In my case it was that simple.  There were no active links.  I thought
there was more to do than just update the CONFIG file and detach from
system.  Guess not.  Thanks to all.

Thank you,

Scott

Maybe even easier than Brian suggested, depending on your purpose. If
all you want to do is to prevent CP from complaining about the disk not
being present during start-up, simply removing the disk from the list
should suffice. If you want to remove the disk from the system, you will
need to DETACH it from SYSTEM. If it is actively being used, it may be
difficult to find a time when there are no users linked to it. In that
case, you can DRAIN the device using the LINK option to prevent any new
links to it.
