. Synchronize the following repositories on your connected Satellite Server:

    • rhel-9-for-x86_64-baseos-rpms
    • rhel-9-for-x86_64-appstream-rpms
    • satellite-6.18-for-rhel-9-x86_64-rpms
    • satellite-maintenance-6.18-for-rhel-9-x86_64-rpms

    Ensure to set the download policy to Immediate for each repository.

  2. List the repositories to identify their IDs:

    $ hammer repository list \
    --organization-label My_Organization_Label
    Copy to Clipboard Toggle word wrap
  3. Export each repository in the syncable format:

    $ hammer content-export complete repository \
    --format syncable \
    --id My_Repository_ID
    Copy to Clipboard Toggle word wrap
  4. Transfer the exported directories to your disconnected Satellite Server.

Create local repositories on your disconnected Satellite Server.

Prerequisites

  • You have transferred the exported directories to your disconnected Satellite Server.

Procedure

  1. Locate the transferred exported directories.
  2. Create the /etc/yum.repos.d/update.repo file and update the baseurl values to point to the local file system:

    [rhel-9-for-x86_64-baseos-rpms]
    name=Red Hat Enterprise Linux 9 for x86_64 - BaseOS (RPMs)
    enabled=1
    metadata_expire=-1
    gpgcheck=0
    baseurl=file:///BaseOS_Export_Location/content/dist/rhel9/9/x86_64/baseos/os
    
    [rhel-9-for-x86_64-appstream-rpms]
    name=Red Hat Enterprise Linux 9 for x86_64 - AppStream (RPMs)
    enabled=1
    metadata_expire=-1
    gpgcheck=0
    baseurl=file:///AppStream_Export_Location/content/dist/rhel9/9/x86_64/appstream/os
    
    [satellite-6.18-for-rhel-9-x86_64-rpms]
    name=Red Hat Satellite 6.18 for RHEL 9 Server RPMs x86_64
    enabled=1
    metadata_expire=-1
    gpgcheck=0
    baseurl=file:///Satellite_Export_Location/content/dist/layered/rhel9/x86_64/satellite/6.18/os/
    
    [satellite-maintenance-6.18-for-rhel-9-x86_64-rpms]
    name=Red Hat Satellite Maintenance 6.18 for RHEL 9 Server RPMs x86_64
    enabled=1
    metadata_expire=-1
    gpgcheck=0
    baseurl=file:///Satellite_Maintenance_Export_Location/content/dist/layered/rhel9/x86_64/sat-maintenance/6.18/os/
    Copy to Clipboard Toggle word wrap

Evaluate that the system is ready for update and perform the update of the disconnected Satellite Server. Your Satellite Server does not require internet access to perform the update.

Prerequisites

  • You have prepared the required repositories on the disconnected Satellite Server.

Procedure

  1. Evaluate that the system is ready for update:

    # satellite-maintain update check --whitelist="repositories-validate,repositories-setup"
    Copy to Clipboard Toggle word wrap

    The first time you run this command, satellite-maintain prompts you to enter the Hammer admin user credentials and saves them to /etc/foreman-maintain/foreman-maintain-hammer.yml.

  2. Review the results and resolve any errors before proceeding with the update.
  3. Due to the lengthy update time, use a utility such as tmux to suspend and resume the session as needed. By using such utility, you can monitor progress without maintaining a continuous connection to the command shell.

    If you lose connection to the command shell where the update command is running, check the /var/log/foreman-installer/satellite.log file to confirm whether the process completed successfully.

  4. Perform the update:

    # satellite-maintain update run --whitelist="repositories-validate,repositories-setup"
    Copy to Clipboard Toggle word wrap
  5. If the satellite-maintain command told you to reboot, then reboot the system:

    # reboot
    Copy to Clipboard Toggle word wrap
