You'd be better off getting one of the NCR/Smybios based cards. The 2920 is not a busmaster card...

If you're ever bored :) you might want to chew on this one: System: P5-150, 512 kB L2 cache, 128 MB EDO RAM, FreeBSD 2.2.1R 2940UW (SCSI ID 7) - TOSHIBA 5701TA (SCSI ID 4) - QUANTUM XP34550W (SCSI ID 1) - CONNER CFP1080S (SCSI ID 0) 2940 (SCSI ID 7) - OLYMPUS MOS330 (SCSI ID 6) How to repeat: run concurrent I/O to XP34450W and MOS330 at the same time. Symptom: With heavy disk activity on both the OD and the harddisk, random lockups occur. Just copying data from OD to harddisk to (or the reverse) works fine, but the machine freezes solid after a while if you put more load on the harddisk.

I don't particularly care about busmaster, booting off the card, etc. All I'm ever planning to drive with this card is a CD-ROM and a Jaz drive, and I don't particularly care about high performance on these devices (the JAZ is only used for archival storage, and I don't care if it takes 8 seconds vs. 4 to move a .tar.gz file onto it, etc.). I've got (E)IDE HD's in my system that I'm perfectly happy with. Anyway, it's only a 5x86-133. If I ever upgrade to my Pentium II dream system, I'll surely have a bit more cash to play with, so then I'll get the 2940 for performance. Right now I just want something that works. Besides, I have NOT been able to find any NCR/SymBIOS cards. Well, I take that back: I've seen a LOT of cards but I'm not sure what chips they have in them, and when I ask, all I get is "Duuuhhhhh...?" So I guess my original question stands: is the AHA-2920 supported by any version of FreeBSD (or any patch thereof)? And I have another question to add: I know NCR/SymBIOS chips are used in a lot of 3rd-party cards? Can anyone give me a list of which manufacturer/models have the NCR/SymBIOS chip in them?

With your permission (I hope :-), I am forwarding this question to the FreeBSD-SCSI group, too. A patch against current can be found in ftp://nomis.i-connect.net/crash. Pick up the patch of the 13th, not the 14th (which is buggy). You can find a boot floppy in the various release builds in /FreeBSD, in the usual place. The source should have been committed long ago and is quite stable. Maybe in the next few days. No, there is no web page as I do not know how to create one. Too lazy to learn too :-( The current driver supports all the DPT PCI controllers shipping currently, does not support the software RAID (so you cannot span controllers and cannot create multi-driver RAID-1. These can be acomplished easily and probably almost as well with ccd. Initial support for multi-initiator and distributed/shared I/O is present and this support will increase daily in the next week or two. There is an Alpha release of a DLM included in the patch, but the connection between the two is still missing. Thsi iwill be closed in the next few weeks. The driver (aside from the MI code, is rather stable, went through extensive code review and is capable of about 1,742 I/O operations per second per HBA, when talking to a PM3334UW.

A slow processor needs busmaster DMA much more than a faster CPU. ;-) The point is that PIO transfers bind your valuable CPU resources that could be used otherwise simultaneously when using DMA. > ever upgrade to my Pentium II dream system, I'll surely have a bit more > cash to play with, so then I'll get the 2940 for performance. Btw., it's an old but equally wrong hype that something like an AHA2940 were faster than the NCR chips. (Of course, assuming similar environment, i.e. compare the NCR 53c810 with a plain AHA2940, and the 53c875 with an AHA2940UW.) The Adaptec is way more expensive (and has some other interesting features like on-board memory to remember the device configuration), but it's not faster. The worst point of the NCR is indeed the BIOS support, but you'd be surprised to find out how many BIOSes actually do support it, without announcing this fact anywhere. A colleague yesterday confirmed this again, for a plain standard Award BIOS. > So I guess my original question stands: is the AHA-2920 supported by any > version of FreeBSD (or any patch thereof)? There's some rather preliminary support on the FreeBSD 2.2.5 CD-ROM, in /xperimnt. The driver leaves quite a number of things to be desired (in short, it doesn't fit quite right into the FreeBSD tree structure, since it migrated from NetBSD via the PAO distribution), so i could not make up my mind to import it into the FreeBSD tree.

