Result
When restoring the CDR link, it is necessary to execute maintenance test on different objects that comprise the CDR link. It is recommended that you busyout the CDR link before trying to restore the link. When the CDR Link is busied out, then every CDR Link maintenance action is deactivated, and interference to tests of other MOs is prevented.
