Upgrading disconnected Red Hat Satellite to 6.16

1. Ensure that your Satellite Servers and Capsule Servers have been upgraded to Satellite 6.15. For more information, see Upgrading connected Red Hat Satellite to 6.15 or Upgrading disconnected Red Hat Satellite to 6.15.
2. If you use an external database, upgrade the external database to PostgreSQL 13. Optionally, upgrade the underlying operating system from Red Hat Enterprise Linux 8 to Red Hat Enterprise Linux 9.

3. Upgrade your Satellite Server:

   1. Upgrade your Satellite Server to 6.16.

   2. Optional: Upgrade the operating system on your Satellite Server to Red Hat Enterprise Linux 9.

      Note

      Although upgrading the operating system of your Satellite Server to Red Hat Enterprise Linux 9 is optional, you will need to do it before you can upgrade to the next Satellite version after 6.16.

   3. Synchronize the new 6.16 repositories.

4. Upgrade your Capsule Servers:

   1. Upgrade all Capsule Servers to 6.16.

   2. Optional: Upgrade the operating system on your Capsule Servers to Red Hat Enterprise Linux 9.

      Note

      Although upgrading the operating system of your Capsule Servers to Red Hat Enterprise Linux 9 is optional, you will need to do it before you can upgrade to the next Satellite version after 6.16.

1. If you want to have several smaller outage windows instead of one larger window.
2. If Capsules in your organization are managed by several teams and are located in different locations.
3. If you use a load-balanced configuration, you can upgrade one load-balanced Capsule and keep other load-balanced Capsules at one version lower. This allows you to upgrade all Capsules one after another without any outage.

Upgrade disconnected Satellite Server

1. Stop all Satellite services:

   # satellite-maintain service stop

   Copy to Clipboard

2. Take a snapshot or create a backup:

   • On a virtual machine, take a snapshot.
   • On a physical machine, create a backup.

3. Start all Satellite services:

   # satellite-maintain service start

   Copy to Clipboard
4. Optional: If you made manual edits to DNS or DHCP configuration in the /etc/zones.conf or /etc/dhcp/dhcpd.conf files, back up the configuration files because the installer only supports one domain or subnet, and therefore restoring changes from these backups might be required.

5. Optional: If you made manual edits to DNS or DHCP configuration files and do not want to overwrite the changes, enter the following command:

   # satellite-installer --foreman-proxy-dns-managed=false \
   --foreman-proxy-dhcp-managed=false

   Copy to Clipboard
6. In the Satellite web UI, navigate to Hosts > Discovered hosts. If there are discovered hosts available, turn them off and then delete all entries under the Discovered hosts page. Select all other organizations in turn using the organization setting menu and repeat this action as required. Reboot these hosts after the upgrade has completed.

7. Remove old repositories:

   # rm /etc/yum.repos.d/*

   Copy to Clipboard
8. Obtain the latest ISO files by following the Downloading the Binary DVD Images procedure in Installing Satellite Server in a disconnected network environment.

9. Create directories to serve as a mount point, mount the ISO images, and configure the rhel8 repository by following the Configuring the base operating system with offline repositories procedure in Installing Satellite Server in a disconnected network environment.

   Do not install or update any packages at this stage.

10. Configure the Satellite 6.16 repository from the ISO file.

    1. Copy the ISO file’s repository data file for the Red Hat Satellite packages:

       # cp /media/sat6/Satellite/media.repo /etc/yum.repos.d/satellite.repo

       Copy to Clipboard

    2. Edit the /etc/yum.repos.d/satellite.repo file:

       # vi /etc/yum.repos.d/satellite.repo

       Copy to Clipboard

       1. Change the default InstallMedia repository name to Satellite-6.16:

          [Satellite-6.16]

          Copy to Clipboard

       2. Add the baseurl directive:

          baseurl=file:///media/sat6/Satellite

          Copy to Clipboard

11. Configure the Red Hat Satellite Maintenance repository from the ISO file.

    1. Copy the ISO file’s repository data file for Red Hat Satellite Maintenance packages:

       # cp /media/sat6/Maintenance/media.repo /etc/yum.repos.d/satellite-maintenance.repo

       Copy to Clipboard

    2. Edit the /etc/yum.repos.d/satellite-maintenance.repo file:

       # vi /etc/yum.repos.d/satellite-maintenance.repo

       Copy to Clipboard

       1. Change the default InstallMedia repository name to Satellite-Maintenance:

          [Satellite-Maintenance]

          Copy to Clipboard

    3. Add the baseurl directive:

       baseurl=file:///media/sat6/Maintenance/

       Copy to Clipboard

12. Optional: Because of the lengthy upgrade time, use a utility such as tmux to suspend and reattach a communication session. You can then check the upgrade progress without staying connected to the command shell continuously.

