Cluster Booting - What they dont tell you.

by RodSmallwood＠mail.ediconsulting.co.uk

Hi As with many things the answer is very simple. The key is a program called LANCP invoked as $MCR LANCP on the boot server. It allows you to associate a name say VAX300 with a MAC address and add it to a database. It also allows you to set the name of the file to download and the root of the system. So far so good.... Now for the other half of the puzzle. How does the boot server listen for requests? Well there's an executable program call LANACP that is invoked by running LAN$STARTUP.COM Once running it services boot requests from across the network. It uses the data from the data base maintained by LANCP. It gives progress messages when a Node tries to boot. Once you have done that then, from the target system type >>>Boot EZA0: (ie the ethernet device on the target system) Lo and behold it downloads the file. It may well be the case that clusters use this system to boot satellite systems but you do not have to be a cluster to use it. We are not trying to make a cluster here. We are trying to boot a system that has empty disk drives. When I worked at DEC we were always warned that whilst .com files were very powerful things never to use them unless we understood what every line did. Further more each command line should be tested by entering it manually. I can now download a file to a target system just by typing Boot EZA0 at the >>> prompt. No Decnet, No Tcpip, No Clusters. The firmware on a VAX is independent of operating systems be they System or Network.

Never run a .COM file before looking to see what it does. cluster_config*_LAN*.com? You aren't meant to run that are you? At least, I've never done it that way. I've just attached a sample of invoking @SYS$MANAGER:CLUSTER_CONFIG.COM on my VAX. If you never at least entered the MAC address of your satellite VAX then you definitely ran the wrong procedure! I thought you had V6.2 - the LANACP stuff popped in V7 sometime, for those who didn't want to install DECnet-Plus. I would expect the procedure (if you run the right one) to do the right thing (but I don't have a VAX with that config around to check right now). One other thing: > DEFINE NODE VAX300/ADDRESS=08-00-2B-18-BB-D0/FILE=APB_061.EXE Before you go to far down this path, this is used to boot an Alpha from an InfoServer (or at least that's what I think it is, my infoserver isn't in use right now). So I don't think this is what you want. CLUSTER_CONFIG.COM should as a few questions, set a bunch of stuff up and then wait for you to boot your VAX 4000-300. There's no way that you are expected to delve this deep into this stuff if you run the right procedure.

Sun, HP "scrap" (???)

>Hi Joshua >It seems like you are the person to ask.

TBH, you usually dont handle such small amounts of salvage... to offset costs we were dealing with 1000lbs or more of scrap. Im not sure on the actual gold recovered, I didn't handle the precipitation of the gold from solution, i handled the grunt work of smashing up chips and stripping boards for the acid bath. So if your actually looking to make profit in this field you need to deal in scrap by the truckload Josh

Repairing the damage.

by RodSmallwood＠mail.ediconsulting.co.uk

Your server (the VAX 4000-200) does have to be running DECnet. Er no it doesn't and isn't. I attended a 1976 DEC engineering meeting where this was discussed. It just my personal memory has a long access time. Download and run was around long before Decnet was thought of. There's no Decnet or any other normal network involved. I am also beginning to suspect that the whole cluster thing is another GRH (Giant Red Herring) Whats actually happening is an old diagnostic tool is being used to download and run a program on a remote system to exclude the disk drives from the test.

Your server (the VAX 4000-200) does have to be running DECnet. MOP is not technically part of DECnet but the MOP-handling software is started as part of DECnet. (Actually, there is a another way with more recent versions of OpenVMS, using the LANACP stuff but I assume you haven't done this). Maybe I've missed a message or to, but does your VAX 4000-200 have DECnet (either Phase IV or DECnet-Plus) installed and running? It would be very unusual if it didn't, but it is possible to install without it. Antonio arcarlini at iee.org

Linux on SGI

by compoobah＠valleyimplants.com

Works marginally on certain limited hardware (IP30, IP22, IP32, IP27(Sort of)) NetBSD has slightly better hardware support. Support for graphics is marginal at best (Newport and some IMPACT). Go with IRIX, you'll be happier.

The 7805/lm309/lm323 reguire only 8V. All of the older 3 terminal regulators must have a 2.7V differential to regulate. The yabut, most of the S100 supplies were so poorly filtered that at any load the ripple voltage was excessive and didn't meet the minimum of 8V at the bottom of the ripple trough. A good example of that was the early Altair 8800 before MITS upgraded the transformer. With a 8A load the DC votage sat at 8.3V but the lowest voltage was 7.1V due to the AC ripple. Needless to say that ripple fould it's way to the 5V rail as the regualtor didn't have enough head room to regulate. The fix was a higher voltage transformer or much heaftier filter caps or both. > >The original backplanes were only 2 layer and couldn't handle the >current capacity.

