Adding virtual CPUs to a running Linux guest
Folks, I need to purcahse a clue.I have a Linux guest (SLES10, SP1), running on z/VM 5.3. The directory entry for the guest has a MACHINE ESA 2 statement in it. Thye Linux guest was booted with only one virtual CPU defined. I would like to define and bring online the 2nd virtual CPU, without having to stop and reboot the Linux image. Can Linux handle the addition of an extar CPU while it is running, and, if so, how?

Hitachi DASD subsystem Replication - anyone?
Background: in a predominently zOS sysplex environment (2 z9's) and a fairly large Open Systems environment (Linux, Solaris, AIX, Windoz), a recent storage subsystem consolidation/upgrade decision was made to purchase an Hitachi USP1100 on a large tiered storage platform. Problem : with zVM and zLinux, while growing rapidly, it doesn't yet get the *attention* it needs considering resources and tools. Example, we have been running around 4 years on 2 IFL's on an old DASD subsystem nobody else wanted, STK V960, and now integrating into the Hitachi world the methods of storage replication was an after thought. The STK V960, while older an *unwanted* at least offered a snapshot feature with a VM interface for controlling replication, and Hitachi is telling us (short of experiment yourself with ICKDSF on a full volume level) none of their replication products have a native VM interface - specifically, we desire access at the minidisk level vs. full volume. We basically use full volume 3390 emulation, but reserve CYL 0 for unique volser, such that the replication involves zOS shared DASD full volume dumps of snapshot target volser's, and zVM uses internally for cloning guests (vs. DDR's). Question for LIST: Is anybody out there using a Hitachi USP subsystem for the zVM storage, and if so, how are you handling volume replication? Hitachi indicated that they had *heard* that some customers were running zOS as a guest machine under zVM, but this seems impossible to justify for us in that the reduced VM license cost for IFL would no longer be an option, plus the zOS licensing to boot. Any ideas or experiences out there would be appreciated for consideration.

Re: FW: IBM saves $250 million consolidating Linux servers on to mainframes | NetworkWorld.com Community
Just curious, because I don't know how the hardware works, if 30 mainframes do the work of 3,900 servers, that means 1 mainframe does 130. Does that mean that potentially that 1 mainframe has the equivalent of at least 130 network cards? I can see how most of the hardware is virtualized, but the networking I don't quite see, yet. How does that part work? Lindy: You can have up to 24 OSA-Express cards in a System z9 EC (each with 2 physical ports). Each port can have up to 640 TCP/IP stacks (Linux images). For more information see: http://www-03.ibm.com/systems/z/networking/features.html However, when running large numbers of Linux images, you normally run these under z/VM. z/VM has a built-in Ethernet switch (in software) so you can have the Linux images connect to one or more VSWITCHes which connect to the physical OSA-Express ports. Also, on the z9 family you can use a function call Link Aggregation to use multiple physical ports through the VSWITCH for performance and availability.

Here is the official IBM position on this. I wrote these rules so I know where they came from. I won't go into the background here, but if you are at SHARE in San Diego, come and ask me for the gory details. Again these rules apply only to IBMers, for others they are guidelines. - 'Linux on System z' refers to the operating environment of running the Linux operating system and applications on System z (including eServer zSeries) servers. This was formerly called 'Linux on zSeries'. - 'Linux for System z' refers to the Linux distributions available from Linux distributors that run on System z (including eServer zSeries) servers in 64-bit mode. This was formerly called 'Linux for zSeries'. - Note that 'Linux for S/390' may only be used to refer to the Linux distributions available from Linux distributors that run on System z (including eServer zSeries) servers 31-bit mode. - Linux on z/VM refers to the operating environment of running the Linux operating system and applications under the z/VM hypervisor.

Re: XEN vs zVM
No, Xen assumes an Intel architecture. I (personally) don't think Xen will ever be extended to work on a mainframe. Given the very low cost of z/VM, I would suggest you just go that route Mark: Actually Xen supports (at least in development) x86, x86-64, IA64 and POWER. However, I agree that I can't see it being ported to z/Architecture. The development cost would be very large, and for a relatively small market. The only reason it is coming on POWER is that IBM has contributed much of our hypervisor code for POWER to the Xen project. Same with IA64 where HP has contributed code for IA64 that they wrote for partitioning.

