Re: Open Vswitch and SLES12 KVM

2017-12-15 Thread Tito Garrido

Hi Folks!

The place that Robert pointed it is correct, but to update it we use a
script called qeth_configure (I guess it would be similar to chzdev but for
SuSE and network only)

So the answer was:

qeth_configure -l -o "bridge_role=primary" 1

Thank you!

Tito

Open Vswitch and SLES12 KVM

2017-12-11 Thread Tito Garrido

Hi Folks,

What is the recommended setup for open vswitch on SLES 12 on z?

I can see:
https://www.suse.com/documentation/sles-12/book_sle_admin/data/sec_ovs.html

But it says nothing about BRIDGEPORT.

Where should I put OPTIONS="layer2=1 bridge_role=primary

Is "OPTIONS" a recognized option on SuSE?

Regards,

Tito

SuSE Cloud 6 + z/VM - Any adventurer?

2016-04-20 Thread Tito Garrido

Hi Folks,

I have been checking SuSE Cloud 6 capabilities in my "hybrid environment"
(zPDT + KVMx86) but I got stuck on Neutron + Nova config...

The neutron recipe runs fine, even though I can't see any connection tempt
from XCAT /var/log/message...

When I try to deply Nova I get the following message:










*root@d52-54-00-a1-98-8b:~ # cat /var/chef/cache/chef-stacktrace.out
Generated at 2016-04-20 11:09:12 -0300Chef::Mixin::Template::TemplateError:
Chef::Mixin::Template::TemplateError (undefined method `[]' for
nil:NilClass) on line #57: 55: <%end -%> 56:  57: [<%=
@svm[:zvm_xcat_mgt_vswitch] %>] 58:  59: # (StrOpt ) rdev_list for each
vswitch's uplink real device(s), seperated by ','.*

The error seems to be related to rdev_list for physnet... I have tried
comma separated and even blank values.

I have been following the deployment documentation (
https://www.suse.com/documentation/suse-openstack-cloud-6/book_cloud_deploy/data/cha_depl_ostack.html)
but it doesn't provide much regarding z/VM...

Anybody playing with SuSE Cloud 6? :)

Hi Dave,

My parmfile is clear... this is what I get during the installation IPL:
The Linux kernel requires more recent processor hardware
HCPGIR450W CP entered; disabled wait PSW 0002 8000  0BAD


I am running the latest version of zPDT so it should be a z13.

When I tried to install it on a zPDT it complained about my processor (says
that it is not supported), is it an zPDT issue or ubuntu is not recognizing
the machine type 1090?

zKVM on zpdt

2015-10-02 Thread Tito Garrido

Hi Folks,

  I have already asked this question on z1090 mail list but it may be
interesting for other people here that would like to try zKVM and also you
may know the answer :)


I am trying to install zKVM on zpdt but it is not able to run dasdfmt
during the installation:


2015-10-02 02:13:15,704 - program - INFO - Running... /sbin/dasdfmt -y -d
cdl -b 4096 /dev/dasda
2015-10-02 02:13:15,734 - program - INFO - /sbin/dasdfmt: (invalidate first
track) IOCTL BIODASDFMT failed. (Input/output error)

Any clue?

I have already tried to run CPFMTXA on a z/VM instance and run the
installation again but no success...

Tito

Automation for RACF SMF

Hey Folks,

I was reading a presentation from Bruce about RACF and there is a
recommendation to use an automation for RACF SMF maintanance...

http://www-03.ibm.com/support/techdocs/atsmastr.nsf/5cb5ed706d254a8186256c71006d2e0a/d0cbdc851eb2d52986257b2e007d3d39/$FILE/RACFaudit_techdoc.pdf

Anybody has a functional example for a daily or week rotation of SMF data?

  Why not 4 LNXADMIN USERS or 1 relocating if needed...
 As Berthold mentioned, the Linux terminal server needs one Linux system per
 z/VM.  If you also use these servers as LDAP or DNS servers, you may want
 one to be primary and others secondary/tertiary. A couple of other
 solutions that fit this model well are global file system servers and zoom.

   I am supposing that we are creating LNXADMIN as a IUCV server for the 4

  IDENTITY users are able to logon to all the systems in the SSI cluster at
  the same time.  They also get their R/W minidisks from the SUBCONFIG
  instead of the USER section.  That means that those minidisks (a) don't
  have to be on shared DASD, and (b) are NOT PROTECTED from cross-system
  LINKs.  And *that* means that they can logon even if there is an issue
  with the SSI cluster communications.
 
  So the decision of whether to make a guest an IDENTITY or a USER is
  completely dependent on how you intend to use the guest and its
 resources.

LNXADMIN as IDENTITY

2015-07-09 Thread Tito Garrido

Hi Folks,

I am trying to understand why the cookbook (For SSI installation) creates
LNXADMIN as a IDENTITY guest. Is it because of the clone script?

