Insufficient Info !

By now you will have seen a posting by me on this list, asking for info
on other cards, but offering _card component_ & _DIP header_ geographical 
layout so people have a chance to compare & match,

If you provide this info I may be able to help, as I have some old 8 bit 
full length sheets here, my card is 16 bit I think,
but a friend's is 8 bit I recall.

It runs a drive that answers
	wt0 at 0x200-0x203 irq 9 drq 1 on isa
	wt0: type <Archive>

Anyone who previously didnt look at the mime encoded gif, thinking:

Hi, all,

  Does FreeBSD 2.1.5-RELEASE have support somewhere for PnP
modems/hardware?  I have a non-PnP BIOS, BTW.

  TIA,

I'm assuming that, since you're writing in English, and WRT what you
say below, you'd like me to copy -hardware on this one, so I'm doing
so.

Yes, that's correct.  It was one of the problems I was thinking of,
too.  Let's wait for his reply.

Now there's some interesting information.  For some reason, they don't
mention this in the data sheets.  While I'm on the subject, what do
you know about the Archive 4586 NP tape changer?  I've just bought one
of these, and so far (not really far enough to know), I'm happy.  I
will report.

This, again, is interesting information for a number of reasons:

1.  I haven't seen any information that the drum isn't covered.  Maybe
    I just forgot it.  Unfortunately, I can't find any warranty
    information.

2.  The time you quote is *horribly* short.  How can this compare with
    the documented MTBF.  According to HP, the MTBF for the 35470A is
    50,000 power-on hours, and the MTBF for the C1533A is 200,000
    power-on hours.  In each case, they're assuming a duty cycle of
    12% (which I exceed), so the real MTBFs would be 6,000 operating
    hours for the 35470A or 24,000 operating hours for the C1533A.

    My backups typically write a whole tape and take about 8 hours per
    day.  Tonight's backup started at 9 pm and finished (after a
    verification read) at 5:07.  That's a 33% duty cycle, which would
    have the 35470A die after about 2 years.

    If we took your figures, they should die after about 4 to 8
    months, which is pretty much my experience.  The only thing is,
    this is the first I have heard of the figures.  There's nothing in
    any documentation I've seen which suggests that the drum is a
    high-wear component.  Laser printer documentation does indicate
    that the print drum requires frequent replacement, for example.

> I've read about the new high capacity QIC drives, which offer

Interesting possibility.  The oldest component I still (sometimes) use
in my system is my old Tandberg TDC 3800, now about 5 years old, which
has never given me any trouble.  The current TDC 4222 can apparently
store 2.5 GB (5 GB with hardware compression) on a DC9250 tape (which
costs DM 48 or $32).  They also mention a 13 GB cartridge (DC13GB) for
DM 127 ($83), but it's not clear what it's supposed to fit into.

Also, I recently got a brochure on Digital Linear Tapes, which use
conventional head technology.  They apparently store between 30 and 40
GB on a single tape, but the cost is high: wholesale prices are DM
3790 ($2500) for the 30 GB model (Quantum DLT2000XT), and DM 6690
($4500) for the 40GB model (DLT4000).  The tapes are comparatively
affordable: from DM 66 ($44) for a 20 GB tape to DM 175 ($115) for a
40 GB tape.

What's Linux?  Seriously, can you give me a pointer to the How-To
stuff?  Maybe we should think about copying?

What?  Why do you lack time?  Everybody else has plenty :-)

I'm wondering if there are any 'known' problems with using this
controller?  I just upgraded one of my servers to SCSI (from EIDE off the
motherboard).  I have the AHA 2940 UW SCSI controller and a Seagate Hawk
UltraSCSI drive.  Since the upgrade last thursday my server has rebooted
itself three times, without any sort of log or other message (I was not
around to read the console message as its stuffed in a machine room and no
errors were reported in any of the /var/logs).  Everything SEEMS to work
fine, the install went flawlessly and I have not noticed any other
problem--short of these reboots. 

Help?  I really can't have this server rebooting all of the time..

Thanks to those of you who are participating in this thread.

In my original post:
>I had an HP C1533A DDS-2 drive which worked fine, but which I exchanged
for a sony SDT-7000 DDS-2 because of the reliability warnings given in the
FreeBSD Handbook. Unfortunately my sony drive is broken - I/O errors on
read, can't format tapes using the Adaptec EZ-SCSI utility etc.  

In this email, I explain what my setup was for both the HP and Sony DDS
drives.  I RETURNED THE SONY TODAY because it was the last day I could do
so and get my money back.  I have not purchased a replacement yet as my
choice is dependent on the outcome of this thread :-)

I think there are a number of issues:

+ Is any one brand of DDS drive better or worse than another?
(or 'Do the HP drives warrant their Freebsd warnings?')
+ Can anything be done to extend DDS drive life?
+ Is there a common failure mode for DDS?

