It booted and mounted filesystems, so it is not totally dead :-) * The release passed regresion and initial stability test on two of our machines. * Performance testing was performed only with the debug configuration, not the production (DPT vs. SENDERO). In 2.2, with 64 processes hammering a 6 device, 2 busses RAID-0 array (24GB) atriped 8k, we saw a very stable 900 tps. This is with st running 4k read - modify - write. Load average was about 50. Increasing the load beyond 256 processes pushed down the io/sec rate. Most likely due to cache starvation (only 32MB). * We did not test performance on 3.0 yet. We are still trying to break it. The reason for these numbers is not to brag, nor start a heated thread. But rather to demonstrate what to expect. I have been in contact with several people who were concerned about what numbers to look for. As you noticed, I do not publish (nor care :-) abount MB/sec. We use these systems for heavy database work. We only care about the number of transactions per second. BTW, we have yet to see a DPT exceed 1,700 transactions per second per controller. Highlights: * Justin's CAM interrupts were integrated into both 2.2 and 3.0 and seem to work fine. If (in the context of our testing method) higher SPL numbers indicate better throughput, then it went up drastically. We see, in 3.0, on 256 processes (plus a forever loop catting /etc/termcap over telnet session) LA of about 90. This is with only two disks on one bus. * We re-worked the critical sections to give as good a perfromance as possible. Accepting commands from the upper layer and scheduling it can be done in parallel with interrupt service. As a whole, the system is as parallel as can be (pending Justin's agreement :-). * There are no more calls to splhigh anywhere in the driver. * We added the spldlm as well, so when we release the dlm code, it will just drop in. * All the code to support Unix dptmgr is now in the driver. It received very superficial testing (if any). Please try to download this version and torture it. We would like to have it finalized before 7-Sep-97. This is it for now. Thanx for your support.

I will bounce any email I receive back to the freebsd-scsi mailing list in order to keep the discussion thread active. My Problem : I replaced a defective Micropolis 2217 1.7 Gig Fast SCSI-2 drive with a new ultra scsi Micropolis 4743NS. Since Ultra-scsi is "backwards compatible :-)", I never thought much about the upgrade. I.e. I did my "homework" and attempted to make sure that Ultra-scsi was supposed to be backwards compatible. So much for being naive. Current Hardware : 1742A EISA SCSI controller, (2) Maxtor 213SY 200M SCSI-1 drives, Exabyte 8200 tape drive, Archive 2150s, Toshiba XM3401TA cdrom drive, Micropolis 4743NS This is a 4 year old rock solid AMD5x86 133 Mhz system. until the micropolis 2217 died, this system could stay up for weeks until I powered down :-). Well ... lets get to the problem. Neither DOS, W95, or freebsd could talk to this drive. Cabling/termination is not the problem. I have tried all juxtipositions of internal/ external/end-of-the-cable/beginning-of-cable/terminated/non-terminated/ terminator-power-supplied-by-the-drive/terminator-power-not-supplied Nothing helped. I then disabled "syncronous negotiation" and "disconnection" for this drive only using the usual EISA configuration utilities. Now the Micropolis 4743 will talk reliably to DOS/W95 albeit at SCSI-1 like data rates. Freebsd will read data/partition info/etc from the drive. However, any writes to this drive will "hang" the scsi bus until I hit the reset button on the computer case. I can't even install Freebsd as the scsi bus locks up as soon as freebsd attempts to write the new partion/ slice info to the drive. Has anyone experienced a similar problem ? Any idea what steps I can take other than upgrade my motherboard/scsi-card/ vlb-graphics-card ? I currently lack the funds for that approach. - Steven Bartling P.S. The adaptec technical support folks were pretty amused that I would hook up an ultra-scsi drive to a 1742A. They stated : "Unless there is a jumper on the drive to force it to use SCSI-2 negotiation and data rates, there is no chance this ultra-scsi drive will work with the 1742A". How is that for encouragement ?

