Ed,
The z/OS 1.6 CONFIG command documentation states that as well. However, both
the HMC 2.9.1 Operations and z/9EC SE Operations guides state that this does
not happen. I would continue to use CF ONLINE/OFFLINE
>From HMC 2.9.1 Operations Guide
"You can use the Hardware Management Console workplace to configure channel paths on
and off. However, operating systems will not be notified when you use the workplace to
configure channel paths on or off. For example, if you configure off a channel path, the
operating system running in any image that owns or shared the channel path is not
notified, and the next operation from the operating system to the channel path causes an
error. It is recommended you use operating system facilities rather than the Hardware
Management Console workplace, whenever possible, to configure channel paths on and
off."

Hope this clears things up.
Clear as mud. Conflicting statements. It sounds as if Brian Peterson's
speculation is correct. Specifically, some hardware/software handshake
functionality, that got backed out because it never really worked, was
prematurely documented in z/OS MVS System Commands. I suppose an RCF is
in order here.
The last time I saw something similar was with the SET TIMEZONE command.
(It was documented for z/OS 1.6, but didn't work until z/OS 1.7.) Only
this case is much worse. The operating system book describes hardware
functionality that flat out doesn't exist in the referenced processor
generation or the next! Will such functionality *ever* exist??
