SLES15 SP3 Quarterly Update Images (QU4) released
Cross-posted to Linux-390, IBMVM, and IBM-Main All, SUSE has announced the release of the fourth quarterly update (QU4) images of SLES15 SP3. Quarterly Updates are refreshed ISOs based on GA and contain the last released updates. These updated ISOs are released every 3 months. While s390x is most likely the architecture of interest for this audience, we provide ISOs for all our supported architectures (x86_64, s390x, aarch64, & ppcle64), and for Vagrant boxes, and for JeOS (KVM and Xen, VMware, HyperV, OpenStack Cloud, Xen,). (JeOS = Just enough of an Operating System, pronounced as "juice.") To access this update, go to https://www.suse.com/download/sles/ Make sure the following two items are selected: - Under "Stable Releases": 15 SP3 - Under "Architecture": Z Systems Then scroll down and click on the link in the text on the right below the "Download" buttons: "Please login to SUSE Customer Center[1] for the latest installer images, update channels and your evaluation subscription details." After that, the entire page will look differently, because you're now accessing the SCC downloads. Scroll down and you'll see download links for: SLE-15-SP3-Full-s390x-QU4-Media1.iso and SLE-15-SP3-Full-s390x-QU4-Media2.iso. The Media2 image only contains source, so it will not be needed to perform an install. As the file names indicate, these are the "full" ISOs and can be used to perform brand-new installations or upgrades. Scroll further down and you'll also see: SLE-15-SP3-Online-s390x-QU4-Media1.iso and SLE-15-SP3-Online-s390x-QU4-Media2.iso. The Media2 image only contains source, so it will not be needed to perform an install. These are the "online" version of the install media. That means to perform a brand new installation, you'll need to either access the SUSE repositories for all the packages that have not been updated, or a local mirror of the packages, such as provided by SMT (Subscription Management Tool), RMT (Repository Mirroring Tool), or SUSE Manager. This was (hopefully) the last QU for SP3, the next one will be for SP4. Mark Post 1. You must create an account to access the SUSE Customer Center, or SCC.

Open Mainframe Project will be making a z15 available for all Open Source projects
Cross-posted to Linux-390, IBMVM, and IBM-Main At the Linux Foundation's Open Mainframe Project meeting this week, it was announced that beginning in 2023, the OMP will have a z15 available for any Open Source project that wants to make use of it. According to the announcement at https://www.openmainframeproject.org/press/2022/09/21/open-mainframe-announces-new-mainframe "...this mainframe infrastructure will be available for broad open source projects as a development, test, and continuous delivery environment, enabling developers within these communities to be able to support both z/OS and Linux on s390x." The z15 will be hosted at Marist College, adding to their already good-sized menagerie of IBM Z hardware. The hardware is being donated by Broadcom Mainframe Software Division. While we've had similar resources available for Linux-based OSS projects for some time, this is the first that I'm aware of the availability of no-cost access to IBM Z hardware for z/OS-based Open Source developers. It will be interesting to see if any more z/OS-based OSS projects come along to make use of this.

SUSE Linux Enterprise 15 Service Pack 4 is now GA
Cross-posted to Linux-390, IBMVM, and IBM-Main All, SLES15 SP4 has now been released. A fuller announcement in the form of a blog post is at https://www.suse.com/c/good-news-everyone-sle-15-sp4-is-now-released/ . The ISO images are available at https://www.suse.com/download/ or via your SUSE Customer Center (SCC) account. The release notes for SLES15 SP4 can be found at https://www.suse.com/releasenotes/s390x/SUSE-SLES/15-SP4/index.html . Given that nearly a quarter of the product has been updated, reading the release notes is strongly advised. Since the majority of SLES is common between all architectures, please read the entire document, and not just the IBM Z specific parts. ISO images for openSUSE Leap 15.4 are also available for IBM Z and LinuxOne at https://get.opensuse.org/leap/15.4/ . The full tree is available at https://download.opensuse.org/distribution/leap/15.4/repo/oss/ and https://download.opensuse.org/distribution/leap/15.4/repo/non-oss/ .

