Dang Printer
Ok, I understand this is old and everyone wants to know why. Try to forget that and recall how you defined that IBM 6262 printer 20 years ago. Here's my situation: CHPID PATH=(CSS(0),EA),PARTITION=((P1),(=),REC),PCHID=1EA,* TYPE=CVC CNTLUNIT CUNUMBR=EA00,PATH=((CSS(0),EA)),UNITADD=((00,001)), * SHARED=N,PROTOCL=D,UNIT=4248 IODEVICE ADDRESS=EA0,UNITADD=00,CUNUMBR=(EA00),TIMEOUT=Y, * STADET=Y,UNIT=4248 I've tried SET RDEV to 3211 and to impact_printer with no joy. I saw an old post from John Fransicovich that says you have to have an image library for an ibm 6262 model 22, tried IMAG4248, still no joy. The printer won't come online. Depending on the RDEV, I either get unable to identify device 0ea0 dynamically or a simple no channel paths is available. If anyone has such a config, can you look over my iocp definition and let me know what your set rdevice is? Thanks!! Mary Anne
Re: Dang Printer
Thanks Kris, I think we're getting closer. We changed the definition from EA0 to 00E, so that we don't have unitadd=a0, we have unitadd=0E. We got it online and were able to attach it to mvs, but it's getting errors. But we did get an intervention required so at least it's starting to talk. CE is here running diagnostics. Thanks very much for the assistance. I'll let you know how it goes.

Re: Dang Printer
I hope not, have no idea what a loadbuf is. :) We did get output. We switched it 00e, but of course there was already an 000e in the IBMDFLT profile, so had to add a new profile without an 00e, then att the rdev to the guest as 00e, $addprt1, change the fcb, and were able to print.

Re: What we must do before we claim the zlinux server is in production stage?
Pretty good list, Tom, I would add: 1) Reporting for the auditors (racf violations, etc) 2) Get EREP running and be able to produce reports in case the CE's need them This includes the collection of erep data, of course. 3) Hopefully you already have a scheduler or vmserve to run nightly tasks. 4) If you have RACF, backup the db and practice restoring it. 5) Hopefully you've set up prop or something similar to catch important messages and act on them. Either clear up the problem or send an email to yourself about it. (Mailit is a useful tool for this) I had dozens of little rexx execs for stuff like this. Purge diskacnt's 191 files older than 90 days, etc. 6) If you have perfkit, make sure you are capturing console messages and doing something with them. Perfkit will check the health of the system based on your specs. But you've gotta be seeing the msgs.

Re: USER MDISK and DIRMAINT Question
Valerie, I can take a couple of these questions, hopefully others will jump in on the ones I can't answer. On the 'END' statement, I found that documented for the diskmap utility as well, so I changed all mine to the actually cylinder address. In the long run I found it easier to be able to see the size of the device in user direct. (IE, oh, this linux has three mod 27's and a mod 9). Our dasd numbering system didn't have that info, ymmv. IE, you may know that the 1000 string, for example, is all mod 9's. Mine was interspersed, so having the end cylinder was a quick way to find that out. On the 191 thing, I've done both ways, the 1 cylinder 191 on the linux 200 volume and on another volume. Either way really works fine. Only thing I found was if you have multiple lpars, and, despite people saying 'we won't be moving linuxes back and forth to different lpars', of course six months later they're moving crap all around. So it was helpful to have the 191 and the 200 on the same volume. If you have a volume full of 191's, and you want to move the linux to a different lpar, you have to either copy the 191 to another 191 volume or create a new one on the new lpar. In my last shop, we had a mod 3 for non-IBM-supplied userids (ie, mine) and a mod 3 for linux 191's. We kept that separate from the res pack for ease of migration. But I'd be interested to hear what others are doing in hopes of getting a consensus.

