DFSMS/RMS question
We have been using DFSMS/RMS on VM for a long time. At the weekend we had an issue which, I suspect, has happened before but not been identified. We have 16 drives per VTS shared between 6 VM systems (VMTAPE STAM) handles the sharing of the drives. Yesterday, on only one of these drives, I was getting a message that there were no scratch volumes available. An identical mount request (for the same scratch pool) in an adjacent drive in the same VTS was satisfied without problems. I think I know what happened - but I am not sure if this is a bug (or how to handle it). What I think happened is this:- When RMSMASTR was started on this system, it went through it's initialisation process but this particular drive was in use at the time. As a result, RMS is confused. If I am right then a restart of RMSMASTR would solve the problem for this drive but create other potential problems with the other drives in use. Because we have drives in use for long periods of time (by TPF test guest systems) it would almost take a system outage to have no VTS drives in use. Does anyone have any experience or knowledge of this situation? If so then :- a) Does my theory sound correct? b) Is this a reportable bug (should I open a PMR)? c) Is there a way to get round this problem (for example: can I get RMSMASTR to reinitialise a specific drive)?

Re: DFSMS/RMS question
Colin, What is the RC and REASON returned by RMS when the mount request is issued to the bad drive? I assume you've tried the mount outside of VM:Tape using the native DFSMSRM command and that's why you are suspicious of DFSMS in this case?

Re: DFSMS/RMS question
Hi JR, Yes, I have tried a native mount with DFSMSRM and got the same problem. It gives me a RC=8(3140) which suggests a drive problem but I also get a message saying NO SCRATCH80 - although, now I think about it, this was in the VMTAPE console. If I do a DRSMSRM Q LIB DEV EE6 (LIBNAM VTSTPFC2 then I get a message back saying drive not available. While VMTAPE may be misunderstanding the reason for the problem - it is clear that the problem lies in DFSMSRM and not VMTAPE. Incidentally, I can successfully query that drive from another system - giving further credence to my idea that this is caused by this drive being in use when RMSMASTR was initialised on the system where I am see the problem (I think we had a problem with RACF the weekend before last where some service machines needed to be restarted).

Hi, Well I think IBM should share some of the blame as the lack of AFFORDABLE VM training is mindboggling. Why is it that the cheapest z/VM class from IBM is at least a few thousan d? Marist runs their system z program on a mainframe that also runs z/VM. How is it that we don't see any classes from them?
Re: DFSMS/RMS question
A 3140 reason code does mean 'device is not available'. Typically though this is not an RMS problem. The quickest way to find out would be query the drive, and if 'FREE', then try attaching the drive outside of RMS to see if that is successful. Generally there is a reason why RMS could not attach the drive. If the drive was not available during RMS initialization, RMS will later try to initialize and use the device. You should not have to restart RMS. This all assumes you are current with RMS service. Latest RMS service does not require the drive to be free to query it (with corresponding CP service).

Tom, Come to a meeting of the Metropolitan VM Users Association and you will see some VM newbies and VM returnee's. We are getting new member companies and member companies that left VM and came back. Hallelujah. I too started as a DOS/VS Operator then System Programmer all the way up to VSE/SP 2.1, my first VM logon screen also said VM/370. Then in 1990 I was sent to 2 weeks of VM classes at IBM in Crystal City, Virginia. CP and CMS internals classes. Now I was a VM systems programmer and I have ridden the HIGHs of the 90's with thousands of PROFS users and hundreds of VSE guests all running under my VM systems, to the lows of the late 90's and early 2000's and now once again the revitialization of z/VM for hundreds of LINUX guests.

I can remember as I peeled back the layers of VM being amazed each time I found something new, and then figuring out how to use this new treasure.