SUSE Rancher products for IBM Z
Cross-posted to Linux-390, IBMVM, and IBM-Main All, On May 3rd, 2022, SUSE announced that beginning tomorrow, June first, the following products will be available for IBM Z: - SUSE Rancher Manager - SUSE Rancher Kubernetes Engine 2 - Longhorn Storage For anyone not familiar with Rancher, which given this audience I assume is almost everyone , it provides "multi-cluster Kubernetes management," also known as "orchestration." The relatively short announcement can be found at https://www.suse.com/storage/partner/pa/announcements/all/2022/20318.html Unlike Red Hat's OpenShift product, SUSE Rancher should work with any modern Linux distribution. The intent is to support all IBM supported Linux distributions for IBM Z and LinuxONE. Of course we would prefer that you run it on SUSE Linux Enterprise Server, but that is not a requirement. For anyone inclined to torture themselves, significant amounts of marketing material can be seen at https://www.suse.com/products/suse-rancher/ Additionally, there will be presentations given on SUSE Rancher for IBM Z at both SUSECon, and SHARE in Columbus, Ohio. If you have any questions, feel free to contact your local SUSE sales representative, or call 1-800-796-3700.

Containers, Linux, and IBM Z, oh my
Cross-posted to Linux-390, IBMVM, and IBM-Main Almost five months ago, the SUSE acquisition of Rancher Labs closed. For those of you not familiar with Rancher, the public announcement referred to the company as "... the market leader in Kubernetes management." Even allowing for marketing puffery, industry analysts viewed it as a good move, for both companies. Now, SUSE is announcing its intent to provide the software on non-Intel/AMD hardware. The initial release for Linux on IBM z and LinuxONE will be a subset of the full Rancher product suite, while still enabling customers to derive value from it. The details on what will be included are in Mike Friesenegger's blog posting at https://www.suse.com/c/bringing-rancher-value-to-ibm-z-and-linuxone/ SUSE will be making further announcements about this in the future, so please say tuned.

SUSE Documentation on the web
Cross-posted to Linux-390, IBMVM, and IBM-Main All, In the wake of the separation of SUSE from Micro Focus, the publishing process for SUSE documentation is no longer owned by Micro Focus. This is a heads-up to warn you of the coming changes, and to solicit your help if problems are found. The new site, http://documentation.suse.com is not live yet, but hopefully will be this week. When it is, the current site, https://www.suse.com/documentation/ will not be accessible anymore. A redirect to the new landing page is in place. -- Expected Issues -- Because the new site is built with a completely different tool chain, the documentation team could not feasibly redirect all so-called "deep links" into the various manuals. (We now use a different guide structure, use different characters in file names, and create one page per chapter instead of one page per section.) This means that any bookmarks you have that point to specific chapters or sections in a document will no longer work. You will be redirected to the index for the relevant product. There is no direct replacement for the unauthenticated comment functionality of the old site. Most guides will offer "Report Bug" links next to section headline that help open a Bugzilla or GitHub issue (depending on the product). A suitable Bugzilla or GitHub login is necessary in this case. As always, if you have a contract with a support provider, opening a service request with them is also a way to report problems. In particular, if you find: * Dead links in the navigation * Dead links between documents * Missing documents please let us know so we can get the problem corrected.

You'll need to figure out who that is and have them either detach the disk, or re-link it as read only. As Jake mentioned, you could FTP it to another disk that is not currently in use, and then copy/move it. More than likely, PMAINT's 191 disk is also linked read-write, so you'll have to detach it first.

Bear in mind that as kernels get larger, and initrds get larger, those numbers may need to be massaged. In turn, that means the initrd.off and initrd.siz files will need to be regenerated. You should be able to run SLES11 on your machine. The release notes say that only z9 or later is supported, but that was a support limitation, not a technical limitation.

Given that the current hardware is as follows: System Architecture Manufacturer: SGI 161 racks (11,472 nodes) 7.25 Pflop/s peak cluster 5.95 Pflop/s LINPACK rating (#13 on November 2016 TOP500 list) 175 Tflop/s HPCG rating (#9 on November 2016 HPCG list) Total CPU cores: 246,048 Total memory: 938 TB 2 racks (64 nodes total) enhanced with NVIDIA graphics processing units (GPUs) 184,320 CUDA cores 0.275 Pflop/s total 1 rack (32 nodes total) enhanced with Intel Xeon Phi co-processors (MICs) 3,840 MIC cores 0.064 Pflop/s total and they're talking about current run times of "hundreds" of hours or longer, I don't think they'll be running any of this on a mainframe.

These two things, taken together, is what "wget -k" does. If you do a "wget -k -p" on a web page, you'll get all the elements of the page (excluding those defined in javascript), with the HTML modified to point to the local copy. For myself, I download all the Linux and z/VM presentations from the various SHARE conferences I attend. I wrote a shell script to download all the PDF files, and use the various HTML files to create symbolic links to them using the title of the presentation. It works well enough for my needs. On Linux systems the poppler-tools package contains a "pdfinfo" command that can print things like Title and Author from PDF files that contain them. This could aid in creating symbolic links via scripting as well.

