Description of problem:

Using rhui-manager I am trying to sync a CDS cluster and not seeing the CDS cluster displayed from the "sl" menu option.

Select one or more CDS clusters to schedule to be synchronized before its scheduled time.
The sync will happen as soon as possible depending on other tasks that may be executing
in the RHUI.  Only CDS clusters that currently do not have a CDS instance sychronizing are displayed.
