As Bruce indicated, when you identify memory as reserved in the image profile, it's just a reservation. No guarantees that you're going to get it. Memory that is configured on the box and is available to satisfy reservations is detected by the OS as standby. As the various LPARs bring standby memory online, the standby pool is drained. If you see STANDBY fall below your RESERVED amount, then you better hurry. During POR, you can actually see the transition of memory from RESERVED to STANDBY. LPARs are activated as soon as a chunk of central storage has passed POR checks. While the LPAR is activating, the hardware continues validating memory, activating LPARs as it goes. Eventually, it stops activating LPARs, and the remainder of the memory is validated and placed in the STANDBY pool. This process takes time, so beware that VARY STORAGE may fail when issued immediately after POR since the standby pool may not yet be full enough to satisfy your request.

At that time the LPAR epoch [delta from CEC TOD] will be reset to zero, assuming it hasn't been set to a non-zero value in the LPAR image profile. The System z TOD clock is the best clock in the CEC; a precision timepiece that even detects and adjusts for its own drift (up to a point). If you have STP or ETR, then the TOD clock is also accurate. In that respect, Sir Rob's point about using your wristwatch as a time reference is on point. The SE historically syncs its standard PC battery operated clock (BOC) to the CEC TOD every 24 hours. The BOC instantly moves forward or backward. Why bother? Because at POR, the only time reference is the SE BOC -- the CEC TOD will be set to that value. Once accurately set, the time on the CEC is better since it has comparatively little drift. Starting the z196 GA2 upgrade and the z114: o The SE BOC will sync to the CEC TOD once an hour instead of once a day, improving CEC TOD accuracy after POR. o The SE BOC will be steered the match the CEC TOD instead of making large jumps, avoiding a Paradox that could destroy the universe. o OK, so there's no Paradox, but there are NTP-using firmware components in a zBX environment that benefit from the steering You still need STP to have *accurate* time.

Re: password_on_cmds feature statement in CONFIG
Thanks Scott. I use a combination of the guest having its own A disk and a common link to the LNXADMIN user's A disk. The reason I do the separate guest A disk is because I may have differences per guest. Such as I execute the SWAPGEN EXEC to allocate the VDISK from the PROFILE EXEC of the user and a lot of these allocations are guest specific. In the PROFILE EXEC for each guest I have the LINK LNXADMIN 191 391 RR. This is the common A disk. I could move the LINK for this to the Directory entry for each guest, but how do I execute a PROFILE specific to a guest if I am using a common PROFILE for all guests on the LNXADMIN 191(391)?

I believe the PASSWORD_ON_CMDS LINK NO has no exceptions .. once you set it NO - you can't use an inline password - you must be prompted for it (which won't happen if you have RACF controlling LINK). I agree that these LINK statements should be in the directory, though.. maybe part of a directory profile that Linux guests use (e.g. INCLUDE LINUX). I also highly recommend a common PROFILE EXEC on a common 191 disk if that isn't already being used. Make it LNXADMIN 191 191 RR -- and all the guests will execute the PROFILE EXEC on LNXAMDIN 191.

Something wrong with my USERID
Hi I have something set wrong for my userid on this one LPAR and for the life can't see it.

Requires that you explicitly authorize a guest to use one or more VLAN IDs. 3. If you don't provide an authorization, outbound traffic from the guest will be discarded. 4. No untagged frames from VLAN-aware guests will be emitted by the VSWITCH. The new VLAN AWARE and NATIVE NONE are not available on z/VM 5.4. You will have to continue with the VLAN 666 trick.

VLAN and GRANT
Hi This weekend we changed the SWITCH on the Data Comm side to tag a new VLAN (581). Up to this point the switch was only set up for ACCESS switch not TRUNK with a default VLAN of 472. Now the SWITCH PORT is changed to handle TRUNKING. On my z/VM side I set up the VSWITCH to now handle VLAN tagging. Everything looks good on the switch side but when I try testing a z/Linux guest in terms of having it connect to the VSWITCH via VLAN 851 it still does not get to the Subnet pointed to by VLAN 581. I did the GRANT for this guest: SET VSWITCH VSE4DD11 GRANT E49L250D VLAN 851. What am I missing? Now I did not do anything with RACF for this do I need to allow something in RACF? Thanks!

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.