As I have been searching the list archives for answers, I will start by saying I can identify with a comment made on this list back in February: ...go to a new z/VM shop that has z/VM just to support virtualized Linux and watch as they attempt to get DIRMAINT and RACF installed and configured, and then begin to use it. It isn't pretty. Haven't started on the RACF yet --- I can hardly wait! (you may all want to come and see the show!) Some pressing questions I have: I finally found the DIRMAP utility to map the minidisks. What I am seeing on my 5.4 system is that the use of the word END for end-of-volume and the resulting LENGTH seemed to get translated in my conversion from USER DIRECT to be 3390-01 numbers, not 3390-09 as I am using, at least on the report it puts out. (This is true for th $PAGE$ entry for the PAGE volume, the $SPOOL$ entry, and MAINT 0122 entry for the SPOOL volume, and the MAINT and SYSDUMP1 0123 address entries for the RES volume). Is this just a glitch with the report or do I need to get rid of END entries and/or code something else somewhere that I am missing? I would like to create some Real USERIDs in the style required by Security. I am looking for a best practice here. It would seem to me best to place non-system user-defined stuff (to use a technical term) OFF of the RES volume so it easily carries from one release to the next. I have noticed that the redbooks, etc. that go through creating Linux guests seem to put their 191 mini-disk on the volume defined for Linux use. It would seem to me that possibily these and definitely any admin CMS disks should go on what we would call on the z/OS side a User volume (maybe equal to a Work volume in z/VM terms?) What is best practice/most used for CMS disks? Also, can someone point me to (or give) a quick sample of what is needed if I use LOGONBY both in the logon TO and the BY definitions? Thanks to all of you. Also, I have no idea about carrying forward the DIRMAINT files at this point (let alone where they really are). How are these usually handled when changing releases?

It's very hard to constrain a system to swap this much, this was in the lab pushing limits not normally pushed. With z10 IFL significantly faster, swapping to vdisk would not be a significant cost. The largest performance problem facing us today is storage, as IBM Software Group has decided to put polling back into their applications (remember the hertz timer in Linux we eliminated in 2003? - it's back courtesy of IBM applications). With polling, the over commit ratio you can attain is now about 1.5 - so reducing Linux storage sizes and causing some swap means more Linux servers per installed storage. Robert J Brenneman wrote: Just a guess till the experts chime in: Linux disk I/O activity requires more CPU time than traditional Z Operating systems - so when one guest starts driving 5000 I/O ops per second to the swap device ( FBA mode vdisk in my case ) that in itself consumes a big chunk of CPU. Then there's the additional time spent in the linux kernel itself deciding what needs to go out to swap and what needs to come back in. let me re-emphasize this is a guess - I'd like to know the answer to this too.
Volumes across channel extenders
Hello all. While we're on the subject of DASD today, I finally got my chpids to access the production dasd from the D/R machine z/VM 5.4 lpar. I tried to accept a big range, and maint hung up. I waited a half hour, then tried to force him. No joy. So I removed the dasd from the not accepted list, and IPL'd. The IPL took 5 minutes to get to the SALIPL Screen. When it came up, I tried to vary on a range of about 15 devices. Again, hung up maint. Wait 1/2 hour, IPL. Tried to vary on one device, and it worked! So I tried the next one, hung up my ID, and it's still sitting there 45 minutes later. Any ideas? Some sort of MIH setting? The SDMPlex is fine...not a whole lot of activity on these devices. I have 2 chpids online. I understand it's going to be slower, but this just won't work. :) Thanks all! Mary Anne

Re: I/O Overhead - z/VM versus VMWARE
I think you need to compare Linux in a z/VM LPAR versus Linux Native, and determine if one has more i/o overhead than the other. I think the answer is going to be 'minimal'. As someone said, and I have observed, my CP%CPU runs at 2-3%. As for MDC, I've been curious about that lately. About a week ago, I turned off mdc for a highly active volume, and it seemed to me that resp increased rapidly and markedly. I quickly turned it back on. So I tried just now, for fun. I took the highest activity volume in a large system, and turned MDC cache off. Here's the info at 5min intervals: I/O RateResp 127 3.0 MDC ON 86.5 6.5MDC OFF 69.6 9.2 102 4.9 122 3.3 93 3.5 11.7 12.3 At that point its activity seemed to decrease. So I guess my test is shot. :) MA On Fri, Oct 31, 2008 at 8:49 AM, Rob van der Heij [EMAIL PROTECTED] wrote: The comparison is already complicated because of different terminology. For example what we consider the overhead of I/O Is that in CPU resources, memory or I/O resources? A Linux system for example use a cache to avoid I/O, but that means there is memory overhead for I/O. And when the page cache is very large, there is also CPU overhead in managing that cache. Depending on the cache hit ratio and the disk response time, the overhead may result in faster response. And who would measure that on VMware? When talking to people from the other side it seems that I/O overhead is sometimes the measured throughput of an (assumed) I/O bound application, running either on VMware or native. To me such an interpretation has more questions than answers. But VM people tend to look at the T/V ratio of a virtual machine running such an application. That's not entirely fair because it also includes the cost of security, performance instrumentation, error recovery, etc. If a virtual machine wants to do I/O it may require paging to make room for the new data - is that I/O overhead? In general, I don't think that the difference in I/O performance is a motivation to run in LPAR rather than in a virtual machine. Before 5.2 we had the 2G issues that affected many installations. z/VM 5.3 addressed some more of these issues. One factor I do know about is MDC: many new workload does not exploit it as much as we used to do, so it sometimes good to consider not spending the resources on that. One of the factors that influences virtual machine I/O is the extra latency that comes with running multiple virtual machines. While this does not impact the overall throughput of the configuration, it does affect the maximum single thread throughput. That's what makes benchmarking complicated in this environment. QDIO (as used for OSA devices and FCP) is meant to address this latency issue. Under proper conditions this allows the channel to drive the I/O operations without waiting for the virtual machine to be dispatched and issue the next SSCH. This does have its price though, the CPU usage is higher than with ECKD I/O, so if you're CPU constrained the I/O might become slower.

