Issue

I'm trying to activate my Red Hat Linux machines with my subscription licences, but when I enter the command subscription-manager attach --pool=<XXXX>, I get the message:
```
Ignore attachment request. Subscription linking is disabled for the ‘12345678’ organisation because simple content access (SCA) is enabled.
```
How can I find out if my Redhat machine is activated with the license or not?

A Red Hat subscription provides unlimited access to our knowledgebase, tools, and much more.
