No.  All that does is tell the hw which IOCDS "slot" to use at POR/IML

Take David's advice and read the "I/O Configuration" manual.  It contains

information about "manual" dynamic I/O config as well as HCD.  Note that 
the
z/VM 6.1 version of the book has had some significant updates.  Use that 
one.
