RSCS was packaged with z/VM 5.2 as well, even with z/VM Version 4 systems. It might be functionally very similar to RSCS V3, but it should have been an option to license (if needed) the RSCS feature instead of the RSCS program product with z/VM 5.2. Obviously, there's some reason you think you're running RSCS V3 R2, so there might have been a good reason to do so (an old OTC license?), but it'd be an odd configuration. One thing I need to do is assemble some exits and rebuild the RSCS loadlib using the FL540 maclibs. Are you sure? I don't mean to be flip about this, but, a) are you sure you need these exits? b) are you sure the exits assembled under z/VM 5.2 won't run with the z/VM 5.4 level of RSCS? c) how'd they get assembled under z/VM 5.2, anyway? Did someone supply them to you already assembled? If so, do they have 5.4 levels as well? Given your short deadlines and your lack of VM knowledge in house, it might even be worth your employer's money to bring in a consultant to make this happen for you, studying the exits in place and seeing if they're needed or how to assemble them for your z/VM 5.4 system.

This reminds me of personal computer market space twenty-five to thirty years ago: people bought Apple ][s because it had Visicalc. Then Lotus 1-2-3 sold a few IBM PCs. Applications sold hardware.

What hasn't been said specifically is that the 9345 used a weird disk geometry that wasn't quite like the 3380s or 3390s the 9395s and other more recent disk arrays emulate. So, no, you can't. With more recent disk arrays, you probably can match the emulated geometries quite easily, but the 9345s were queer beasts.

Tape drive types?
Has anyone mapped out the values to tape drives types returned by Q cuu ID? Perhaps even listed which types are compatible with what sorts of tapes? (Yes, Herndon, I'm looking in your direction.) I'm trying to come up with a better way of handling tape drives at a DR site, but I figure they have a lot of types of tape drives I don't normally see, and I'd like to know when to charge forward and when to send up red flags when trying to get up and running at a DR site. Thanks, Nick

This way we are using the same hardware and the same CUU, sort of like being at home. I hope that this will give food for thought and will help in the process. This is EXACTLY what I'm trying to avoid. If I call the tape hangers at a DR site, they shouldn't have to care what tape drive addresses I'm used to. It's a lot easier for all involved if I can I can say Hang IM0123 on B00, not, Hang IM0123 on the drive I know as 2F02. Worse, when I was setting up my system, I did a Q V TAPES (when I was a user on their system, not my system) and got a virtual-real address that wasn't B00 -- there was Another Layer of Device Remapping involved. I HATE, HATE, HATE, that DR site providers try so hard to make our hot site system look like our production hardware. Hey, it's VM, and it's a disaster. Give me adequate raw hardware get out of my way, please. OK, I'm weird. This isn't news to anyone, particularly anyone on this list.

That was the intent of my original question, however badly I wrote it. I need to hard code a list of responses I might see to Q cuu ID that might be functionally-close-enough to the 3590-11 I get right now on my production system. Oh, well, I guess I can start with this as a way to separate the 3590s from the 3480s and worry about sub-types later if I start seeing HW errors while doing restores. Thanks, all! Nick

This year's urgent question is, When the mainframe calls in a service problem to IBM, what data gets transmitted to IBM? Is this information published somewhere?

Since, on our previous release of z/vm which was v4r3, we had a 430RES and a 430W01 and they were both CP OWNED, I figured that was the way to go. A volume that is all PERM space doesn't need to be CPOWNed, merely attached to the system if it has minidisks on it for that system. Your old 430W01 may have had SPOL or PAGE space on it, but your 510W01 doesn't. Hope this helps, Nick

Odd sizes for tn3270 sessions
My tn3270 client (Seagull Software's Bluezone tn3270 client) offers me a chance to have a dynamic device that can be any size of terminal besides the usual models: 2, 3, 4, and 5.

MP 3000 console time zone?
Can anyone explain to me the relationship between the time as displayed on our MP/3000's OS/2 Warp sessions and the hardware clock of the real computer hosted by the OS/2 Warp system? This past weekend, as we were coming up after an outage, I decided I was tired of the HMC's time being off by an hour, especially since it didn't put a time zone on date stamps, like in the hardware error message logs. So, I manually fixed the time via the OS/2 clock properties page. When I brought up our z/VM 4.4 system, its clock was off by exactly an hour which, alas, I didn't notice. When I came in last night to fix this gaffe, I went looking all over the OS/2 Warp system for some sort of timezone setting I could tweak so it'd know we were on EDT, not EST, and so the underlying GMT would be correct.(I hate systems whose nominal GMT times are wrong, especially those that are local time, but I digress) Alas, I never could find a time zone setting in OS/2 for EDT vs. EST vs. Alaskan time or anything else, and it's been more than a decade since I used an OS/2 system regularly. I ended up telling z/VM upon IPL that I had to change the hardware clock, so that now at least the mainframe GMT is correct, but I have no idea if I have just made a muddle of things or what. Help? Thanks, Nick
Re: MP 3000 console time zone?
Let me try again, since Ed just sent a very nice, very detailed answer to a question I didn't mean to ask. The HMC on my MP 3000 has some idea of what time it is. Changing it seemed to have unintended consequences on the mainframe clock, as if I had changed the PC's GMT instead of changing its timezone, like I do routinely on the computer that matters. Does the HMC (running OS/2 Warp) have a timezone setting I can change somewhere or not? I couldn't find it, but it's been forever since I last worked with OS/2, let alone had manuals for it. Thanks, Nick
Re: Storage Configuration
Schuh, Richard wrote: We have been on z/VM 5.2 for 2 weeks and have seen the 2G bottleneck disappear as expected. We have seen an ability to run more users as our main benefit. We used to run into the 2G wall with about 100 TPF guests. We have run as many as 132 without complaints since 5.2 was installed. We did uncover a latent demand for cpu time and regularly drive the system over 85% cpu. Now that we have a baseline with our old configuration, we are ready to try to tune our storage allocations and would like some guesstimates of how it should be allocated. The particulars are: Machine:z990 model 305 Storage:56GB currently allocate as 30GB main, 26GB Xstore. Software: z/VM 5.2.0, Service level 0601+ Workload: 90% TPF testing, up to 132 concurrent TPF machines ranging in size from 690MB to 2GB. These machines are driven by CMS machines running scripts, so they are more like batch machines than interactive. TPF acts more like Linux than z/OS. Do the two Titans of performance (or anyone else) have any ideas about how ought to allocate storage as our first try? How is your Xstore being used? Is it dedicated to TPF guests, or is it for some VM function, such as MDC? (My guess is, MDC might be trumped by caching in TPF and your disk subsystems, but the key word here is guess.) How are your paging rates, for that matter? I'm surprised by such a low ratio of Main:Xstore, but since I've never had TPF guests, what do I know? Nick

Re: SPXTape standard labels?
I see I was my usual overly-terse self again. The operators' only role in this is to stick the right tape in the right drive. They don't issue any commands in relation to any of this. One SVM issues a mount request, another SVM validates the tape label (or at least that there's a tape mounted) and gives the drive (and tape) to the first SVM, and the SVM performs the SPXTAPE DUMP and then logs off. The symptom is, for at least two straight nights, the volume-validation SVM has complained that it's not the right tape, and a manual check shows, there's no volume label on the tape. I'd love to blame my operators, but I can't figure out how to, so it looks like one or the other of my SVMs is clobbering the tape's standard label. Nick
