Nope, actually a P/390 evolution. Think P/390 with a emulator for the
processor instead of a hardware processor.
it is purely an IBM development (although there are some similarities with
FLEX-ES).
As to cost, it depends... For ISVs, it is generally a little less than
FLEX-ES systems. For RD&T

Hi, Mark.
What does IPL-ing CMS first in a Linux guest to do some setup housework,
building a swap VDSIK in this case, have to do with LGR? Once Linux is
up and running in the guest, what would prevent it from being moved? I
guess I don't understand your question?

There is a zPDT software licenses that runs in a notebook or intel. It´s

All,
I'm developing some internal education on System z for people that don't have
that background. I would like to include a section on tools that a lot of
customers use that they get from somewhere other than SUSE. The first example
that comes to mind is

It looks like something is not supported :
/dev/mapper/20017380062aa0048_part1 on /mnt/thin_test_btrfs type btrfs (rw)
d2ora000:/var/log # fstrim /mnt/thin_test_xfs/
I dumped the contents of the swap spaces, at 100K 512 byte sectors and at 200K
512 byte sectors, using both SWAPGEN and mkswap to create them. The
differences in output is interesting, but I can't say I know what they mean.

Hi, Ron.
I believe P390 boxes are still alive and kicking at a number of small
mainframe sites around the world..
IBM now offers a small system just for development work called the
zPDT...I think the PDT stands for Personal Development Tool. You can
read all about it here:

The Cloud Computing Cookbook,

create VDISKs, IPL Linux and still do LGRs. The CMS disks are simply
detached when Linux star
Thanks for the suggestion, Mark. To partition or not to partition; that
is the question;-)
I also have another change that would remove the requirement for having
the RXDASD package available as well. If we do need to make a change to
SWAPGEN, I'll see about adding that in as well.

That used to be the case Steve, but not any more. zPDT (the package you are
thinking of) is now available to any company with a System z mainframe but
it is limited to development and testing only. (Thus the name "Rational
Develop & Test", RD&T).
Licensing for RD&T is somewhat complex (as for al

This looks like a FLEX/ES evolution. I don't even want to think about

If modifications become necessary (for whatever reason), it might be a good

We do #2 and LGR works great. Like this:
/* if disconnected, then just start linux */
if disco == 'DISCONNECTED' then do
queue 'CP DET 190'
queue 'CP DET 19E'
To my knowledge there is no product currently marketed by IBM to
enterprises, etc.
IBM does have a product that is available only to ISV. I think you have
to make a case for the box initially and then it's renewed on an annual
basis.

Hi, Mike.
Yes, Rich Smrcina has reported this problem as well. To the best of my
knowledge, the 2008-04-16 version of SWAPGEN is the latest. If the fix
for this problem has already been discovered, please let me know so I
can add it into the "official" SWAPGEN distribution code at SNA.
Thanks.

I was being stupid, overlooking the fact that I could DETACH all the CMS
minidisks in my EXEC. I work on to many OSes at once. I can't keep
straight what I am working on 1 min to the next. It's like starting to
write code in one language and mid-way through start writing in a different
language,
I've seen this on SLES11-SP2 too... And I saw some other issues with
SP2, like not arp-ing when bringing a interface online, and hanging
the ssh terminal on exit...
I've solved the problem with a script, running after all services. The
script does the mkswap and swapon on them. And works.

Thanks, Marcy - that was the kick in the head i needed to recall that was

Absolutely! And it is a descendent of the P390.
Check out zPDT (System z Personal Development tool: for ISVs developing
software to sell) and RD&T (Rational Develop and Test: for "in-house"
developers who want to get off the primary/production System z. )

That doesn't sound right to me. After the Linux guest IPLs itself (
We've always done it in /etc/init.d/boot.local. That way we are safe from
whatever changes Linux might make...
Like this
/sbin/mkswap /dev/disk/by-path/ccw-0.0.ff00-part1
/sbin/mkswap /dev/disk/by-path/ccw-0.0.ff01-part1
/sbin/mkswap /dev/disk/by-path/ccw-0.0.ff02-part1
/sbin/mkswap /dev/disk/
Thanks, Alan. I guess for simplicities sake just detaching all the
minidisks associated with CMS just before IPLing the Liunx system is the
easiest solution.
