Chapter 1. Upgrading Overview
Review prerequisites and available upgrade paths below before upgrading your current Red Hat Satellite installation to Red Hat Satellite 6.12.
For interactive upgrade instructions, you can also use the Red Hat Satellite Upgrade Helper on the Red Hat Customer Portal. This application provides you with an exact guide to match your current version number. You can find instructions that are specific to your upgrade path, as well as steps to prevent known issues. For more information, see Satellite Upgrade Helper on the Red Hat Customer Portal.
Note that you can upgrade Capsules separately from Satellite. For more information, see Section 1.4, “Upgrading Capsules Separately from Satellite”.
1.1. Prerequisites
Upgrading to Satellite 6.12 affects your entire Satellite infrastructure. Before proceeding, complete the following:
- Read the Red Hat Satellite 6.12 Release Notes.
- Plan your upgrade path. For more information, see Section 1.2, “Upgrade Paths”.
Plan for the required downtime. Satellite services are shut down during the upgrade. The upgrade process duration might vary depending on your hardware configuration, network speed, and the amount of data that is stored on the server.
Upgrading Satellite takes approximately 1 – 2 hours.
Upgrading Capsule takes approximately 10 – 30 minutes.
- Ensure that you have sufficient storage space on your server. For more information, see Preparing your Environment for Installation in Installing Satellite Server in a Connected Network Environment and Preparing your Environment for Installation in Installing Capsule Server.
- Back up your Satellite Server and all Capsule Servers. For more information, see Backing Up Satellite Server and Capsule Server in Administering Red Hat Satellite.
- Plan for updating any scripts you use that contain Satellite API commands because some API commands differ between versions of Satellite.
Satellite 6.12 is released only on Red Hat Enterprise Linux 8. If you are running Satellite 6.11 on Red Hat Enterprise Linux 7, you must upgrade to Red Hat Enterprise Linux 8 before you can upgrade to Satellite 6.12. For more information about upgrading from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8, see Upgrading Satellite or Capsule 6.11 to Red Hat Enterprise Linux 8 In-Place Using Leapp.
Ensure that all Satellite Servers are on the same version.
If you customize configuration files, manually or using a tool such as Hiera, these changes are overwritten when the installation script runs during upgrading or updating. You can use the --noop
option with the satellite-installer script to test for changes. For more information, see the Red Hat Knowledgebase solution How to use the noop option to check for changes in Satellite config files during an upgrade.
1.2. Upgrade Paths
You can upgrade to Red Hat Satellite 6.12 from Red Hat Satellite 6.11.
Satellite Servers and Capsule Servers on earlier versions must first be upgraded to Satellite 6.11. For more information, see the Upgrading and Updating Red Hat Satellite to 6.11.
High-Level Upgrade Steps
The high-level steps in upgrading Satellite to 6.12 are as follows:
- Optional: Clone your existing Satellite Servers. For more information, see Chapter 2, Cloning Satellite Server.
- Upgrade Satellite Server to 6.12. For more information, see Section 3.1, “Upgrading Satellite Server”.
- Upgrade all Capsule Servers to 6.12. For more information, see Section 3.3, “Upgrading Capsule Servers”.
- Continue with Section 3.5, “Performing Post-Upgrade Tasks”.
1.3. Following the Progress of the Upgrade
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. For more information, see the tmux
manual page.
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.
1.4. Upgrading Capsules Separately from Satellite
You can upgrade Satellite to version 6.12 and keep Capsules at version 6.11 until you have the capacity to upgrade them too.
All the functionality that worked previously works on 6.11 Capsules. However, the functionality added in the 6.12 release will not work until you upgrade Capsules to 6.12.
Upgrading Capsules after upgrading Satellite can be useful in the following example scenarios:
- If you want to have several smaller outage windows instead of one larger window.
- If Capsules in your organization are managed by several teams and are located in different locations.
- 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.
Chapter 2. Cloning Satellite Server
When you upgrade Satellite Server, you can optionally create and upgrade a clone of your Satellite to ensure that you do not lose any data while you upgrade. After your upgrade is complete, you can then decommission the earlier version of Satellite Server.
You can clone your Satellite Server to create instances to test upgrades and migration of instances to a different machine or operating system. This is an optional step to provide more flexibility during the upgrade or migration.
You cannot use the Satellite clone tool on a Capsule Server. Instead, you must backup the existing Capsule Server, restore it on the target server, and then reconfigure Capsule Server.
If you create a new instance of the Satellite Server, decomission the old instances after restoring the backup. Cloned instances are not supposed to run in parallel in a production environment.
Terminology
Ensure that you understand the following terms:
- Source server
- The origin of the clone.
- Target server
- The new server that you copy files to and clone the source server to.
2.1. Cloning Process Overview
- Back up the source server.