Re: WAS on zAAP versus pSeries
IBM says zAAPs are the same price as IFLs, but they are not. You don't license software for zAAPs but you do for the IFLs. zAAPs, zIIPs, and IFLs have the same HARDWARE price. You don't pay for software on zAAPs and zIIPs, but you do pay for software (but as open prices, not z/OS prices) on IFLs. I also recall somewhere, where it was stated that if you had the processing to totally use an engine, that only about 40% would end up on the zAAP with the rest (non Java code) would be on a standard or IFL engine. But all that depends on your mix of Java vs non-Java code. You are confusing zAAPs and zIIPs. It is possible that up to 100% of your Java code running on z/OS could run on a zAAP. However that is up to the Workload Manager (WLM) which may decide that running some of the Java code on a CP will give better performance. However, for zIIPs WLM will ensure that no more than 40% of the DB2 workload gets offloaded to the zIIP. DB2 on z/OS is of course priced on capacity so IBM SWG wants to make at least 60% of what they were making without a zIIP.

Re: WAS on zAAP versus pSeries
Does anyone have an idea how running WebSphere Application Server on z/OS on a System z zAAP would compare to running it on x number of processors of a P595 at 1.9GHZ? Any good guesses on the value of x here? What if it was an IFL instead? Bob: This is a hard question to answer. A z9 EC processor runs at 1.75GHz but you can't really compare z9 GHz to p5 GHz (totally different chip designs). An IFL, a zAAP, and a CP run at the same speed (unless you have a sub-capacity CP). Of course it really depends on the total application. If you are doing a lot of I/O (say a database back-end), then a z9 will probably outperform a p5 with the same number of processors. If the application is compute bound (not likely), the a p5 will probably outperform at z9. z9 virtualizes (in the general sense of running multiple concurrent workloads) better than any other platform so if you are running lots of WAS images z9 will probably perform better. You really need to get IBM WAS people involved who can look at your workload and give you specific advise. Of course, talking to other customers who are running WAS on z9 is a great way to get an idea. There are lots of customers running WAS on both z9 and p5 so talk to your IBM rep to set up some calls with other customers!

Re: what is the conversion from mips to Ghz or back
I've been asked this question and have looked around but can't seem to find an answer. Mace: As others have noted, this is a meaningless comparison. It is even meaningless on Intel and RISC (POWER) these days. The cycle time of a system has less and less to do with performance. A POWER5+ machine running at 1.9Ghz has dramatically greater performance than a POWER4 machine running at 1.9Ghz. Not only does processor design affect performance, but total system design. Something as basic as the size of the level2 (or even level 3) cache will make a huge difference. And of course with System z, the architectural differences (things like the SAP I/O processors, all the PowerPC procesors used in the I/O subsystemm, etc.) make a huge difference for certain workloads. We often see on this list people comparing performance of a compile on a 3Ghz x86 system to a 1.7 Ghz z9 EC system. Of course the x86 will be the z9 EC as the compile will run in memory on the x86. In real world business applications, they do not run all in memory and there is a large I/O component.

Re: PVCREATE Problem
Here is what I found in a casual Google search: DASD device driver 2 3 S/390's disk devices (DASDs) are managed by Linux via the DASD device 4 driver. It is valid for all types of DASDs and represents them to 5 Linux as block devices, namely dd. Currently the DASD driver uses a 6 single major number (254) and 4 minor numbers per volume (1 for the 7 physical volume and 3 for partitions). With respect to partitions see 8 below. Thus you may have up to 64 DASD devices in your system. 9 10 The kernel parameter 'dasd=from-to,...' may be issued arbitrary times 11 in the kernel's parameter line or not at all. The 'from' and 'to' 12 parameters are to be given in hexadecimal notation without a leading 13 0x. 14 If you supply kernel parameters the different instances are processed 15 in order of appearance and a minor number is reserved for any device 16 covered by the supplied range up to 64 volumes. Additional DASDs are 17 ignored. If you do not supply the 'dasd=' kernel parameter at all, the 18 DASD driver registers all supported DASDs of your system to a minor 19 number in ascending order of the subchannel number. 20 http://www.mjmwired.net/kernel/Documentation/s390/DASD Ray Mrohs U.S. Department of Justice 202-307-6896 -Original Message- From: LINUX-390@VM.MARIST.EDU [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Friday, October 20, 2006 3:15 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: PVCREATE Problem Importance: Low I hate to say this, but if it is in /proc/dasd/devices, and /dev/dasdbm1 exists, and you are under 256 PVs for this VG, then I would look at installing some maintenance.

