Not been listening until now so pardon me if this is way off base but SMF 
73 might help here. (I, for one, would detect the change this way.)

Fields SMF73TNM onwards would be useful.

1. HCD vs IODF. Actually both names are not 100% accurate. There is no 
*simple* and accurate name, it is I/O configuration. HCD is an 
application to create such configuration, IODF is dataset which contains 
the configuration, but there is also IOCDS, and active configuration in 
MVS (let's focus on this OS) and HSA.

2. D IOS,CONFIG shows current configuration (IODF name) for both HSA and 
MVS, but it doesn't show whether the config was activated after IPL. 
Even case where IODF HSA <> IODF MVS does not mean there was an 
activate, because system could be IPLed with non-matching IODF (which in 
turn disallow dynamic changes).

3. AFAIK Mark's IPLINFO (great tool BTW, thank you Mark!) does not show 
whether dynamic change took place.



BTW: What's the goal? IMHO there are some other methods to get such 
information. Not to mention dynamic activate should be strictly 
controlled and performed only by persons who really know what they do.
