For me, the cost of the media is awfully important. We just got our first Seagate Scorpion DDS-3 tape drives at work. Seagate DDS tape drives have been very reliable for me.

I've been using an 8700 that's worked flawlessly for me in NetBSD. It should do at least as well in FreeBSD. I worked out that the cost for an 8700 was lower than a Travan after buying 15-20 tapes. BUYCOMP usually has several different 8mm tapes for $3-$5 ea.

According to the FAQs, newsgroups and mailing list searches and brief code studies, the situation is as follows: - Regular operation works fine. dpt_scsi.c was ported to CAM. The version in the FreeBSD source tree is the most up-to-date compared to those on ftp.simon-shapiro.org. - The /dev/dpt0 control interface, defined in dpt_control.c, is not yet ported to CAM. So there is currently no way to remotely query even the failure state of the disks from within FreeBSD. Is this true? If yes, is there a timeframe when dpt_control.c will be ported to CAM? I did some dirty hacking myself which made it partly work. In particular, the dpt_* utilities for for most parameters.

How is the magneto optical support > in BSD? Not much support needed. There used to be an od(4) driver previously, but i believe CAM can now handle those drives well enough as plain disks. Regarding ultimate reliability, my experience tells me that a DLT has a lower failure rate than a MO. I've seen MOs go to hell, where you couldn't read the data again from the medium.

As far as I know, no one is working on porting that driver at the moment. One thing to keep in mind is that there isn't much in the way of FreeBSD-specific documentation describing the interface between the transport layer (xpt) and the HBA drivers. There are three things to look at: Justin's paper on CAM from USENIX '98: http://www.FreeBSD.ORG/~gibbs/ The CAM-2 and CAM-3 specs: http://www.symbios.com/x3t10/drafts.htm#SWLAY And there are of course a number of other drivers that are available as examples. If you've got specific questions, you can probably ask Justin Gibbs , since he wrote most of the bottom half of the CAM code.

I've been thinking about them for backups recently and they look quite attractive. A DVD drive, which you can use for all the other CD and DVD formats is £599 in a mag here and a 5.2Gb DVD-Ram is only £26.85. Possibly a little pricey compared to the lower end tape solutions and not the storage capacity of the higher end DLT but as an in-the-middle solution it looks quite attractive at that price. Seems like it would blow a Jazz disk out of the market and given some time to mature it might start threatening the lower end super-floppy type devices. CDROM drive prices have certainly plummeted since they came out, if DVD technology does the same this is going to look like a very attractive device. I don't know how one of these DVD-Ram media would stack up against tape when it comes to longer term storage but I suspect very well. In terms of performance I suspect it's much better than tape. As you can probably see, I've not looked into this much, DVD-Ram just recently caught my attention and the price/Mb of the media really surprised me. Paul.

That is quite odd. The timed out while idle message indicates that a command timed out, and the device didn't respond. You said that this happens both with *and* without the DAT drive connected? If that is the case, that means that the driver is getting confused somehow, and must think that something is responding to selections. (which shouldn't be happening, since there is nothing on the bus!!) I could come up with a theory if it only happened with the DAT drive installed, but this is strange. It could be a sequencer bug. I'll forward this on to Justin and see what he says...

Writting an > automounter that will automount cd-roms, possible floppys, zips etc. In a word: No. The reason that CAM does not detect media insertion, and events like that, is that there are very, very few devices that support AEN. AEN is Asynchronous Event Notification. It allows a device on the SCSI bus to send a message to another device, notifying it of a specific event. To support AEN, the device in question must be capable of being an initiator, as well as a target. Also, the controller and controller driver must support target mode. The only real way to detect media insertion, etc., is to continually probe for it. I think this is how things like mediad on SGI boxes work. They probe the drive every so often to see if something has been inserted. I doubt that ATAPI CDROM drives support anything like AEN that would allow you to detect media insertion without polling. One thing to keep in mind is that media probe capability will likely be a feature of a revamped DEVFS implementation, if it appears at some point. In fact, Julian had something of the sort working last summer as part of his DEVFS/SLICE stuff. Since the media poll routines will block, they'll probably need to be implemented as either a kernel process/thread, or a userland daemon that polls for media insertion. This is obviously an area that would need some thought/design for a good implementation.