    If you lose connection to the command shell where the upgrade command is running, you can see the logs in /var/log/foreman-installer/satellite.log to check if the process completed successfully.

13. Upgrade satellite-maintain to its next version:

    # satellite-maintain self-upgrade --maintenance-repo-label Satellite-Maintenance

    Copy to Clipboard

14. Use the health check option to determine if the system is ready for upgrade. When prompted, enter the hammer admin user credentials to configure satellite-maintain with hammer credentials. These changes are applied to the /etc/foreman-maintain/foreman-maintain-hammer.yml file.

    # satellite-maintain upgrade check --whitelist="repositories-validate,repositories-setup"

    Copy to Clipboard

    Review the results and address any highlighted error conditions before performing the upgrade.

15. Perform the upgrade:

    # satellite-maintain upgrade run --whitelist="repositories-validate,repositories-setup"

    Copy to Clipboard

    If the script fails due to missing or outdated packages, you must download and install these separately. For more information, see Resolving Package Dependency Errors in Installing Satellite Server in a disconnected network environment.

16. If the satellite-maintain command told you to reboot, then reboot the system:

    # reboot

    Copy to Clipboard
17. Optional: If you made manual edits to DNS or DHCP configuration files, check and restore any changes required to the DNS and DHCP configuration files using the backups that you made.

18. If you make changes in the previous step, restart Satellite services:

    # satellite-maintain service restart

    Copy to Clipboard

19. If you have the OpenSCAP plugin installed, but do not have the default OpenSCAP content available, enter the following command.

    # foreman-rake foreman_openscap:bulk_upload:default

    Copy to Clipboard
20. In the Satellite web UI, navigate to Configure > Discovery Rules. Associate selected organizations and locations with discovery rules.

Procedure

1. In the Satellite web UI, navigate to Content > Red Hat Repositories.
2. Toggle the Recommended Repositories switch to the On position.

3. From the list of results, expand the following repositories and click the Enable icon to enable the repositories:

   • To upgrade Satellite clients, enable the Red Hat Satellite Client 6 repositories for all Red Hat Enterprise Linux versions that clients use.

   • If you have Capsule Servers, to upgrade them, enable the following repositories too:

     Red Hat Satellite Capsule 6.16 (for RHEL 8 x86_64) (RPMs)

     Red Hat Satellite Maintenance 6.16 (for RHEL 8 x86_64) (RPMs)

     Red Hat Enterprise Linux 8 (for x86_64 – BaseOS) (RPMs)

     Red Hat Enterprise Linux 8 (for x86_64 – AppStream) (RPMs)

   Note

   If the 6.16 repositories are not available, refresh the Red Hat Subscription Manifest. In the Satellite web UI, navigate to Content > Subscriptions, click Manage Manifest, then click Refresh.

4. In the Satellite web UI, navigate to Content > Sync Status.
5. Click the arrow next to the product to view the available repositories.
6. Select the repositories for 6.16. Note that Red Hat Satellite Client 6 does not have a 6.16 version. Choose Red Hat Satellite Client 6 instead.

7. Click Synchronize Now.

   Important

   If an error occurs when you try to synchronize a repository, refresh the manifest. If the problem persists, raise a support request. Do not delete the manifest from the Customer Portal or in the Satellite web UI; this removes all the entitlements of your content hosts.

8. If you use content views to control updates to the base operating system of Capsule Server, update those content views with new repositories, publish, and promote their updated versions. For more information, see Managing content views in Managing content.

Upgrading Capsule Servers

1. Create a backup.

   • On a virtual machine, take a snapshot.

   • On a physical machine, create a backup.

     For information on backups, see Backing Up Satellite Server and Capsule Server in Administering Red Hat Satellite.

2. Clean yum cache:

   # yum clean metadata

   Copy to Clipboard
3. Synchronize the satellite-capsule-6.16-for-rhel-8-x86_64-rpms repository in the Satellite Server.
4. Publish and promote a new version of the content view with which the Capsule is registered.

5. Optional: Because of the lengthy upgrade time, use a utility such as tmux to suspend and reattach a communication session. You can then check the upgrade progress without staying connected to the command shell continuously.

   If you lose connection to the command shell where the upgrade command is running, you can see the logged messages in the /var/log/foreman-installer/capsule.log file to check if the process completed successfully.