Thanks,

Tito

 Greetings VM List!

 We recently moved a database from DB2 9.5 running on SLES10 SP4 to DB2
 10.5 (fix pack 5) running on SLES11 SP3, both under z/VM 6.2. We're having
 some issues with increased memory consumption and wondered if anybody else
 had noticed a similar trend. To give a little background the old guest ran
 wonderfully efficiently for a number of years with 2G of memory allocated
 to the guest. The new guest has been sized up through the testing period to
 8G and we're still having problems. The recommended mode for DB2's memory
 management is to run with its automatic memory management feature enabled.
 This seems, however, to just gobble up all the memory we can give it and
 has led to the guest freezing until we remove the load from the application
 running queries, at which time it becomes responsive again. Any advice on
 either OS configuration parameters (beyond what IBM recommends here:
 http://www-01.ibm.com/support/knowledgecenter/SSEPGG_10.5.0/com.ibm.db2.luw.qb.server.doc/doc/c0057140.html?cp=SSEPGG_10.5.0%2F2-0-1-2-2-0-10-1)
 to be aware of or DB2 configuration that might help us with this would be
 enormously appreciated.

  Subject: Fedora 21 for IBM System z release
 
  Hello everyone,
 
  Fedora 21 GA release for the IBM System z (s390x) is here. This time
  only 9 days after primary release. The difference against primary
  Fedora is smaller than it was in Fedora 20, but we are still missing
  packages related to nodejs (v8 engine not publicly ported to s390x)
  or golang (but work is being done on gcc-go, so this should change in
  the future) and most of ocaml modules (native port would be
  required). For details see
  http://fedora.danny.cz/s390/rebuild/koji-compare-f21.txt
 
  The links to the actual release are here:
 
  http://mirrors.fedoraproject.org/publiclist/Fedora/21/s390x/ or

 http://download.fedoraproject.org/pub/fedora-secondary/releases/21/Everything/s390x/os/
 
 
  Currently Fedora for s390x is available as the Server flavor (refer
  to http://fedoraproject.org/wiki/Fedora.next for more information).
  The first directory contains the installation tree as well as one DVD
  ISO with the complete release. There are plans on adding Cloud flavor
  in the future, but it depends on s390x support in several related
  projects. Everything as usual contains, well, everything. :)
 
  For general Fedora documentation please see
  http://docs.fedoraproject.org/
 
  and Fedora 21 common bugs are documented at
  http://fedoraproject.org/wiki/Common_F21_bugs

  state for future release, where and how the team can be reached and
  just anything else Fedora on IBM System z related can be found here:

 daily, weekly, monthly reports created for linux, z/vm, network all

 If you would like to talk more, or maybe talk to some of the hundreds of
 installations that run this, that can be arranged.

 Hello,

 We have several zLinuxes installed and been happy with the overall
 functionality especially now when we got the new IBM wave tool installed.
 However, Wave didn’t help is with the problem with the Linux level
 reporting we currently have. z/VM performance reporter gives us current
 overall status, but is not very helpful for longer period capacity trending
 at least from single Linux perspective. Our company’s standard Patrol
 agents show somewhat twisted and misleading information about Linux on z
 especially on CPU point of view and this cannot be modified.

 So…now I’m trying to find out which Linux tool could be used as a good
 base for this reporting requirement. Nmon seems to be the best candidate so
 far, haven’t tested SAR yet. Currently I get automated nmon reports from
 one of our zLinux servers and they generate nice graphs with nmon_analyzer
 Excel program. However, it’s not very convenient to manually create graphs
 every day on your laptop…especially when we get reports from several
 servers in the future.

 On AIX you can use nmon2rrd which uses rrdtool for conversion. Also there
 are some nmon2web scripts for AIX. For Linux you can get several nmon web
 page generators which are often based on rrdtool and you have also couple
 of viable SAR graph generating options. I have tried to find a good
 solution for zLinux but so far haven’t been able to fill this automated web
 page generation gap.

 To sum this up:
 - We need a performance reporting tool which can be fully automated via
 Linux scripting or similar for multiple zLinux instances. As there seems to
 be several freeware possibilities, we would prefer them.
 - Currently I have created a routine which creates daily and weekly nmon
 scripts which are then collected to central zLinux reporting server.
 - Those nmon files are useful to our maintenance people, but we need also
 simple graphs to other parties preferably in some picture/html format.
 - Ideal solution would be some simple way to convert those nmon files to
 html pages automatically as nmon2rrd does.
 - One possibility would be to upload those nmon files to some AIX/x64
 server and do the conversion there, but it would create extra data transfer
 and to be honest would be quite embarrassing from zLinux point of view.
 - Is there any alternative routes to do this or should I try to compile
 some of these AIX/x64 tools to system z Linux?
 - We use Redhat 6.4 and z/VM 6.3

 Best regards,
 Mikael Wargh