Next time you perform some operation on the device, it will respond with a Unit Attention, thus telling you its medium has been changed.

Hmm, what kind of QIC-150 drives? The old Wangteks are built very cheaply. OTOH, i didn't have any bad experience (so far) with Tandberg QIC drives, and there are some three drives (TDC 4222, 2.5 GB + compression) around me doing nightly backups for years now. QIC media have a good lifetime (unlike DAT), and it's not a problem to use the very same tape every night for a year or more. (Two of the three drives are used in an operatorless environment where it's simply impossible to change the medium on something like a daily or weekly basis.

I replace the tapes every two years, which means that the tapes are used 20 times, plus a few times for restores. The drives wear out before the tapes :-( I think if HP's information about lifetime of the tapes is true, that we could repeatedly reuse the same tape every day and it would still have some life left at the time we see the drive fail. } > I've also had problems with media } > interchange between QIC drives. } } Sounds like you've got a broken or worn-out drive.

QIC Tandberg are really good drives. I used the 525 Mb variant succesfully and now I also own a 4200. Don't use it often, I like my DLT for doing the regular backups. Archive drives are also reasonable, but not as good as Tandberg.

I seem to remember a small sheet of paper saying it's not recommended to mix basic-length and extended-length tapes.

Umm, you can't. Writing to CD-R or DVD drives is very different than writing to MO drives. Even if you change the probe routine in the od driver to recognize your DVD drive, writing to the drive probably won't work properly. I suggest that you try cdrecord, and see if you can write a DVD that way. You can probably stick a cd9660 filesystem on the DVD.

Note that I've seen QIC tapes fail fairly rapidly if not stored fully rewound; the tension pulls the tape over the index holes and causes the layer or two immediately above the holes to deform, making several sets of tracks unreadable at that point. Aside from that, I tend to concur; if you want the data to last any length of time, 9-track or QIC is about the best you'll manage. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message From owner-freebsd-scsi Wed Feb 3 13:03:02 1999 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id NAA21948 for freebsd-scsi-outgoing; Wed, 3 Feb 1999 13:03:02 -0800 (PST) (envelope-from owner-freebsd-scsi@FreeBSD.ORG) Received: from silver.sms.fi (silver.sms.fi [194.111.122.17]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id NAA21926; Wed, 3 Feb 1999 13:02:55 -0800 (PST) (envelope-from pete@silver.sms.fi) Received: (from pete@localhost) by silver.sms.fi (8.8.8/8.7.3) id XAA22957; Wed, 3 Feb 1999 23:02:41 +0200 (EET) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Date: Wed, 3 Feb 1999 23:02:41 +0200 (EET) From: Petri Helenius To: "Kenneth D.

Well, you can certainly try it. I think it would be easier to just use the CAM cd driver, though. It should already support writing, and it'll attach to your drive by default. I'm not sure, though that the cd9660 filesystem code can support writes. You may have to use a standard ufs filesystem on the CD for that. I just tried a few experiments to see if I could get a cd9660 filesystem to mount read-write (using the vn device), and I wasn't able to get it to work.

Sounds ok. What really tensions the tapes is when you can't keep the tape streaming, so start/stop operation.

