First of all, thanks for your work in the cam driver it really looks very promising and it solved the write append error with my TDC 4222, 'though I still don't have amanda running, but that's another story ;-) I made the following observations with the cam driver (980103 Snapshot) on a -current from exactly that date: On system halt or reboot it happens, that the following message is printed on the console multiple times: Timedout SCB handeled by another timeout.

That sounds like your SMP system is disabling interrupts during the last sync in shutdown. I've never seen this happen on a uniprocessor system. Ken Merry also runs CAM on SMP, but I don't know how recent his kernel is. >Here what dmesg tells about my system: >Additionally I have strange problems with my Tandberg SCSI streamer. >mt status only tells one density. > >Present Mode: Density = 0x00 Blocksize = 512 bytes >---------available modes--------- >Mode 0: Density = 0x00 Blocksize = 512 bytes >Mode 1: Density = 0x00 Blocksize = 512 bytes >Mode 2: Density = 0x00 Blocksize = 512 bytes >Mode 3: Density = 0x00 Blocksize = 512 bytes That's not strange at all. The "sa" driver is a rewrite but I haven't had time to add additional density or compression support. Those features should show up next week though. It looks like your tape drive does not honor the immediate flag for rewind commands. It should return an error when that happens instead of ignoring it.

It will be in the next CAM snapshot, most likely. So, just wait a little bit and we'll have support for it in CAM. Keep in mind that you'll have to run -current with the CAM patches.

I could probably scrounge up diffs for the version of CAM that wcarchive is running. It would probably be better to simply generate them again once Ken and I release the next snapshot for current. CAM depends on just a few features of current that could be brought into -stable. Perhaps after 2.2.6 is cut we can do that: 1) New timeout interface 2) New buffer queuing routines that handle the B_ORDERED flag. 3) Interrupt driven config hooks. 4) cam and vm software interrupt handlers 5) bus dma code. Getting even just a few of these pulled over would greatly simplify the process of getting CAM to run under stable. >I would certainly be happy to test out the CAM code in -stable as long as >it doesn't require too much programming experience.

This comes across my screen just as I'm wrestling with why the hell my new drive won't write a complete dump. I had an old IBM/Archive/Seagate DDS-2 drive (identified as Archive, not Python), which had been working great for almost a year. But lately it had been having problems, and I was using two tapes per backup on the NT box. So... I bought a refurbished Scorpion DDS-3 drive. It's awesome. Fast, holds tons on a tape. Only one problem -- it wouldn't write to my old DDS-2 tapes. So Seagate send me a firmware upgrade. Now the drive writes my DDS-2 tapes. Excellent! I only had about $300 worth of those I wanted to continue using. ;-) But now I'm getting these SCB resets/timeouts that everyone else is talking about. What the?! The drive works beautifully under NT. It worked fine the last time I tried it last weekend on NetBSD. But this weekend I wasn't able to get a complete dump with four different tapes (under NetBSD -- got NT backups just fine). The thing that people have been saying is wrong is that the drive identifies itself as being able to support tagged-command-queuing, but not actually supporting it? The thing is, my drive doesn't appear to be advertising such an ability (as far as I can see). It identifies itself as such: ahc0: target 2 synchronous at 10.0MHz, offset = 0xf st0 at scsibus0 targ 2 lun 0: SCSI2 1/sequential removable st0: drive empty So does anyone have an idea what the actual problem is? It would be cool if I could make this dude work. The system is a NetBSD 1.3 box, Adaptec 2940UW (7880), 64MB RAM, etc... ----------------------------------------------------------------------------- Michael L.

Sure, on Windows it's o.k. On a NCR 815 is's o.k. But I use a Adaptec 2940 now, and the HP1533A at the same SCSI bus works very well, and when the Python should be SCSI-2 conform, it has to work, too. I have two Adaptec (2940U and 2940UW) and a total of 8 devices, which are all running well, I've also tested more than 6 other SCSI disks, some 5 years old, no problem! The Seagate gives me a DOS (ASPI) testprog, which writes 5MB onto the DAT to check if it's working, and this is a very week test in my eyes! The hanging of SCB depends on the software you use. Tar seems to work most, dump gives somtimes probems, and a backup software with a highly optimized buffer queuing system seem to fail always!!!! However. Other people have the same problems, and I only want to bring them onto this path, so they have a chance to avoid this problems! Something else ridiculous?

Automatic hot standby, true, functional hot pluggable everything, full redundancy, IP switchover, self monitoring and error recovery, etc. We support RAID-0, RAID-1, RAID 5. Currently only up to 45 drives per array, but that will change too.

Multiple adapters on a single disk do not buy you much either. If adapter A decides to commit suicide and locks up the bus real good adapter B is still stuck. You want some kind of a bus isolator thingy. The company I work for (DEC) is releasing what is called SCSI hubs. These are multiport devices that can 'star couple' (for lack of a better terminology) multiple scsi buses, with each bus being electrically seperated. The larger hubs have a round robin arbitration builtin that makes sure that the host with ID 7 will not monopolise the bus to the device. All of this is based on a chip jointly developed by Digital and Symbios See www.symbios.com for more info.

