Prerequisites

• You have completed the graphical installation according to the recommended workflow described on Installing RHEL using an ISO image from the Customer Portal.
• You have an active, non-evaluation Red Hat Enterprise Linux subscription.

• Using the Red Hat Content Delivery Network (CDN) to register your system, attach RHEL subscriptions, and install Red Hat Enterprise Linux. See Register and install from CDN using GUI for more information.
• During installation using Initial Setup.
• After installation using the command line.
• After installation using the Subscription Manager user interface. See Subscription manager post install UI for more information.
• After installation using Registration Assistant. Registration Assistant is designed to help you choose the most suitable registration option for your Red Hat Enterprise Linux environment. See https://access.redhat.com/labs/registrationassistant/ for more information.

Prerequisites

• You have an active, non-evaluation Red Hat Enterprise Linux subscription.
• Your Red Hat subscription status is verified.
• You have not previously received a Red Hat Enterprise Linux 8 subscription.
• You have activated your subscription before attempting to download entitlements from the Customer Portal. You need an entitlement for each instance that you plan to use. Red Hat Customer Service is available if you need help activating your subscription.
• You have successfully installed Red Hat Enterprise Linux 8  and logged into the system as root.

Prerequisites

• You have completed the graphical installation as per the recommended workflow described on Installing RHEL using an ISO image from the Customer Portal.
• You have an active, non-evaluation Red Hat Enterprise Linux subscription.
• Your Red Hat subscription status is verified.

Prerequisites

• You installed and registered your Red Hat Enterprise Linux 8 system, but System Purpose is not configured.

• You are logged in as a root user.

  Note

  If your system is registered but has subscriptions that do not satisfy the required purpose, you can run the subscription-manager remove --all command to remove attached subscriptions. You can then use the command-line subscription-manager syspurpose {role, usage, service-level} tools to set the required purpose attributes, and lastly run subscription-manager attach --auto to re-entitle the system with considerations for the updated attributes.

  Procedure

  Complete the steps in this procedure to configure System Purpose after installation using the subscription-manager syspurpose command-line tool. The selected values are used by the entitlement server to attach the most suitable subscription to your system.

  1. From a terminal window, run the following command to set the intended role of the system:

     # subscription-manager syspurpose role --set "VALUE"

     Replace VALUE with the role that you want to assign:

     • Red Hat Enterprise Linux Server
     • Red Hat Enterprise Linux Workstation
     • Red Hat Enterprise Linux Compute Node

     For example:

     # subscription-manager syspurpose role --set "Red Hat Enterprise Linux Server"

     1. Optional: Before setting a value, see the available roles supported by the subscriptions for your organization:

        # subscription-manager syspurpose role --list

     2. Optional: Run the following command to unset the role:

        # subscription-manager syspurpose role --unset

  2. Run the following command to set the intended Service Level Agreement (SLA) of the system:

     # subscription-manager syspurpose service-level --set "VALUE"

     Replace VALUE with the SLA that you want to assign:

     • Premium
     • Standard
     • Self-Support

     For example:

     # subscription-manager syspurpose service-level --set "Standard"

     1. Optional: Before setting a value, see the available service-levels supported by the subscriptions for your organization:

        # subscription-manager syspurpose service-level --list

     2. Optional: Run the following command to unset the SLA:

        # subscription-manager syspurpose service-level --unset

  3. Run the following command to set the intended usage of the system:

     # subscription-manager syspurpose usage --set "VALUE"

     Replace VALUE with the usage that you want to assign:

     • Production
     • Disaster Recovery
     • Development/Test

     For example:

     # subscription-manager syspurpose usage --set "Production"

     1. Optional: Before setting a value, see the available usages supported by the subscriptions for your organization:

        # subscription-manager syspurpose usage --list

     2. Optional: Run the following command to unset the usage:

        # subscription-manager syspurpose usage --unset

  4. Run the following command to show the current system purpose properties:

     # subscription-manager syspurpose --show

     1. Optional: For more detailed syntax information run the following command to access the subscription-manager man page and browse to the SYSPURPOSE OPTIONS:

        # man subscription-manager

Verification steps

• To verify the system’s subscription status:

  # subscription-manager status
  +-------------------------------------------+
     System Status Details
  +-------------------------------------------+
  Overall Status: Current
  
  System Purpose Status: Matched

• An overall status Current means that all of the installed products are covered by the subscription(s) attached and entitlements to access their content set repositories has been granted.
• A system purpose status Matched means that all of the system purpose attributes (role, usage, service-level) that were set on the system are satisfied by the subscription(s) attached.
• When the status information is not ideal, additional information is displayed to help the system administrator decide what corrections to make to the attached subscriptions to cover the installed products and intended system purpose.

Prerequisites

• You have completed the graphical installation according to the recommended workflow described in Installing RHEL using an ISO image from the Customer Portal.
