There is a recent APAR (OH49573) that addresses an issue with SDSF being 
started before CMF and it should mean that you should not have to restart 
SDSF/SDSFAUX in order for subsequent availability to be recognised.

RMF returns 79-1 records even when its address space is down, so the SDSF DA 
panel should be fully populated. Other SDSF panels that rely on RMF like DEV 
and PAG however do require RMF availability.

Note that should you need to restart SDSF data collection, you can do so 
without stopping the main SDSF server by using "F SDSF,P AUX" followed by "F 
SDSF,S AUX". There is normally no requirement to stop the SDSF main server 
after IPL.

Sorry I am late to the game with this one. First time I've had a breather to 
look
at IBM-MAIN all of February.

I suggest stopping / starting SDSF (which will stop/start SDSFAUX also) and 
that may
resolve the problem. I ran into similar issues with both RMF and CMF when 
working
on z/OS 2.5. The best indicator of this problem is to do "DA OJOB" and if you 
see
STCs, then recycling SDSF will resolve it. If you have to recycle CMF or RMF for
any reason, you'll likely run into the same thing again and have to recycle SDSF
also.

Change your automation to not start SDSF until after CMF tasks or RMF is started
at IPL time. Making CMF/RMF a pre-req of SDSF should also remind someone
to recycle SDSF even if CMF/RMF is "forced" recycled without SDSF.

Regards,

Mark
