Re: taking down the machine - z9 series
From what I understand, myriad regulatory agencies around the world require the single accessible big red power switch design, and not only for servers but also for a wide variety of non-computing equipment, small and large. IBM may or may not have a different design philosophy about its red switch(es), but it doesn't matter. IBM does offer solutions with two power switches. That'd be two frames, ideally coupled and physically separated. - - - - - Timothy Sipples Resident Architect (Based in Singapore) STG Value Creation and Complex Deals Team IBM Growth Markets E-Mail: timothy.sipp...@us.ibm.com -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
Re: taking down the machine - z9 series
I'm afraid I was responsible for a shield, but on a bank of 3490 drives. For some reason, the (unshielded) power switch was placed at EXACTLY the same level as a button on the back pocket of suit pants. Anyone leaning against the drives... The first time an entire string of tape drives powered down, no one could figure it out. I was busted the second time it happened. Soon thereafter shields were velcroed over the power switch. For a while, I was suspected for any unexplained outage, whether it was my shift or not. To the designer of the 3490 cabinet, thanks a lot.

Re: taking down the machine - z9 series
I was working, in Montreal, in the early 1980's. We had a true rookie, out on the floor sitting at an AMDAHL console on the Control Element of one of our 470's. The Payroll clerk had just come in with the bi-weekly card decks for our run. She handed them to the reader operator, and he fed them in, as the cheque run started. Suddenly, she noticed that it was the inputs for the run, two weeks ago. She suddenly screamed that we had to stop the system, it was an emergency. The rookie obliged and hit the big red button to the right of the screen. Bamf! It took four Amdahl reps over 12 hours to replace everything that overheated, because with an EPO, even the fans stop. The rookie got to keep his job though. He was, as I stated, a true rookie, with less than an hour's worth of experience. Of course, we kidded him mercilessly. Especially, the rookies, of which I was one of them. At the time, I was less than 6 months on the job. I never did find out what happened to the payroll clerk, though. - Too busy driving to stop for gas! -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

No just the old 470s ... You cut the fans, you cut the air - then the heat moves from the heat sinks back into the chip(s). Bad, all bad.

Re: taking down the machine - z9 series
I was in a shop in the early 1980s where we had a very bad experience of the power being cut by the use of the emergency switch. There was a building maintenance man in the machine room. When he went to leave instead of pressing the button to activate the door to the mantrap, he pressed the emergency power down switch. They were very close together. It took us the better part of a day to get everything back up. The processor was no problem, but a few disk drives were troublesome. That incident resulted in them moving the emergency power down switch away from the door switch, and a cover was put over the emergency power down switch. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Matan Cohen Sent: Thursday, June 17, 2010 7:45 AM To: IBM-MAIN@bama.ua.edu Subject: Re: taking down the machine - z9 series R.S wrote We shutdown SE SE stand for?

Re: taking down the machine - z9 series
If you have any Os/2 based appliances, then you'd want to gracefully shut them down. Otherwise, they will run CHKDSK upon power up, and that takes forever. Examples of OS/2 based appliances include the older HMC's, 2074's, etc. Not sure if you can do that for the OS/2 based SE's, but, if you can, not a bad idea IMHO. (I believe the SE's and HMC are all Linux based on the z/9's. Linux recovery is fast enough to be left alone.) There is a full power off function somewhere on the HMC or SE. I'd want to find and use that. You'd want to power off DS8100/Shark DASD units. Otherwise, these units will gracefully shut down using their internal batteries but will not come back on line until the batteries are completely recharged. That can take a very long time. Graceful shutdown and power off of other units (tape, VTS, etc) is likely a very good idea. Keep in mind that some units have 'secret' circuit breakers that trip upon full power loss. These 'secret' circuit breakers are supposed to be reset by the CE after power is restored and stable. Have your CE show you where these breakers are, or, better yet, have the CE on site for power up. HTH and good luck. -Original Message- From: IBM Mainframe Discussion List [mailto:ibm-m...@bama.ua.edu] On Behalf Of Matan Cohen Sent: Thursday, June 17, 2010 7:06 AM To: IBM-MAIN@bama.ua.edu Subject: taking down the machine - z9 series Hi, When the situation force you to taking down the machine (due to Electricity power cut) , after taking down the lpars. do you perform anything else beside deactivation of the CPC ? i met a diffrent opinion in this matter . -- best regards, matan cohen MF System Administrator. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.

Re: taking down the machine - z9 series
I have powered down and powered up whole data centers numerous times usually for electrical, power plant work, sometimes because the air conditioning failed, once for a push/pull to retreat from an early CMOS machine, which had more CP's than MIP's ;-), back to a Bi Polar machine, and never had a problem. Coming up just be sure you sequence everything properly, peripherals first, disk, terminal controllers, network boxes, front ends first, then the mainframes. Let each of the devices go through their self-checking sequencing gradually, a few at a time. Make sure everything is up before you bring up the mainframe. The take down is in the opposite order, mainframe first then the peripherals.

You have to know how to power down and power up (more important) your equipment. Yes, it could happen that some equipment would fail during the excercise, but it could fail everytime - you should be prepared for such case as well. Regarding 3174's - yes those machines can work for years, but IML means reading diskettes (assumed no HDD version) and this is the most error prone process. I remember the night when I had to fix 3174 with soldering gun.

(I believe the SE's and HMC are all Linux based on the z/9's. Linux recovery is fast enough to be left alone.) This is a bit of a digression I agree with the advice to shut down gracefully if possible. But there were always ways to reduce CHKDSK running time at bootup. CHKDSK could run for a long time, yes, but the amount of time is proportional to the size of Drive C, the boot volume (in particular). When hard disks were small this wasn't an issue. When hard disks got much larger, then partitioning made sense to help mitigate the problem. (And you can always just create one small partition on a large hard drive, leaving the rest unallocated.) Also, there's a CONFIG.SYS file setting to control which (other) partitions get CHKDSKed at bootup if left dirty. With that CONFIG.SYS setting it's possible to defer CHKDSK of other partitions until after bootup, after the most essential data is checked. The problem was definitely solved with JFS, a journaling file system which IBM added to OS/2 starting with Warp Server for e-business then soon after in the OS/2 Warp client. CHKDSK races through JFS very quickly. Initially OS/2 would not boot from a JFS volume, so there'd always be a small FAT or (preferably) HPFS partition to boot OS/2 (with a fast CHKDSK time). Then you could have the rest of the disk storage formatted as JFS. Nowadays eComStation has eliminated that FAT/HPFS boot partition requirement -- it's now possible to boot eComStation from JFS. By the way, a full OS/2 shutdown is the most graceful, but Ctrl-Alt-Del (followed by cutting the power after the PC BIOS screen appears) was better than just hitting the power switch. Ctrl-Alt-Del didn't give applications the opportunity to perform their own shutdown housekeeping, but it did flush OS/2's disk buffers, close all files, and mark the partitions as clean. - - - - - Timothy Sipples Resident Architect (Based in Singapore) STG Value Creation and Complex Deals Team IBM Growth Markets E-Mail: timothy.sipp...@us.ibm.com -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
