I know that it can provide better security for the connections. Does it also help with performance? Another reason to use NPIV now on your z9 is looking ahead to a future move to a z10: On z9 if you don't use EDEV or NPIV to control access to LUNs you'd use IBM's LUN Access Control utility, but when you get to a z10 you'll find z10 doesn't support LUN Access Control utility so you'd do without LUN Access Control or have to migrate the guests to NPIV or EDEV.

Re: Using FDR Instant Backup to make FlashCopies
z/VM does take first device matching a VOLSER . Enter CP QUERY 4506-4507 to see what volid CP saw on them. And check you guest's DEDICATE's to see if they're still DEDICATE by volid: DEDICATE 1500 VOLID x. If the 4506-4507 volid's match the DEDICATE's then CP dedicated them to the guest instead of the like-named volids at higher addresses as you suspect. If you must DEDICATE full packs then it'd be more reliable to DEDICATE by address instead of volid, using DEDICATE 1500 4701 this succeeds if the dasd is 'FREE' and is independent of its volid; if you use the 'volid' option then the DEDICATE will fail if the volid isn't what the DEDICATE specifies, as in DEDICATE 1500 4701 VOLID LEMAI1 HCPLGN090I Device 1500 not defined; device LEMAI1 not available. Put the 4701-4708 dasd OFFLINE_AT_IPL in SYSTEM CONFIG and vary them online in AUTOLOG1's PROFILE EXEC before the guest is autologged. From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Karl Kingston Sent: Wednesday, September 02, 2009 2:13 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Using FDR Instant Backup to make FlashCopies We're running a Domino mail server under z/Linux under z/VM. Volumes are full-pack volumes and are dedicated to the VM guest when we autolog the guest. Dedicates are in the form of DEDICATE 1500 VOLID x. This has worked well for us. For backing this system up, we use FDR from the z/OS side to backup. Of course, the linux system is down when we do this so we can get a clean copy. Since we're using 8 3390-27's to hold our mail files, our backup window is about 2 hours. In an effort to reduce the size of the window, we used FDR to Flashcopy these volumes to other DASD.And then backup these DASD. My understanding is when using FDR to flashcopy, it will change the VOLSER for the target devices (can't vary them online to z/OS). Our VOLSERS are LEMAI1 - LEMAI8. Reside on units 4701-4708. Our flashcopy targets are on 4506-450D. This scenario worked for several weeks until yesterday. When we autologged the guest machines, somehow they grabbed 4506 and 4507. (I'm assuming somehow the volsers got changed?) Has anybody had any experience with doing something like this? Any idea why z/VM assigned 4506-4507? Correct me if I'm wrong, but z/VM will take the first device it finds matching a VOLSER? What can we do to remedy this? Is this even a good idea?

Re: Stand-alone IPL of a Virtual tape
Ismael, To mount a VTS tape in your bare LPAR your VTS administrator can use the IBM Total Storage Tape Library Specialist browser-based application to do a Perform Standalone Operations (PSO) mount of a VTS tape in a VTS drive address available to your LPAR. A non-browser-based PSO method is documented in IBM ATL 3494 Operator Guide GA32-0449-07. (was true back in 2005; might use different tools now to do the standalone mount function). I've used PSO to mount stand-alone DSF and DDR VTS tapes in a bare LPAR. The PSO screen doesn't use 4-digit VTS drive addresses, you use parts of the drive address to indicate VTS Controller number and device number. Again, this was back in 2005 and might be easier by now. Check with your Storage/VTS administrator.

