We run it on all of our platforms and do manual scans everywhere since it provides more control than the scan groups. As far as z goes, we use Operations Manager to kick off a few scans at a time so as not to bog down the LPARs and we only do it monthly. The scripts also knows about which filesystems to scan and which ones to bypass and adjusts tlmagent.ini before the scan. I know this can be done in the server itself, but it's just easier to let each platforms script manage it since the respective groups know what's happening on their servers the best. Another thing we do is drop the cache on each server after the scan completes. The first time we let the ILMT server do the scan automatically, the person that set it up put all of the zLinux servers in one scan group and they all kicked off at once. z/VM paging went totally bonkers due to memory overcommit (3 to 1 if I remember correctly). I maintain the ILMT server now. :-) Also, in case you want to manage it via scan groups, check into the lmtcli.sh command as it will allow you to automatically assign servers to different scan groups (and a lot more). I have a script that runs daily and checks for anything in the DEFAULT group (we assign all new servers to DEFAULT) and reassigns them to the correct groups using the command. Since we do manual scans, the scan groups don't do much for us except for reporting and I have a script that runs monthly to check for invalid/missing scans and emails a report to the correct group. The notifications built in to the ILMT server don't really provide a way to do that (not that I could find anyway). Anyway...just some tidbits on how we roll. :-) Leland And no, I never did figure out exactly how to configure the capacity values so if you do I'd be might grateful if you'd pass on the info.

Pat, thank you! Would love to see a copy of your install script.

IBM Sterling Connect:Direct for z/VM Announcement
Don't know if you all saw this. I was hoping that when IBM bought them, they might enhance the VM product. Instead, they killed it. Sigh. -- The purpose of this email is to advise you of a change in status of IBM Sterling Connect:Direct for z/VM. This information is date sensitive. If you are not currently responsible for these products within your organization, please immediately forward this email to the responsible individual(s). As the e-business and information technology landscapes are changing, Sterling Commerce must adapt its offerings to match current requirements. We are therefore announcing the phased withdrawal of some of our current products and services. Details: - The decision to end service of IBM Sterling Connect:Direct for z/VM was made as a result of the product's dependence on the IBM VSE/VSAM module for z/VM which is no longer supported by IBM. - End of Service - 12/31/2012 - The product will no longer be supported by IBM You will have two choices: - Migrate to another IBM Sterling Connect:Direct platform by the End of Service date. - Continue using IBM Sterling Connect:Direct for z/VM beyond the end of service date without continued IBM/Sterling Support. More information is available on the Sterling Commerce Customer Center site linked here: Connect Products End of Life Migration/Entitlement Page (Please note, you need a username and password to enter the site) Your IBM sales representative can help provide you with additional information on IBM/Sterling offerings.

Good security practice I believe ;) So there's not anything I can offline that isn't already.

Re: RMSMASTR and shutdowns
You can. I guess that is an advantage... very minimally though. Authorization to mount comes out of our tape product and its ESM rather than the config file so it changes very, very rarely (wait, shouldn't auth come from the ESM anyway and not its own private auth file :) . The device files update require you to recycle RMSMASTR anyway, so give him and r/o link and I can update it before the recyle anyway. So the pain outweighs the advantage.

(Yes in that I agree with Marcy). When I installed RMSMASTR I was concerned about what might happen to my config statements when the next z/VM release, or even maintenance, rolled around. Would IBM alter the config file because an RMS developer wanted to include a new feature (yeah... right), would my file be lost/overlooked during the migration (a significant chance)? So while wondering what possessed RMS development to put the config file into SFS in the first place, I created a new SFS server named something entirely unlike anything IBM ships, placed the config file there, and pointed RMSMASTR to that one. Since the server was one of our own, it never got changed when IBM applied service, and was never left behind during an upgrade. Marcy is 100% correct (especially with the SSI SOI).

RMSMASTR and shutdowns
Out of the box, RMSMASTR behaves very badly on a signal shutdown of your VM system. We have to use this to mount tapes in the VTS. RMSMASTR has files in VMSYSU: and VMSYS:, which both use signal shutdown by default. RMSMASTR hangs up the shutdown of VMSYS: until your system default shutdown time is up. That could be very long time. Or not, but not getting all the way down has required us to need FORCE starts on some systems on occasions, so a shorter time isn't even helpful. So we wrote our own SHUTTRAP thing to issue a DMSMSRM STOP command. This doesn't reliably work either. It's very timing dependent since this service machine gets the signal at the same time as VMSERVR and VMSERVS and if they beat it, the DFSMSRM STOP says not authorized (the auth file is in VMSYSU:) I opened a PMR once upon a time and it was rejected. We're trying to get things automated enough so that operations does nothing on the VM side and GDPS which signals the processor controller to shutdown the LPAR is sufficient. Does anyone else think this should be considered a defect? We'll probably work around it by one of these things 1. Use CA VM:Operator to FORCE RMSMASTR upon message HCPSHU6018I The processor controller has sent a shutdown signal with a timeout interval of 300 seconds 2. Use FORCE if dfsmsrm stop fails with DGTUDR2016E User not authorized to issue this command 3. Put NOSHUTDOWNSIGNAL in the parms file for VMSERVS and VMSERVU. Not nice to them, but what would we lose? Not much I think. Marcy This message may contain confidential and/or privileged information.

