The DCSS that was specified with the monreader.mondcss kernel parameter or
with the mondcss module parameter cannot be a *MONITOR DCSS because it is
not of type SC.
User response
Confirm that you are using the name of the DCSS that has been configured as
the *MONITOR DCSS on the z/VM hypervisor. If the default name, MONDCSS, is
used, omit the monreader.mondcss or mondcss parameter.