6. The rubygem-foreman_maintain is installed from the Satellite Maintenance repository or upgraded from the Satellite Maintenance repository if currently installed.

   Ensure Capsule has access to satellite-maintenance-6.16-for-rhel-8-x86_64-rpms and execute:

   # satellite-maintain self-upgrade

   Copy to Clipboard

7. On Capsule Server, verify that the foreman_url setting points to the Satellite FQDN:

   # grep foreman_url /etc/foreman-proxy/settings.yml

   Copy to Clipboard

8. Use the health check option to determine if the system is ready for upgrade:

   # satellite-maintain upgrade check

   Copy to Clipboard

   Review the results and address any highlighted error conditions before performing the upgrade.

9. Perform the upgrade:

   # satellite-maintain upgrade run

   Copy to Clipboard

10. If the satellite-maintain command told you to reboot, then reboot the system:

    # reboot

    Copy to Clipboard
11. Optional: If you made manual edits to DNS or DHCP configuration files, check and restore any changes required to the DNS and DHCP configuration files using the backups made earlier.
12. Optional: If you use custom repositories, ensure that you enable these custom repositories after the upgrade completes.

Procedure

1. Install required packages:

   # satellite-maintain packages install leapp leapp-upgrade-el8toel9

   Copy to Clipboard

2. Set up the required repositories to perform the upgrade in a disconnected environment.

   Important

   The required repositories cannot be served from a locally mounted ISO but must be delivered over the network from a different machine. Leapp completes part of the upgrade in a container that has no access to additional ISO mounts.

   1. Add the following lines to /etc/yum.repos.d/rhel9.repo:

      [BaseOS]
      name=rhel-9-for-x86_64-baseos-rpms
      baseurl=http://server.example.com/rhel9/BaseOS/
      
      [AppStream]
      name=rhel-9-for-x86_64-appstream-rpms
      baseurl=http://server.example.com/rhel9/AppStream/

      Copy to Clipboard

   2. Add the following lines to /etc/yum.repos.d/satellite.repo:

      [satellite-6.16-for-rhel-9-x86_64-rpms]
      name=satellite-6.16-for-rhel-9-x86_64-rpms
      baseurl=http://server.example.com/sat6/Satellite/
      
      [satellite-maintenance-6.16-for-rhel-9-x86_64-rpms]
      name=satellite-maintenance-6.16-for-rhel-9-x86_64-rpms
      baseurl=http://server.example.com/sat6/Maintenance/

      Copy to Clipboard

3. Let Leapp analyze your system:

   # leapp preupgrade \
   --no-rhsm \
   --enablerepo BaseOS \
   --enablerepo AppStream \
   --enablerepo satellite-6.16-for-rhel-9-x86_64-rpms \
   --enablerepo satellite-maintenance-6.16-for-rhel-9-x86_64-rpms

   Copy to Clipboard

   The first run will most likely report issues and inhibit the upgrade. Examine the report in the /var/log/leapp/leapp-report.txt file, answer all questions by using leapp answer, and manually resolve other reported problems.

4. Run leapp preupgrade again and make sure that it does not report any more issues.

5. Let Leapp create the upgrade environment:

   # leapp upgrade \
   --no-rhsm \
   --enablerepo BaseOS \
   --enablerepo AppStream \
   --enablerepo satellite-6.16-for-rhel-9-x86_64-rpms \
   --enablerepo satellite-maintenance-6.16-for-rhel-9-x86_64-rpms

   Copy to Clipboard

6. Reboot the system to start the upgrade.

   After the system reboots, a live system conducts the upgrade, reboots to fix SELinux labels and then reboots into the final Red Hat Enterprise Linux 9 system.

7. Wait for Leapp to finish the upgrade. You can monitor the process with journalctl:

   # journalctl -u leapp_resume -f

   Copy to Clipboard

8. Unlock packages:

   # satellite-maintain packages unlock

   Copy to Clipboard
9. Verify the post-upgrade state. For more information, see Verifying the post-upgrade state in Upgrading from RHEL 8 to RHEL 9.
10. Perform post-upgrade tasks on the RHEL 9 system. For more information, see Performing post-upgrade tasks on the RHEL 9 system in Upgrading from RHEL 8 to RHEL 9.

11. Lock packages:

    # satellite-maintain packages lock

    Copy to Clipboard
12. Change SELinux to enforcing mode. For more information, see Changing SELinux mode to enforcing in Upgrading from RHEL 8 to RHEL 9.