It's running Linux. GDPS proxy server for hyperswapping. I'm OK with him taking 30 seconds - the whole 4:30 is attributed to RMSMASTR (see other email) It's the 1:56:51 - 1:56:19 - 32 seconds (or 33 it reports ) that exceeds what SHUTDOWNTIME is set to in this case.

Re: Question on SHUTDOWNTIME
Ah, I wonder if it is a function of number of devices! Prod has 1800+ DASD vols now, each with a PPRC secondary - so approx 3700 addresses. That would explain why our tiny systems here have seen it too - they have access to the whole farm. We'll see what Endicott says tomorrow I guess.

Re: Dynamic Activation of New IODF
Is z/OS in another LPAR on the same box? If so, it's easiest just to let them do it and VM will just see the changes. Marcy From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of Michael Coffin Sent: Tuesday, June 07, 2011 8:15 AM To: IBMVM@LISTSERV.UARK.EDU Subject: [IBMVM] Dynamic Activation of New IODF Hi Folks, For many (many) years, when it comes to managing the IOCDS I simply hand-create an IOCP file, use IOCP with WRTAx to store it, and do a POR to load it. If the changes are needed immediately, I use CP commands to manually define the new hardware. Our z/OS guys want to manage the IOCDS and be able to dynamically activate an entirely new IODF file (created either on their system or using VM's HCM/HCD). I'm unclear as to when/how the changed IODF file becomes dynamically available to the running z/VM system. Let's say I store the new IODF using IOCP with WRTAx to store it, and then execute SET IOCDS_Active to mark it as the active IOCDS - according to the doc for SET IOCDS_Active this simply marks the IOCDS as active for the NEXT POR (and write-protects it) - but it doesn't look like the changes in the new IOCDS are reflected to the running z/VM system until a POR occurs. What am I missing here? Is it even possible to store a new IOCDS, mark it as active for the next POR AND have CP add/change/delete IO definitions by comparing the prior IOCDS with the newly activated one? -Mike

Re: zvm directions
Phil, I'll 2nd your opinion that 4 systems in the SSI is meager. I'm already in a quandary there with 4 prod systems and capacity planning asking where we put the next ones. So now I'm not sure if we step into SSI with all 4 or have to immediately start with 2 plexes. If two, we're giving up something. I don't see LGR as a load balancing solution at all. We will continue to use our F5 load balancers as well as the WAS IHS plugin for that effort. I see it more for a planned outage move for things you want to move away for a while without the reboot. 512M seems like a good next target given our 196's can do 3TB. We leave half for failover so that would mean we would do 3 prod LPARs on the box, with the 3 standby. That seems reasonable. Avoiding VMWARE type sprawl I think is a good thing :) We've just moved to the 10Gig OSAs and away from the LACP for a couple of reasons, so that is not as important to us. The cost of OSA ports IMHO probably doesn't justify VM developer time. Replication, large ECKD minidisks, zHPF (or any I/O related things to keep ECKD perf on par with FCP), are things that are important here. With the z196s being the fastest thing out there now, I see an avalanche of new workload coming. Sounds the same for you. (PS. I'll 2nd Marty's idea of getting involved in SHARE if you can!)

I am looking for your thoughts on the current direction of zVM in particular where development needs to be focused. I sense that z/VM 6.2 with SSI will ease the burden of medium to large shops in the area of multi-system maintenance, and hopefully will be extended beyond it's current meager 4 system max size, sooner rather than later. Given the difficulty in making any changes to production workloads I don't see SSI with Live Guest Migration (LGM) as a panacea to issue related to load balancing amongst lpars. Without more direct linux interaction I am concerned about the migration of workloads using dedicated fcp with or without NPIV as well as arp issues. The area I would like to see development is the utilization of the hardware some of us are lucky enough to have, the z196. With a machine that can be delivered with 3TB of memory(1.5TB on a z10), having a maximum size z/VM system of 256GB is very limiting. In reviewing presentations on memory limits, I have read comments that the system has been tested to more than 400GB central storage but no indication (statement of direction...rumor) that the current limit will be increased. So I am pushing for increasing the max z/VM LPAR to at least 512MB if not larger. Expansion of the link aggregation implementation allowing for shared OSA cards. In general I am focused on larger vm systems, so that is where I would like to see development. Phil Tully Viewpoints presented here are my own and not my employer's
Re: zvm directions
The tongue benefit is huge. Gotta keep up with them other guys ;) The other really useful case I see is in the dev/test environment. Say we want to get some good measurements from an app before they go production or to size them properly for their prod server purchase, but we have some pigs (uh, I mean very active developers writing code that is still in the early stages) skewing the results.