>From mail that I have received I am beginning to believe that the DDS

I don't know if HP drives are better or worse than any others.  That said,
I have been put off the Sony SDT-7000 as 1) my problems with the unit
supplied to me, 2) on the basis of replies, few seem to be in circulation
(are sony users at bleeding edge?) and 3) I can't see how the high
rotational speed of the SDT 7000 can do anything but degrade reliability
(cf HP).

Unfortunately I can't afford DLT, so DAT it is . .

Here are my setup details:

Hardware setup 1:
Adaptec 2940 (non ultra)
HP C1533A DDS-2 (internal, connected via adaptec internal cable).
The DAT drive is the only device on the SCSI chain.

Tapes which I used successfully on the C1533A:
+ HP DDS 60 metre.
+ Sony 90 metre computer grade DDS-2.

Dip switch settings:
+ Compression enabled at power on, with host control.
+ Media recognition active.
+ Caution on hard error.
+ Parity on.
+ Data phase disc.
+ Truncate request sense off.
+ Variable block size mode.
+ SCSI id 3

Hardware setup 2:

Unsuccesful Setup with sony SDT-7000 (connection as above).
+ SCSI id same as for HP DAT
+ DC disable (tried both ON and OFF) - what is this?
+ SCSI parity on. (both settings tried)
+ Termination on. (both settings tried)

The Sony package which I received had evidence that it had been opened (a
faulty return?).

Problems with the sony were:
- Excessive lacing and unlacing of the tape on boot up (it really seemed to
be making a meal of it).
- Inability to format Sony DDS-2 tape using the Adaptec EZ-SCSI utility:
  (read errors, tape removed from drive during format etc).
- device I/O errors when trying to read a tar archive created by the HP and
another DDS drive.

I don't understand this; you don't "format" DAT tapes.  The sony
units ignore the "erase" command because it makes no sense.

Are you sure you're conditioning your DATs correctly?  You will find
that a tape that's been in storage should retensioned (wind to end of
media, rewind), and must be at room temperature for best results.

Instructions on this sort of thing are included with most decent 
blank tapes.

We've been using and recommending to our customers the Sony SDT-5200
(DDS2, no compression) for over a year now, with no problems at all.
Several of these units are operating in arctic/antarctic conditions,
and there's one in a hut in Indonesia.  We receive tapes from all of
these sites on an occasional basis and, modulo conditioning shortcuts,
have never had any trouble reading them.

Sure.  That's valid for all tape drives.  The real question is, how
quickly?  The jury's still out on that one.

It can also improve performance.

I don't know if I agree with that.  Sure, it's built on the original
DAT technology, but that doesn't make it a consumer grade article.
Note that the estimated MTBF of the C1533A is 4 times that of the
35480A.  They're obviously doing something there.

To the best of my knowledge, there ain't no such beast.  The 90 metre
tapes are all DDS-1.  You need the much more expensive 120 metre tapes
to get DDS-2.  But at least you weren't using audio grade tapes.

Data compression.  Unless you're exchanging data with somebody who
doesn't have data compression, leave it on.

Ah, yes, this sounds familiar.  That's typically the way my 35480As
died.  Was this a brand new tape?  I've had cases where a tape written
on a bad drive can confuse a good drive.

I don't understand this.  DDS tapes don't need formatting.  What did
the documentation say on the subject?  EZ-SCSI is a DOS utility, and
you don't need it.  Or are you running this under DOS?  EZ-SCSI
supports all tape drives, some of which need formatting, and I
wouldn't put it past the program to run into trouble if you try to
format a drive that doesn't support formatting.

> - device I/O errors when trying to read a tar archive created by the HP and

It's always better to give the error messages rather than just a
statement like this.  What were the errors?  For example, my newly
repaired Exabyte still shows the same problems :-(

Dec 23 12:02:03 freebie /kernel: st1(aha0:5:0): MEDIUM ERROR info:10000 csi:0,0,0,13 asc:3,2 Excessive write errors

Looking at the first item on your list, however, I think I'd agree
that you do (did) have a defective drive.  You will probably not have
any problems with a replacement.

Quite correct.  90m tapes are DDS.  On the box it said compatible with
DDS-2, which is where my typo came from.  I am using 90m tapes as 1. I
don't have a need (yet) to store 4gb, 2. 120m tapes are thinner, 3. 120m
tapes cost four times as much.

My previous experience was using a Colorado Trakker 700 (and nobody dare
tell me that was a fast and reliable product :-).  The trakker did require
formatting, about 3-6 hours of it, to be precise.  My Adaptec 2940 card
comes with Adaptec Backup on the EZ-SCSI disc.  When using this utility
under Windows 95, I formatted DDS tapes before initiating a backup.  I
would guess that this 'formatting' action would merely write an empty
volume catalog to the tape (containing the name of the tape etc.) which
would mean something to the Adaptec Backup application itself (hence this
operation only took 90 seconds) and might include retensioning.