Re: FRAME REORDER FIX
HI Jim, Just to let you know I was able to get the circumvention fix from Level 2. This was able to be installed dynamically and only took a few minutes to install. I implemented it and was able to issue the SET REORDER command for some of my guests. I did get a warning message basically stating that this circumvention was not going to be permanent. But it worked. We were running into some real trouble with some of our large guests. We were seeing these guests stopping for seconds at a time during multiple intervals while reordering was taking place. This was causing major TCP/IP networking issues for one. Once I turned off FRAME REORDERING the delays went away I even saw a drop off in the number of SCAN TWO PAGE STEALS as well as a DROP in Emergency Scan Steals of NSS/DCSS pages. So if anyone is seeing either Console Function Waits (CF) and or FRAME REORDERING taking place you want to turn it off. I will be installing the z/VM 5.4 version of the PTF UM33167 during our next outage so that it becomes permanent.

Depending on the specifics, other possible responses might also include increasing your paging bandwidth or adding expanded storage, but memory does seem the most obvious. It's impossible to say without knowing the details - this is definitely the sort of case where Bill Bitner's favorite saying (It Depends) applies. If you are experiencing current problems, you can always call it in. Being more of a designer / coder than a performance analyst / tuner, myself, I hate to try to give general advice without knowing specifics, and this isn't really the best place to have that detailed discussion. All that said, if increasing your memory within the supported range introduces any new problems, certainly let us know through normal support channels. - Bill Holder, z/VM Development, IBM Endicott On Mon, 11 Oct 2010 19:22:55 -0400, Martin, Terry R.

Other symptoms may be possible as well, depending on workload characteristics; we haven't experimented with, measured, and analyzed all that many different kinds of workloads in such large environments.

.PCAP file form TCPDUMP in REDHAT
Hi We are working on a problem and trying get a .PCAP file produced from TCPDUMP to send to IBM. We got the .PCAP file but it was 3G before being zipped. My question is are there some parameters that we can specify that will make the .PCAP file more manageable so that IBM can work with it via WIRESHARK?

There is a command line component to Wireshark called tshark.
You can extract the data based on filters etc

Re: CP unresponsive on certain guests
Yes, and the original statement was based on the assumption that the over commitment of real memory was high. Obviously if there is little to no over commitment than you will see very little paging from z/VM on behalf of the users. I will also add that even in z/OS say you are running a good size DB2 environment if you do not have ample real storage you will still see paging for sure to your paging subsystem and without expanded storage no longer available in z/OS it will go right to DASD.

In the z/OS world paging has become virtually(no pun intended :-)) non-existent. z/VM does very little paging (if not zero) on behalf of itself. Because z/VM allows considerable overcommit of storage among the various guests, it can wind up doing a _lot_ of paging to manage all that. If you ever started using z/OS as a hypervisor, it would have the same problem, unless you strictly limited the amount of virtual storage each guest had to add up to less than the available real storage. Mark Post
Re: CP unresponsive on certain guests
I would just add that for any significant number of z/Linux guests it is imperative that you have a robust paging subsystem and enough spool space to hold CP dumps as well as other spool files. Having a well configured paging subsystem will greatly reduce the possibility of issues when your system has a high paging rate due to the over commitment of Available Real Memory versus the total memory of all users running in the LPAR combined. The higher this over commitment ratio the more paging is introduced. The good news is as long as you have a sufficient paging subsystem z/VM handles paging nicely even at relatively high rates. So over commitment of real memory in z/VM is good just keep an eye out so that the ratio stays within reason.

The answer to your first question is to use the CP FORCE command (HELP CP FORCE will tell you all about it.) The VM user id issuing the FORCE command needs to have privilege class A as well. Usually this is done from either MAINT or OPERATOR. The answer to your second question is a bit more difficult, I'm afraid. As Marcy has already suggested, what does a Q SRM command show? My first guess would be that your SLES11 guest is falling into Q3 and never given an opportunity to run. To find out *why* the guest is not able to run, you need the services of a good z/VM performance monitor.IBM offers the Performance Monitor (it comes bundles with z/VM, but it's an extra cost offering) and Velocity Software (http://www.velocity-software.com/) has a very good suite of products as well. IMHO it' practically impossible to run a modern production grade z/VM-zLinux system without a good performance monitor to help solve issues like the one your having now.

Hi Neale, That was it, I was concentrating on 9700 so much that I forgot about other two addresses (9701-9702) in the triplet. So sure enough there were still offline.

How to copy a disk using a z/Linux guest
Hi I am trying to find out if there is a utility in z/Linux in my case RHEL 5.2 that will allow me to copy a z/Linux formatted disk to another disk. Also do you know if DDR cares rather there is a VTOC on a volume if it is used to backup the volume without a VTOC?

