Why a UPS FAIL let down a 3000's shield

Fail
Previously, when a pair of HP 3000s were felled in the aftermath of a windstorm which clipped out the power at Alan Yeo's shop, his Uninterrupted Power Supply in the mix failed as well. After a couple of glasses of merlot, our intrepid developer and founder of ScreenJet continued to reach for answers to his HP 3000 datacenter dilemma. Why did that UPS that was supposed to be protecting his 3000s and Windows servers FAIL once the power died?

Second in a series

Feeling mellower and with nothing I really wanted to watch on the TV, I decided to take a prod at the servers and see what the problems are. I decided I'd need input to diagnose the Windows Server problem, so that could wait until the morning. Power-cycled the 917 to watched the self-test cycle and got the error, did it again. (Well sometimes these things fix themselves, don't they?) Nope, it was dead! 

Google turned up nothing on the error. Nothing on the 3000-L newsgroup archives, either. I'd tell you the 3000 error code, but I've thrown away the piece of paper I had with all the scribbles from that weekend.

Where's a guru
when you want one?

I really wanted to get my 917 back up and running over the weekend, as it had all our Transact test software on it. Dave Dummer (the original author of Transact) was doing some enhancements to TransAction (our any-platform replacement for Transact) and we had planned to get some testing done for early the following week, to help a major customer.  

So it's 11:30 PM UK time, but it's only 3:30 PM PDT. I wonder who's still around at Allegro? A quick Skype gets hold of Steve Cooper, who with the other Allegroids diagnose within five minutes that the 3000 has got a memory error. The last digit of the error indicates which memory bank slot has the problem.

Okay, I'm not going to start climbing around the back of the rack at this time of night. I leave it until the morning, but at least I know what the problem is.

Making a UPS Light Up a 3000

Lightning_bolt_power_stripEditor's note: A recent message thread on the 3000-L mailing list and newsgroup reported on attaching an Uninterruptible Power Supply (UPS) to a 3000. The question came up when an MPE/iX manager asked about hooking up a UPS to an emulated 3000. While that is proof enough that the Charon emulator is working in the field, the question still covered HP's MPE hardware. More than five years ago Alan Yeo covered this ground for us in a lively and informative two-part feature.

Intrepid veteran developer Yeo of ScreenJet in the UK had a pair of HP 3000s felled, despite his sound strategy of using an Uninterrupted Power Supply in his IT mix (or "kit," as it's called in England). Here is Yeo's first installment of the rescue of the 3000s which logic said were UPS-protected. As Yeo said in offering the article, "We're pretty experienced here, and even we learned things through this about UPS." We hope you will as well.

New UPS, sir! or "Would you like fries with that?"

First of a two parts

"Smart UPS" now has a new meaning to me. "You're going to smart, if you're dumb enough to buy one" I guess this is one of those stories where if you don't laugh you'd cry, so on with the laughs.

By the end of this tale, you should know why your UPS may be a pile of junk that should be thrown in the trash. And what you should replace it with.

A Friday in early June and it was incredibly windy. Apparently we were getting the fag end of a large storm that had traversed the Atlantic after hitting the US the week before. Sort of reverse of the saying "America sneezes, and Europe catches a cold." This time we were getting the last snorts of the storm.

Anyway, with our offices being rurally located, strong winds normally mean that we are going to get a few power problems. The odd power blip and the very occasional outage as trees gently tap the overhead power lines. Always worst in the summer, as the trees are heavily laden with leaf and drooping closer to the lines than they are in the winter, when they come round and check them.

So this situation is not normally something we worry about. We are fairly well-protected (or so we thought) with a number of APC UPS units to keep our servers and comms kit safe from the blips and surges. The UPS units are big enough so that if the power does go out, we can keep running long enough for either the power to come back -- or if we find out from the power company that its likely to be a while, for us to shut down the servers.

We keep all the comms kit, routers, switches, firewalls and so forth on a separate UPS. This UPS will keep them running nearly all day, so that way we still have Internet access, Web, email and more, so can keep functioning, as long as the laptop batteries hold out.

What can a 3000 do to talk to a modern UPS?

SmartUPS
Michel Adam asks, "How can I install and configure a reasonably modern UPS with a 3000? I'd like to use something like an APC SmartUPS or BackUPS, for example. What type of signaling connection would be the easiest, network or serial?"

Jim Maher says

First you need to find out what model 3000. Listed on the back will be the power rating. Some of the older ones use 220V. Then you can match that with a proper UPS.

Michel Adam explains in reply

This HP 3000 is an emulator, i.e. a 9x8 equivalent or A-Class. I guess a regular "emulated" RS-232, or actual ethernet port would be the most likely type of connection. In that sense, the actual voltage is of no consequence; I only need to understand the means of communicating from the UPS to the virtual 3000.

Tracy Johnson reports

While we have three "modern" APC units each with battery racks four high, they also serve the rest of the racks in our computer room. Our HP 3000 is just a bigger server in one of those racks. Each APC services only one of the three power outlets on that N-Class. Their purpose is not to keep the servers "up" for extended periods, but to cover for the few seconds lapse before our building generator kicks in in case of a complete power loss.

As far as the UPS talking to our HP 3000 serial port, we didn't bother. Our APC units are on the network so they have more important things to do, like send emails to some triage guy in Mumbai should they kick in.

Enhanced, or not?

