VM/370 IPL request


 

Hello,
could you please explain to a person who knows very little about VM/CMS (that's me, the person!) what in VM/370 CE allows to bypass the change TOD request and the start type warm|ckpt|... ?
If it's too long to write here could you direct me to the right documentation?
Thanks
?

Marco,
It will be a CP fix, but I can't figure out which..

Could it be DMKCPI HRC036DK on MAINT minidisk 094?

Would that be, in a world of turkeys, a user mod? That would explain why I have not been able to find any mention of it in the manuals available on bitsaver.

If DMKCPI HRC036DK is the guilty party, then yes it is a modification from the Hercules community, like (I believe) everything on MAINT minidisk 094.

That looks correct.
Just for info log on to maint, do "VMSETUP CP" and there is a MEMO file for each mod on the "F" disk.

NO!
You are the culprit, without your video about RCSC I would not have put my nose in things I should never have touched.

Marco,

yes, logon to maint, do "VMSETUP CP' and "HRCMODS MEMO" lists the user mods for CP. There is a <modnumber> MEMO file for each mod on that disk.
"VMSETUP CMS" will get the "HRCMODS MEMO" file accessed. For some reason the CMS memo files are "MEMO <modnumber> F

.. actually the CMS way makes more sense

I believe your problem is related to how you do (or don't) shut down VM. If the warm start data is not saved, then you will get both a TOD and SPOOL question at the next IPL.
?
If you have an OPERATOR console open on say 010, enter the command "CP SHUTDOWN" and press enter.

If you don't, then look for your Hercules console, and enter "/CP SHUTDOWN" and press enter.
?
In either case enter the following in the Hercules console. This isn't absolutely necessary, but the MVS guys do it and it doesn't hurt to do it for VM.
?
STOPALL
SYSCLEAR
QUIT
?
Let me know if this is unclear, or doesn't help.

You may want to read MAINT MEMO on MAINT 5E5.

You may also want to read Melinda Varian's "What Mother Never Told You About VM Service (1983)."

The whole story:
I watched Prof. Ferland's video, with difficulty because I'm better at reading than watching a movie.
My goal was to define three lines, one towards TK4-, the second towards HMVS (Jay Moseley's system) and the last one for an RJE station.
So I started looking in the documentation and I saw in the sysgen manual that normally in the first phases of the IPL it asked for the time and type of start. Something I had never seen with the VM/370 CE.
As I said, I couldn't find a refernce in the online manuals and I had to ask.
I always use SHUTDOWN and every reboot of VM was automatically done without any request.

Hello,

How do the above Hercules commands compare to the EXIT command after doing a CP SHUTDOWN?

Thank you,

No need on VM. "CP Shutdown" is fine.