Linux guest 191/200 disk question
Hello all. We're bouncing around an idea to change the way we allocate Linux guests. Currently, we have a mdisk that has all of the Linux 191 disks on. We then have separate 200 disks (mod9's). We're thinking of combining the two, such that we have a 1 cylinder 191 mdisk, then 10015 cylinders for the 200 disks. This would allow us to move the linuxes from one lpar to another as needed. It would also make them more self-contained. We're facing a dasd upgrade in the near future, and this would make that a little easier. Other than the fact that the 200 disk is backed up by TSM and the 191's via MVS's FDR, can you guys shoot some holes in this theory? Let me know if you see any other problem areas that I haven't thought of? Thanks! MA

We now have 5.4 fully deployed and it has been the most trouble free upgrade of them all.

http://biz.yahoo.com/ap/080226/ibm_new_mainframe.html?.v=5 AP IBM Rolls Out New Mainframe Tuesday February 26, 7:36 am ET By Jordan Robertson, AP Technology Writer IBM Rolls Out New Mainframe, Reflects Company's Focus on Data Center Costs SAN FRANCISCO (AP) -- IBM Corp. rolls out a new mainframe computer Tuesday boasting a 50 percent performance boost and dramatically lower energy costs than its predecessor. The new System z10, with a starting price at about $1 million, comes as IBM focuses on lowering the price tag for running its storied line of data-crunching workhorses. The Armonk, N.Y.-based company said it designed the new machine to help companies and government agencies that rely on mainframes -- usually for critical data processing such as bank transactions or census statistics crunching -- save money on energy bills and better handle a flood of Internet information. The size of IBM's investment -- the company spent five years and $1.5 billion developing the new mainframe -- also underscores its commitment to the long-term viability of the mainframe and efforts continue adapting the decades-old product line to the Internet age. For years some IT experts predicted the demise of the mainframe, bulky and expensive machines that face competition from smaller, less-expensive servers. But IBM says mainframe revenue is growing, rising in 5 out of the last 7 quarters, thanks in part to interest from emerging markets like Brazil, China, India and Russia. IBM says it incorporated a number of technological upgrades into the new machine to appeal to cost-conscious companies looking to consolidate the number of servers in their data centers. The z10's capacity is equivalent to 1,500 servers based on the popular x86 design, IBM says, though it has 85 percent lower energy costs and takes up 85 percent less space than the batch of x86 servers. The new machines also boast more processing horsepower, using 64 processors compared to the 54 processors used in its predecessor, the z9. Those chips are better at multitasking -- the new machine is IBM's first mainframe to use so-called quad-core chips, or microprocessors with four computing engines on a single slice of silicon. Adding cores to chips improves their ability to handle multiple tasks at once. Mark Anzani, a vice president in IBM's Systems and Technology Group, said the new machine has the reliability that mainframe customers expect but improves performance in tackling Web-based applications. The combination of two worlds in this one new machine will allow companies to really take a bite out of the complexity of the data center, Anzani said. Analysts said IBM's advances in chip technology and software are helping the mainframe stay competitive against lower-cost competitors. But they caution that because of price IBM still faces challenges in luring in new customers. While the high-end z10 starts at about $1 million, IBM notes it has mid-range mainframes that start around $100,000. Without IBM's ability to deal with the new workload as part of the mainframe environment, we wouldn't be seeing the return to growth in the mainframe, said Brad Day, a Forrester Research vice president. But this is definitely not a slam dunk -- the math still has to be there. The life-cycle-cost-of-ownership argument still has to be there.