In the history department, Hewlett-Packard had its labbie heart in the right place just weeks before the vendor canceled its 3000 plans. We reported the following in October of 2001

HP 3000s will say more to UPS units

HP's 3000 labs will be enhancing the platform to better communicate with Uninterrupted Power Supply systems in the coming months. HP's Jeff Vance reports that the system will gain the ability to know the remaining time on the UPS, so system managers can know that the UPS will last long enough to shut down my applications and databases and let the system crash. Vance said that HP has scheduled to begin its work on this improvement—voted Number 8 on the last System Improvement Ballot—in late fall.

Late fall of 2001 was not a great time to be managing future enhancements for the 3000 and MPE/iX. The shortfall of hardware improvements and availability has been bridged by Charon. Adjustments to MPE/iX for UPS communication have not been confirmed.

Wayback: MPE's Computer Scientist Expires

Kick Butt Poster

Wirt Atmar conceived and lead The World's Largest Poster Project (shown above) with the help of hundreds of volunteers on a Southern California football field.

Ten years ago this week the 3000 community was reminded of its mortality. Wirt Atmar, founder of AICS Research and the greatest scientist to practice MPE development, died in his New Mexico home. Wirt was only 63 and demonstrated enough experience in the 3000's life to seem like he'd been alive much longer.

Atmar died of a heart attack in his hometown in Las Cruces, NM. It was a place where he invited everyone to enjoy a free enchilada dinner when they visited him there. He once quipped that it was interesting to live in a state where the omnipresent question was about sauce: "Green or red?" He gravitated to new ideas and concepts and products quickly. Less than a month after Apple introduced the iPhone, he bought and tested one, praising its promise even as he exposed its failures from the unripened state of its software to the cell signal unavailability.

If I go outside and stand under one specific tree, I can talk to anyone I want. In only one week, I have felt on multiple occasions like just heaving the phone as far as I could throw it -- if it weren’t so damnably expensive. The iPhone currently resembles the most beautiful cruise liner you’ve ever seen. It’s only that they haven’t yet installed the bed or the toilet in your stateroom, and you have to go outside to use the “facilities” — and that’s irritating even if the rest of the ship is beautiful. But you can certainly see the promise of what it could become.

He was not alone in predicting how the iPhone would change things, but being a scientist, he was also waiting on proof. The postings on the 3000-L mailing list were funny and insightful, cut sharp with honesty, and complete in needed details. A cruise through his postings on the 3000 newsgroup stands as an extraordinary epitaph of his passions, from space exploration to environmental science to politics to evolution and so much more. He was a mensch and a brilliant polymath, an extraordinary combination in any human.

Less than 24 hours before he died, Wirt posted an lively report on migration performance gains he recorded after moving an MPE/iX program to faster hardware running Linux. It was an factual observation only he could have presented so well, an example of the scientific practice the community loses with his passing.

One of the 3000 founders who was best known by his first name, Wirt was respected in the community for his honest and pragmatic vision of the 3000's history and potential, expressed in his countless e-mails and postings to the 3000 newsgroup. But alongside that calculating drive he carried an ardor for the platform.

Wirt was essential in sparking HP's inclusion of SQL in IMAGE, a feature so integrated that HP renamed the database IMAGE/SQL. In 1996 he led an inspired publicity effort that brimmed with a passion for possibility, conceiving and leading The World's Largest Poster Project (shown above) with the help of hundreds of volunteers on a Southern California football field. He quipped that after printing the hundreds of four-foot rolls of paper needed for the poster, loading them into a van for the trip to California represented "the summer corporate fitness program for AICS Research."

Long-time MPE licensees leave dates in dust

Date book
I went to a birthday celebration for Terry Floyd yesterday as part of a Super Bowl party. You may begrudge them the kudos, but congrats to the Pats, who once again executed like the MPE applications still running this week in businesses around the world. Not flashy, like MPE, but every day brings no surprises. That's a very good thing for enterprise computing, and always has been.

Floyd's turned 70 -- he’s the guy who started The Support Group here in Austin to serve MANMAN 3000 customers. One of those customers was in town to celebrate. Ed Stein spent years managing MANMAN at MagicAire, a Carrier subsidiary.

That corporation is still using MPE, even after Ed has gone. He’s moved into the interesting fields of independent support and consulting on MPE. He mentioned he's available to the community's 3000 owners looking for MPE talent. Along the way he's developed his experience on the prospects for keeping dates nine years from now in MPE.

It was Stein's intentions for prepare for the 2027 date keeping changes that led several companies to spin up services and strategies for date-keeping in 2028 and beyond. What was mumbled about in private became more public offerings and strategies. During a conference call among MANMAN managers late in 2017, Floyd and others talked about how much work it will be to keep dates straight in an era HP never planned for.

Stein says that in his travels though the community he’s still running into many a 3000 user who’s got no idea their OS will stop making accurate dates in less than nine years. He also made reference to Beechglen and its 2028 patch service. Like everyone else who's using HP's MPE source code licenses, Beechglen cannot sell a product to patch MPE/iX. HP was never going to sell permission to create patched versions of MPE/iX.

Seven companies paid HP $10,000 each to become the source code licensees about nine years ago. At the time, the 3000's operating environment felt like a long shot to feel its age and forget its date-keeping skills. The server was 18 years away from a date that no working MPE server would ever see, right?

Don't look now, but 2027 is gaining on the community. Floyd was one of several developers who identified the scope of the work to make an app like MAMAN ready for the year 2028.

Some customers will get readiness for 2028 by becoming 3000 support customers. Any support company using the MPE source must package the repairs and improvements they develop as support offerings. There are a half-dozen more companies with source capabilities for MPE/iX. Getting a relationship in place with them will be on some to-do lists for 2019. Even the companies without a clue about date keeping will eventually catch on to where the correct tomorrows are going to come from: solutions off the support bench.
