Final Meeting Agenda:

9:00 AM Bacula, No Silver Data Cartridges, Please...

In previous sessions, I've talked about Linux backups with Amanda, and
integrating Amanda and HSM processing. Bacula is a rapidly developing
open-source backup and recovery utility that is considerably more
sophisticated than Amanda, bordering on being competitive with the
commercial backup utilities, and has recently received a number of
mainframe-specific enhancements that make it very attractive as a backup
solution for Linux guests on VM and other systems throughout the
enterprise. In this session, I'll give an overview of Bacula, the
integration code SNA has contributed to add tape library support and ANSI
label support, and how to set up a Bacula server using the tools provided.

The speaker will be David Boyes of Sine Nomine Associates.

10:30 AMCoffee Break

11:00 AMLow-Cost File Level Backup for Linux on the Mainframe: A
Backup Appliance for Linux on zSeries (new updates!)

This session describes a method for doing file and DR backups for Linux
systems to VM and/or z/OS-controlled tape drives without connecting tape
drives directly to Linux. The session describes Linux tools, z/OS and VM
configuration, interaction with SMS on both platforms, and includes a
configuration that can back up virtual machines and discrete machines using
the existing mainframe tape resources. .

The speaker will be David Boyes of Sine Nomine Associates.

12:30 PMLunch Break

1:30 PM Administration and Vendor Announcements

2:00 PM Linux appliance to cross-communicate with z/OS or other
Operating Systems

Bringing TCPNJE To The Rest of the World: Our Latest Research Widget

NJE services are deeply embedded in almost all the IBM operating systems,
and there are many useful services that can be provided message
logging, unattended file transfer, printing to open-systems printers... if
only there were a way to allow open systems to play in the NJE world! Also,
the z/OS folks are still stuck in the Dark Ages requiring SNA
communications links and VM/VTAM just to play in the NJE world.

We've been working on a Linux-based NJE appliance to demonstrate some of
the techniques required to build focused Linux systems that augment
traditional mainframe applications, and a full-scale NJE implementation for
open systems (including Linux Intel, Windows and Palm client/servers!) fell
out of the solution to the problem.

I'll talk about some of the requirements for constructing a NJE appliance,
the addition of a CTC driver to Linux on zSeries, outline some of the
interesting system management and automation that is possible once NJE
connectivity is present, and hopefully (network connection permitting)
demonstrate a direct connection between RSCS and a Intel Linux system to
show off our new toy.

The speaker will be David Boyes of Sine Nomine Associates.

3:15 PM Coffee Break

3:30 PM Managing Performance in z/VM

Mac Holloway is a development manager for IBM Tivoli. He will be presenting
the Tivoli history and roadmap for managing performance in the z/VM
environment. This will include both the long-time IBM and Candle products.
The future will be based on the OMEGAMON XE/DE infrastructure and address
the z/VM and Linux guest performance data correlation. The OMEGAMON XE/DE
infrastructure provides an extensible framework for identifying and
debugging performance problems across platforms and applications.

The speaker will be Mac Holloway of IBM/Tivoli.

4:45 PM Free-for-All

Members will attempt to answer any reasonable VM or hardware related
questions. If you are having a problem and want to find out if others are
experiencing it, or you are installing new hardware or software and want to
find out what types of problems others have experienced, here is the

AW: Fwd: SLES9 losing network connectivity

2005-06-21 Thread Leonard Janus
HI,

the QIOASSIST problem occured in our installation with VM440.
We installed PTFs:
UM31170, UM31340, UM31370
Due to the conversion to VM510 we ran only 3 weeks with these ptf's -
without a new occurrence of the error.

VM510 was shipped with the appropriate ptf's installed (I don't know the
numbers).