Cluster Booting - What they dont tell you.

by RodSmallwood＠mail.ediconsulting.co.uk

************************************** Episode 1 *********************************** This is as far as I got to this morning: I am beginning to wonder if everybody is talking and nobody is listening. ************************************************************************ *************** * The target machine is not running anything except low level firmware !!! * * No DECNet No Tcpip No VMS - Nothing !!!! (It can't-disk drives inoperable) * ************************************************************************ *************** However after wading around in sea of online manuals I think am beginning to find out the things they don't tell you. Given that there has to be some form of communication between the Boot server and the target. Then what's left is this MOP thing. As you can specify that the boot device is the ethernet adaptor (EZA0: in this case) when you try to boot from the target system it must be sending out some kind of request packet with an ID attached. It can't be a node name or an IP address. There's no way tell it what they are!! What it does know, is its MAC address which is hard encoded into the interface. The server has to respond to the request (Remember No Decnet and No Tcpip available) somehow or other. So what is it that runs on the server does not use Decnet or Tcpip and can load images into the target machine? We can rule out @SYS$MANAGER:CLUSTER_CONFIG_LAN which expects Decnet and screw's up TCPWARE. I'm out of ideas at this point. Rod Smallwood ************************************** Episode 2 *********************************** More wading around in on line manuals ... Then some light .... The key is a program called LANCP invoked as $MCR LANCP It allows you to associate a name say VAX300 with a MAC address and add it to a database. To do this it uses the DEFINE command. DEFINE NODE VAX300/ADDRESS=08-00-2B-18-BB-D0/FILE=APB_061.EXE This refered to as a NODE. Now the Boot server knows about the target machine and its MAC Address. So far so good.... Now for the other half of the puzzle. How does the boot server listen for requests. Well there's an executable program call LANACP that is invoked by running LAN$STARTUP.COM Once running it services boot requests from across the network.

Hands up all of you who knew this and did not mention it. - Shame on you!!! 2. Hands up all of you that did not know this - Well, now you do!! 3. For MOP read LANACP. 4. Whats the name of the file to be downloaded from boot server to target to get VMS running on the target.? Lessons 1. Never run a .COM file before looking to see what it does. 2.

FYI: even the 2102LP parts were around 50mA each (512 *.05=25.6W) and the more common parts were around 80-100mA. Add regulators and that could easily total 40-60W of heat. Add a few IO, Floppy card and CPU and now your cooking. If the drives are in the box add fans accoringly. Dont forget the average 8V bus PSU was (in a decent box) rated to deliver that voltage at 25A (125W of 5V alone). Some boxes like the Compupro and Intergrand had CVCC transformers that typically ran hot as well. So the average S100 grate needed to move between 100 for a small system to as much as 500W of heat. >True, but with the advent modern chips like CMOS I see that >power consumption less of a problem.

A[2]=1. Any other order would not make sense. Algebraic equations do not read left to right. This causes a sense of ambiguity but shouldn't. Where it wouldn't be clear as to the result would be for the case: A = (5*N++) + (6*N++) But that only goes to show how poor this type of notation is for defining sequence of execution. This is why I still think RPN notation is much better for computer programming. This need not be a stack language like Forth. It is concise. Events happen left to right. No special rules. It isn't familar to what you learned in grade school but doesn't take long to grasp.

Repairing the damage.

by compoobah＠valleyimplants.com

Aren't VAXen similar enough to where you could drop the -300's disk in the -200, install VMS (or dup from the -200's system disk), reinstall the disk in the -300, key in the -300's licenses and AUTOGEN? I don't know as much about VMS as I'd like to, but I've had the disk from a 3100/76 up on a 4000/200 to test functionality, and is seemed to work fine.

New pcb design for S-100 prototype board available

by ragooman＠comcast.net

I've been working on a pcb design for a S-100 prototype board. I noticed a few people on the forums asking about this. I decided to make this since this is a big hobby of mine too(member-MARCH club). I based this design on a old prototype board I kept back from the S-100 days. It's made by Electronic Control Technology. Here's a link to the picture http://pghvintage.home.comcast.net/p...otypeboard.jpg <http://pghvintage.home.comcast.net/pics/S-100/s-100_prototypeboard.jpg> There were several different styles made before--each with their own advantages. This prototype board(in pic) has the rows in a vertical pattern to allow 300mil and 600mil DIP packages. It also accommodates 2 voltage regulators. Then there were some which only had a grid of solder pads to allow any arrangement of 300mil and 600mil DIP packages. I like to ask everyone what their preference might be in the arrangement of the solder pads, eg: vertical rows, horizontal rows, grid, etc. If I get enough feedback, I can include 2 different styles. It's not much work to alter the design. I have a panel setup to include 2 pcb designs at the moment, and it can be any 2 kinds of S-100 designs.