- Clone the source server to the target server.
- Power off the source server.
- Update the network configuration on the target server to match the target server’s IP address with its new host name.
- Restart goferd in Content hosts and Capsules to refresh the connection.
- Test the new target server.
2.2. Prerequisites
To clone Satellite Server, ensure that you have the following resources available:
- A minimal install of Red Hat Enterprise Linux 8 to become the target server. Do not install Red Hat Enterprise Linux 8 software groups or third-party applications. Ensure that your server complies with all the required specifications. For more information, see Preparing your Environment for Installation in Installing Satellite Server in a Connected Network Environment.
-
A backup from Satellite 6.11 that you make using the
satellite-maintain backup
script. You can use a backup with or without Pulp data. - A Satellite subscription for the target server.
Before you begin cloning, ensure the following conditions exist:
- The target server is on an isolated network. This avoids unwanted communication with Capsule Servers and hosts.
- The target server has at least the same storage capacity as the source server.
Customized configuration files
If you have any customized configurations on your source server that are not managed by the satellite-installer
tool or Satellite backup process, you must manually back up these files.
2.3. Pulp Data Considerations
You can clone Satellite server without including Pulp data. However, for your cloned environment to work, you do require Pulp data. If the target server does not have Pulp data. it is not a fully working Satellite.
To transfer Pulp data to a target server, you have two options:
- Clone using backup with Pulp data
-
Clone using backup without Pulp data and copy
/var/lib/pulp
manually from the source server.
If your pulp_data.tar
file is greater than 500 GB, or if you use a slow storage system, such as NFS, and your pulp_data.tar
file is greater than 100 GB, do not include pulp_data.tar
in the backup because this can cause memory errors during extraction. Copy the pulp_data.tar
file from the source server to the target server.
To back up without Pulp data
Follow the steps in the procedure in Section 2.4, “Cloning Satellite Server” and replace the steps that involve cloning with Pulp data with the following steps:
Perform a backup with PostgreSQL databases active excluding the Pulp data:
# satellite-maintain backup offline --skip-pulp-content \ --assumeyes /var/backup
Stop and disable Satellite services:
# satellite-maintain service stop # satellite-maintain service disable
Copy the Pulp data to the target server:
# rsync --archive --partial --progress --compress \ /var/lib/pulp/ target_server.example.com:/var/lib/pulp/
Proceed to Section 2.4.2, “Cloning to the Target Server”.
2.4. Cloning Satellite Server
Use the following procedures to clone Satellite Server. Note that because of the high volume of data that you must copy and transfer as part of these procedures, it can take a significant amount of time to complete.
2.4.1. Preparing the source server for cloning
On the source server, complete the following steps:
Verify the Pool ID of your Satellite subscription:
# subscription-manager list --consumed \ --matches 'Red Hat Satellite'|grep "Pool ID:"|awk '{print $3}'
Note the Pool ID for later use.
Remove the Red Hat Satellite subscription:
# subscription-manager remove --serial=$(subscription-manager list \ --consumed \ --matches 'Red Hat Satellite'|grep "Serial:"|awk '{print $2}')
Determine the size of the Pulp data:
# du -sh /var/lib/pulp/
If you have less than 500 GB of Pulp data, perform a backup with PostgreSQL databases active including the Pulp data. If you have more than 500 GB of Pulp data, skip the following steps and complete the steps in Section 2.3, “Pulp Data Considerations” before you continue.
# satellite-maintain backup offline --assumeyes /var/backup
Stop and disable Satellite services:
# satellite-maintain service stop # satellite-maintain service disable
Proceed to Section 2.4.2, “Cloning to the Target Server”.
2.4.2. Cloning to the Target Server
To clone your server, complete the following steps on your target server:
-
The
satellite-clone
tool defaults to using/backup/
as the backup folder. If you copy to a different folder, update thebackup_dir
variable in the/etc/satellite-clone/satellite-clone-vars.yml
file. -
Place the backup files from the source Satellite in the
/backup/
folder on the target server. You can either mount the shared storage or copy the backup files to the/backup/
folder on the target server. - Power off the source server.
Enter the following commands to register to the Customer Portal, attach subscriptions, and enable only the required subscriptions:
# subscription-manager register your_customer_portal_credentials # subscription-manager attach --pool=pool_ID # subscription-manager repos --disable=* # subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms \ --enable=rhel-8-for-x86_64-baseos-rpms \ --enable=satellite-6.11-for-rhel-8-x86_64-rpms \ --enable=satellite-maintenance-6.11-for-rhel-8-x86_64-rpms
Install the
satellite-clone
package:# dnf install satellite-clone
After you install the
satellite-clone
tool, you can adjust any configuration to suit your own deployment in the/etc/satellite-clone/satellite-clone-vars.yml
file.Run the
satellite-clone
tool:# satellite-clone
- Reconfigure DHCP, DNS, TFTP, and remote execution services. The cloning process disables these services on the target Satellite Server to avoid conflict with the source Satellite Server.