There's another reason why i'm always rewinding the tape after operation. If for some reason the machine reboots, or a SCSI bus reset happens, the tape will be rewound. Thus, the backup script needs to position to the end anyway. So rewinding the tape is the best position to start from each day. the tension pulls the tape over the index holes and causes the > Aside from that, I tend to concur; if you want the data to last any > length of time, 9-track or QIC is about the best you'll manage. DLT should be similar. Too bad, i've got an old 9-track drive that was once working on a Unisys machine. So far, i haven't gotten its SCSI interface to say a single `beep' on the bus. The tape transport itself seems to work OK. Sure, the thing doesn't have any usable capacity these days, but it's a historical object. -- 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. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message From owner-freebsd-scsi Wed Feb 3 22:20:49 1999 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id WAA22499 for freebsd-scsi-outgoing; Wed, 3 Feb 1999 22:20:49 -0800 (PST) (envelope-from owner-freebsd-scsi@FreeBSD.ORG) Received: from sax.sax.de (sax.sax.de [193.175.26.33]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id WAA22488 for ; Wed, 3 Feb 1999 22:20:47 -0800 (PST) (envelope-from j@uriah.heep.sax.de) Received: (from uucp@localhost) by sax.sax.de (8.8.8/8.8.8) with UUCP id HAA12446 for freebsd-scsi@FreeBSD.ORG; Thu, 4 Feb 1999 07:20:46 +0100 (CET) (envelope-from j@uriah.heep.sax.de) Received: (from j@localhost) by uriah.heep.sax.de (8.9.1/8.9.1) id HAA06754; Thu, 4 Feb 1999 07:19:42 +0100 (MET) (envelope-from j) Message-ID: <19990204071941.31271@uriah.heep.sax.de> Date: Thu, 4 Feb 1999 07:19:41 +0100 From: J Wunsch To: freebsd-scsi@FreeBSD.ORG Subject: Re: od driver Reply-To: Joerg Wunsch References: <14008.47444.55701.124427@silver.sms.fi> <199902032131.OAA40124@panzer.plutotech.com> Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii X-Mailer: Mutt 0.88 In-Reply-To: <199902032131.OAA40124@panzer.plutotech.com>; from Kenneth D.

R/W mounting is probably not that big of a problem, but the entire driver is IMHO not written with the idea in mind that data on the medium might change at some point while the medium is mounted. So this will probably end up in a rewrite of the cd9660 driver. -- 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. ;-) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message From owner-freebsd-scsi Wed Feb 3 22:43:21 1999 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id WAA24810 for freebsd-scsi-outgoing; Wed, 3 Feb 1999 22:43:21 -0800 (PST) (envelope-from owner-freebsd-scsi@FreeBSD.ORG) Received: from sasami.jurai.net (sasami.jurai.net [207.153.65.3]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id WAA24796 for ; Wed, 3 Feb 1999 22:43:16 -0800 (PST) (envelope-from winter@jurai.net) Received: from localhost (winter@localhost) by sasami.jurai.net (8.8.8/8.8.7) with SMTP id BAA03446; Thu, 4 Feb 1999 01:43:07 -0500 (EST) Date: Thu, 4 Feb 1999 01:43:07 -0500 (EST) From: "Matthew N.

So > this will probably end up in a rewrite of the cd9660 driver. The ISO9660 filesystem is not designed for writing, but only for static data. It doesn't even support fragmentation of files or appending to an existing file, AFAIR. So it's not really feasible to add R/W support to the cd9660 driver. For a DVD-RAM, the best thing right now is probably to use a UFS, since we lack support for the native DVD-RAM filesystem specification (I don't remember its name).

DLT media is better than QIC media. Officially they state a 20 year shelf life, off the record 30 years.

I have both in use...my root drive, and the CD I'm trying to read from, is on the 50pin..my new 4gig is on the 68pin. I can access both the root (obviously) and the 4gig drive, just tosha fails on the CD... %tosha -iq error sending SCSI command: Input/output error the kernel is "fresh" as of about 30minute ago or so, figured I should bring the 3.0S machine up to date before adding more data...makes no difference... Trying to follow things through a little further, I just shut down and removed the second bus (68pin)...now the CD works again.

The Sony reports 20Mhz (FAST-20) speeds, and you're mixing a wide and narrow bus. They aren't separate busses, and I'd have my doubts about this working well. I don't remember off the top of my head whether the AHA driver reads NVRAM settings, but try and dial down the Ultra rates- it really isn't going to work well in this configuration.