Re: Multiple zVM Lpars - Resource consumption
I have a site like you describe: 2 z/VM LPARs sharing all the IFLs, also sharing channels to dasd, tape, etc. One LPAR for test/development Linux guests, the second for production linux guests. The PRSM overhead seems negligible, 0.5-0.6%. The memory for linux guests dwarfs the memory needed to run z/VM OS, 64M or whatever the manual says now for z/VM. We give the production LPAR a higher partition weight than test/dev LPAR and more central and expanded storage than the test/dev LPAR. We find the extra work/complexity of maintaining 2 z/VM LPARs is outweighed by the benefits of isolating the workloads and being able to schedule outages on each LPAR independently of each other. -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Mark Jacobs Sent: Wednesday, July 22, 2009 1:18 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Multiple zVM Lpars - Resource consumption Can anyone give me an estimate on additional resource consumption if we take one z/VM lpar with 'x' IFL's, 'y' GB of memory and 'z' Linux guests and we create an additional z/VM lpar sharing some/all of the IFL's, taking some amount of the memory and some of the zLinux guests.

Re: Clean Linux Guest Shutdown
Bob,
I think it's as the others said, Linux is shutting down the way you told it to
do but not the way you intend it to do:
Here's how we shutdown a disconnected sles 10 oracle server gracefully here,
hope the example helps you:
/etc/inittab has a record to run 'shutdown -h now' in response to the SIGNAL
SHUTDOWN or FORCE WITHIN
ca::ctrlaltdel:/sbin/shutdown -h -t 4 now
our zipl.conf doesn't have any vmpoff/halt-whatevers in it.
CP Q SIGNALS shows the oracle guest enabled for the SHUTDOWN signal
Signalled Timeout
UseridSignalSignal Status By Remaining
DZ2DF138 SHUTDOWN Enabled - -
init script dbora (see listing below) with proper comment headers is in
/etc/init.d/dbora
I ran command 'chkconfig dbora on' so the start/kill symlinks to dbora are
built in /etc/init.d/rc.3/
'chkconfig -l dbora' reports dbora is on in run level 3
dz2df138 is running disconnected; From VM did CP SIGNAL SHUTDOWN dz2df138
On dz2df138 oracle shutdown cleanly and then linux finished shutting down, and
VM then logged off dz2df138.
This is our /etc/init.d/dbora script:

The concept having been successfully proved I'd now like to rip out that interface and replace it with something that stands some chance of being reliable. The question is what?

I'm surprised by another discussion that seems to say that SFS is not reliable or dependable. Is that true in your shop? How heavy of a use it it? Here, I'm the major human user. The other 6 users may or may not use it on any given day. However, I count 34, CMS type servers, that I have running, that make use of SFS as part of their normal functions. That includes PROP which logs to a SFS directory 24X7. And FAQS/PCS serves system related jobs from SFS directories to the VSE machines. I have 6 storage pools. Historically there were of a size that the backup would fit on a single 3480 cart (compressed). Now, that isn't a requirement. All my VSE machines (14 currently) have their A-disk on SFS. That directory is also where all the systems related code is stored (IPL procs, CICS stuff, Top Secret security stuff, DB2 stuff, and all vender related stuff). No application related stuff to speak of. In the 15 years, here, I've never had a problem of not being able to bring up VSE due to a SFS problem. And in the last 5 years, I've never had a problem bringing up Linux images due to SFS availability. I have had problems of the loss off the CMS saved segment due to a bad VM IPL. This was usually due to a duplicate CP-OWNED pack being brought up instead of the original. Ahhh, for the days of being able to go to the IBM 3990 or IBM 3880 and disabling the address of the wrong volume.. I've had SFS problems where the SFS backup cancelled due to tape I/O error and the backup wasn't restarted (which would unlock the storage pool that was locked), which caused users that want to access that pool to be denied. But I was surprised at the people claiming that SFS wasn't reliable, when all you need it for, was to serve the PROFILE EXEC to bring up the Linux image. I guess it is once burnt, twice shy, and I guess I haven't been burnt yet. In my world, I don't do CMS minidisks, if I have a SFS option available. I think SFS is reliable.