So I don't know if there are any more needed/available.
Regards
Leonard

  While we haven't lost connectivity with our SLES9 and or SLES8 images,
installing SLES9 is/has been an adventure for connectivity. It takes
several to many tries to install a SLES9 image in that pinging the gateway
doesn't happen until after several tries. Once past that, we've seen no
problems and we are a z/VM 5.1 shop. Now not knowing where the problem is
I'd still say something in either SLES9, z/VM 5.1 or the OSA code needs fixed.



So I don't know if there are any more needed/available.

New URL for Linux on zSeries developerWorks web pages

2005-06-21 Thread Gerhard Hiller
Some of you may already have noticed that the Linux on zSeries
developerWorks-pages are available at the new URL:
http://www-128.ibm.com/developerworks/linux/linux390/

Some time later today (Tuesday 2005-06-21), re-directs from our old URLs
will start to be effective, re-routing links to pages on:
   http://awlinux1.alphaworks.ibm.com/developerworks/linux390
   http://www10.software.ibm.com/developerworks/opensource/linux390
   http://oss.software.ibm.com/developerworks/oss/linux390
to the corresponding page at the new URL.

It may be a while until the re-directs are effective, completely, but it
is time to start changing your bookmarks and links on web-pages to
Linux on zSeries developerWorks (if you haven't already done so), as the
re-directs will not be in place for ever.  Please use:
   http://www.ibm.com/developerworks/linux/linux390/   ...for online links
   ibm.com/developerworks/linux/linux390/  ...in print

Note: We strongly advise to *NOT* use the www-128.ibm.com, but leave the
  -128 out and type it as above.

Here is a summary of the changes effective on our new URL:
 - Previously, our web-pages were *.shtml, now they are *.html.
   -- The re-routes being set up should handle this change.
 - For the web-pages, directory-structure and [file-]names of the
   web-pages remain as before (except for the URL-handle, of course).
 - All patches, packages, OCO-modules will remain on the awlinux1-server
   for a while - but will be moved to an ftp-server in the next few months.
 - The PDFs with the manuals for our streams and documentation-downloads
   from the Tuning hints  tips are available on an ftp-server.

Here is some guidance for linking to our pages:
 - Please do not link to downloads (patches, OCO-modules, PDFs, etc.) from
   our pages, directly, but refer to the html-page where the link is shown.
 - Specifically, please do not link to PDFs, but to the Documentation
page
   of the stream.
   As we found a lot of references to (old versions of) PDFs, we have
   established documentation archives for the active April 2004 and
   June 2003 streams (referenced on the Documentation page), with links
   to superseded (but still available) editions of the PDFs.

Re: Install problem again

2005-06-21 Thread Daniel Jarboe
 I can´t get by the initrd 75% problem when installing.

Is this for x86?  Was a little confused at all the i386 talk in your email.

Otherwise, this sounds similar to an experience we recently had.  When using 
either the SLES9 or SLES9-SP1 installation images the process would hang with 
zipl (would stall at 75% on the progress bar).  This problem was z/VM related.  
Sometime earlier in the install process pdflush would die with an illegal 
operation in do_writepages (calltrace was printed to the z/VM guest's console).

One workaround might be to turn off all linux swap during the install (and run 
the install with at least 512MB storage).


At IBM's recommendation we switched the root installation filesystem from 
cramfs to ext2 (replacing sles9/CD1/boot/root and increasing the ramdisk size 
appropriately in sles9/CD1/boot/parmfile).

If this sounds like the same situation and disabling swap doesn't help you, you 
can email me offlist for instructions to create the ext2 root.