- Reconfigure and enable DHCP, DNS, and TFTP in the Satellite web UI. For more information, see Configuring External Services on Satellite Server in Installing Satellite Server in a Connected Network Environment.
Enable remote execution:
# satellite-installer --scenario satellite \ --enable-foreman-plugin-remote-execution \ --enable-foreman-proxy-plugin-remote-execution-ssh
-
Log in to the Satellite web UI, with the username
admin
and the passwordchangeme
. Immediately update the admin password to secure credentials. - Ensure that the correct organization is selected.
- In the Satellite web UI, navigate to Content > Subscriptions, then click Manage Manifest.
- Click the Refresh button, then click Close to return to the list of subscriptions.
- Verify that the available subscriptions are correct.
-
Follow the instructions in the
/usr/share/satellite-clone/logs/reassociate_capsules.txt
file to restore the associations between Capsules and their lifecycle environments. -
Update your network configuration, for example, DNS, to match the target server’s IP address with its new host name. The
satellite-clone
tool changes the host name to the source server’s host name. If you want to change the host name to something different, you can use thesatellite-change-hostname
tool. For more information, see Renaming a Satellite or Capsule Server in Administering Red Hat Satellite. -
If the source server uses the
virt-who
daemon, install and configure it on the target server. Copy all thevirt-who
configuration files in the/etc/virt-who.d/
directory from the source server to the same directory on the target server. For more information, see Configuring Virtual Machine Subscriptions in Red Hat Satellite. After you perform an upgrade using the following chapters, you can safely decommission the source server.
Chapter 3. Upgrading Red Hat Satellite
Use the following procedures to upgrade your existing Red Hat Satellite to Red Hat Satellite 6.12:
3.1. Upgrading Satellite Server
This section describes how to upgrade Satellite Server from 6.11 to 6.12. You can upgrade from any minor version of Satellite Server 6.11.
Before You Begin
- Note that you can upgrade Capsules separately from Satellite. For more information, see Section 1.4, “Upgrading Capsules Separately from Satellite”.
- Review and update your firewall configuration prior to upgrading your Satellite Server. For more information, see Preparing your environment for installation in Installing Satellite Server in a Connected Network Environment.
- Ensure that you do not delete the manifest from the Customer Portal or in the Satellite web UI because this removes all the entitlements of your content hosts.
- If you have edited any of the default job or provisioning templates, back up the files either by cloning or exporting them. Cloning is the recommended method because that prevents them being overwritten in future updates or upgrades. To confirm if a template has been edited, you can view its History before you upgrade or view the changes in the audit log after an upgrade. In the Satellite web UI, navigate to Monitor > Audits and search for the template to see a record of changes made. If you use the export method, restore your changes by comparing the exported template and the default template, manually applying your changes.
Capsule Considerations
- If you use Content Views to control updates to a Capsule Server’s base operating system, or for Capsule Server repository, you must publish updated versions of those Content Views.
- Note that Satellite Server upgraded from 6.11 to 6.12 can use Capsule Servers still at 6.11.
If you implemented custom certificates, you must retain the content of both the /root/ssl-build
directory and the directory in which you created any source files associated with your custom certificates.
Failure to retain these files during an upgrade causes the upgrade to fail. If these files have been deleted, they must be restored from a backup in order for the upgrade to proceed.
Upgrade Scenarios
- To upgrade a Satellite Server connected to the Red Hat Content Delivery Network, proceed to Section 3.1.1, “Upgrading a Connected Satellite Server”.
- To upgrade a Satellite Server not connected to the Red Hat Content Delivery Network, proceed to Section 3.1.2, “Upgrading a Disconnected Satellite Server”.
You cannot upgrade a self-registered Satellite. You must migrate a self-registered Satellite to the Red Hat Content Delivery Network (CDN) and then perform the upgrade.
FIPS mode
You cannot upgrade Satellite Server from a RHEL base system that is not operating in FIPS mode to a RHEL base system that is operating in FIPS mode.
To run Satellite Server on a Red Hat Enterprise Linux base system operating in FIPS mode, you must install Satellite on a freshly provisioned RHEL base system operating in FIPS mode. For more information, see Preparing your environment for installation in Installing Satellite Server in a Connected Network Environment.
3.1.1. Upgrading a Connected Satellite Server
Use this procedure for a Satellite Server with access to the public internet
If you customize configuration files, manually or using a tool such as Hiera, these changes are overwritten when the installation script runs during upgrading or updating. You can use the --noop
option with the satellite-installer script to test for changes. For more information, see the Red Hat Knowledgebase solution How to use the noop option to check for changes in Satellite config files during an upgrade.
