3.2. Preparing a Satellite-registered system for the upgrade

Procedure

1. Import a subscription manifest with RHEL 9 repositories into Satellite Server. For more information, see the Managing Red Hat Subscriptions chapter in the Managing Content Guide for the particular version of Red Hat Satellite.

2. Enable and synchronize all required RHEL 9 and RHEL 10 repositories on the Satellite Server with the latest updates for the source and target OS versions. Required repositories must be available in the content view and enabled in the associated activation key.

   注意

   For RHEL 10 repositories, enable the target OS version, for example, RHEL 10.0, of each repository. If you enable only the RHEL 10 version of the repositories, the in-place upgrade is inhibited.

   For example, for the Intel architecture without an Extended Update Support (EUS) subscription, enable at minimum the following repositories:

   • Red Hat Enterprise Linux 9 for x86_64 - AppStream (RPMs)

     rhel-9-for-x86_64-appstream-rpms

     x86_64 <source_os_version>

   • Red Hat Enterprise Linux 9 for x86_64 - BaseOS (RPMs)

     rhel-9-for-x86_64-baseos-rpms

     x86_64 <source_os_version>

   • Red Hat Enterprise Linux 10 for x86_64 - AppStream (RPMs)

     rhel-10-for-x86_64-appstream-rpms

     x86_64 <target_os_version>

   • Red Hat Enterprise Linux 10 for x86_64 - BaseOS (RPMs)

     rhel-10-for-x86_64-baseos-rpms

     x86_64 <target_os_version>

     Replace <source_os_version> and <target_os_version> with the source OS version and target OS version respectively, for example, 9.6 and 10.0.

     For other architectures, see RHEL 9 repositories and RHEL 10 repositories.

     For more information, see the Importing Content chapter in the Managing Content Guide for the particular version of Red Hat Satellite.

3. Attach the content host to a content view containing the required RHEL 9 and RHEL 10 repositories.

   For more information, see the Managing Content Views chapter in the Managing Content Guide for the particular version of Red Hat Satellite.

Verification

1. Verify that the correct RHEL 9 and RHEL 10 repositories have been added to the correct content view on Satellite Server.

   1. In the Satellite web UI, navigate to Content > Lifecycle > Content Views and click the name of the content view.

   2. Click the Repositories tab and verify that the repositories appear as expected.

      注意

      You can also verify that the repositories have been added to the content view by using the following commands:

      # hammer repository list --search 'content_label ~ rhel-9' --content-view <content_view_name> --organization <organization> --lifecycle-environment <lifecycle_environment>
      # hammer repository list --search 'content_label ~ rhel-10' --content-view <content_view_name> --organization <organization> --lifecycle-environment <lifecycle_environment>

      Replace <content_view_name> with the name of the content view, <organization> with the organization, and <lifecycle_environement> with the name of the lifecycle environment..

2. Verify that the correct RHEL 10 repositories are enabled in the activation key associated with the content view:

   1. In Satellite web UI navigate to Content > Lifecycle > Activation Keys and click the name of the activation key.
   2. Click the Repository Sets tab and verify that the statuses of the required repositories are Enabled.

3. Verify that all expected RHEL 9 repositories are enabled in the host. For example:

   # subscription-manager repos --list-enabled | grep "^Repo ID"
   Repo ID:   rhel-9-for-x86_64-baseos-rpms
   Repo ID:   rhel-9-for-x86_64-appstream-rpms