Together with the other SCSI complaints, i would first look for a misterminated (or mis-powered) SCSI bus. Make sure only the ends of the chain get terminators, and avoid having anything else than the SCSI controller feeding termination power. (It's in theory acceptable to have more than one source of term power, but in practice, it has proven to lead to occasional problems. Disk spin-downs belong to this problem category, from my experience.) -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-) From owner-freebsd-scsi Thu Nov 20 06:59:57 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id GAA09561 for freebsd-scsi-outgoing; Thu, 20 Nov 1997 06:59:57 -0800 (PST) (envelope-from owner-freebsd-scsi) Received: from seabass.progroup.com (catfish.progroup.com [206.24.122.2]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id GAA09556 for ; Thu, 20 Nov 1997 06:59:52 -0800 (PST) (envelope-from craig@tuna.progroup.com) Received: from ProGroup.COM (tuna.progroup.com [206.24.122.5]) by seabass.progroup.com (8.7.5/8.7.3) with SMTP id GAA05020 for ; Thu, 20 Nov 1997 06:59:13 -0800 (PST) Received: by ProGroup.COM (SMI-8.6/SMI-SVR4) id GAA04146; Thu, 20 Nov 1997 06:58:44 -0800 From: craig@tuna.progroup.com (Craig W.

While Onsale claims the drive has a 5 year warranty, they say its handled thru IBM. Forgot if there was an "OEM" mark on mine. Not sure how warranty will be handled but I printed their web page with the claim, and my bid listed, and should have good grounds for false advertising if I'm denied warranty service. After you get yours, read the scsi(8) manpage an set the WCE (Write Cache Enable) bit.

Couple of questions: 1. If there IS a freebsd driver, where would I find it? 2. Can you explain to me how the RAID 5 works on the DPT? For example, how is recovery done upon failure of one of the drives? 3. In RAID 5 mode, how does the diskspace work out? What I mean is how do you calculate it? It's easy for RAID 0 (add the drives), RAID 1 is the total divided by the number of mirrors. But in RAID 5 what's the calculation? If I use 3 2.5Gb drives, how much total space would I have? thanks Ricardo On Thu, 20 Nov 1997, N.

The MicroPolis is a full-height drive. It is in a case with space for 2 such drives. The case DOES NOT need to be terminated. The above setup has worked for months and months and months (April). I now have a new-to-me Seagate ST-31230N. I ran 'verify media' on it, and it came up just fine. I installed a DOS partition on it (10 megs) and FBSD 2.2.5 off the CDs. It works FINE but only if I remove the other Seagate drive and disconnect the external devices I cannot seem to put the new Seagate in the chain anywhere without causing system panics and SCSI timeouts. I have tried to put it between the Adaptec card and the CD-ROM (inside the tower) and in the external case with the MicroPolis. The Adaptec is set to DISable Termination. I am guessing that this is a termination problem somewhere, but WHERE? How do I fix it? I've got the spec sheets for all 3 drives but don't really know how to read them....

It seems that some (not all) cable vendors do not understand the specification, describing their cables as SCSI-2 compliant when they are not. A common misconception is that SCSI-2 means a high-density connector. In fact, there are several connector options.

A PM3334, will perform this duty automatically based on the hardware hot swap signal if implemented in the SCSI backplane.

Marketing and technical accuracy have nothing to do with each other. You can also buy, "SCSI-3" cables. Yet last time I looked everybody was still arguing about what SCSI-3 was.

Don't you know that when you say something like that, somebody like me is going to come out of the woodwork? I removed the internal SCSI harness from an external Exabyte 8500C a while back and replaced it with what's commonly called "SCSI-2" connectors and harness. What I removed was exactly the 3-row DB-50 connector you describe. And don't you *know* it came off a Sun 4/470? I recycled the DB-50 connectors by putting them to use connecting (8) 8" IPI drives to an SGI Crimson. 19.5G and lots of heat! Digging thru our SCSI cable box the other day I found external cables with that DB-50 on one end and "SCSI-2" on the other. And found another with a modern 68-pin SCSI connector on the other end. Naturally I couldn't find the cable I was looking for. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
