  • Some systems may not have internet connectivity, but administrators still want to attach and track the subscriptions for that system. This can be done by manually registering the system, rather than depending on Subscription-Manager to perform the registration. This has two major steps, first to create an entry on the subscriptions service and then to configure the system :-

    • Open the Subscriptions tab in the Customer Portal, and select the Overview item under the Subscription Management menu area.
    • In the Usage area on the right, click the Subscription Management link.
    • In the Units area on the left, click the Register link.
    • Fill in the information for the new system.
The name for the entry, which is normally the hostname(for example - mybox2).
The system type, physical or virtual.
The architecture, which is used to determine compatible subscriptions.
The number of sockets, either the number of physical sockets or, for virtual machines, the number of CPUs. Some subscriptions cover to a certain number of sockets, and multiple subscriptions may be required to cover larger systems. 
  • Once the system is created, attach the appropriate subscriptions to that system.

    • Open the Attached Subscriptions tab.
    • Click the Attach a subscription link.
  • This way, you can attach subscriptions to the systems that have Red Hat Enterprise Linux version lower than Red Hat Enterprise Linux 5.7 or Red Hat Enterprise Linux 6.0 version to keep the track of subscriptions.

  • In some specific subscriptions (like "Red Hat Enterprise Linux for Virtual Datacenters"), this way is not able to use with the newly registered virtual system.

This does not talk about taking the additional steps of downloading the subscription .pem, burning it to CD-ROM, then using Subscription Manager to import the .pem into the host.

However, how does one do a similar thing with the .pem file that represents the host's registration? That .pem is an identity file, which is different from the subscription .pem file.
