disabling the conn test on a per host basis

I have a set of hosts that are not availabled via the conn test. I
attempted to disable the conn test for each by adding noconn after #
in the bb-hots file. However, the conn test column still shows up and
the conn test shows a red status until eventually the status changes
to purple. Am I missing something with the steps to disable a conn
test for a host?

Thanks