Or if it hasn't been removed yet you might still be able to

wget ftp://testcase.boulder.ibm.com/linux/fromibm/24487/root.ext2

and save yourself some time.  This fs created for the SLES9 GA installation 
process.  The new parmfile should read:
ramdisk_size=196608 root=/dev/ram1 ro init=/linuxrc TERM=dumb

Redbook From LPAR to Virtual Servers in Two Days is available

2005-06-21 Thread Michael MacIsaac
Hello list,

The redbook z/VM and Linux on zSeries: From LPAR to Virtual Servers in
Two Days is on the Web (finally! 52 days late) at:
http://www.redbooks.ibm.com/abstracts/sg246695.html
The files associated with this book are on the Web at:
ftp://www.redbooks.ibm.com/redbooks/SG246695/

The book describes how to roll your own Linux virtual servers on IBM
eServer zSeries under z/VM. It adopts a cookbook format that provides a
clearly documented set of procedures for installing and configuring z/VM
in a logical partition (LPAR) and then installing and customizing Linux.
This book is based on SUSE LINUX Enterprise Server 9 (SLES9) for zSeries.
In addition, it addresses both 31-bit and 64-bit distributions.

This redbook also covers the associated REXX EXECs and Linux scripts to
help speed the process. These tools are not IBM products, nor are they
formally supported. However, they will be informally supported. You can
find these scripts on the ITSO Web site as explained in Appendix B,
Additional material on page 221.

This IBM Redbook is written for those who want to achieve a quick start
with z/VM and Linux. Prior to reading this IBM Redbook, you must have a
general familiarity with zSeries technology and terminology. You do not
need an in-depth understanding of z/VM and Linux. And to properly follow
the procedures documented in this book, you need a zSeries LPAR with
associated resources, z/VM 5.1 media, and a Linux distribution. Following
is the table of Contents

Chapter 1. Introduction to running z/VM and Linux on zSeries
Chapter 2. Planning
Chapter 3. Configuring a desktop machine
Chapter 4. Installing and configuring z/VM
Chapter 5. Configuring an NFS server
Chapter 6. Installing and configuring Linux
Chapter 7. Configuring NFS on the controller
Chapter 8. Configuring Linux for cloning
Chapter 9. Basic Linux virtual servers
Chapter 10. Virtual communications server
Chapter 11. Virtual communications controller server
Chapter 12. Monitoring z/VM and Linux
Chapter 13. Backup and restore
Appendix A. z/VM options
Appendix B. Additional material

Thanks to all who contributed. It was a long haul: hopefully the fruits
are worth the effort.

Which file system?

2005-06-21 Thread Joe Nocket
We are migrating a DB2-UDB LINUX/390 SLES 7 server with the EXT2 filesystem
to a  SLES 9 server. Because of the nature and size of the databases we
encounter a lot of issues with the 2 GIG file size limit (database
containers, backups to disk, export and load files etc.). The long restarts
after a failure on EXT2 is also an issue. We're looking for comments?
insights? on the journaled filesystems  EXT3, ReiserFS, XFS and JFS. Which
is the best filesystem to support large database files with good performance
and good reliability?

Re: Which file system?

Hearsay says that ReiserFS is a very poor performer on the zSeries. EXT3 would 
be easiest because EXT3 is simply EXT2 + journelling. You can convert your EXT2 
to EXT3 in place. But I don't understand the comment about the 2 Gb file size 
limit. I no longer have Linux on zSeries, but there is no such limit on my 
Intel box (kernel 2.4.20).

Re: Which file system?

2005-06-21 Thread Fargusson.Alan
There is not a 2G file size limit on EXT2.  I suspect that you are using an old 
version of DB2 that is not compiled with large file support.  If this is true 
then it does not matter what filesystem you use.  Another possibility is that 
you are using a very old kernel.  I think the 2.2 kernel has a 2G limit.  I am 
not sure about 2.4.  I know that 2.6 does not have a 2G limit.  When you move 
to SLES9 you should be running a kernel without a 2G limit, so you might want 
to test and make sure that you are hitting a 2G limit on SLES9.  If you are 
hitting a 2G limit with EXT2 on SLES9 then DB2 would definitely be the problem.

 Subject:  Which file system?