References: Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Be sure to turn off the termination on the Adaptec itself when you have both the 50-pin and 68-pin cables attached to it. You should also be aware that if you're using both the 2940UW's internal connectors that you can't have anything connected to its external connector. Also be sure your 68-pin drive and whichever drive is at the end of your 50-pin cable are both terminated. hope this helps, Eric The Hermit Hacker wrote: > > Further to my last, slightly more details to work from... > > Attached is from /var/log/messages, basically what gets spewed out when I > type 'tosha -iq'...and dmesg.boot > > A few extra details that I just clued into.

I've made (hopefully) the last sets of changes for a while. I fixed the problem with the end of tape stuff in that I went back to the 2FM @ EOD rule (that works for all but QIC tapes). I don't agree with this way of marking EOD (except for Reel tapes) but because tcopy depends upon it and 3rd party software expects FreeBSD to terminate tapes with 2FM, so be it. There are still unhappy things that may occur, but hopefully this meets the minimum for now. I want to move on to what the 4.0 release will have (I plan to adhere to the TapeAlert specification). -matt To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-scsi" in the body of the message From owner-freebsd-scsi Fri Feb 5 15:32:51 1999 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id PAA19689 for freebsd-scsi-outgoing; Fri, 5 Feb 1999 15:32:51 -0800 (PST) (envelope-from owner-freebsd-scsi@FreeBSD.ORG) Received: from silver.sms.fi (silver.sms.fi [194.111.122.17]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id PAA19611; Fri, 5 Feb 1999 15:32:07 -0800 (PST) (envelope-from pete@silver.sms.fi) Received: (from pete@localhost) by silver.sms.fi (8.8.8/8.7.3) id BAA16671; Sat, 6 Feb 1999 01:31:49 +0200 (EET) MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Date: Sat, 6 Feb 1999 01:31:48 +0200 (EET) From: Petri Helenius To: freebsd-scsi@FreeBSD.ORG CC: freebsd-stable@FreeBSD.ORG Subject: DVD-RAM X-Mailer: VM 6.43 under 20.4 "Emerald" XEmacs Lucid Message-ID: <14011.32492.892285.496123@silver.sms.fi> Sender: owner-freebsd-scsi@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org I got my DVD-RAM partitioned and labeled ok after enabling the dual-LUN mode on the drive but when I try to run newfs to the drive, I get the following error messages on 3.0-stable: (built earlier this week) Would anybody have an idea what's going on?

You almost certainly have a cabling or termination problem. The parity errors are a very good indication of that. You should probably have the termination set to 'automatic', or high on, low off, and of course make sure that both ends of the bus are terminated. If that doesn't work, I would try replacing the cables, checking for bent pins on various connectors, etc. Also, you might try moving the cables away from the power supply.

Yes, I think so. This is because the devices on the 50-pin part of the bus can't terminate the high data byte. So, "high on, low off", or automatic termination should work. The former is probably the safest alternative, although automatic termination should work just fine.

You won't be able to use camcontrol for most things without it. Second, someone hasn't read the camcontrol man page. The -f option to the defects command is to specify the defect list format. To format a disk, you would do something like this: camcontrol cmd -n da -u 0 -t 3600 -v -c "4 0 0 0 0 0" The -t argument sets the timeout in seconds, you may need more time, depending on what kind of drive you have. > On Sat, 6 Feb 1999, David O'Brien wrote: > > > You will get more mileage by discussing this type of thing on > > freebsd-scsi@freebsd.org > > > > > > > > Is there ``/sbin/scsiformat''?

Sorry to respond to myself, but as the error message below indicates, it is either because the pass driver isn't in the kernel, or because da0 doesn't exist. In your case, it's the latter. That's because the da driver couldn't attach because of the fatal error it got back from the read capacity command. > > On Sat, 6 Feb 1999, David O'Brien wrote: > > > > > You will get more mileage by discussing this type of thing on > > > freebsd-scsi@freebsd.org > > > > > > > > > > > Is there ``/sbin/scsiformat''?