Yes, I have the same problem with an Atlas XP32150 and the Adaptex 1742A. The reason is the cache of the Atlas and the "slow" Adaptec. When the disc gets the blocks out of the cache, it's too fast for the controller and locks the SCSI-bus cause the first bytes are lost. The solution of this is to edit the mode page of the Atlas (getting this information cousts me 3 days of hard search in the newsgroups). So do the following: - get the dsp programm for dos to edit the scsi mode pages (you can get it from my anonymous ftp server). - edit the vendor specific mode page 0x25 (hex) - you get a byte-stream of 24 00 10 08 ..... a5 17 00 00 00 00 05 02 00 .... ^ ^ | Byte 0x05 Begin of Page (byte 0x0) - change the byte 0x05 (set bit 3) to 0x08 this enables a 15 mys delay for blocks out of the cache. - all runs fine! - NOTE: all the above fits for a 2 GB Atlas, but should also work for the 4 GB version. Be happy about this fast harddrive. Please e-mail on success.

How is that for encouragement ? If the 1742A is willing to "negotiate" an "ultra" transfer rate (i.e. any xfer period below 100 ns), then it is violating the SCSI-2 standard (to which this product was probably advertised as adhering). I would call it broken and demand new 1742A firmware. Unfortunately, this product is no longer manufactured and you probably don't have much clout with Adaptec. I don't know if pleading will help. It never worked for me.

It's an older Conner 540MB drive (CP3540), but this drive has been serving me well in another machine. I have it partitioned into a ~150MB /home partition, a ~32MB auxiliary swap partition, and two other partitions (one ~200MB and one ~150MB) that are currently not in use. Anyway, after I installed and partitioned this disk, I started to get these error messages both on my console (in bright white letters) and in my syslogs. These messages do not cause a kernel panic or something, and the system seems to run well despite them. Since seeing the first message I've been making hourly backups of my /home partition and comparing them, and all the data compares OK. Visually inspecting the files in /home shows no errors either. What could be going on here? Any ideas? I have already checked SCSI IDs and termination, and everything is A-OK. Please respond by e-mail if possible. Thanks!

[snip] I have a 5x86/133-P75 MB which also caused troubles with an Adaptec 2940 (a very old 2940). The failures were similar, altho mine were often fatal. The solution was to either 1) disable the external MB cache or 2) use write-thru mode on the cache rather than write-back. If the system would stay running, write back cache was a couple of % faster than write-thru. Write-thru was about 10% faster than nothing. Guess how its been running the past year? :-) Another system didn't like tagged queuing. You might disable that and see how it works. My tagged queuing problem system looks like: ahc0 rev 1 int a irq 11 on pci0:15 ahc0: aic7860 Single Channel, SCSI Id=7, 3/8 SCBs ahc0 waiting for scsi devices to settle (ahc0:0:0): "IBM DPES-31080 !t S31K" type 0 fixed SCSI 2 sd0(ahc0:0:0): Direct-Access 1034MB (2118144 512 byte sectors) (ahc0:3:0): "MAXTOR 7213-SCSI 0742" type 0 fixed SCSI 1 sd1(ahc0:3:0): Direct-Access 202MB (415600 512 byte sectors) Had no problem until I partitioned the Maxtor and started using it. Dmesg didn't indicate the kernel was going to use tagged queuing on the Maxtor. Kernel simply paniced and rebooted. But that's another story. -- David Kelly N4HHE, dkelly@hiwaay.net (hm) ====================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.

There is probably a FAQ entry 174x are somewhat notorious for being sensitive to fast glitches etc on the SCSI bus. For one thing it is really advisable to use the internal OR the external bus connector but not both. We had some fun with this in the original AlphaPC (the Jensen aka DEC 2000/300) I never had this particular problem myself on an Intel box with the 174x but I have to admit your disk is much newer/faster than the old stuff I use on the 174x based test box here.