Upgrade Satellite Server
Stop all Satellite services:
# satellite-maintain service stop
Take a snapshot or create a backup:
- On a virtual machine, take a snapshot.
- On a physical machine, create a backup.
Start all Satellite services:
# satellite-maintain service start
-
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. 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
- In the Satellite web UI, navigate to Hosts > Discovered hosts. On the Discovered Hosts page, power off and then delete the discovered hosts. From the Select an Organization menu, select each organization in turn and repeat the process to power off and delete the discovered hosts. Make a note to reboot these hosts when the upgrade is complete.
In the current upgrade process, you must enable the Satellite 6.12 (or Capsule) repository to restrict any updates outside the Satellite Maintenance repository. Please read the Known Issues in the Release Notes as a workaround before proceeding further.
Enable the Satellite Maintenance repository and the Satellite 6.12 repositories:
# subscription-manager repos \ --enable satellite-maintenance-6.12-for-rhel-8-x86_64-rpms \ --enable satellite-6.12-for-rhel-8-x86_64-rpms
If the Satellite 6.11 system was upgraded from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8 using Leapp, manually enable the Satellite module:
# dnf module enable satellite:el8
Check the available versions to confirm the version you want is listed:
# satellite-maintain upgrade list-versions
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 --target-version 6.12
Review the results and address any highlighted error conditions before performing the upgrade.
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/satellite.log
file to check if the process completed successfully.Perform the upgrade:
# satellite-maintain upgrade run --target-version 6.12
Determine if the system needs a reboot:
Check the version of newest installed kernel:
# rpm --query --last kernel | head -n 1
Compare this to the version of currently running kernel:
# uname --kernel-release
Optional: If the newest kernel differs from the currently running kernel, reboot the system:
# reboot
If using a BASH shell, after a successful or failed upgrade, enter:
# hash -d satellite-maintain service 2> /dev/null
3.1.2. Upgrading a Disconnected Satellite Server
Use this procedure if your Satellite Server is not connected to the Red Hat Content Delivery Network.
-
If you customized configuration files, either manually or using a tool such as Hiera, these changes are overwritten when you enter the
satellite-maintain
command during upgrading or updating. You can use the--noop
option with thesatellite-installer
command to review the changes that are applied during upgrading or updating. For more information, see the Red Hat Knowledgebase solution How to use the noop option to check for changes in Satellite config files during an upgrade. The hammer import and export commands have been replaced with
hammer content-import
andhammer content-export
tooling.If you have scripts that are using
hammer content-view version export
,hammer content-view version export-legacy
,hammer repository export
, or their respective import commands, you have to adjust them to use thehammer content-export
command instead, along with its respective import command.If you implemented custom certificates, you must retain the content of both the
/root/ssl-build
directory and the directory in which you created any source files associated with your custom certificates.Failure to retain these files during an upgrade causes the upgrade to fail. If these files have been deleted, they must be restored from a backup in order for the upgrade to proceed.
Before You Begin
- Review and update your firewall configuration before upgrading your Satellite Server. For more information, see Ports and Firewalls Requirements in Installing Satellite Server in a Disconnected Network Environment.
- Ensure that you do not delete the manifest from the Customer Portal or in the Satellite web UI because this removes all the entitlements of your content hosts.
- Back up and remove all Foreman hooks before upgrading. Reinstate hooks only after Satellite is known to be working after the upgrade is complete.
- All Satellite Servers must be on the same version.
Upgrade Disconnected Satellite Server
Stop all Satellite services:
# satellite-maintain service stop
Take a snapshot or create a backup:
- On a virtual machine, take a snapshot.
- On a physical machine, create a backup.
Start all Satellite services:
# satellite-maintain service start
-
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. 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
-
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. Remove old repositories:
# rm /etc/yum.repos.d/*
- Obtain the latest ISO files by following the Downloading the Binary DVD Images procedure in Installing Satellite Server in a Disconnected Network Environment.
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 in RHEL 8 procedure in Installing Satellite Server in a Disconnected Network Environment.Do not install or update any packages at this stage.
Configure the Satellite 6.12 repository from the ISO file.
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
Edit the
/etc/yum.repos.d/satellite.repo
file:# vi /etc/yum.repos.d/satellite.repo
Change the default
InstallMedia
repository name toSatellite-6.12
:[Satellite-6.12]
Add the
baseurl
directive:baseurl=file:///media/sat6/Satellite
Configure the Red Hat Satellite Maintenance repository from the ISO file.
