Guest IPL under z/VM causes FRE016 Hard Abend

[Fish-Git]

Peter: may we see your 1st level and 2nd level directory statements for your z/OS guest please, as well as your 1st level directory statements for your 2nd level z/VM too?

It would also be nice to see your Hercules configuration file (and log file!) too please.

Also, how did you create your 2nd level z/VM's dasds? Are they simply copies of your 1st level z/VM's dasds?

Basically, I need a little bit more information on how to reproduce your problem. I will of course attempt to reproduce it myself in my own way, but in case I can't, it would be nice to document precisely how you are able to reproduce the problem on your system.

Thanks!

I've replied to Fish off-list.

FYI:

I finally managed to set things up to try IPLing z/OS under 2nd level z/VM, and it failed while I wasn't looking, so I don't know whether it was a "FRE016 Hard Abend" or not.  :(

I've been incredibly busy with looking into many other things besides this issue, so I have not had time to try it again yet. But I definitely will.

I will note however, that the abend, whatever it was, occurred on the 2nd level z/VM, not the 1st level z/VM, so I'm not sure how to go about trying to capture and/or research that. My z/VM debugging skills are virtually non-existent.  :(

What's worse is, if this is indeed a Hercules bug (and I have no doubt that it is), I too, just like Peter, am just as perplexed as to how to go about trying to debug/capture it!! Especially given that it seems to only happen on the second level z/VM system and not the first level!  :`(

Any ideas anyone? I think researching this issue might be out of my league.  :(

My test setups no longer exhibit this problem. That is not to say that I no longer experience any Hercules problems like a crash now and then without even leaving any message whatsoever in the Hercules log. But this perfectly reproducible FRE016 from August last year no longer occurs. Actually at times z/VM (7.2 or 7.3) with z/OS 2.5 in a VM under it, runs pretty stable for hours or even days.

I therefor propose to close this issue. When I have had the time to document experienced remaining Hercules problems, I'll open a fresh issue for it.

Thanks,

Sounds good to me! Closing!