 We are migrating a DB2-UDB LINUX/390 SLES 7 server with the EXT2
filesystem
 to a  SLES 9 server. Because of the nature and size of the databases we
 encounter a lot of issues with the 2 GIG file size limit (database
 containers, backups to disk, export and load files etc.). The long
restarts
 after a failure on EXT2 is also an issue. We're looking for comments?
 insights? on the journaled filesystems  EXT3, ReiserFS, XFS and JFS. Which
 is the best filesystem to support large database files with good
performance
 and good reliability?

I'm z/VM 4.2 running SLES9 with SP1.

Do you have any indication on what kind of problems I may be having
running Linux?

I'm not saying that I don't have problems, just I'm not sure what
problems are mine and what problems are due to z/VM 4.2G.

The only think I can think of is in the realm of communications.  Guest
LAN support, OSA and that sort of thing.  Need PTFs to CP to be able to
use Guest LAN support for example.  But I don't think that is really a
Linux thing.  More of fixing the support in CP type of thing.

 HI,

 the QIOASSIST problem occured in our installation with VM440.
 We installed PTFs:

 Due to the conversion to VM510 we ran only 3 weeks with these ptf's -
 without a new occurrence of the error.

 VM510 was shipped with the appropriate ptf's installed (I don't know the

 So I don't know if there are any more needed/available.

FCP tapes

2005-06-21 Thread Sue Sivets

Has anyone tried adding FCP tapes to linux. I was able to add FCP dasd
to Suse v8 and I'm in the process of adding them to Suse v9, but I'm
getting nothing but error messages when I try to add an FCP tape device
to either system. I suspect, but I'm not sure, that I've probably got a
problem with the device lun (aka FCP lun in v9). Is there any way to
find out what the device lun really is? Both versions of Suse are
running under z/VM 5.1, and as far as I can tell VM can see the
mainframe device numbers (ucbs?) and recognizes that they're FCP.

risk if I relabel an LVM DASD Volume

2005-06-21 Thread Uriel Carrasquilla




Question:
would my volume-group and logical-volume (LVM) be in trouble if I re-label
one or more of the physical volumes allocated to the lv?
I forgot to label the volumes when I created them and my zOS guy is getting
them in his reports (bad label).  We use zOS DF/DSS for backups so I am
very much forced into having the correct label.
I was thinking to IPL SLES-9 without the LVM's in /etc/fstab.  That way I
could do the fdasd -l xxx.
My other option is to backup the data, delete the LV-group/volume.
Re-label.  Then put it back.  A lot of work.
any suggestions are welcome, except killing the zOS guy.

could do the fdasd -l xxx.
My other option is to backup the data, delete the LV-group/volume.
Re-label.  Then put it back.  A lot of work.
any suggestions are welcome, except killing the zOS guy.

Re: /tmp as a logical volume

2005-06-21 Thread Post, Mark K
I build all my systems with /tmp separate from /.  That goes for Linux/390 and 
Intel Linux.  SLES9 will handle it nicely.

I'm beginning to have doubts about LVM (version 1 at least) on 64-bit systems.  
I've had two cases where my volume groups have disappeared after an IPL, and 
hence all my logical volumes.  Emails to the linux-lvm mailing list have gone 
unanswered.  I don't know if it's because I'm running Linux/390, LVM 1 or what. 
 Having said that, if you're going to use LVM, using it for /tmp is certainly 
the safest.  According to the FHS, the contents of /tmp are not guaranteed 
across a reboot anyway.

Subject: /tmp as a logical volume






We have /tmp as part of the / (root) file system in one 3390 volume (m9).
I was wondering what reaction I would get from this list if I was to create
a logical-volume (lvtmp), part of an existing volume-group (vgsys01) and
mount it as /tmp.
Would SuSE SLES-9 be ok with it?
what are my risks if under LVM?
would I be able to IPL if the LVM gets damaged and I just change my
/etc/fstab to remove the reference to /tmp?
any suggestions, comments and ideas are welcome.