They acknowledge that there is a problem (add TPF to the list of OSes) and say that they are going to do something about it. Guess what, they never do. They see an increase in personnel costs that makes them put it on the back burner. Eventually, they get hit by the retirement or other loss of a key player and either muddle through with existing personnel, hire outside contractors, or outsource. As far as the demand for VM sysprogs is concerned, the increase in the number of VM licenses has not been met by a corresponding increase in demand for VM sysprogs. I attribute that to the fact that VM has become nearly shrink-wrapped over the years. It takes far less sysprog time to support a system now than it did 30, or 20, or even 10 years ago. The smaller companies look on it almost the same as they do the OSes for x86 based systems - it is part of an appliance. They count the number of x86 systems they have and justify staff based on the numbers. The have only 1 zSystem, so hiring staff to support its OS is not justifiable. What, VM crashed!! Call the Maytag repairman. Indeed. As a vendor, I've seen an astounding decrease in VM skills on the part of customers. Many/most of the new VM customers have *no* VM expertise to speak of, yet are trying to run systems with multiple Linux guests. Some of them have MVS expertise, which is sort of a good thing -- sort of because while it means things like IOCP and PR/SM are familiar, The MVS Way of doing things represents its own challenges (Nobody needs XSTORE any more, things like that). I find that I deal with a lot of very smart but *very* VM-ignorant people, with Linux, AIX, and/or Windows as their background. That means that I spend more of my time onsite, doing things that might arguably be not my job, but which are necessary for the customer to succeed. I think we're in a saddle of the curve. Companies haven't yet had enough experience on the platform to make the staffing justification that they would if it was only one TPF system (running the company's $xxx,xxx,xxx transactions!) or if it was 50 standalone Linux boxes, which of course requires at least one staffer. This is sort of like the early days of Windows servers -- Hey, Fred has a PC at home, he can do it. Only of course having a PC and running a server farm aren't equivalent, which most(?) companies have learned by now. Meanwhile, they hear Linux and free and one mainframe and think Hey, Bob can handle that, he's not that busy, all he does is apply Windows patches and order new hardware, and we won't have to order as much hardware now. Over time, they'll realize that Bob can't keep up with the load and become more realistic, and will be looking for VM skills. Whether that translates into realistic salary expectations remains to be seen: some sites will have drunk so much of the It's Free! Kool-Aid that they will have a rude shock when they do make that realization and start trying to hire experienced VM people. Meanwhile, it's great

Added central/expanded storage...
Folks, Back in Oct or so we installed new z9's with added storage and IFL's. BUT, since we were under the gun we chose to just get us up as were and add storage and or IFL later. So our VM system had 4g of central and 1.5 of expanded. Well, a couple of months later I went to the HMC and added 4g more to central and another 1.5 to expanded for a total of 8g central and 3g expanded. Bounced the VM lpar and it did indeed show via q stor a value of 8g and q xstore 3072m. We've had cause to bounce ALL our lpars several times since, even adding stor to z/OS. We've always say 4-5 hours after a boot of VM consumed 99% of our xstore and I could see paging to dasd as well. This was before and after the added storage. This morning we needed to IML the frame and since that was done we've NOT moved at all from central to expanded. My question is one of - was I really not getting the added storage to VM until and IML was done? IF so, then where does the info come from for the q store and q xstore commands? Brian W.

Re: In search of mainframe engineers
This is very true... And also very wrong. Have you looked at the number of manuals that come in the z/VM set at this point? They now come on a DVD. How would someone, just starting into z/VM, decide where to start reading? Or, better yet, once you read the obvious introductions, where do you go from there? There isn't really a good map provided, and there's so much there that depends on other information in other manuals, that it's difficult to have good comprehension. Sometimes, a good class can help get you started, or can bring it all together and make it gel. -- Robert P. Nix Mayo Foundation.~.

Re: Added central/expanded storage...
Mary Anne, I just issued a shutdown of VM, increased the storage at the HMC, and then activated the lpar. So I actually did NOT do a deactivate at the HMC. Yes we do use v-disks for swap for our linux machines. And that is fine as I'd rather go to exp than dasd. What I am cornfused about is the fact that q store and q xstore as well as I remember looking at perfsvm machine and seeing the added storage, but it sure seems like we actually needed an IML or maybe we needed to deactivate that lpar to actually pick it up.

Re: Added central/expanded storage...
Metrics mean different things to different people. The same thing happens in linux, all storage is consumed, add more, and it's consumed also. You just don't know by what, or if it matters. In both your case and the linux case, you are not looking at useful metrics.

Bounced the VM lpar and it did indeed show via q stor a value of 8g and q xstore 3072m. We've had cause to bounce ALL our lpars several times since, even adding stor to z/OS. We've always say 4-5 hours after a boot of VM consumed 99% of our xstore and I could see paging to dasd as well. This was before and after the added storage. This morning we needed to IML the frame and since that was done we've NOT moved at all from central to expanded. My question is one of - was I really not getting the added storage to VM until and IML was done? IF so, then where does the info come from for the q store and q xstore commands? Brian W.