An excellent assessment, Marcy. :-) LGR was not designed to replace any application-level workload balancing solutions (F5). Those balancing solutions provide the needed HA in case you lose a VM LPAR unexpectedly. LGR will let you take back control of your VM LPARs. No longer will you need to get 15 application owners to agree on a time for you to take down and service the VM system. Their servers keep running and the application monitor dashboard shows green.

Depends on how far, right? You have to share DASD so PPRC distances apply. You probably need the same subnet so you need a consultation with your network folks.

An excellent assessment, Marcy. :-) LGR was not designed to replace any application-level workload balancing solutions (F5). Those balancing solutions provide the needed HA in case you lose a VM LPAR unexpectedly. LGR will let you take back control of your VM LPARs. No longer will you need to get 15 application owners to agree on a time for you to take down and service the VM system. Their servers keep running and the application monitor dashboard shows green.

I am looking for your thoughts on the current direction of zVM in particular where development needs to be focused. I sense that z/VM 6.2 with SSI will ease the burden of medium to large shops in the area of multi-system maintenance, and hopefully will be extended beyond it's current meager 4 system max size, sooner rather than later. Given the difficulty in making any changes to production workloads I don't see SSI with Live Guest Migration (LGM) as a panacea to issue related to load balancing amongst lpars. Without more direct linux interaction I am concerned about the migration of workloads using dedicated fcp with or without NPIV as well as arp issues. The area I would like to see development is the utilization of the hardware some of us are lucky enough to have, the z196. With a machine that can be delivered with 3TB of memory(1.5TB on a z10), having a maximum size z/VM system of 256GB is very limiting. In reviewing presentations on memory limits, I have read comments that the system has been tested to more than 400GB central storage but no indication (statement of direction...rumor) that the current limit will be increased. So I am pushing for increasing the max z/VM LPAR to at least 512MB if not larger. Expansion of the link aggregation implementation allowing for shared OSA cards. In general I am focused on larger vm systems, so that is where I would like to see development. Phil Tully Viewpoints presented here are my own and not my employer's
Re: Using EMC Clariion SCSI disk with Linux
I think you need the 3326. FICON Express8 10KM LX (FC 3325) All the channels on a single FICON Express8 10KM LX feature are the same type, 10KM LX. FICON Express8 10KM LX utilizes a long wavelength (LX) laser as the optical transceiver and supports use of a 9 micron single mode fiber optic cable terminated with an LC duplex connector. FICON Express8 10KM LX supports unrepeated distances up to 10 km (6.2 miles). FICON Express8 10KM LX (CHPID type FC or FCP) can be defined as a spanned channel and can be shared among LPARs within and across LCSS. FICON Express8 SX (FC 3326) All the channels on a single FICON Express8 SX feature are the same type, SX. FICON Express8 SX utilizes a short wavelength (SX) laser as the optical transceiver and supports use of a 50 micron multimode fiber optic cable or a 62.5 micron multimode fiber optic cable terminated with an LC duplex connector. Note: You cannot mix 50 and 62.5 micron multimode fiber optic cabling in the same link. For details about the unrepeated distances for FICON Express8 SX, refer to IBM System z Planning for Fiber Optic Links.

It makes sense that the switch isn't negotiating at all. When the optics/cables are mismatched, the ports can't get word sync and can't even start sending ordered sets to do speed negotiation. A quick google search says that long wave is supported by that switch: http://www.brocade.com/downloads/documents/data_sheets/product_data_sheets/5100-DS-04.pdf Media types 8 Gbps: Requires Brocade hot-pluggable SFP+, LC connector; 8 Gbps Short-Wavelength Laser (SWL); 8 Gbps Long-Wavelength Laser (LWL); distance depends on fiber-optic cable and port speed 4 Gbps: Requires Brocade hot-pluggable, Small Form-factor Pluggable (SFP), LC connector; 4 Gbps Short-Wavelength Laser (SWL); 4 Gbps Long-Wavelength Laser (LWL); 4 Gbps Extended Long-Wavelength Laser (ELWL); distance depends on fiber-optic cable and port speed I don't know why he would say that long wave doesn't exist. Maybe he really means that they don't have any long wave in that switch. Long wave optics are usually more expensive... Our Ficon Express 8 cards support both long and short wave.