Re: How to copy a disk using a z/Linux guest
Hi Further explanation. Here is my dilemma in a nut shell: I have a z/Linux volume on a guest that does not have a z/OS VTOC. We typically use DFDSS on z/OS to back the z/Linux disks up and restore them at out DR site. Since this particular guest does not have z VTOC DFDSS cannot open it. So given this we decided to use DDR for this disk but the guests have the disk allocated so we are not able to attach the disk to the user that would be doing the DDR. So the only way I know to get this backed up is shutdown the guest and then attach the disk to the user doing the DDR. So I am assuming that if I do this that DDR will back up everything needed on this pack to do a good restore at the DR site. Are assumption good here and is there other ways to do this say without bringing the guest down?

Re: How to copy a disk using a z/Linux guest
Thanks to all for the information this will help prepare backup and recovery processes moving forward: First, we do not count on Full pack backups for our restores normally we use FDRUPSTREAM to backup the guests file systems on a daily and weekly basis, however the guests are still running when this is done other than the Data Base backups where the guest is shutdown and a full backup is taken of the Oracle data base using FDRUPSTREAM. Since we just started adding the z/VM and z/Linux environment as part of the DR testing we are still feeling things out. For instance this will be the first time that we will be taking FDRUPSTREAM with us. The last DR test which was the first one we restored one guest all ECKD DASD from FULL DFDSS backups running on z/OS. Second, for this exercise there is no LVM involved these are just ECKD devices. So synchronization will be less of an issue for these guests and for this test.

Dr Boyes could speak could speak on this point better And you always want to shutdown the guest to get a good backup Long term, setting up Bacula would probably be a Good Thing, but probably doesn't help much in this scenario, other than to give you a convenient way to dump and restore the contents of the filesystem onto a new disk that doesn't have the missing VTOC problem. The question in my mind is whether the last cylinder of the pack is actually in use and/or whether the filesystem could be resized online to be 180K smaller (so as to free up the last cylinder). DDR is smart enough to be able to relocate the disk image (eg, restore it to cyl+1 on another disk), but that won't fix up any internal references to the filesystem size or LVM magic that might be there, and you will get Weird Failures that you really don't want to try to track down. If it can't be resized or is part of a LVM, then you're SOL on that solution. Ultimately, if you want to keep using DFDSS (and I'll point out that you have been EXTREMELY lucky if you haven't had failures of your backups) the solution is to allocate a new pack with a proper VTOC in cyl 0, and follow the instructions on linuxvm.org to migrate the filesystem from the current disk to the new disk. Short of that, you'll have to use DDR for those two packs (if you use CMSDDR, you can store those two disks as CMS files on one of the other packs, and then restore them back to real DASD from there). That's probably the only way you'll be able to do this quickly enough for your DR test. Larry's suggestion of Bacula is a better long term solution, but that takes a bit of planning you probably don't have time to do now. -- db

OK, if you're running the FDR/Upstream agent inside the guest, you probably are going to be OK. That satisfies the requirement of backing up the systems from within the guest, so the backup will likely be reasonably consistent. Second, for this exercise there is no LVM involved these are just ECKD devices. So synchronization will be less of an issue for these guests and for this test. *whew* LVM is a PITA for this sort of stuff. Necessary, but a PITA.

DR Backup using DFDSS
Hi I have a dilemma. All of my z/Linux DASD volumes are formatted for a VTOC on cylinder zero so that I can leverage the z/OS DFDSS backups of these volumes. No problem, however I am getting this one guest ready for DR and as such running DFDSS on z/OS to accomplish this. This particular guest has 2 volumes that do not have z/OS VTOC (Dedicating them in the Directory entry) therefore DFDSS receives the ADR307E: error message basically because there is no z/OS VTOC. I know I could use DDR on z/VM to get around this but the problem is that these volumes are in use and I need to attach them to whatever machine I am going to do the DDR from and cannot go to another LPAR because these particular volumes were not gen'ed to be accessible from any other LPAR but the production (separation requirement). So is there any way I can get these backed up given the above?

Re: DR Backup using DFDSS
Hi Yes, I knew that the backup would be a 'fuzzy' one but I have not had an issue with restoring since I am doing a physical cylinder by cylinder backup. We do use FDRUPSTREAM to handle the incremental and full backups of all the DASD for each guest, but the DFDSS is a little different.