Re: Forwarding guest console to a syslog server
You have several options. First, Linux syslog: You can set the Linux system's syslog to feed your central syslog server. Most (not all) of what gets thrown on the console will then go there. Second, CMS Pipelines: You can slurp the console traffic via SCIF (aka: SECUSER) into a pipeline running in another virtual machine and feed that through the UDP stage to your central syslog server. Third, PROP and REXX Sockets: You could use PROP (again in another virtual machine) with an action routine to deliver console traffic from the to-be-watched guest via REXX Sockets (UDP) to the central server. All of these are standard equipment (syslog on Linux, Pipelines and PROP on CMS). PROP is typically running on your OPERATOR virtual machine anyway. (Some would say PROP is therefore the easiest to enable for this task. I would say that Pipelines is the easiest on the eyes, though Linux syslog is a one-line change to /etc/syslog.conf.) -- R; () ascii ribbon campaign - against html e-mail /\ www.asciiribbon.org - against proprietary attachments On Mon, 25 Feb 2008, Patrick Spinler wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 A question for all you good folks.

Use the secondary console facility of VM to send the messages of any the linux guests you want to a service machine.

Reason is that prior to today's IML, we were utilizing xstor, now we are not. So, I was looking for confirmation on the commands themselves - ( THANX!! - I figured that was the case but needed a sanity check ) since this was the first IML of this frame in many months.

Re: Forwarding guest console to a syslog server
Actually, the way we have things set up, all of the linux guests forward their syslogs to two central syslog servers. But, not all the messages displayed on the guest console make it in to the syslog. For one thing, any CP messages are lost, and only appear in the z/VM spooled console. We'd like to take these spooled console messages and forward them to the central syslog servers as well, so that everything is in one central location. So what we're looking for would be a syslog client that would run in CMS, accept spooled console files, tag them correctly for syslog, and then send them to port 514 on the two central servers. -- Robert P.

Re: Forwarding guest console to a syslog server
OK, we have a central console log collector we call VMLOGS. All servers do: CP SPOOL CONSOLE START TO VMLOGS. At 1 minute before Midnight we run a CLOSECON EXEC which closes all the consoles. With the CLOSE the console files are sent to VMLOGS. VMLOGS runs WAKEUP (RDR. We read in the console and PACK it to conserve space. You could do a similar thing then run VMFTP to forward the console to your port 514s. -Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of RPN01 Sent: Monday, February 25, 2008 2:12 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Forwarding guest console to a syslog server Actually, the way we have things set up, all of the linux guests forward their syslogs to two central syslog servers.

At one point, I was going to make a ton of easy money cranking out self-paced learning courses. The deeper I got into it the more obvious it became that the only students who actually retained any information from the courses were the very ones who learned quite well from reading manuals in the first place. The material is obviously delivered towards the visual learner and the exercises have to be constrained to the limits of the course environment; there's no go play around and explore with self-paced courses. But mainly, there's no raising your hand and asking a question to clarify your (mis)understanding. No instructor with years of experience crafting analogies, real-world examples, or comparisons to concepts you already understand. (Until the cows come home, if necessary.) And no one to winch you out of the ditch when your playing around leaves you stuck in the weeds. With self-paced courses, you either get it from the text or you don't. Then there is the cruelest aspect of self-paced courseware, as exemplified by [EMAIL PROTECTED]: Would it make sense to have some kind of computer (okay, PC) based education - where the student (their company) buy the class, and the student could not only take the class on his own time - but could refer back to it when he/she shoot themselves in the feet?? On his own time? What own time? How many of us work an eight-hour day and go home to enjoy sixteen hours of our own time? Besides, how much technical material are you able to absorb after a more typical 10-12 hour workday? In short, there is no shortcut. By corollary, there's no cheap-cut either. If you want (to be) a well-trained staff member, it's going to cost some money and time. Preferably time away from the office and interruptions. Time away from phones and crackberries. Time to concentrate fully on the material being learned, and to practice the skills you came to acquire. IBM has a great VM curriculum (most of which I don't teach) including the outstanding Installing, Configuring, and Servicing z/VM for Linux Guests.
