Linux for Big Iron

Linux for System z, also known as Linux/390, is the native port of Linux to the S/390 and IBM System z hardware platforms. It runs on the bare hardware, in an LPAR and as a VM, or z/VM guest.

LinuxVM.org is the official home of the Linux/390 project. The purpose of the project is to provide a central source of Linux/390 information and software, and to explore the possibilities of Linux and CP integration or interoperation.

There is a nascent wiki dealing with Linux on z/VM at wiki.linuxvm.org that is intended to be another resource for community-provided technical information.

The list of Linux/390 Redbooks was getting a little too unwieldy to remain on the front page, so it has been moved to its own page.

      [PATCH] Fix idle time field in /proc/uptime

09/24/2009 - Mike MacIsaac and Brad Hinson announced an updated version of the "Sharing and maintaining RHEL under z/VM" paper. The new version is based on RHEL 5.3 for System z and has some additional updates:

  • No modified initialization script is necessary because RHEL's /etc/rc.d/rc.sysinit allows for read-only root file systems (using the "readonlyroot" command line parameter).
  • All read-write file systems on a read-only root system are maintained under /local/. In the previous papers, /var/ was its own minidisk.

09/16/2009 - Mark Post announced the creation of a Wiki dedicated to Linux and z/VM.

The idea of having a Wiki for mainframe Linux and z/VM has been floating around for some time. It was thought that having a Wiki with a fair amount of content already in it would help it reach a "critical mass" of usability far sooner than might otherwise happen. A fair amount of behind-the-scenes work has been done over the last couple of years to make that happen, without much success.

So, I've decided to take a different approach. With the assistance of Marist College (and Velocity Software who owns the domain name), I've put up a Wiki at http://wiki.linuxvm.org/wiki/ for people to contribute content. We'll see how things go from here to determine if it's worth keeping or not.

There are a few rules, for lack of a better term, that will apply to the Wiki, none of them particularly onerous:
  1. Although technically not required, we would prefer that anyone contributing to the wiki create an account before doing so.
  2. Keep things civil and professional, both in the articles themselves, as well as the discussion pages for them.
  3. Keep things accurate. We expect vendor-specific information to be entered here (although we'd prefer to not have pricing details). But, any exaggerated claims, vapor ware announcements and the like are subject to summary deletion.
  4. Try to keep bias to a minimum. Everyone has their favorite distribution or way of doing things. Try not to let others people's preferences in those areas be cause for any Holy Wars [TM].
  5. If you don't own the copyright to something, don't add it to the wiki.
  6. Use common sense in general.
I hope that people find this useful, and are willing to contribute as they are able. With any luck, it will become a valuable resource for everyone that might become involved in running Linux on System z.

08/27/2008 - Brad Hinson announced that a new draft Redbook was now available on the IBM Rebooks site: z/VM and Linux on IBM System z: The Virtualization Cookbook for RHEL 5.2
Some highlighted changes from the RHEL 5.0 book:

  • z/VM updated from v5.2 to 5.4
  • Moved away from dual boot approach, in favor of separate master image
  • LVM now used for system OS partitions
  • Completely rewritten clone script, with support for LVM
Brad also gave special thanks to Mike MacIsaac and Lydia Parziale, as well as Roy Costa and Marian Gasparovic for all of their hard work on these cookbooks.

08/26/2008 - The autoinst.sp2.zip file was updated to ensure that the 3390 DASD volume always has dasdfmt run against it. For brand new, never before used for Linux/390 volumes, this prevent the installer from not being able to create partitions and file systems. The downside, of course is that all installs will now incur the overhead of running dasdfmt.

07/02/2008 - The June archives of the Linux-390 mailing list have been added to the archives page.

06/05/2008 - An updated version of the bash script that will generate an AutoYaST file for a more-than minimal installation has been added to the Patches page. This version is for SLES10 Service Pack 2.

Note that "more than minimal" is not overstating things. A good number of packages that really should be installed on any given system are excluded. You should review the remove-packages section of the template and delete entries that you want installed on your systems.

Also included in the .zip file is a diff to the gen.template script which will add the section necessary to auto-register your system with the Novell Customer Center. After applying the patch, all you need to do is edit the gen.template file to change the the fields designated with XXXfieldnameXXX to the values appropriate for your installation. The values requiring customization are:

  • email: The email address associated with your NCC account
  • regcode-sles: The activation code you received with your subscription
  • submit_hwdata: Whether the system should send hardware information about your system to NCC (yes or no)
  • submit_optional: Whether the system should send "optional" information about your system to NCC (yes or no)

05/11/2006 - Mark Post announced that he was now now able to provide Linux/390 DVDs for people that want them:

Thanks to the vast generosity of John McKown, I now have a DVD burner on one of my Intel Slackware systems. As I said in a previous post, I am now willing to provide DVDs of any freely available Linux/390 distribution that you can find .iso files for. (If you want one for Slack/390, I'll generate one and burn it for you.)