Dedicating volumes don't have any affect on whether there is an OS VTOC on it or not, it's how Linux was told to format them. If, during dasdfmt, CDL was specified (or taken as a default) there should indeed be an OS VTOC that would allow it to be varied online to z/OS. (It was kind of the whole point of creating the CDL format.) If they are CDL formatted and there is no VTOC, then you have a huge bug that needs to be dealt with. If they are LDL formatted and not CDL, then you need to change your procedure to format them. Mark Post

Re: ICKDSF format of new DASD
Dennis, I say INIT but I am really referring to the 'FORMAT' parameter of CPFMTXA. Below is an example of an EXEC to format cylinder zero with the z/VM Label. The INPUT file 'INPLVD1' has the RDEV and LABEL. Of course you can do the same by executing CPFMTXA interactively and specifying to parameters as prompted: / OR USE */ trace o makebuf; 'EXECIO * DISKR INPLVD1 FILE A (STEM' RECORD. 'FINIS' do i = 1 to record.0 rdev = word(record.i, 1) label = word(record.i,2) queue 'format' queue rdev queue '0-0' /* queue '0-END' */ queue label queue 'YES' queue 'PERM 0-0' /* queue 'PERM 0-END' */ /* queue 'PAGE 1-END' */ queue 'END' cpfmtxa; End; dropbuf; INPLVD1 file: 6C6A B34V80 6C6B B34V81 6C6C B34V82 Thank You, Terry Martin Lockheed Martin - Citic z/OS and z/VM Performance Tuning and Operating Systems Support Office - 443 348-2102 Cell - 443 632-4191 -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Dean, David (I/S) Sent: Tuesday, July 20, 2010 3:54 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: ICKDSF format of new DASD How do you init, with CPFMTXA?

This process depending on the amount of DASD being presented to the guest can take two or more hours to complete with the majority of the time being spent on the DASD initialization phase of the Kick Start. As Hans points out, it has considerable systems management advantages to leave the real volser to CP. Some of the claimed performance benefits of dedicated DASD seems to build on hearsay, ancient VM releases, wishful thinking and fading memory :-) But you can save yourself some time by not initializing the volume on z/VM first. For volumes that only contain mini disks, it's enough to format cylinder 0 only and put a label on (the RANGE option in ICKDSF). The virtual machine will need to format the mini disk anyway. The recommendation to do it twice (just in case) stems from a Linux bug that was fixed 8 years ago. Just remember that for page and spool packs, you *do* have to format the full volume. In the early days, Linux' dasdfmt also had the option to format only part of the minidisk. This option was removed because some people misused it and then reported a problem when the disk was not formatted. Since you can't prevent Linux from formatting, the alternative is to skip the formatting on z/VM (as explained above). If your DASD subsystem has magic duplication features (snapshot, flashcopy, etc) you can skip both steps. To do that, you once prepare a disk with dasdmft (and maybe even mkefs2) and use that as the source to flash over a fresh volume when you need a Linux disk. If supported, you can just flash the large mini disk. Otherwise, you flash the entire volume and use ICKDSF to relabel the real volume (that does not touch the mini disk at cylinder 1). That's where it helps to let each Linux have the same virtual volser for the disk. Rob
Define FULL PACK MDISK or DEDICATE z/Linux DASD
Hi I am sure this has come up before but I could not find it in the archives (getting oldJ). Anyway, during our z/Linux guest build process, which we are doing at a very fast pace, we end up initializing the z/Linux DASD under z/VM. Now, when we execute the z/Linux Kick Start that process comes right back and initializes the same DASD. This process depending on the amount of DASD being presented to the guest can take two or more hours to complete with the majority of the time being spent on the DASD initialization phase of the Kick Start. The question is would it help to Dedicate the DASD to the guest instead of specifying a FULL PACK MINI-DISK for the DASD? I am assuming that by Dedicating the DASD that I could skip the z/VM initialization phase and just let the z/L:inux OS initialize them at Kick Start time. This would save a bunch of time during the build process. I wanted to be sure what the pros and cons were if I decided to go this route. Thanks in advance to the help!

RH fix is here http://rhn.redhat.com/errata/RHSA-2010-0398.html bugzilla 580839 ). The IBM kernel crew had fixed the problem in later kernels preemptively. We haven't put the microcode fix on yet. Our first opportunity in dev is later this month. While it is HIPER, I would bet its pretty rare. We have a ton of other workload across a half dozen z10s and it only has affected this one particular application. One thing interesting to note that was new to me being a VM person from way back... in Linux if a problem like this occurs that the kernel detects, the process that tripped over it will be killed and linux will continue on. So in our case that meant restarting the java application and the server itself didn't' need to be rebooted. If the VM CP nucleus had tripped, a hard abend dump would have been taken and VM would have restarted itself. While this is more drastic and probably much more impactful, it lets IBM get what they need right away instead of spending a lot of time trying to diagnose things without the dump.You can make Linux act like this if you wish (and I'm pondering making it our default in the standard builds here..). You can turn on kernel.panic_on_oops . Linux will go into disabled wait and then you can dump it. There's even ways to make it dump automatically or you can #CP IPL dumpvoladdress and capture it that way. There's some SHARE presentations that go into the details so I won't. You do want to set up a dump volume with the dump program on it rather than trying to use the CP VMDUMP command which will result in you sitting and twiddling your thumbs for 2 hours to dump 6G... One could monitor their /var/log/messages to see if they have any processes being terminated with exceptions and check if this problem is affecting their applications.