Recently, I had all seven ID's taken up. 4 internal devices and three external ones. I have mixed and matched scsi devices up and down the scsi cable and I have never had any problems. Once, I had a bad passive terminator at the end of the external scsi bus, but that was easy to diagnose and fix. The 1742 bios was rev'ed a lot in the early days of the 1742. If you have an older board, you will experience lots of wierd behavior. Some devices will work only when they are the third device on the scsi cable, etc ... Adaptec cured most of those problems through firmware modifications. Try accessing their ftp site at ftp://ftp.adaptec.com. Their latest 1742 Bios can be found there. Use the 1742XAS.EXE version ( the 1742XA version is corrupted ). I replaced my bios a couple of years ago and life has been good to me until last week :-) - Steven Bartling From owner-freebsd-scsi Tue Aug 26 19:27:22 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id TAA27263 for freebsd-scsi-outgoing; Tue, 26 Aug 1997 19:27:22 -0700 (PDT) Received: from cyrix.com (cyrix.com [147.5.99.99]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id TAA27257 for ; Tue, 26 Aug 1997 19:27:12 -0700 (PDT) Received: from hydra.cyrix.com ([147.5.12.23]) by cyrix.com (8.7.1/8.7.1) with SMTP id VAA00993; Tue, 26 Aug 1997 21:26:59 -0500 (CDT) Received: from mega.eng.cyrix.com by hydra.cyrix.com (4.1/SMI-4.1) id AA13522; Tue, 26 Aug 97 21:26:59 CDT Received: by mega.eng.cyrix.com (SMI-8.6/SMI-SVR4) id VAA16641; Tue, 26 Aug 1997 21:26:58 -0500 From: bartling@cyrix.com (Steve Bartling) Message-Id: <199708270226.VAA16641@mega.eng.cyrix.com> Subject: Re: Freebsd2.2.2, adaptec 1742A and Ultra SCSI drive (fwd) To: proett@nas.nasa.gov (Tom Proett) Date: Tue, 26 Aug 1997 21:26:58 -0500 (CDT) Cc: freebsd-scsi@freebsd.org In-Reply-To: <199708261916.MAA19464@tailspin.nas.nasa.gov> from "Tom Proett" at Aug 26, 97 12:16:25 pm X-Mailer: ELM [version 2.4 PL25] Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk I got the dsp software from Lars' ftp site.

Micropolis has a "policy" of not releasing mode page information. Since the 4743NS works fine with newer scsi controllers ( I tested it with a 2940 ), their position is that it is an adaptec problem anyway. Adaptec folks state that they do not provide support for a controller that old. If they did, it would cost me $35.00 per phone call anyway. They have zero interest in modifying the 1742 bios in order to fix this problem. Do you think reducing the maximum possible value of the synchronous transfer rate will help ? The micropolis folks said that if I reduce the maximum allowed synchronous rate by modifying the controller card parameters, the drive should limit itself to the slower negotiated rate. I think that is absolutely true. However, I wonder if the "offending" scsi parameter will be modified as I reduce the transfer rate setting. I am having more fun everyday :-( Thanks, - Steven Bartling From owner-freebsd-scsi Wed Aug 27 13:47:34 1997 Return-Path: Received: (from root@localhost) by hub.freebsd.org (8.8.7/8.8.7) id NAA05254 for freebsd-scsi-outgoing; Wed, 27 Aug 1997 13:47:34 -0700 (PDT) Received: from styx.aic.net (Styx.AIC.NET [195.250.64.68]) by hub.freebsd.org (8.8.7/8.8.7) with ESMTP id NAA05215; Wed, 27 Aug 1997 13:47:00 -0700 (PDT) Received: (from ran@localhost) by styx.aic.net (8.8.5/8.8.5) id AAA03117; Thu, 28 Aug 1997 00:46:37 +0400 (AMT) Message-Id: <199708272046.AAA03117@styx.aic.net> Subject: problem with onboard adaptec 7880 To: freebsd-questions@freebsd.org, freebsd-scsi@freebsd.org Date: Thu, 28 Aug 1997 00:46:37 +0400 (AMT) From: ran@ran.am Reply-To: ran@ran.am X-Mailer: ELM [version 2.4ME+ PL31H (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@freebsd.org X-Loop: FreeBSD.org Precedence: bulk Hi, Hardware - Iwill's P55TU moderboard ( Intel 430HX chipset ) with onboard adaptec 7880.

Several adapters support SCSI_RESET to reset a specific target; you can get at it through "scsi_reset_target(sc_link)". You can start a unit with "scsi_start_unit(sc_link, flags)". In all cases you will then have to hope the system goes into the retry forever logic based on the "device in the process of coming ready".

They're also excruciatingly slow. Figure out how many tapes you might reasonably buy over the life of the drive and then see what the real cost is. DATs and Exabytes are usually a much better deal. I prefer Exabytes.

A/the Australian Archive (before they were bought) service agent (Peridata) qualified them on both the original head and the current replacement part. The wear characteristics are nonstandard, but appear to be within acceptable tolerances. It's possible that Sun either didn't bother to qualify the extended-length media, tried but decided the wear profile was "different" and therefore bad, or that the 2150 stopped being a mainstream product before it was worth the effort. > The drives aren't *that* robust- I'd say an old 9 track is > more robust, mechanical, not vacuum. It's data density is very low though. I wasn't comparing them to a 1/2" transport, but rather to a 4mm or 8mm mechanism.