IBM says it incorporated a number of technological upgrades into the new machine to appeal to cost-conscious companies looking to consolidate the number of servers in their data centers. The z10's capacity is equivalent to 1,500 servers based on the popular x86 design, IBM says, though it has 85 percent lower energy costs and takes up 85 percent less space than the batch of x86 servers. The new machines also boast more processing horsepower, using 64 processors compared to the 54 processors used in its predecessor, the z9. Those chips are better at multitasking -- the new machine is IBM's first mainframe to use so-called quad-core chips, or microprocessors with four computing engines on a single slice of silicon. Adding cores to chips improves their ability to handle multiple tasks at once. Mark Anzani, a vice president in IBM's Systems and Technology Group, said the new machine has the reliability that mainframe customers expect but improves performance in tackling Web-based applications. The combination of two worlds in this one new machine will allow companies to really take a bite out of the complexity of the data center, Anzani said. Analysts said IBM's advances in chip technology and software are helping the mainframe stay competitive against lower-cost competitors. But they caution that because of price IBM still faces challenges in luring in new customers. While the high-end z10 starts at about $1 million, IBM notes it has mid-range mainframes that start around $100,000. Without IBM's ability to deal with the new workload as part of the mainframe environment, we wouldn't be seeing the return to growth in the mainframe, said Brad Day, a Forrester Research vice president. But this is definitely not a slam dunk -- the math still has to be there. The life-cycle-cost-of-ownership argument still has to be there.
Re: Added central/expanded storage...
Brian, when you say 'bounced the VM lpar'...did you deactivate and activate the LPAR? Something we found that for some reason takes a lot of Xstore is VDISKs...do you use them regularly?

Re: Article: In Search of Mainframe Engineers
You know, I've been thinking about this and I just don't think I buy this article, or this hoopla that we've heard for several years about the aging mainframer and how to replace them and how scarce they are. I just don't see that many job openings for MVS or VM. And I sure don't see skyrocketing salaries, in fact IBM just cut salaries of a lot of mainframers 15%. Now that is supposed to be offset by overtime but those that I've talked to indicated overtime isn't allowed. Personally, I think this is just a way to get more h1b visas approved. If MVS or VM sysprogs were such a hot commodity, salaries would be rising. Thoughts? MA

The path was varied off from all devices and the chpid varied offline. The chpid was then taken offline at the HSM and the part replaced. When the chpid was brought back online at the HSM, the ensuing device reconfiguration interrupt apparently caused all 4096 devices to be brought online. Unfortunately, only 365 of the devices were online when the hardware activity started. The remaining devices are in the Devices_offline list in the SYSTEM CONFIG file and are not supposed to be online to VM. In this particular case, only the one path out of four was affected by the hardware problem. I cannot put the devices in an ignore list because it is sometimes necessary to make one of them available to VM. From the description, it does not appear that making them not_sensed would help. In fact, it would probably make the occasional need to make a device available more complicated. Is there any way to have the devices stay offline in a situation like this? Regards, Richard Schuh

AUTOLOG2 brings up all the LINUX guests, which need to be restored first. If needed, the individual LINUX guests can be forced off. The TCPIPDR stack masquerades as the various gateways that the LINUX guests use and forwards everything to the external router IP used at DR. The DR I/O configuration leaves out the OSA addresses in use at the home site and includes a new OSA address for use only by TCPIPDR. This prevents the VSWITCHes from passing traffic directly to an OSA, allowing the TCPIPDR stack to route all the traffic. This setup means we don't have to update IP stacks.

Re: D/R Code
Ron, that's fine for DR tests, but we need to be able to come up automagically if we're all gone in a real DR, so our main 'goal' is to run as if it's a real DR and get the whole way up with no intervention. So I'll have autolog come up, it will fail, and in a test I'll force the linuxes and tcpip, then start autolog with a parm. That way I have intervention on a test but not in a real dr.

Re: IBMVM Digest - 5 Jan 2007 to 6 Jan 2007 (#2007-6)
You can use z/OS DFDSS to backup the z/VM and z/VSE dasd but (IMHO) it is not a wise solution because of the restore considerations. With enough practice you could make it work. What are the restore considerations? We use this all the time, backing up and restoring a vm system from z/os, with no problems whatsoever. Do you mean considerations for VSE?
Re: Agency Recovers From Computer Break-Ins
By sensitive, perhaps they meant classified. The article stated that at was an unclassnetwork that was hit. So no classified info was stolen. So what info was stolen? We don't know yet.
