From reading of adventures with cache batteries, I recall seeingsomewhere that cache didn't necessarily get flushed on power down.
Is there a document proving this?
if you would do a PWRDWNSYS *CNTRLD 30,
how do you know that 30 seconds are enough time to flush the cache?
I would think something as important as this, there would be some parm
on PWRDWNSYS to flush the cache...
I understood the *CNTRLD to be for those times you do not wait for the
"SYSTEM IN RESTRICTED STATE" message on the ENDSBS *ALL command. That is
what the help makes it sound as well...

I would have to agree with what the consultant said. When working with disk you should always end the system controlled because it does flush the cache in the disk controller.--
