Yes, I've been using the above for quite few years. However I remember 
times, when "F BPXOINIT" was the only option.
BTW: AFAIK "F OMVS,SHUTDOWN" do (close) more things than "F BPXOINIT", 
and it is required in order to shutdown system.


Regarding HALT - obviously I forgot Z EOD. So, we have two HALT 
commands, one for VTAM, second for EOD (TCAM is history).

The only other place I've seen HALT used is when we do a "Z EOD".
It's one of the legacy commands our operators use during the weekly
IPL process.  As far as I know, all that really does is stop SMF
recording.  It doesn't seem to hurt anything to leave it in the
process but it doesn't seem to have a benefit either.  Anyone else
know why we should keep doing this?




HALT was also used to shutdown TCAM  "Z TP,option" IIRC.
EOD, TCAM, and VTAM are the only things I know of that use
the HALT command.

Z EOD causes SMF TYPE19 (DIRECT ACCESS VOLUME) records to be
gathered (if you record them), and then flushes SMF and
SYSLOG buffers (probably EREP as well).

If the buffers are not flushed, any data in them may be lost
when you IPL.

  It checked the old code libraries, and it looks like the CONFIG
command came into existence in SP2.1.9 (first release of MVS/XA).
My recollection is that CONFIG took over (from VARY) those resources
(storage , CPs, and channels) involved in the physical partitioning
of a 3084 processor under operating system control.  The
physical partitioning of prior MP machines (158MP, 168MP, 3033MP)
was done by VARYing the appropriate channels, CPUs, and storage
offline, and then going to the processor console to initiate the 
physical partitioning.  On the 3084 under MVS/XA, the 
physical partitioning could be initiated from MVS via the 
CONFIG SIDE command.

In both cases, it looks as if the z/OS UNIX folks did not want to
"bother" the people in charge of CONSOLE to implement new z/OS commands.
Look at the LIBRARY command. Very strange. It converts the LIBRARY
command into a MODIFY OAM command. If somebody really wanted to, they
could likely implement a "UNIX" command (say via CA-OPS/MVS command
rule) which would then issue the proper MODIFY command(s). Or the z/OS
UNIX folks could have used the CPF function in z/OS to make a "command
prefix", perhaps specified in the BPXPRMnn member, to issue OMVS type
commands. That would have been useful!

CONFIG seems to be more related to things you could do with the 
hardware interface (HMC) - or commands that "talk" to the hardware.
VARY is more on a device / logical / OS level.   

I guess I haven't been around long enough to remember VARY for
storage, channels, and CPs or didn't do them under MVS/SP 1.3 which
is when I got my start with MVS.

 John,

Somehow I have it stuck in my mind that the VARY command just works at
the OS level, varying devices online or offline to z/OS but nothing
else.  Using the CONFIG command actually changed the configuration in
the I/O subsystem or other areas that are closer to the hardware.  I'm
probably wrong with this but that's what I remember.