Re: How does z/VM obtain time ?
Ann, If you don't use the z/VM IPL prompt to change it's LPAR'as TOD clock then z/VM's LPAR gets its TOD clock set equal to the External Time Reference (ETR) or on z10 Server Time Protocol (STP) time at LPAR-activation time if you're using an ETR or STP, and thereafter the LPAR's TOD drifts a bit. Unlike z/OS, z/VM doesn't include the code that supports keeping in synch with the ETR/STP. See Sysplex Timer and VM http://www.vm.ibm.com/faq/vmgen.html#Header_2 See http://www.redbooks.ibm.com/redbooks/pdfs/sg242070.pdf page 83 section 4.2 VM/ESA Long story short- if your machine's TOD clock is set ok then just let z/VM's LPAR inherit it.

Re: z/OS on z/VM Eligible List
I think your original problem description I had a z/OS go into z/VM's ELIGIBLE list. The z/OS stopped completely and the console was unresponsive. and that decreasing its memory from 1G to 512M fixed it are the major clues. It's possible z/VM memory is overcommitted (normal) but its default SRM values are sending guests into eligible list, especially since you say you're running linux guests. Are you running more linux guests than usual? or increased their memory size? did/are other guests going into eligible list too?

Re: Using WakeUp to cycle a zLinux instance

Re: Need help preparing a presentation explaining how zVM manages storage....zVM 5.2
Brian, I suggest you don't define another 2gb Linux guest else VM might run out of page slots and then crash. Ignoring performance issues, your 2 mod3's of 4.6gb of pages + 8gb C + 0.5gb X = 13.1gb and another 2gb Linux guest (14gb of Linux pages) will force CP to page the excess to your spool dasd which might not have enough free slots, in which case VM crashes.

Re: error bringing up cloned system
I see your point, I was think of the other case where the filesystem is on a mdisk and cloned copy's mdisk is on another pack. I think each z/vm dasd pack has a unique hardware id; your cloned copy's pack has an id different from its parent's id; if /etc/fstab isn't adjusted after cloning to mount the copy's by-id value then the server has trouble booting when it tries to mount using the parent's by-id/ value.

We have been struggling with this question ourselves. We licensed a CA product called Brightstore Archive Bakup (BAB) two years ago. After two years of fighting with it, we just decided to delete it. It never worked reliably. The reason to choose BAB was that it will backup to mainframe tapes (such as our STK Silos). The other Linux products want to use midrange tapes instead. You might want to ask about Linux backups on the LINUX-390 list instead of this list. See http://www2.marist.edu/htbin/wlvindex?linux-390.

Re: DFSMS for VM Exit FSRMDEV
Horst, I can send you assembler and VMSES instructions for a working DFSMS exit FSMRMSHR (RMS Library Partitioning). FSMRMSHR calls a Rexx EXEC to do its actual work. You would have to adjust a few assembler lines and names to convert it into your desired FSMRMDEV exit that calls a Rexx EXEC. The main effort is the 2 exits have different parameters but should be easy for adventurous, novice assembler to adjust the parameter references. The parameter types of FSMRMDEV are a subset of the types used by FSMRMSHR except for FSMRMDEV's 'Real dev address' bit(16) input parameter for which an example is probably in the 'z/Vm Application Dev Guide for Assembler'.

When we do mount requests without specifying a real device RMS will try to use the first available device nevertheless its a 3490 or a 3590. So the recommandation from IBM to solve our problem is to modify the exit FSMRMDEV. The exit should be written as a assembler program that calls a REXX-procedure where the logic resides. I found the following text in the redbook 'Guide to Sharing and Partitioning IBM Tape Library Dataservers' SG24-4409-02 FSMRMDEV The real-device-selection exit, FSMRMDEV, can select a device when a real device address is not specified in the incoming request. Users can provide their own device selection algorithm. The product default processing selects the first available (unattached) library tape device that can be located. The request fails if no devices are available. Note: This exit becomes highly interesting in an environment of mixed drive types where getting the correct media-drive match is critical. A sophisticated exit may be required here, to match a selected device type to a particular scratch pool being requested, or a volume serial number within a customer-defined range that represents a certain media type. Has anyone modified this exit ? I am looking for a sample how to do it ? I am familar with REXX but not really with assembler. I appreciate any sample.