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
Edit the
/etc/yum.repos.d/satellite-maintenance.repo
file:# vi /etc/yum.repos.d/satellite-maintenance.repo
Change the default
InstallMedia
repository name toSatellite-Maintenance
:[Satellite-Maintenance]
Add the
baseurl
directive:baseurl=file:///media/sat6/Maintenance/
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.Check the available versions to confirm the version you want is listed:
# satellite-maintain upgrade list-versions
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 --target-version 6.12 \ --whitelist="repositories-validate,repositories-setup"
Review the results and address any highlighted error conditions before performing the upgrade.
Perform the upgrade:
# satellite-maintain upgrade run --target-version 6.12 \ --whitelist="repositories-validate,repositories-setup"
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.
If using a BASH shell, after a successful or failed upgrade, enter:
# hash -d satellite-maintain service 2> /dev/null
Check when the kernel packages were last updated:
# rpm -qa --last | grep kernel
Optional: If a kernel update occurred since the last reboot, stop Satellite services and reboot the system:
# satellite-maintain service stop # reboot
- 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.
If you make changes in the previous step, restart Satellite services:
# satellite-maintain service restart
If you have the OpenSCAP plug-in installed, but do not have the default OpenSCAP content available, enter the following command.
# foreman-rake foreman_openscap:bulk_upload:default
- In the Satellite web UI, go to Configure > Discovery Rules and associate selected organizations and locations with discovery rules.
3.2. Synchronizing the New Repositories
You must enable and synchronize the new 6.12 repositories before you can upgrade Capsule Servers and Satellite clients.
Procedure
- In the Satellite web UI, navigate to Content > Red Hat Repositories.
- Toggle the Recommended Repositories switch to the On position.
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 6.12 (for RHEL 8 x86_64) (RPMs)
Red Hat Satellite Maintenance 6.12 (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)
NoteIf the 6.12 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.
- In the Satellite web UI, navigate to Content > Sync Status.
- Click the arrow next to the product to view the available repositories.
- Select the repositories for 6.12. Note that Red Hat Satellite Client 6 does not have a 6.12 version. Choose Red Hat Satellite Client 6 instead.
Click Synchronize Now.
ImportantIf 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.
- 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.
3.3. Upgrading Capsule Servers
This section describes how to upgrade Capsule Servers from 6.11 to 6.12.
Before You Begin
- You must upgrade Satellite Server before you can upgrade any Capsule Servers. Note that you can upgrade Capsules separately from Satellite. For more information, see Section 1.4, “Upgrading Capsules Separately from Satellite”.
- Ensure the Red Hat Satellite Capsule 6.12 repository is enabled in Satellite Server and synchronized.
- Ensure that you synchronize the required repositories on Satellite Server. For more information, see Section 3.2, “Synchronizing the New Repositories”.
- 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.
- Ensure the Capsule’s base system is registered to the newly upgraded Satellite Server.
- Ensure the Capsule has the correct organization and location settings in the newly upgraded Satellite Server.
- Review and update your firewall configuration prior to upgrading your Capsule Server. For more information, see Preparing Your Environment for Capsule Installation in Installing Capsule Server.
If you implemented custom certificates, you must retain the content of both the /root/ssl-build
directory and the directory in which you created any source files associated with your custom certificates.
Failure to retain these files during an upgrade causes the upgrade to fail. If these files have been deleted, they must be restored from a backup in order for the upgrade to proceed.
Upgrading Capsule Servers
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.
Clean yum cache:
# yum clean metadata
- Synchronize the satellite-capsule-6.12-for-rhel-8-x86_64-rpms repository in the Satellite Server.
- Publish and promote a new version of the content view with which the Capsule is registered.
The
rubygem-foreman_maintain
is installed from the Satellite Maintenance repository or upgraded from the Satellite Maintenance repository if currently installed.In the current upgrade process, you must enable the Satellite 6.12 (or Capsule) repository to restrict any updates outside the Satellite Maintenance repository. Please read the Known Issues in the Release Notes as a workaround before proceeding further.
Ensure Capsule has access to
satellite-maintenance-6.12-for-rhel-8-x86_64-rpms
and execute:# subscription-manager repos --enable \ satellite-capsule-6.12-for-rhel-8-x86_64-rpms # satellite-maintain self-upgrade
If the Capsule 6.11 system was upgraded from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8 using Leapp, manually enable the Capsule module:
# dnf module enable satellite-capsule:el8
On Capsule Server, verify that the
foreman_url
setting points to the Satellite FQDN:# grep foreman_url /etc/foreman-proxy/settings.yml
Check the available versions to confirm the version you want is listed:
# satellite-maintain upgrade list-versions
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.Use the health check option to determine if the system is ready for upgrade:
# satellite-maintain upgrade check --target-version 6.12
Review the results and address any highlighted error conditions before performing the upgrade.
Perform the upgrade:
# satellite-maintain upgrade run --target-version 6.12
Check when the kernel packages were last updated:
# rpm -qa --last | grep kernel
Optional: If a kernel update occurred since the last reboot, reboot the system:
# reboot
- 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.
