One sets up a new or one of the existing /etc/yum.repos.d/*.repo files to look at the locally mounted CD drive. I would copy "sl7.repo" to "sl7-local.repo", and reset the repository names to "sl7-local" and the like, and set their URLs to point to "file:///mountpoint/7.version/x86_64/os" and similar URLs. I've done just this sort of thing, successfully for internal SL, CentOS, and RHEL mirrors.