Best Swap Disk Strategy?
My past installations have used 4 same-sized v-disk areas with ascending priorities.

Would it be something as simple as a response time test to decide which swap algorithm to use? In a perfect world I'd like to simply give Linux one chunk of v-disk, and let the OS figure out how to use it. As server apps grow it gets riskier to mess with the fstab to add more v-disks, and we also end up with a bunch of non-standard disk layouts unless we plan well in advance. In the mean time, I think I'll standardize on 3 progressively sized v-disk addresses starting at .5 RAM, with no DASD swap. Thanks. Ray Mrohs U.S. Department of Justice 202-307-6896 It would need to be something that works for all platforms, not just for our virtual disks. The idea is that by using fresh slots you have a better chance to build long chains of adjacent blocks in a single I/O operation. If utilization is low enough, the moving cursor is an easy way to do that. With vdisk we're willing to take the overhead of many small I/O operations because the device is already fast enough (especially when your driver can exploit synchronous I/O completion). -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
Re: zLinux User Passwords on console
Given the available options I would vote for allowing no-password logons to Linux via the console. Because: - Recording passwords is bad policy. Anyone who sees a console or console listing can then use the discovered passwords elsewhere. - Depending on keyboard mapping and special characters used (# ^ [ ]), logon to Linux becomes difficult or impossible via the 3215. - Access to the console can (should!) be restricted by regular VM security or ESM, the only possible problem being that some sites require 8 character upper-lower case passwords for their UNIX-type systems. Ray Mrohs U.S. Department of Justice 202-307-6896 1) For Linux on Z, there is no legitimate reason to be using the console for anything but emergencies that have broken network access to the guest. ssh with keyrings and sudo are for normal maintenance and operations access. If the server is so horked that you need the console, you DEFINITELY don't want J Random Luser messing with it. In that scenario, the people who will be working at the console already HAVE the root password or an equivalent security token and can do as much damage as they like. You aren't improving the security of things any by requiring the extra login at the console. 2) You have a authentication method as strong as the Unix login already in place (the VM userid login), assuming that you have decent password policies in place already for the VM side (and if not, why not?). 3) You can audit the living heck out of the VM login with an ESM, and even without one, CP does some fairly decent logging that's really, REALLY hard to circumvent. 4) LOGONBY can be selective -- no need to give them access to *everything*.

YOU and Missing Installable Patches
We have a local YOU server and several vservers in a zVM, all running SUSE9. On some of our vservers when running Yast Online Update (YOU) pointing to our local YOU server, some candidate patches (e.g patch-10747) are missing in the list of installable patches. I know for a fact that the YOU server has the patch available. It is inconsistent; some of our similar vservers do have it listed when doing YOU. The net effect of this is SPident is now reporting NOT uptodate. Maybe related to this problem is: in the online_update help, something is mentioned about patch default selection algorithm. What exactly is this? Thanks for any help.

Re: SLES vs RHEL
There are THREE different ways to acquire Red Hat RHEL or Novell SLES from IBM. 1) IBM offers both as pre-loads on all our servers EXCEPT System z. (Hard to do a pre-load with System z as there is no internal disk!) Normally with this option, service comes from the distributor. 2) IBM offers both via Passport Advantage for all our servers, including System z. Normally with this option, service comes from the distributor. 3) IBM offers both via IBM Global Technology Services (GTS) in conjunction with a service agreement where GTS provides the service. Also, IBM offers IRES for the Point-of-Sale market (retailers) which includes Novell SLES and service from IBM.