- Optional: If you use custom repositories, ensure that you enable these custom repositories after the upgrade completes.
Upgrading Capsule Servers using remote execution
Create a backup or take a snapshot.
For more information on backups, see Backing Up Satellite Server and Capsule Server in Administering Red Hat Satellite.
- In the Satellite web UI , navigate to Monitor > Jobs.
- Click Run Job.
- From the Job category list, select Maintenance Operations.
- From the Job template list, select Capsule Upgrade Playbook.
- In the Search Query field, enter the host name of the Capsule.
- Ensure that Apply to 1 host is displayed in the Resolves to field.
- In the target_version field, enter the target version of the Capsule.
- In the whitelist_options field, enter the options.
- Select the schedule for the job execution in Schedule.
- In the Type of query section, click Static Query.
3.4. Upgrading the External Database
You can upgrade an external database from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8 while upgrading Satellite from 6.11 to 6.12.
Prerequisites
- Create a new Red Hat Enterprise Linux 8 based host for PostgreSQL server that follows the external database on Red Hat Enterprise Linux 8 documentation. For more information, see Using External Databases with Satellite.
Procedure
- Create a backup.
- Restore the backup on the new server.
If Satellite reaches the new database server via the old name, no further changes are required. Otherwise reconfigure Satellite to use the new name:
# satellite-installer \ --foreman-db-host newpostgres.example.com \ --katello-candlepin-db-host newpostgres.example.com \ --foreman-proxy-content-pulpcore-postgresql-host newpostgres.example.com
3.5. Performing Post-Upgrade Tasks
Some of the procedures in this section are optional. You can choose to perform only those procedures that are relevant to your installation.
Capsule synchronization might fail with deadlock after upgrading the Satellite. After the upgrade, ensure that no Capsule synchronization tasks are in progress and then stop all workers on the Capsule except one:
# systemctl stop pulpcore-worker@{2..32} # systemctl status pulpcore-worker@{1..32} | grep Active
For more information, see Red Hat Capsule 6 synchronization fails with deadlock detected errors.
3.5.1. Upgrading Discovery
If you use the PXE-based discovery process, then you must complete the discovery upgrade procedure on Satellite and on any Capsule Server with hosts that you want to be listed in Satellite on the Hosts > Discovered hosts page.
This section describes updating the PXELinux template and the boot image passed to hosts that use PXE booting to register themselves with Satellite Server.
From Satellite 6.12, provisioning templates now have a separate association with a subnet, and do not default to using the TFTP Capsule for that subnet. If you create subnets after the upgrade, you must specifically enable the Satellite or a Capsule to provide a proxy service for discovery templates and then configure all subnets with discovered hosts to use a specific template Capsule.
During the upgrade, for every subnet with a TFTP proxy enabled, the template Capsule is set to be the same as the TFTP Capsule. After the upgrade, check all subnets to verify this was set correctly.
These procedures are not required if you do not use PXE booting of hosts to enable Satellite to discover new hosts.
Additional resources
For information about configuring the Discovery service, see Configuring the Discovery Service in Provisioning Hosts.
3.5.1.1. Upgrading Discovery on Satellite Server
Update the Discovery template in the Satellite web UI:
- In the Satellite web UI, navigate to Hosts > Provisioning templates.
-
On the
PXELinux global default
line, click Clone. -
Enter a new name for the template in the Name field, for example
ACME PXE global default
. -
In the template editor field, change the line
ONTIMEOUT local
toONTIMEOUT discovery
and click Submit. - In the Satellite web UI, navigate to Administer > Settings.
-
On the Provisioning tab, set
Default PXE global template entry
to a custom value for your environment. -
Locate
Global default PXELinux template
and click on its Value. - Select the name of the newly created template from the menu and click Submit.
- In the Satellite web UI, navigate to Hosts > Provisioning templates.
- Click Build PXE Default, then click OK.
NoteIf the template is modified, a Satellite upgrade overrides it to its default version. Once the PXE Default configuration is built, the template configured in the Settings is deployed to the TFTP. This can result in deploying the default template if the new template is correctly set in the Settings.
- In the Satellite web UI, go to Configure > Discovery Rules and associate selected organizations and locations with discovery rules.
3.5.1.2. Verifying Subnets have a Template Capsule
If the Templates feature is enabled in your environment, ensure all subnets with discovered hosts have a template Capsule:
- In the Satellite web UI, navigate to Infrastructure > Subnets.
- Select the subnet you want to check.
- On the Capsules tab, ensure a Template Capsule has been set for this subnet.
For more information about configuring subnets with template Capsules, see Configuring the Discovery Service in Provisioning Hosts.
3.5.2. Upgrading virt-who
If virt-who is installed on Satellite Server or a Capsule Server, it will be upgraded when they are upgraded. No further action is required. If virt-who is installed elsewhere, it must be upgraded manually.
