Section Number and Name:
3.5.3. Removing the Previous Version of the Satellite Tools Repository

Describe the issue:
Information is irrelevant. The name of the repository is wrong.

From Satellite 6.11, the tools repository is replaced by the below repos:

For RHEL-6
rhel-6-server-els-satellite-client-6-rpms

For RHEL-7
rhel-7-server-satellite-client-6-rpms

For RHEL-9
satellite-client-6-for-rhel-8-x86_64-rpms

For RHEL-9
satellite-client-6-for-rhel-9-x86_64-rpms

The client repositories are same for Satellite v6.11 and v6.12. Hence, no need to disable the repositories.

Suggestions for improvement:

Additional information:
No need to disable the client(satellite-tools) repository.