Leland,
If you're looking at code for that swapping algorithm:
what happens when highest priority swap area (swap1) gets to the end,
swap1 has free slots and the next higher priority swap area (swap2) has
free clusters?
Does linux start over at the beginning of swap1 and fill swap1 before
allocating from swap2?

Rob said earlier that after linux starts using a lower priority swap area it doesn't migrate back from swap2 to swap1 when stuff is freed later.

Re: Questions about LUN DASD volumes
FYI, SCSIDISC requires a LUN zero exist and be accessible in each storage controller to be scanned. Assuming non-NPIV, If one's using IBM San Volume Controller then consider having the very first LUN (LUN ) that each of its I/O Groups maps to your host (mainframe) be a minimal size LUN that will exist but not normally be used. That way its always free for SCSIDISC's need. Otherwise if LUN zero's in use by z/VM CP or a linux guest, SCSIDISC can't use it to scan the LUN's storage controller (SVC I/O Group).

Re: Trying to build CMSBAM segment
welcome to the can't build CMSBAM club, been happening for at least 2 years, seems to have stumped IBM support since they recommend even now I continue to use this workaround. Quick, easy workaround is based on knowledge CMSBAM hasn't changed and doesn't really need to be rebuilt, so lie to VMSES as follows: on Vm5.3 MAINT 51D edit VM SRVBLDS, locate line that begins like :BLDLIST.SEGBLIST :OBJECT.CMSBAM.SEGMENT :STAT. and edit it to look like :STAT,BUILT.yy/mm/dd.hh:mm:ss.blurb :BLDLIST.SEGBLIST :OBJECT.CMSBAM.SEGMENT :STAT.BUILT.03/30/06.11:42:47.JOHNR If you used SERVICE command then on MAINT 191 there's a recent SERVICE RESTART? or something file with 1 or more records.

Re: CPU usage data
If you have DISKACNT collecting the CP account cards from a few typical days or weeks you could run ACCOUNT command against them to report cpu usage of the whole system or each userid. CPU usage is on the type 01 cards. Assumes you do a CP ACNT ALL to get the 01 cards for userids that don't logoff frequently. Convenient to do CP ACNT ALL at 23:59:58 every day for a few days; that will generate 01 cards with the correct ending date (that day) covering the previous 24 hour period. Omit the partial day file for the first day you did ACNT ALL, then COPYFILE (APPEND to put all the daily account files into 1 file that you run the ACCOUNT (on MAINT's 193) command against. In the output PRT file report, column REAL-CPU is the # of CPU secs used by each userid, the TOTALS line is total REAL-CPU of the userids and CP.

Is it that you have 16 GB real and nothing else to do with it? Is it that you have a current Oracle box that needs more and more memory? The performance characteristics of mainframes are quite a bit different then the other platforms. Your box, should have Ficon/FCP channels. The promos on our IBM DS6800 dasd subsystem, states that if it is properly configured (ours is not), it can do 300,000 I/Os per second. What do your current platforms have? What I'm getting at is, take Intel for example. Very cheap memory. Very cheap MIPS. Poor context switching. Poor I/O rates (unless you spend mainframe type dollars to beef up the I/O subsystem). So you throw lots of cheap memory on the box to knock down the I/O rates. (cheaper than beefing up the I/O subsystem). On the mainframe, we have the I/O subsystem (basically comes standard...well for the price we pay for the box). In my book, you trade memory for a higher I/O rate and you still get great performance. True, you may still need the memory. But just because the Intel side needed the memory, doesn't mean the mainframe side needs it. True, I would keep memory at 16 GB for a POC. But if I had the time, I would scale the memory back, perhaps a GB at a time, until I see performance start to suffer. In other words, take advantage of the resources available on the new-to-you platform. All the rules of thumb that you have seen for Oracle, really need to be rethought in the shared environment of the mainframe. If you treat the mainframe like a PC, it will be a very expensive project.