That's something we discovered. Only z10 too, not any other z. See my posts here ealier this year (on linux-390) with low address exception in them. In our case, a 4 vcpu 6G guest running java is affected. Seems to be somewhat load related and definitely some apps are more susceptible than others. Coincidentally, there is also a kernel bug with the exact same symptom. Both RedHat and SuSE have fixes for that. Here's the details in case anyone doesn't have access to resource link --- RL: Hiper Document Number: 060310 Machine Type: 2097, 2098 Models Affected: All Models RETAIN TIP: H174493 ABSTRACT: HIPER MCLs have been released for machines at Driver 76 and Driver 79 DESCRIPTION: HIPER MCLs have been released to address an issue reported in the field. This issue has only been seen in the Linux on System z operating system running as guest under zVM and has resulted in a Linux abend. This issue occurred when the physical CPU transitioned from handling one guest configuration to another. A very small window exists where the update of the hardware controls related to multiprocessor address translation were not handled properly. There are no methods to avoid exposure to this issue other than installing the specified HIPER MCL's. This problem has only been reported when running Linux on System z as a guest under zVM. However, IBM believes it could also occur when running other operating systems. Although an undetected data corruption has never been reported as a result of this issue, there is a very small chance that this could occur. The following HIPER MCLs have been released to eliminate the exposure: Driver 73 -- Driver-73 entered End of MCL Support August 2009 and a fix for this issue will not be released for this Driver. Product Engineering strongly recommends upgrading to Driver-79 to obtain this fix. Driver 76 -- MCL's N10967.101 and N10967.102 of the I390ML stream released to RETAIN on June 1st, 2010 in MCL bundle #47. Driver 79 -- MCL's N24406.032 and N24406.033 of the I390ML stream released to RETAIN on June 1st, 2010 in MCL bundle #31. RECOMMENDED ACTION: Product Engineering recommends the installation of HIPER MCLs . These MCLs can be installed concurrent with system operation. Note- Driver-76 is currently in Limited MCL Support mode and will enter End of MCL Support on June 30, 2010. Product Engineering strongly recommends upgrading to Driver-79 during you next microcode maintenance window. Driver-79 was released in November 2009 and is running on 40% of the z10 machines in the field. Driver-79 is also the last planned driver for z10. EDM Considerations: The installation of these HIPER MCL's at Driver-76 will exceed the current EDM min/max definition for concurrently upgrading to Driver-79. A new EDM sync point is being developed and is targeted to be released mid to late June, 2010. The following options are available: 1) Upgrade to Driver-79 and install the latest HIPER MCL's 2) Install the latest Driver-76 HIPER MCL's and wait for the next EDM sync point to be released. Note: Since these Driver-76 HIPER MCL's exceed the current EDM min/max level you need to take additional actions to ensure the MCL install and activate process overrides the current min/max level. To do this you need to insure that you select the 'check box' Include internal code changes which will inhibit Concurrent Upgrade Engineering Changes (EC) task from being used to apply the next Licensed Internal Code (EC) level. before installing the Driver-76 HIPER MCL's.

OSA Question
Hi Well we converted to a z10 this weekend. We had a few issues but got through them. There was one fall out with the OSA. Before the conversion we had an LPAR that has access to a set of OSA UCBs and these UCBs were defined to a VSWITCH. After the conversion these OSA UCBs were no longer accessible from the LPAR. We found that there was an issue in the GEN but not until after the fact. So we found another set of OSA UCBs that were accessible to the LPAR and they work. Now since I had to destroy the VSWITCH and re-define with the new real OSA UCB do I need to recycle the Linux guests that are using that VSWITCH or is there another way without bringing the Linux guest down?

Then use the CP COUPLE command for the linux guest to connect it to the vswitch. FWIW, it's too late now, but you could have just added the new address to the vswitch instead of destroying and recreating the vswitch. I've done that when migrating from one OSA port to another.