Before You Begin
If virt-who is installed on a host registered to Satellite Server or a Capsule Server, first upgrade the host to the latest packages available in the Satellite Client 6 repository.
Upgrade virt-who Manually
Upgrade virt-who.
# yum upgrade virt-who
Restart the virt-who service so the new version is activated.
# systemctl restart virt-who
3.5.3. Removing the Previous Version of the Satellite Tools Repository
After completing the upgrade to Satellite 6.12, the Red Hat Satellite Tools 6.11 repository can be removed from Content Views and then disabled.
Disable Version 6.11 of the Satellite Tools Repository:
- In the Satellite web UI, navigate to Content > Red Hat Repositories.
- In the Enabled Repositories area, locate Red Hat Satellite Tools 6.11 for RHEL 7 Server RPMs x86_64.
- Click the Disable icon to the right.
If the repository is still contained in a Content View then you cannot disable it. Packages from a disabled repository are removed automatically by a scheduled task.
3.5.4. Migrating Ansible Content
The upgrade from Red Hat Enterprise Linux 7 to Red Hat Enterprise Linux 8 includes an upgrade from Ansible Engine 2.9 to Ansible Core 2.12.
If you have custom Ansible content such as playbooks, job templates inside REX, roles and collections on disk, and you rely on modules being delivered by the Ansible RPM on Satellite, you have to take additional steps to adapt your Ansible installation or migrate your Ansible content.
Ansible Core contains only essential modules. In terms of FQCN notation namespace.collection.module
, you can continue to use ansible.builtin.*
, but everything else is missing in Ansible Core. That means you will be no longer able to use non-builtin Ansible modules as you were used to and you have to get them from another source, eventually.
You have the following options to handle your Ansible content after the upgrade:
You can obtain additional community-maintained collections that provide the non-essential functionality from Ansible Galaxy. For more information, see Installing collections in the Galaxy User Guide.
Note that Red Hat does not provide support for this content.
-
If you have a subscription for Red Hat Automation Hub, you can configure your
ansible-galaxy
to talk to Automation Hub server and download content from there. That content is supported by Red Hat. For more information on configuring Automation Hub connection foransible-galaxy
, see Configuring Red Hat automation hub as the primary source for content. - You can rewrite your Ansible roles, templates and other affected content. Note that Red Hat does not provide support for content that you maintain yourself.
If you want to download and install Ansible content on Capsule that does not have a connection to an external Ansible Galaxy server, then you must pass the content through Satellite Server instead of using the URL of the Ansible Galaxy server in the configuration on the Capsule directly:
- Sync the content from a Ansible Galaxy server to a custom repository on your Satellite Server.
- Configure Ansible on your Capsule to download the content from Satellite Server.
3.5.5. Reclaiming PostgreSQL Space
The PostgreSQL database can use a large amount of disk space especially in heavily loaded deployments. Use this procedure to reclaim some of this disk space on Satellite.
Procedure
Stop all services, except for the
postgresql
service:# satellite-maintain service stop --exclude postgresql
Switch to the
postgres
user and reclaim space on the database:# su - postgres -c 'vacuumdb --full --all'
Start the other services when the vacuum completes:
# satellite-maintain service start
3.5.6. Tuning Satellite Server with Predefined Profiles
If your Satellite deployment includes more than 5000 hosts, you can use predefined tuning profiles to improve performance of Satellite.
Note that you cannot use tuning profiles on Capsules.
You can choose one of the profiles depending on the number of hosts your Satellite manages and available hardware resources.
The tuning profiles are available in the /usr/share/foreman-installer/config/foreman.hiera/tuning/sizes
directory.
When you run the satellite-installer
command with the --tuning
option, deployment configuration settings are applied to Satellite in the following order:
-
The default tuning profile defined in the
/usr/share/foreman-installer/config/foreman.hiera/tuning/common.yaml
file -
The tuning profile that you want to apply to your deployment and is defined in the
/usr/share/foreman-installer/config/foreman.hiera/tuning/sizes/
directory -
Optional: If you have configured a
/etc/foreman-installer/custom-hiera.yaml
file, Satellite applies these configuration settings.
Note that the configuration settings that are defined in the /etc/foreman-installer/custom-hiera.yaml
file override the configuration settings that are defined in the tuning profiles.
Therefore, before applying a tuning profile, you must compare the configuration settings that are defined in the default tuning profile in /usr/share/foreman-installer/config/foreman.hiera/tuning/common.yaml
, the tuning profile that you want to apply and your /etc/foreman-installer/custom-hiera.yaml
file, and remove any duplicated configuration from the /etc/foreman-installer/custom-hiera.yaml
file.