Since it's part of the openSSH package, it uses the same type of encryption to transfer the data. If the sending process isn't checking the return code of the transfer, it may miss "out of space" problems, etc., but that would be a problem with the script, not SFTP.

I'm pretty sure the public key they provided you was not intended to be used in conjunction with RACF (or any other ESM). That looks like a "plain old ssh" public key. If you don't mind them accessing your system in this way (I have severe doubts about that), just put the key as-is into the target userid's .ssh/authorized_keys file and have them give it a try.

I and various other people have repeatedly tried to get IBM to stop publicizing how many virtual machines can run on a fully loaded z13 with no indication of what hypervisor needed to be used for that. z/VM would have a hard time hitting that oft quoted 8,000 number. KVM as it stands today wouldn't even come close. (Note that I expect KVM to continue to improve in this area, but I'm talking about "today.") The people who are responsible for both z/VM and KVM on z are trying to do the right thing by positioning KVM as the "entry level" hypervisor for mainframe customers that don't have access to z/VM skills but do have Linux expertise. I don't know how many people are listening to them. Certainly IBM marketing isn't. > rather than learning another two OS's (counting CMS as an OS, which it is in > a sense).

Since the current Rockhopper is, in terms of hardware only, simply a rebranded z13s, I would say that it's likely to be more successful than previous generations of the Business Class machines for Linux-only clients. I don't think there were all that many of those, in general. Some, but mainframe Linux customers tend to also be running other IBM operating systems. Having said all that, the general Linux community views all mainframes as weird. A lot of them come to love them once they get to know them, others continue to want nothing to do with them.

I have to pay? This would make ETJ nothing more > than > vanity publisher... Yes, and no. The vanity publisher aspect only comes into play when people are writing about something other than what their company sells. I ran into this same problem when I changed jobs and started working for Novell, and now SUSE. Previously I was able to write for ETJ (then zJournal) and get paid for it. When I became the employee of a "vendor" that stopped, and my employer would have to pay for having any articles I wrote published. Even though I don't do marketing of any kind, and am vendor neutral as possible. Now, their rationale isn't completely bogus. They have a lot of companies out there that basically want to publish product promotional articles without them being labeled as such. If someone like you and I were to get published, with or without being paid, those other companies jump all over Bob Thomas about it. This sort of thing is also why IBM stopped paying for non-employee non-customer speakers to present at their conferences. Also an overly simple-minded solution. So, I haven't written for ETJ for years now. (The last article I actually wrote was published under the name of another well-known contributor, not mine.) They were always having problems attracting writers for Linux articles, and I've noticed they haven't had a "pure" Linux article published for quite a while, which is a shame. I didn't mind the loss of income so much, since I was using the funds to donate to a local dog rescue. But the blindly binary decision making ticked me off, particularly since they were already familiar with my work and regularly requested more of it before I changed jobs. Oh well.

This is likely to be due to having an incorrect network setup. After you get the "No repository found" message, you can enter "x" as a response, and then 3 (I believe) to start a shell. Once in the shell you can display the networking information with ifconfig, route, etc. I don't think there's a ping command in the installation initrd, but I could be wrong. I think you'll find it much (MUCH) easier to do your first install as a z/VM guest. If you set up the virtual machine with the same (virtual) addresses as will be present in the native "LPAR" install, you should be able to transfer your work to that environment quite easily later on. If you have further problems, feel free to contact me off list, or post to the Linux-390 mailing list where most of the mainframe Linux folks hang out.

IBM doesn't give out a lot of numbers, but they do like to sprinkle some about. They say that 80 of their top 100 mainframe customers are running Linux on the mainframe. Sales of IFLs have increased every year since they were introduced. A lot of that is to existing customers, but not all. They talk about "new to the mainframe" customers each year, and a lot of those (but not all) run Linux. My company has over 1,000 Linux on mainframe customers, including two of the largest in the world. IBM itself is also quite a large customer, and not just due to their "Project Green" consolidation efforts. I know that Isracard has been a Red Hat customer for quite a while now.

Are these Linux systems running on z/VM as the hypervisor? If so, stop DEDICATEing DASD volumes to them and make them minidisks from cylinder 1-END. That way, z/VM will be in control of the volser and z/OS shouldn't be seeing duplicates after that.