Be sure your guest isn't dropping into the eligible list. That can look like a network problem. Issue ind q to see if it is there and q srm or consult your performance monitor.

Looking at the ethereal traces captured on the guest. During normal operation the keep alive Frames are being sent every 30 secs and the z/Linux guest responds to the poll with in 60 micro seconds. But few times we noticed that the frames were being delayed up to 25 seconds (total time from the previous poll is 30+25) after the router sends the poll frame to the time the Linux guest receives them. This is causing the keep alive timer ( 9 secs = 1 sec X 8 retries) to expire and disconnect sessions. The Linux guest eventually receives the frames including the retires all at the same but by that time the sessions are dropped the router. It appears that the frames are being buffered and are delayed by the guest receives them. We for sure know that the router is sending the poll every 30 seconds but some were some how the frames were buffered (?) for 25 secs before being delivered to the guest.

Re: z/VM z/OS sharing same DASD
I think you can say best practice is on a need to know basis. This is especially important for some industries :) You really can't say you have a security system in place if something else can get there without it going through that security system. Does z/OS *need* to access your disk? (maybe they do if you do backups from there) Does z/VM *need* to access z/OS disks? (we have some isolated volumes that z/OS writes and z/VM reads, so yeah, but only on a very limited basis) Both Richard and Scott are correct (of course!). We do it at a gen level. That's most restrictive. And of course if you are doing it with a gen, then by LCU makes most sense or screwing up LPAR access lists becomes what easier :) You have not made mountains. They do exist :) Richards performance example is another reason. VM's i/o characteristics are shall we say less friendly to replication needs than z/Os is and tracking down performance problems are definitely more difficult if more than one o/s is hitting your subsystem.

We have 2 (z10) CEC's, each with z/VM and z/OS LPAR's attached via FICON Directors to a pair of DS8700's. As currently configured all of the DASD is defined on common LCU's and all of the DASD is online to all systems. This makes me nervous but perhaps my fears are unfounded? My gut tells me that a better configuration would be having the VM DASD segregated onto dedicated LCU's and the rest of the MVS DASD on their own LCU's - and that the respective devices not be online to the foreign OS's. Due to other recent discoveries we have some DASD reconfiguration work ahead of us anyway and, if it's worthwhile, I'd like to pile on with getting the VM DASD to be isolated as part of that work - but at the moment I can't quantify to those that would do the work why.

Re: Supporting Dot.1q trunk in z/Linux
Marcy :) Your using a trunk port requires the vswitch to vlan tag the stuff sent over it. So say you have default vlan of 100 on the vswitch going out over it and your vswitch has that defined as the default. Then if the IP x.x.x.x is on vlan 100 then you don't need a vlan on the grant. If the IP x.x.y.x is on vlan 200 then you will need a VLAN parm on the vswitch grant. Like set vswitch vswitch1 grant Linux8 vlan 200. I kind of feel it's safer to always put a vlan number on any grant on a vswitch using a trunk port.

As such there is no hardware coupling facility. It's for development only, not production capable and distributed primarily to IBM business partners like us who develop third party software for mainframes. zPDT is essentially a VM environment and it does not offer a coupling facility either. zPDT is an excellent fit for our purposes, which is development only, but not very flexible or dynamic. So we run z/VM 5.4 on it and then several z/VSE and z/OS machines under VM. What we tried so far is dedicating a volume to a dummy guest, OBJDUMMY. Like this: MDISK A80 3390 DEVNO A80 MWV Then in each guest z/OS machine we put in something like this: LINK OBJDUMMY A80 A80 MW Is this safe? What happens if two developers open the same z/OS library dataset member on this A80 unit? Will the second one entering be denied in SPF? If not what happens if they both store their changes? We have been unable to find decent behavioral documentation in this regard. If the locking does not go down to the member level, we may set up VM's virtual coupling facility.

