15.3.2. Attaching and Removing Subscriptions through the Command Line

15.3.2.1. Attaching Subscriptions

Attaching subscriptions to a system requires specifying the individual product or subscription to attach, using the --pool option.
[root@server1 ~]# subscription-manager subscribe --pool=XYZ01234567
The options for the subscribe command are listed in Table 15.3, “subscribe Options”.
The ID of the subscription pool for the purchased product must be specified. The pool ID is listed with the product subscription information, which is available from running the list command:
[root@server1 ~]# subscription-manager list --available

+-------------------------------------------+
    Available Subscriptions
+-------------------------------------------+
ProductName:            RHEL for Physical Servers
ProductId:              MKT-rhel-server
PoolId:                 ff8080812bc382e3012bc3845ca000cb
Quantity:               10
Expires:                2011-09-20
Alternatively,the best-fitting subscriptions, as identified by the subscription service, can be attached to the system by using the --auto option (which is analogous to the --autosubscribe option with the register command).
[root@server1 ~]# subscription-manager subscribe --auto
