3. Attaching and Removing Subscriptions
Assigning a subscription to a system gives the system the ability to install and update any Red Hat product in that subscription. A subscription is a list of all of the products, in all variations, that were purchased at one time, and it defines both the products and the number of times that subscription can be used. When one of those licenses is associated with a system, that subscription is attached to the system.
3.1. Attaching and Removing Subscriptions through the UI
3.1.1. Attaching a Subscription
- Launch Subscription Manager. For example:
[root@server ~]# subscription-manager-gui
- Open the All Available Subscriptions tab.
- Optionally, set the date range and click the button to set the filters to use to search for available subscriptions.
Subscriptions can be filtered by their active date and by their name. The checkboxes provide more fine-grained filtering:- match my system shows only subscriptions which match the system architecture.
- match my installed products shows subscriptions which work with currently installed products on the system.
- have no overlap with existing subscriptions excludes subscriptions with duplicate products. If a subscription is already attached to the system for a specific product or if multiple subscriptions supply the same product, then the subscription service filters those subscriptions and shows only the best fit.