Re: SLES10 GA
From: Levy, Alan [EMAIL PROTECTED] Does s390x mean that they only have a GA for the 64 bit version of sles 10 ? What about the 32 bit version ? Alan: There will be NO further 31-bit (32-bit) distros (the s390 versions) for the mainframe. IBM announced months ago that from now on only patches for the s390x (64-bit) would be made available for new Linux kernel levels. Thus, both SLES10 and RHEL5 will be 64-bit only, but they will support 31-bit applications.

Re: Websphere Information Integrator
Just out of curiousity, how much effort is generally involved in porting an application such as this to z? Is it just a matter of building it from source on z and making sure everything works? (Not that even that is in any way a small efford.) Or are there generally code changes required as well? Frank: Generally any application which runs on Linux on x86 will compile and run on Linux on z (or Linux on POWER) with few or no changes. The exceptions are those with hardware dependencies (these are often seen in systems management type of software which gets down into the kernel). The real effort in any port is in two areas: 1) The installation tools (you would be amazed at how many Linux apps, even server apps, are dependent on a GUI install!) 2) TESTING. Testing can often take as much as half the development cycle and this is pretty much repeated (or should be) on every platform.

Re: SLES/SLED10 RC Software Available
Sounds to me that since IBM withdrew marketing for S/390 architecture, the software vendors for the Linux on the mainframe drank the marketing kool-aid and are only supporting hardware that is supported by IBM. James: No markting kool-aid here. Since IBM is not supplying patches for the 2.6.16 kernel for anything other than 64-bit on z, the distros really don't have much of a choice. However, I expect that the distros really don't want to support 31-bit S/390.

Oracle and Linux under z/VM
Hello, I'd like to know if there's anybody using Oracle under Linux and z/VM. Our situation is: -Oracle 10g - SuSE 9 - z/VM 5.1: zSeries 800, 2 IFLs, 4.6 GB of central storage, 1,5 GB of expanded storage, 6 ESCON channels, DS/8000 storage. - At this moment, there's another VM guest with 1 GB in size. The database is 176 GB in size, used for datawarehouse. The common accesses are transactional (short term requests) both in queries and updates. The results of our performance tests are bad (in words of our DBA, because my problem is that I have no knowledge of Oracle, so I only know what my DBA tells me). What I can observe from Performance Toolkit is that we have a high rate of pages moving from central to expanded, and from expanded to central, causing a high CPU use. At this moment, I'm aplying fixes UM31411 and UM31485 because they are commended for this kind of problems. Any help would be welcome, because I have tried everything, and I don't know what could be the problem. http://webmail.wanadoo.es.

Hello, I've tried some messages before, but I don't know if they have been blocked. I have a very simmilar situation that the one described in other notes. We have zSeries 800, 4.5G and 1.5G expanded, and we have a guest SuSE 8, 2G in size, Oracle 10g. The SGA in Oracle is fixed to 1.7G (this is the size with better results at the moment). We have done many tests: If we reduce the size, I/O increases and we have a poor response time. If we increase the size, CPU is at 100%.

Re: e: LVM fragility?
One issue is in a default SuSE9 install, the dasd= is not used in the parmfile. If you add DASD and activate it via yast, the parmfile is not touched; yast will happily adds the new DASD to /etc/fstab until the /dev/dasdXX changes and then it won't boot. To add confusion, SuSE9 also adds: /dev/disk/by-path/ccw-0.0.0309p1 - ../../dasdj1 which appears persistent and mountable. But then if you add DASD in the middle, the link to /dev/dasdXX is not maintained and is wrong. --- Ismael Ifurung Tel. (916) 739-7689 Health Human Services Data Center Fax. (916) 739- P.O.

Mounting reiserfs in read-only
I have a minidisk with a valid reiserfs file system. In a running SuSE9 system, I CP link to the mdisk, read-only, activate it and attempted a mount; the mount fails. It seems like it wants to replay the transaction, even for a read-only. I was able to mount successfully the same reiserfs mdisk in read-write mode. Also, I was able to link (read-only) and mount successfully a different mdisk with ext3 filesystem. How do I mount a reiserfs mdisk with a VM read-only access?
