Re: Last update date/time of a minidisk
Rob van der Heij [EMAIL PROTECTED] wrote: When the FST on the CMS disk is written, the timestamp in the directory is updated. Even when you just access a R/W disk, CMS already writes back the FST (that's what triggers the non-shared S/Y stat in the SYSPROF). You can use the mdiskblk stage to get block 3 and then 4 or 5 for the date. I can code an example if you need that. Used to have a pipeline stage that would re-access the disk and pull unseen records from the PROP logging (like tail -f in Linux). A minor correction (Rob knows this, he stated it correctly in a later post, but I want to clarify): The timestamp in the directory is updated by RELEASE, not ACCESS. So if you accidentally ACCESS a disk R/O, you can do one of three things: 1) RELEASE it, updating the timestamp; 2) DETACH (or reDEFINE) it, thus moving it before CMS can update the timestamp and causing an implicit RELEASE (due to the machine check); 3) ACCESSing another disk over it -- for example, if you have 0190 R/W as C, ACCESS 19E C. (2) and (3) above both avoid the timestamp update (OK, to be 100% correct, I haven't verified that (3) does these days, but I'd be surprised if CMS is fancy enough to do otherwise). ...phsiii

Define MDisk Question
First, apologies as I am a VM newbie. (And a linux newbie, for that matter). We would like to be able to add dasd to a linux's logical volume group on the fly. We have been able to do this by making sure all our dasd is onli ne at ipl, then we det the dev from system, att it to our userid, format it, att it back to system and then do a define mdisk from the linux vm userid . We then add it to user direct for the next time the linux user logs off a nd back on. The trouble with this is, the linux guest must have A priveledge and devmaint, which is undesirable. Does anyone know of a way around this? Ideally, what I'd like is the ability to specify a userid on the define mdisk, so that another ID could do it for the linux guest. As I see it, w e either use devmaint or have to logoff/on the guest. Any thoughts or suggestions would be appreciated. Regards, Mary Anne
Re: Define MDisk Question
Your steps are spot-on except for one small part. You do not have to let the linux guest do a DEFINE MDISK nor have class A. Simply add the MDISK entry to the directory and then on the linux guest, do a CP LINK * cuu cuu MR to get access to it. Make sense? In fact, there is a good paper on limiting the privilege class and commands allowed for a linux guest.

Format Allocate question.
Has anyone seen a problem format/allocating a volume where the cpfmtxa format goes from 0-end of a mod-9 successfully with no errors in the console log, but the messages show the volume is being formatted past cyl 3338. When you allocate it will only permit allocation for the 1st 3339 (mod3), I have attempted SPOL 0-end, SPOL 0-3338, SPOL 1-end, SPOL 1-3338, But each time when we attempt to attach to the system it is rejected because of an invalid allocation record. The systems are z/VM 5.1 and z/VM 5.2 both with latest version of ickdsf. The only difference about the definition of the LCU in the IBM ESS is as a 3990-3 TPF rather than the normal 3990-9.

Re: duplicate dasd volume serial numbers
Alan Altmark, I think, talked about this a couple of years ago here. Yes, it does use the first it finds, but it is hard to predict which will be first. If I remember correctly, CP runs parallel or multiple commands out to the I/O subsystem and it depends on the order of the responses as to which volume it will find first. What you should do is define a devno as being offline at ipl in SYSTEM CONFIG.

That's the way it used to work before the XA/ESA I/O subsystem came into existence. I always thought that was still the case but John Franciscovich or one of the IBM Endicott VM gurus set the record straight a year or two ago on this list. Now, the order of what is found first is, at least to CP, random in that the interrupts that are returned aren't necessarily in ascending device number sequence. If you install this way onto duplicate volsers, you're only going to be safe if you set the test addresses offline at ipl in SYSTEM CONFIG and then when you bring up the test system, vary the addresses online and attach them to the guest. That would be the thing to do until you get the volids changed. Jim No. Low device address wins, as long as the low address works. This does not mean that it is OK to have duplicate volume labels. From my explanation, first delivered here approx March 28, 2003, and a few times since. `Once again, here is how CP works at initialization regarding `volume labels. ` `* While RDEV blocks are allocated in subchannel number order, ` they are added to the SYSRIOIX radix tree by device number. ` See HCPIIDFS. `* Many independent tasks are started, each initializing one device. ` These tasks are started in device number order, with no ` regard for subchannel number. ` See HCPIIO near label MOUNEXT. `* It is unpredictable when initialization for any single device ` will be completed compared to any other. `* For DASD that are to be attached to the system, whether CPOWNed ` or user volume, an ordered list is maintained in device number ` order. If multiple RDEVs are found to contain the same volume ` label, the RDEV for the higher device number is not added to ` the list. Effectively, only RDEVs with lower device numbers ` will be attached to the SYSTEM. See HCPIISDV. Message 0954.01 ` is displayed at the operator's console for duplicates at higher ` device numbers. ` `This algorithm was changed a number of times based on customer `feedback. If you remember some sequence that doesn't match `this, you're probably right: at many times in the past it didn't. ` `But remember, if the device with the lower device number is `somehow wrong (doesn't respond, I/O error, whatever), all `your planning based on these initialization rules is probably `broken. Keep unique volume labels for everything to be `attached to SYSTEM. ` `Advice about OFFLINE_AT_IPL is also good to remember.
