[hercules-390] rasberry-pi as a z114

[Gregg Levine [e-mail] [hercules-390]]

Hello!
Martin Truebner would you do us a favor and share how you managed to
convince a regular Raspberry Pi that it was a Z114 system? (And which
OS it runs via Hercules of course.)

I saw that mentioned on a thread concerning Hercules Console commands
via command line, and figured I'd open a new thread to ask this one.

I have a batch of them some doing nothing here, and am interested in
confusing one of them to do that. As for boxing it in Lego that's a
bigger stretch.

Gregg,

if you watched the video for at least 15 seconds you have a link to a
PDF that has more on hardware for the "system"

here it is for the lazy ones: http://pi-sysprog.de/z114.pdf

IBM had a feature in the "IBM Systems Magazine" in January 2015 -
which has even more about it/me.

Here is a link

http://ibmsystemsmag.com/mainframe/stoprun/stop-run/martin-trubner/

Your question what it runs: Debian then Herc then a very old DOS and
then CICS.

Why a very old DOS... I did try recent versions of CICS/TS. It took
forever to come up. Hence I experimented with older versions and I
am now running a 20 year old CICS (with an as old DOS) which comes up
within 5 minutes. Once it is up, it is very responsive.

For the fun of it I modified a DITTO version running on new CICS
only to run on that old CICS (it has a nice User-interface which even
z/OS-people can use). The hotspot (on my mobile) can accommodate 5
users- so the most I had (on conventions like the WAVV or SHARE where
enough mainframers are around) at the same time on the machine is 5
users- we never had any response time problems.

on this stuff..

Well, the last two guys we helped getting their used mainframe running
got hired by IBM. What parts do you need and what do you need
configured? IBM-Main can be a big help too.

The only hardware that I'm missing is DASD.

Can you use some kind of SAN?

But my biggest limitation here
is time. So I guess what I'm really looking for is people to physically show up
and hack on stuff.

Does it count as work? Do I need an employment Visa? Mind you given the time its taken to get the P390 going perhaps I am not an ideal person....

I wonder how much work it would take to extend the LinuxIO (a.k.a. LIO)
SCSI Target to support FICON.

I believe that was part of the initial port. It should install on
ECKD DASD just fine. Linux runs under VM and Hercules.

I think you and he are talking about two very different things.
"Target mode" allows a computer running Linux to be a SCSI target, i.e.
a disk drive. FICON is FibreChannel, which in turn is serialized SCSI
with a bunch of very nice housekeeping and traffic management features
added.

I assume IBM added their own commands atop the FibreChannel layer that
would have to be supported in target mode. But if someone were to do
that, a Linux computer (say, an embedded one within a large disk array)
would be able to be a FICON DASD array.

I'm not talking about just a Linux GUI. I mean an entire Linux
system, and ONLY a Linux system, on just about any architecture. No
RS/6000s (like the Sharks have under the hood) with special and
expensive hardware, no proprietary software or firmware, no IBM license
keys, no "this is broken, call support" BS, etc. You have auditable
source code for everything, and are not beholden to IBM at absurd price
tags to get something to answer to a mainframe's FICON port.

Here is a PDF with a list of manuals. Looks like it dates from the
start of ESCON, so some of those manuals might have the information
you need. Hopefully there are similar FICON manuals out there. I
know EMC's hardware seem to be a few generations back from the
mainframe software.

I believe that was part of the initial port. It should install on ECKD
DASD just fine. Linux runs under VM and Hercules.

I'm talking about the other way around. Having Linux's LIO SCSI Targets
be the FICON attached DASD for a mainframe.

I'm specifically thinking about the people that own a mainframe but
don't have any DASD for it. People like Connor, and Jim, et al, who
want the ability to do something, anything at all that requires ECKD
DASD. (Insert applicable unsupported / non-production / etc disclaimers
here.)

I.e. I have a CEC and I need FICON DASD. It would be really nice if
Linux LIO SCSI Targets could be said FICON DASD.

For some reason my reply was chopped off
Trying it again

What you need to do this is a fiber channel card that gets the ficon packets and a Linux driver that processes the ficon packets. I worked on such a beast when I worked at StorageTek on the virtual tape product. The ficon spec is an ansi standard downloadable from t11.org. I am not at home to find it but look for SB3 specification. We used both Emulex and Qlogic cards. The documentation needed to implement was provided under a NDA agreement and not publicly available. This was in the 2003-2006 timeframe. At one time emulex had a open source driver that may expose how to talk to the card but it’s been a while since I looked at it.

being discarded, is going to be expensive.

...which is why we don't have one. ;) I've got a lot of money coming
in, but I also have a lot of money going out...I won't have enough
disposable cash to drop on a FICON array anytime soon.

That said, we do have to Shark arrays here, but they lack drives, and
apparently they have a very large minimum number of drives to bring them
up. I'm also concerned about them possibly requiring drives with IBM
firmware, but I'm not sure about that. We really have no intention of
running them; they're just too large.

-Dave

[Mike Schwab [e-mail] [hercules-390]]

I believe you have to install 16 drives in the first two racks. Then
you can set up a Raid 5 for the capacity of 6 drives over 7 volumes
and the 8th is a hot spare. Then you split the space into individual
drives.
