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." >From the z/9 SE Operations Guide: "You can use the support element 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 shares the channel path is not notified, and the next operation from the operating system to the channel path will cause an error. It is recommended you use operating system facilities rather than the support element workplace, whenever possible, to configure channel paths on and off." Hope this clears things up.