There will be a nominal fee, to cover postage, media, and a small piece of my time. I'm guessing USD $5.00 or so until I have an opportunity to actually send one out. After that, I may adjust the cost. If so, I'll let everyone know.

So, anyone that would like to order one, please contact me OFF LIST, and we'll work out the details.

Thanks again to John for his generosity,

05/03/2005 - Adam Thornton recommended installing Sarge and Debian-installer, instead of Debian Woody. "You'll get a much-closer-to-current Debian system that way. I haven't actually tried RC3 myself, but rc2 worked fine. I've heard some reports that virtual Hipersockets don't work but I have not been able to reproduce that.

04/29/2005 - A list member wanted to verify that some new SLES9 installs had actually picked up the Service Pack 1 maintenance. Mike MacIsaac said that a "uname -a" command should show a kernel level of 2.6.5-7.97. Ihno Krumreich of SUSE recommended using the SPident command. He said that "SPident -v -v" will show information on which packages are at which service pack level.

04/22/2005 - Robert Nix reported the resolution to a problem with communicating between DB2 systems on Linux/390 and z/OS that had been driving him crazy.

On roughly half the requests [from the Linux guest], Work Load Manager would route the request via XCF to the other half of the sysplex, which would process the request, and then send it.... Where? I[t] had no idea how to reach the source of the request, because the network the request came from existed only inside the CEC of the other half of the sysplex. Since it didn't know where to find the IP address, the response got thrown out to the defaultnet IP address. With some research, we figured out that it actually made it all the way back into the z/VM box. But the z/VM TCPIP stack had no idea that the hipersocket network existed either, and so it went to (you guessed it) the defaultnet address. Which bounced it back into z/VM. Which... Well, you get the picture.

Adding a route to the z/VM stack to route the request back into the Linux image completed the circle and allowed all the requests to be processed, but is not the optimal solution. I'm currently negotiating with our networking people to get a route put into the second z/OS to route things back across XCF to the hipersocket. At that point, I think things will be as optimal as I can get them.

04/22/2005 - A list member wanted to move a Linux/390 system from being a z/VM guest to running in an LPAR. Jim Sibley warned that if minidisks had been used for the guest's DASD that it would not work. In that case, data would have to be copied to new volumes before trying to IPL the system in the LPAR.
http://www2.marist.edu/htbin/wlvtype?LINUX-VM.54090


04/22/2005 - In response to what has become a common complaint when trying to install SLES9 systems, Jerry Whitteridge reported that the SLES9 FTP installation "requires a relative path. I had to specify ../../SLES9/INSTALLROOT in the ftp path instead of /SLES9/INSTALLROOT. After that everything worked OK -- it appears that the ftp server drops you into /home/&UID and that it uses that as the root for the FTP directories." Tom Duerbusch got essentially the same result by turning on the chroot option on his FTP server. He was then able to specify an absolute path instead of a relative one, since the FTP servers was then treating the home directory as "/" instead of "/path/to/homedir" The error that is reported when the path is not specified correctly is "Cannot read package data from installation media. Error no proposal."

04/21/2005 - In response to a question about creating a gcc cross-compiler for Linux/390, several people had some suggestions. Jochen Friedrich recommended reading the page at bytesex.org. Rob van der Heij said that he had good results from Kegel's crosstool. He warned that the "challenge is to get the runtime libraries at the right level with the proper patches to build against." Mark Post commented that the bytesex.org page had "cheated" by copying the glibc libraries from another source, and agreed that building those were very difficult. Carsten Otte said that the Debian packages from debian.speedblue.org has worked nicely for him.

04/21/2005 - In response to a question about creating an installation directory structure from the multiple Red Hat Enterprise Linux 4.0 AS CD images, NoŽL Antonio said that the Red Hat instructions did mean exactly what they said: "You can't go wrong if you do as the guide says: (repeat for each CD-ROM):

  1. Insert CD-ROM
  2. mount /mnt/cdrom
  3. cp -a /mnt/cdrom/RedHat <target-directory> - where the <target-directory> is one single directory
He went on to say "If you just need basic services like web and ftp and don't need a lot of the development utilities, then 2.3GB will easily suffice."
http://www2.marist.edu/htbin/wlvtype?LINUX-VM.54088


04/20/2005 - Mark Post reported an article that talked about Resolvo Systems contributing its "MoveOver Windows-to-Linux migration tool" to the open source community. A Sourceforge project has been created as well. Mark noted that even though the tool was intended to be used to migrate desktop files, it might be possible to use it to move server data as well.

04/19/2005 - David Boyes noted that the Sine Nomine "tape mount daemon and some sample execs to label tapes for use with the ANSI/IBM SL support in Bacula 1.37 are now part of the Bacula distribution. If you've been holding off due to support from the Bacula team, now it's there...8-)"

04/19/2005 - In response to a question about migrating Samba user and machines accounts to an LDAP server on SLES9, Mike MacIsaac recommended using YaST to do the setup, and referred to his two presentations from SHARE 104 for more information. David Boyes mentioned that the Samba HOWTO document on samba.org has a very detailed cookbook on the account migration aspect. Mike warned that the lmPasswd and ntPasswd fields are very important.