- default
Number of managed hosts: 0 – 5000

Number of CPU cores: 48+
Procedure
Optional: If you have configured the
custom-hiera.yaml
file on Satellite Server, back up the/etc/foreman-installer/custom-hiera.yaml
file tocustom-hiera.original
. You can use the backup file to restore the/etc/foreman-installer/custom-hiera.yaml
file to its original state if it becomes corrupted:# cp /etc/foreman-installer/custom-hiera.yaml \ /etc/foreman-installer/custom-hiera.original
-
Optional: If you have configured the
custom-hiera.yaml
file on Satellite Server, review the definitions of the default tuning profile in/usr/share/foreman-installer/config/foreman.hiera/tuning/common.yaml
and the tuning profile that you want to apply in/usr/share/foreman-installer/config/foreman.hiera/tuning/sizes/
. Compare the configuration entries against the entries in your/etc/foreman-installer/custom-hiera.yaml
file and remove any duplicated configuration settings in your/etc/foreman-installer/custom-hiera.yaml
file. Enter the
satellite-installer
command with the--tuning
option for the profile that you want to apply. For example, to apply the medium tuning profile settings, enter the following command:# satellite-installer --tuning medium
Chapter 4. Updating Satellite Server and Capsule Server
Use this chapter to update your existing Satellite Server and Capsule Server to a new patch version, for example, from 6.12.0 to 6.12.1.
Updates patch security vulnerabilities and minor issues discovered after code is released, and are often fast and non-disruptive to your operating environment.
Before updating, back up your Satellite Server and all Capsule Servers. For more information, see Backing Up Satellite Server and Capsule Server in Administering Red Hat Satellite.
4.1. Updating Satellite Server
Prerequisites
- Ensure that you have synchronized Satellite Server repositories for Satellite, Capsule, and Satellite Client 6.
- Ensure each external Capsule can be updated by promoting the updated repositories to all relevant Content Views.
If you customize configuration files, manually or using a tool such as Hiera, these changes are overwritten when the installation script runs during upgrading or updating. You can use the --noop
option with the satellite-installer script to test for changes. For more information, see the Red Hat Knowledgebase solution How to use the noop option to check for changes in Satellite config files during an upgrade.
Updating Satellite Server to the Next Minor Version
To Update Satellite Server:
Ensure the Satellite Maintenance repository is enabled:
# subscription-manager repos --enable \ satellite-maintenance-6.12-for-rhel-8-x86_64-rpms
Check the available versions to confirm the next minor version is listed:
# satellite-maintain upgrade list-versions
Use the health check option to determine if the system is ready for upgrade. On first use of this command,
satellite-maintain
prompts you to enter the hammer admin user credentials and saves them in the/etc/foreman-maintain/foreman-maintain-hammer.yml
file.# satellite-maintain upgrade check --target-version 6.12.z
Review the results and address any highlighted error conditions before performing the upgrade.
Because of the lengthy update 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/satellite.log
file to check if the process completed successfully.Perform the upgrade:
# satellite-maintain upgrade run --target-version 6.12.z
Check when the kernel packages were last updated:
# rpm -qa --last | grep kernel
Optional: If a kernel update occurred since the last reboot, stop Satellite services and reboot the system:
# satellite-maintain service stop # reboot
4.2. Updating Disconnected Satellite Server
This section describes the steps needed to update in an Air-gapped Disconnected setup where the connected Satellite Server (which synchronizes content from CDN) is air gapped from a disconnected Satellite Server.
Complete the following steps on the connected Satellite Server.
Ensure that you have synchronized the following repositories in your connected Satellite Server.
rhel-8-for-x86_64-baseos-rpms rhel-8-for-x86_64-appstream-rpms satellite-6.12-for-rhel-8-x86_64-rpms satellite-maintenance-6.12-for-rhel-8-x86_64-rpms
-
Download the debug certificate of the organization and store it locally at, for example,
/etc/pki/katello/certs/org-debug-cert.pem
or a location of your choosing. For more information, see Creating an Organization Debug Certificate in Administering Red Hat Satellite. Create a Yum configuration file under
/etc/yum.repos.d

This downloads the contents of the repositories from the connected Satellite Server and stores them in the directory
~/Satellite-repos
.-
Verify that the RPMs have been downloaded and the repository data directory is generated in each of the sub-directories of
~/Satellite-repos
. Archive the contents of the directory
# cd ~ # tar czf Satellite-repos.tgz Satellite-repos
-
Use the generated
Satellite-repos.tgz
file to upgrade in the disconnected Satellite Server.
Perform the following steps on the disconnected Satellite Server:
-
Copy the generated
Satellite-repos.tgz
file to your disconnected Satellite Server Extract the archive to anywhere accessible by the
root
user. In the following example/root
is the extraction location.# cd /root # tar zxf Satellite-repos.tgz
