running, running and running while waiting for that magic command: Z EOD
Thats one magic system, not subsystem. ;-D
and perhaps if needed also that V XCF,... and reply after that.

No, Z EOD closes some logs etc., but z/OS still keeps on running.

Sure - it stops the I/O and resets the state of just about everything.

My point is that issuing an I/O reset (which is included in a system
reset) while a system may be doing I/O is a very bad idea, because it
can lead to data corruption, since the DASD record being written is
padded with zeros to replace the missing data from the channel.

On my sandbox lpar, I do
1) $PJES2,ABEND and reply END
2) V GRS(TEST),Q
3) if any other systems in grs... V GRS(TEST),P and reply YES
4) go to HMC, do SYSTEM RESET CLEAR
and it is really STOPPED.
One would bring a production system down more gracefully, of course, but
SYSTEM RESET CLEAR at