04/15/2005 - Rich Smrcina announced that he has written a syslog daemon for VSE. "It's sole purpose is to receive syslog messages from a Linux (or any compatible Unix) system. When a message is received it is displayed on the VSE system console. Console automation software can then use the message to trigger an action, for instance, to submit a job."

04/15/2005 - Adam Thornton of Sine Nomine Associates announced that version 0.5 of SysVInit has been released. "Improvements over 0.4 include support for VSWITCH coupling for Linux guests and global VM performance settings. Barring the discovery of major bugs, this is likely to be the last release before 1.0."

Adam did warn of one know issue. "SysVInit generates log files on AUTOLOG1's 191-disk, but does not automatically clean them up. So every so often you need to purge them manually, or your 191-disk will fill up and then PROP will fail to run. This behavior has been present in every release of SysVInit, so if you're running it at all, you should probably check your 191-disk and clean it up if necessary."

04/08/2005 - In a discussion about how to add a new network interface to a SLES9 system without using YaST, David Kreuter talked about copying the configuration files from /etc/sysconfig/network, and then modifying them. Hannes Reinecke of SUSE added this comment: "And do not forget to copy over the hardware configuration file in /etc/sysconfig/hardware/hwcfg-XXX and modify it with the appropriate parameters. Have a look in /etc/sysconfig/hardware/skel for samples. Full description can be found in /usr/share/doc/packages/sysconfig/README.s390."

04/06/2005 - In response to a request for any information about NJE/RJE interoperability tools that would allow a Linux/390 system to submit jobs to z/OS, David Boyes of Sine Nomine announced that they had developed commercial tool to do just that.
"We've developed a NJE implementation for Linux on (Intel, PPC, zSeries), Solaris, AIX, and HP/UX. This gadget allows use of standard NJE networking capabilities for file transfer, printing and interactive messaging to communicate bidirectionally from any of the above OSes to/from NJE-enabled operating systems as a peer. Full NJE routing and multi-stream capability is supported, as is SENDFILE and msg support (and as soon as I finish the CTC testing, I'll add support for syslog message log transfer to PROP or other NJE-based tools).

"The current implementation supports TCPNJE with RSCS and VSE; a maintenance release in August (we're still testing with some of the more esoteric stuff) will support real CTC connections. It is supported for LPAR and VM guests, and the CTC version will support JES(2,3), and TPF as well. It can be installed on an existing Linux or Unix system, or supplied as a appliance (OS and application together). The CTC version supports up to 32 CTC connections and a large number (limited by storage) of TCPNJE connections. No VTAM or other communications engine (such as CS for Linux) is required -- this is a completely native implementation.

"The implementation includes cmdline utilities for MSG and SENDFILE, mail and printer interface, and a API programming library. The TCPNJE support uses SSL encryption for TCP connections (compatible with the SSL Server Enabler) if you enable it and are running on an OS with SSL wrapper support."

04/04/2005 - Christian Borntršger of IBM said that he would look into a performance problem of a SLES9 user that was seeing a 30 second delay during some system IPLs when the hotplug code was detecting 32 processors. This was happening on a Multiprise 7060 with 1 CPU. Christian said that VM APAR VM63654 should be installed on any system that was going to be using CPU hotplug, but a 30 second delay could probably be improved upon.

03/25/2005 - Steve Gentry spotted a draft version of a new Redbook, "z/VM and Linux on zSeries: From LPAR to Virtual Servers in Two Days, SG24-6695." The abstract states:
This redbook describes how to roll your own Linux virtual servers on IBM zSeries under z/VM. It adopts a cookbook format that provides a clearly documented set of procedures for installing and configuring z/VM in an LPAR and then installing and customizing Linux. You will need a zSeries logical partition (LPAR) with associated resources, z/VM 5.1 media, and a Linux distribution. This book is based on SUSE Linux Enterprise Server 9 (SLES9) for zSeries, and both 31-bit and 64-bit distributions are addressed.

03/24/2005 - Neale Ferguson and Mark Post spotted some news coming out of Novell's Brainshare conference. The "Department of Transportation for the State of Oregon is migrating critical components of its driver's license management system to Novell's SUSE Linux Enterprise Server running on an IBM zSeries mainframe."

Steven Adams of ODOT provided a little more information: "Actually we have been running a bit longer on that system but the headline is a little misleading (the entire release explains it in detail). The Linux piece is a single, critical, component of the entire licensing system. When we originally spec'd it out we knew that the aged, vintage, OS2 system had to go and the cost of replacing that component with an Windows system would be costly (roughly 120k) we took it on in our shop. Turned out to be a pretty quick infrastructure piece and it's been solid and secure since I finished it up. It was a natural fit since all of the other system components, except the workstations, are CICS/HFS based."
