At one point, we started to recommend this in The Virtualization

is much more valuable on z than disk.

I couldn't find the reverse video setting in MS Paint under Windows 7.
I started looking into the various freeware/shareware tools mentioned.
But I did have Snag-It. Yes it
Hello lists,
Back in June, I was blogging on the ITSO Residency to update The
Virtualization Cookbook. It's now more than two months later and we
still don't have a first draft :(
But hopefully it is now a matter of more days not months.
One item (that may seem inconsequential) is that we have

There is a more recent Virtualization Cookbook which describes RHEL 6.2.
It is a whitebook, not a redbook. Start at

Raymond,
What are the correct disk sizes for 191 and 192 for future growth when
they are formatted for LNXMAINT?
The 191 is just used locally on LNXMAINT so it can have a different
PROFILE EXEC - so 20 cylinders is more than enough.
We used to recommend 300 cylinders for the 192 disk which
Hello lists,
Mz 2.18 was uploaded to https://sourceforge.net/projects/managing-z
It is a minor release:
-) Add link from CP level to z/VM component levels for each version
-) Fix bug in mzvmhealth where 0 values were showing blanks not zeros
I also updated the files on sourceforge so only the
I intend to write up something if I can ever get it to work the same
way twice without futzing with it.

Maybe Mike M. can make us a cookbook :)
Doubtful :(( I'm in over my head trying to wrap up the latest version.

David,
1) a section on setting up the CMS SSL server to provide secure
management traffic transport.
2) a section on enabling SMAPI and the use of smaclient to manipulate
the images.
We had talked about the SSL server early. Apparently this is a
complicated install. Given the quantity of
Chris,
./smaclient smiucv will compile it and place it in the current
directory.
Yes, that worked! Thanks.
For some reason, I thought that process was done auto-magically.

Hello lists,
Thought I'd blog a bit more on The Virtualization Cookbook residency.
The first week we got a z/VM ESP system installed in a 2-node SSI cluster.
We defined an IDENTITY (aka an MCVM) named LNXADMIN with the system on one
member being focused on RHEL and the other on SLES (addressing
John,
you might include a (sub)chapter on setting up a Hipersockets network.
Thanks for the input - we will add it to the (wish) list...

Chris,
Thanks for the info - I was able to recreate and see the issue.
There is Scott's reply.
Perhaps Alan will also chime in.
And somehow, we will address this in the updated Cookbook.

Hello lists (cross-posted to linux-390 and IBMVM),
Here's a bit of a blog on an IBM Redbooks residency that started yesterday
in Poughkeepsie, NY: we got funding this year to update The
Virtualization Cookbook, this time as an official IBM Redbooks
publication. We have a great team of five

Alex,
That is not what I see at my end.
Wait, what?
You have two RHELs and they agree with my RHEL - the value for Cached in
/proc/meminfo is also shown in free. It's SLES's free that seems to
add the Cached and SReclaimable values (and as Rob points out,
possibly also SwapCached).

I'm hacking around with CPU utilization numbers from /proc/stat with this
little script:
# cat getticks
#!/bin/bash
echo getting one set of data
statOut1=`egrep '^cpu ' /proc/stat`
echo sleeping 5 seconds and getting another set of data
sleep 5
statOut2=`egrep '^cpu ' /proc/stat`
James, Emmett,
Thanks for the replies. Good to know that an older and a new RHEL seem to
come up with the right answer (I assume you both have 2 vCPUs).
Just to be sure, I tried again on my reference system, and got similar
results:
# cat /etc/redhat-release
Red Hat Enterprise Linux Server
Mark,
Thanks for the reply. So, it would seem more correct to add in the
other two components. Interesting ...
I guess that explains why on one system I'm looking at apples and on the
other at oranges :))

Hello list,
Aha moment - a while back I reported that vmstat 1 2 was core dumping on
RHEL 6.3. I got a reply this is a known issue and that there is a fix.
This must be the same issue (without a proper tick count, the code might
be trying to divide by 0). Another mystery solved.
I think it's