I don't know the answer to your question, but I might be able to point you in the right direction. I have never received a new version of z/OS on a DVD. Have you? Is it able to be IPLed from the HMC? If so, then there is almost certainly a file in the top-level directory that ends with a file extension of .ins. Look at that file. It will point to the other files on the DVD that get loaded to actually perform the IPL. If you can figure out how IBM did it, you should be able to duplicate the technique using your sysres.

That being said, Just to be clear, when you talk about "port it to zSeries" do you mean z/OS, or Linux running on z? If the latter, then there won't be much, if any, porting involved.

The answer to this greatly depends on your final target, z/OS or Linux on z. If the latter, then you probably want to go with SUSE since that has by far the largest share of the market on z as well as the most software certifications, etc. (Yes, I work for SUSE but I try to be objective about things like this.) If the answer is z/OS, then as others have pointed out the choice of Linux is more of a matter of what your personal goals are regarding learning. To me, if you want to learn Linux, really learn it, then go with Slackware. You'll have little choice but to learn how things work since Patrick Volkerding's approach to Slackware is that system administrators don't need or want much hand holding. You'll also find that a large number of people who have lots of experience in Linux started out with Slackware early on. Other questions you need to answer are if you want to buy support for your Linux. That will greatly limit your choices. If you want something that's very easy to use and looks pretty, then various derivatives of Debian such as Ubuntu, Mint, etc. are good. And on and on and on. The list of things to consider can be very large. The good thing is that you can try a bunch of various distributions with no monetary cost, just the time and effort you devote to downloading, installing and playing with them. That's true even for Red Hat and SUSE. The versions you can download are identical to what their paying subscribers get. The difference is in support and maintenance. Another thing to think about is finding a local Linux Users Group (LUG). There are a lot of them out there and the people you meet there can be a big help.

There are ways to pass information to z/VM as to what console to use. I'm not familiar enough with that to really help you.

Aside from what others have mentioned, an additional thing you could do is with every IPL, do an "rm -rf /tmp/*" command. This will replicate the previous behavior in that everything goes away with an IPL, so there shouldn't be a significant backlash from it.

The install process starts with the "Load from Removable Media or Server." That media can be a DVD in the HMC, or an FTP server somewhere on the network. The HMC looks for files that end with "*.ins" and displays the list of them on the HMC.

The suse.ins file looks like this: boot/s390x/linux 0x boot/s390x/initrd.off 0x0001040c boot/s390x/initrd.siz 0x00010414 boot/s390x/initrd 0x0100 boot/s390x/parmfile 0x00010480 What I would recommend is that Connor keep his FTP server updated with whatever kernels, ramdisks, and parmfiles he has installed on his storage array, and use the HMC to boot from them. (These would need to be extracted from disk to the FTP server after every update to the kernel or parameters.) In the parmfile, you can point to where the root file system lives, and the initrd would have the code necessary to activate the SCSI over FCP connection to mount it. It's a bit of a PITA, but should work just fine until such time as he either gets the SCSI IPL feature from IBM installed, or he finds some ECKD storage at a reasonable price.

If you do, however, I've seen a number of jobs that require mainframe skills, as well as Linux, and even z/VM. Since that seems to fall into your areas of interest, you might want to consider it.

But that's not the point of the distinction. The point is that you may get the software for no cost, or for some cost. BUT, no one can take away the _freedom_ you have to use that software in any way you want. The emphasis on the slogan is on the freedom part _for everyone_, not just the person that created the software. The slogan was created to get native English speakers to think about the freedom aspect, and not think that it only related to price. If you're really curious, there are lots and lots of resources on the web that talk about a lot of the implications of this, both for the author and people who want to use the software for various other purposes. But, for the FSF, the main thrust is that Free/Libre software can't be made proprietary by others, and you can't be restricted in what personal use you want to make of it.

It's been quite a long time since I worked with UNIX System Services, but I would think that you would only be starting an NFS _server_ process, not for a client. An NFS "client" would be the mount command to mount the exported file system into your HFS/ZFS.

That's the whole purpose of KVM, on any architecture. What would the effect be of running KVM in a Linux instance under z/VM? Pretty bad performance, to start with. The z/Architecture only provides 2 layers of SIE (start interpretive execution). PR/SM takes up one, z/VM would then take up the second, leaving Linux without that huge boost. And of course PR/SM is still dispatching logical IFLs onto real IFLs...or are we eliminating PR/SM on the LinuxONE and perhaps going back to a version of MFT? Not at all.
