Red Hat Subscription Management overview

RHSM is the primary subscription management service provided by Red Hat and is the replacement for Red Hat Network Classic (RHN). RHSM is an end-to-end solution with status, inventory, organization, and reporting for Red Hat subscriptions via a hosted web-interface accessed from the Red Hat Customer Portal.

Although subscription management was primarily established on Red Hat Enterprise Linux, all Red Hat products are expected to be integrated with Red Hat Subscription Management. Red Hat Subscription Services are available for systems running Red Hat Enterprise Linux 5 (5.7 or later), 6 (6.1 or later) and 7.

Systems running RHEL 5 (5.7+) and 6 (6.1+) can subscribe to both RHN and RHSM. However, RHEL 7 systems can only subscribe to RHSM, unless using Red Hat Satellite 5.6 or above. The RHEL 7 channels are only available when using Satellite 5.6 or above. A direct consequence of this is that the RHEL 7 channels are not available in RHN which means that the the redhat_import tool configured to import from RHN cannot be used to import RHEL 7 content into the SA Library. The RHEL 7 channels are only available when using Satellite 5.6 or above. The redhat_import tool configured to import from RHN can only be used to import RHEL 7 content when used behind a Satellite 5.6 or Satellite 5.7.

More details about the specific supported versions can be found in the SA Support and Compatibility Matrix associated with your SA version.