=== compaq SLT-286 power supply ===

by f5inl＠wanadoo.fr

Hi, I recently acquired an old Compaq SLT-286, but unfortunately, the power supply was not given to me. So I had to find a way of making it work by myself... I tried to connect a + 12 Vdc to the power connectors that normally are assigned to the battery. I put the ground on the most right pin, and a +12V on the most left one. The two middle pins were left unconnected, and of course, I removed the battery to avoid shortcuts. ( Ooops...when I say left/right, it's when the computer's screen is facing me, keyboard is removed, and the battery connector is located on the top/left corner :-) Like this : +------------------+ | **** | | ABCD | | | | | | | | | | | +------------------+ A : +12V D : GND BC : left unconnected With this, the computers boots normally on the floppy drive, but refuses to boot on the Hard drive. I obtain a 162 error message, inviting me to run SETUP. Then, I tried to run the compaq "setup.exe" diagnostic program, and I managed to see that my hard drive is perfectly recognized ! So, could anyone tell me il if I missed something ? Is my +12 Vdc connexion enough for powering the whole computer ? Actually I find very surprising that the battery's power connector has four pins, and I managed to do it work with only two :-( Thanks for your help, guys ! Sincerely, Fred.

SGI IRIX licenses?

by darin.lory＠gmail.com

Richard, As most of group have mentioned that you need a support contract or purchase the MIPSpro compilers (C, C++, F77, F90, Auto- parallelization, GNAT Pro ADA 95) specifically for your host which you intend to run on. The FlexLM license file is in /var/flexlm/ license.dat. You might want to check your IRIX workstation or server you are doing your IRIX install on, and see if you already have any licenses in this file. You might be surprised if your SGI might have previously been licensed. You can print out or copy this file for safe keeping. Upgrading within IRIX 6.5.x will not modify this file. You will need to contact your local sales office (http://www.sgi.com/ sales/ ) or call SGI at (800) 800-7441 or (650) 960-1980 if you need a license. You will probably need a quote for a 2CPU license (even if you are running on a 1 CPU workstation). Depending on the version of IRIX, it did place some freebie licenses in there. They also used to produce a "HotMix" CD with all the sample or open license software. I believe I still have a lot of these HotMix CDs from IRIX 5.3, 6.2, 6.3, 6.4. I would suggest that you setup a free Supportfolio account and see what you have access to. https://support.sgi.com/login SGI will give you a 30 or 90 EVALUATION license for any software, so you can try out the MIPSpro compilers and see if you want to go for the cost of the software http://www.sgi.com/support/licensing/ . The MIPSpro compilers really take advantage of the SGI architecture and IRIX, more so than GNU software. But depending on what you need, GNU compilers might be fine for what you are doing. Some of the Development tools (http://www.sgi.com/developers/ technology/irix/tools.html more info) you can download and may get a PERMANENT license for ANY host (HOSTID=ANY in license.dat). You can download most of the available software (except compilers) at http://www.sgi.com/products/evaluation/ It will note what type of license (like FREE or no license needed). Most of the stuff that might interest you are things like Cosmo Player, Open Office, Message Passing Toolkit 1.9 and Parallel Virtual Machine-PVM (I have PDF version of non-copyright books on PVM and MPI if you need them), Java (1.4.1_06 which is NOT DST compliant without a patch that they created from a bug report I placed, but should be available from Supportfolio). If you don't want to purchase the MIPSpro compilers, the GNU compilers are available. All Freeware software is at http:// freeware.sgi.com/ and all the manuals/books are at Techpubs in HTML and PDF format http://techpubs.sgi.com . C++ coding standard for IRIX and GNU C++ are at http://www.sgi.com/tech/mlc/docs/cc-coding.ps I suggest if you can get it, to install IRIX 6.5.22 or later. IRIX 6.5.30 is the latest. You can then install the DST (Daylight Savings Time) patch for IRIX 6.5.22 to 6.5.30 (new patch for 6.5.30). IRIX 6.5.2f to 6.5.21f (f for Feature set, m for maintenance) require you to download a new tzdata file (from tp://elsie.nci.nih.gov/pub/), modify /etc/TIMEZONE, and run the zic compiler for your locale. I can email you or provide you all this information if you need it. I also wrote TONS of documentation for work on installing IRIX, startup/shutdown procedures, backup procedures and I can send that to you also. I have expertise on IRIX 4.0, 5.3, 6.2,6.3,6.4 and 6.5.x on all kinds of MIPS and SGI hardware from MIPS workstations, SGI Personal IRIS, Indys, Indigos, O2s, Octanes, Crimsons, and Origin servers (200, 300, 3800). But I only have Indys, O2s, Octanes, Origin servers, and maybe an Indigo Impact for me to use. Most of everything else was upgraded or replaced. Let me know if you need anything. I'd be happy to help you out. -Darin

Hi The abortive attempt to cluster the two Vaxes and copy data has left me much further back than when I started. The network and terminal server connections are gone because I can't start TCPWARE up. It complains about a license and and something called NETCU (What the hell is that?) and aborts the loading of TCPWARE. Lesson learned,= the boot from a cluster server idea is flawed and can damage an existing setup. Its probably one of those things everybody has heard about but never actually done. Back up did somebody say Back up.? The whole reason I attempted doing it this way is because despite the fact that both systems have TK 70 tape drives when attempting to do a backup on the -200 it keeps telling me the tape is write protected which it isn't. I'll try to sort that one out to-morrow. Rod