This is really more of a z/OS question than a z/VM question, but some z/VM facilities do (or can) come into play. I'll be the first to admit that I don't know a whole lot about the SYSPLEX environment, but I'm not sure what you mean when you say It [the z1090] has no SYSPLEX hardware. Do you mean, for example, that it has no coupling facility? I know that z/VM can create a virtual SYSPLEX environment between virtual machines. I've never tried to do it, but I've heard that it can be done. And I'm not sure but I don't think any special hardware is needed. But I could be wrong. Check out the manuals. Assuming for the moment that a virtual sysplex is not an option, traditional methods of file sharing between MVS systems, such as GRS, RESERVE/RELEASE, etc., can be used in virtual machines. You can define full-pack minidisks and have the guests link to them, rather than dedicating DASD packs to a single guest. By using V in the link access mode in the directory entry you enable virtual reserve/release. Make sure that the DASD is defined in MVS as shared dasd. hth -- .''`. Stephen Powell : :' : `. `'` `-

Do a vmcp q v dasd If it shows r/w and is still not working, log the guest off and back on. If it works then, that would indicate it is some kind of RH problem and Linux was confused.

Again, the console log would lead to the footprint of the perp that would tell all. Another fine way to handle the situation and allow some control would be to IPL the guest into CMS before starting the Linux guest. Set up the machine using the CMS profile and do your sanity checks there, then IPL the Linux boot disk when you know things will go well. Given our two CEC environment, and our history before going into CSE, we use this method to check that the image was last run on the current LPAR before IPLing the Linux image, to be sure that it can't be running in the other CEC. We had the same image booted on both systems at the same time once too often, destroying the image (i.e... Once) We use a read-only CMS 191 with a profile to perform this vital sanity check (for us) before allowing the Linux image to start. (In fact, all our linux images share the same 191 minidisk.) Checking the Linux disks to be sure they are RW certainly wouldn't hurt as well. It would be a simple task, especially if you stuck to a standard addressing scheme for all your images.

The context is some application software that's licensed by the speed of the CPU. Apparently, there's a big price difference (measured in millions) if the speed is over 1.5 GHz or so. I dug around on IBM's web site and found that z10's have a clock speed of 4.3 GHz and z196's have a clock speed of 5.2 GHz. I was unable to find the speed of a z9. I recall from the z10 announcement that the z10 had a major increase in speed. I'm thinking that the z9 was under 2 GHz. Does anyone know the speed of the z9, or where I can find that information? The glossy announcements of the z10 on IBM's web site have been replaced by glossy announcements of the z196. If it makes a difference, I'm interested in z9 EC, not BC. For this purpose, relative overall performance doesn't matter. The software price is based on the speed of the chip. If the price is also based on the number of CPU's, then any savings on the slower speed might be offset by costs for more CPU's. First, we need to know the speed.

Re: z10 and z/VM 6.1
Tested what upgrade path? There's an upgrade path?! Or maybe you are talking about running the 5.4 CMS under 6.1 CP or something like that? We're on George's page. There's nothing compelling in 6.1 for us. And we have a lot of new function in 5.4 available by SPE which is way easier to do.

Why would anyone go to a higher release that has a shorter expiration and not much more functionality? One extenuating reason is that IBM is more likely to have tested the upgrade path for release N from release N-1 than release N-2. This is somewhat of a special case (5.4 being the last release before a major architecture level-set), but the changes to 6.2 made public so far are going to be doozies, and you don't need another annoying thing to worry about while you're learning that stuff. I think this is one case where I'd put up a 6.1 floor system and run the 5.4 production system in a guest. If you have Linux guests, they're pretty self contained, it's going to be fairly easy to move them to 1st level quickly, and your CMS users (if you have any) can do testing with both environments easily. Also, 6.2 isn't that far off, so you could stay current and move from 5.4 to 6.2 also in a guest, staying supported all the time.
Re: z10 and z/VM 6.1
Well, if you had a new install on z10+ and not an upgrade, it would certainly be the thing to do. For those of use with 10+ systems, it's not worth a jump. There wasn't even an ESP run for 6.1 since there was so little function that didn't go into 5.4. Some customers did get the new function SPEs early though and tested them extensively.

But will 6.1 run on a z9 or less? No, I've tried it. So for a seamless migration to new hardware, maybe it is not so bad to change one thing at a time and keep 5.4. True, there is less risk going from 6.1 to 6.2, than 5.4 to 6.2, but tomorrow never comes, what happens today determines what happens tomorrow. The way IBM has configured things for 6.1: • shorter expiration date than 5.4, • not much new functionality, • no hardware downward compatibility below z10, 6.1 is, for all intents and purposes, a dead release.

Re: Migrating Maintenance to Level 1 Minimum
I find it easiest just to do the service and put2prod on the production systems. Others have ways of moving all the parts around... but it could be a big inconvenience if you had to put an emergency PTF on quickly. We run service ahead of time and right before the IPL, run the put2prod. We compare the logs left on maint's 191 by the service command to make sure the same things happen there as they did on the 2nd level test.