The manual page for ch(4) currently states that noone has tested this device. Let it be known that it works :) Also the section on tape drives in the handbook (10.5.5.

Yes, you are right, my 'conclusion' was a little bit to general, but it's really a pain, afbackup is really a very good backup solution for smaller networks, or home machines. On the other hand, it's a pain with hardware that works/fail application dependent! I can't really conclude, but it seems to be a firmware problem, which Seagate is not willing to fix. So the only solution is to buy a HP DAT and never choose again a Seagate one in my case. Or to disable tagged command queuing for all devices, which is unresonable. How do you think such problems should be handled in the future? Do we need a fix on the FreeBSD device driver layer, or should we try to make 'preassure' (think this isn't possible) on Seagate???

I remember when we got the first 9 GB disks on SunOS systems. If you wanted to (low level) format it, you needed to change the definition of SD_FMT_TIME (default was a max of 2 hours) and recompile the kernel :-) So I would *not* be surprised if it takes 3-4 hours.

We use a lot of Quantum 9G drives here in our RAID systems, and the RAID controller takes about 2 hours to format one. As a matter of good practice, its probably a good idea to turn on a new drive in its working orientation, allow the temperature to stabilize, and then low-level format it. -- -- Karl Denninger (karl@MCS.Net)| MCSNet - Serving Chicagoland and Wisconsin http://www.mcs.net/ | T1's from $600 monthly to FULL DS-3 Service | NEW!

"As a matter of good practice" is it advisable to low level format a new SCSI drive at all? The only time I low level format a drive is as a last resort before crating it up and sending it back. But am leaning against even that. Last year we got a batch of (50) ST15150's. About 4 were problems and got low level formatted before being put into production use. Those lasted about 5 months. Can't really credit that stinky quality to Seagate as a stinky purchasing process resulted in drives that were handled too many times by the unknowing before finally being delivered into my caring hands. It was so bad we sent back a number of Kinsgton DE100 enclosures because they arrived bent. With HD's installed. And cables pinched. And termination still enabled on the HD (with 2 installed per box). -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.

I find that all versions of cdrecord after 1.6a1 do this, and this is due to a change in the software resulting in the FIFO being enabled by default, rather than needing to be explictly enabled, as in earlier versions. I see this on 2.2.2-RELEASE and 2.2.5-RELEASE - I'm using the worm device to drive a CW7502, Ricoh MP6200, Philips Omniwriter and a CDD 2000, BTW. Workaround (for cdrecord at least) is to set CDR_FIFOSIZE=0 in the environment or use '-fs=0' on the command-line, thus disabling the FIFO, apologies if this was already known (not subscribed to the SCSI list). It'd be nice if the SCSI driver were fixed 'tho - the whole idea of the FIFO is to enable on-the-fly mastering from NFS and other network filesystems.

I am having a terrible (and probably similar) problem with dying dump on the HP C1533A DDS-2 drive and Adaptec2940 and FreeBSD 2.2.2. See log below, after that it just almost-hangs (IP and presumably other parts of kernel work, but nothing more) till RESET. It used to happen every several months but recently I had this during 2 unattended backups in a row (separated by 3 days). What I could do about this? Will upgrade to 2.2.5 help?

Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi. Soon I'll upgrade my machine's disk sub-system from IDE to SCSI but I have some doubts. Which SCSI host adapter should I buy?

I also know that the ASUS adapter only supports SCSI-2 so I won't be able to plug a Quantum Atlas II (UW, SCSI-3) that I am planning to buy. Am I right? I've heard that from time to time some problems appear on the Adaptec driver and I've never heard anything similar about the cards with Symbios chips. But as I know that wcarchive.cdrom.com is running with 2 Adaptecs 3940 it shouldn't be a problem, right? I've also heard about the DPT host adapters, which are very fast trusting the company that produces these cards. Anyone with experiences on those? I might go with the inexpensive ASUS card now and buy a DPT latter instead of the Adaptec...

Which one performs > better? Both are intelligent bus-master cards. Justin Gibbs has put much more effort into the development of the AH2940 driver than I was able to spend on the NCR/Symbios driver.

Am I right? There is no SCSI-3, yet, no matter what the vendors try to make you believe :). Don't worry, the Atlas II will work just fine with either the Adaptec or NCR/Symbios cards. > I've heard that from time to time some problems appear > on the Adaptec driver and I've never heard anything similar > about the cards with Symbios chips.

(FYI this is for my home machine and > I can't spend to much money on it) If it is for your home machine, then the ASUS SC875 will be sufficient. The DPT offers support for all RAID modes, and surely is the better choice, once you approach 100GB total capacity :) Regards, STefan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message