With the HP C1533A, there were no errors when formatting (writing directory
info) to the tape.
With the Sony SDT7000, it gave errors gallore.

Hmm.  Where did these diagnostics get output?  I executed tar from the
console and was told 'device I/O error', _NOTHING_ more than that!
Unfortunately I can't try it again, since I no longer have the drive ;-)
Is there a kernel config option for specifying the level of diagnostics?

You're probably right.  However, my faith in the Sony (which incidentally
was shipped without any installation instructions) has been dented.

The tapes I have used were at 21C, normal pressure and humidity.
I did not retension the tape (unless this was done as part of the Adaptec
Backup 'format' action), but I had used them successfully on the HP C1533,
no problems.  I will retension new tapes in future.  No instructions were
provided with HP or Sony DDS cartridges.

I doubt whether my problems were to do with conditioning, I am sure that my
SDT-7000 was faulty.

Do you have any experience of the SDT-7000?  The SDT-7000 has a drum
rotational speed twice that of the SDT-5200 (as Greg noted, to enhance
performance).  Running a drive at a higher speed can only make it more
susceptible to mechanical failure.  I would guess that the 5200 has been
out for longer and that any bugs/problems would be more likely to be
observed/sorted out than any with the 7000.  The small price difference
between the two models make me think that there has been little change in
the funamental mechanism design and that 8000rpm may be too fast to
transport the tape using the existing mechanism.

Regards,

Simon

PS I hope Greg has more success with his exabyte drive.

I REALLY need help with this, our server is continually rebooting since we
installed the AHA 2940UW controller and new UltraSCSI drive.  It is not a
heavilly loaded system, but it does run a database system that NEEDS to
syncronize its database before shutting down.  Every time this system
reboots we loose critical data to the last backup.  This is flat out
unacceptable.  I really like FreeBSD much more than Linux, but at this
point others in the group are suggesting we move to Linux because they
know this hardware works fine in Linux.  In my experience I've never known
a system to simply reboot when it was a hardware problem (generally if its
a hardware problem it simply freezes up or does not work at all).  This is
working for two to three days when suddenly *wham* reboot.

Help??

Have a look at ahc(4), /usr/src/sys/pci/aic7870.c, etc.  There are serveral
options to play with.

The 2940's got lots of knobs in the <ctrl-a> bootup menu too, one is
to disable ultra, maybe that'll do it...  ahc(4) warns
about some drives (Quantum?) not working properly if the speed is set
to wide open.

I just got a QuickTech motherboard with on-board aic7860; it's not quite
as good as the stand alone version, but it seems ok.  I haven't done
a `make world' yet, but several kernel compiles.

What version of FBSD are you running?  I've got problems using 2.1.5 with
a Quantum ultra scsi driver on the ncr driver... it won't even boot.  But
-current/2.2 works fine.  It's not a problem because we're going to use
2.2 anyway...

FreeBSD 2.1.6. The controller is AHA 2940UW and the drive I have on it is
a Seagate Hawk UltraSCSI 1.05 GB (ST30155N).

I'll peek at the various options..

Lots of things, I would imagine.  For example, making the drums out of
something more durable.  Stefan said (in private mail) that Sony have
a special technology for the 7000, he thinks something like an air
cushion under the tape.

I'll go for (1) and (3).  I haven't seen any problems with the
thickness of 120m tapes.  I use both in the C1533A (and in the Archive
changer that I have just bought).

DDS tapes don't have a volume catalogue.  I suppose the Adaptec backup
might use it anyway, which IMO is another reason not to use it.  It
really destroys interchangability.

It would be nice to know the messages, but considering it could hardly
load the tape, I suspect that they wouldn't say too much.

They should have appeared on the console.  They're output by the
system to syslogd, and syslogd writes them whereever you tell it.
Check /var/log/messages, whence I extracted these messages.

Don't be too sure that that wasn't your retailer.  They frequently
sell things in two forms: with tape, software, cables and lots of
packing, or just the naked drive.  I have had problems with Sony for
the way they have to do things differently (like putting the SCSI
connector in the wrong way round, so you have to twist the cable to
fit), and I thought the drive itself could have more written on it,
but to my recollection the drive I was given had instructions.

Mike wrote this before you mentioned the load problems.  I think they
put the whole thing into a very different perspective.

> No instructions were provided with HP or Sony DDS cartridges.

I just opened a brand new HP DDS-2 cartridge (120m).  On the back of
the label foil there are pictures suggesting that you should tape a
red cross to the cartridge and then attack it with a horseshoe, that
you should wobble the read-protect tab backwards and fowards while
inserting, and that you should lay a thermometer on the cartridge.
Could be I'm misinterpreting this, but there is no text to go with it.

In addition, they write:

* Cleaning your DDC drive with HP's DDS Cleaning Cartridges is
  important to maintaing the performance of your drive.

* Recommended cleaning frequency: (rather silly table)

Another 4 points about cleaning the drive.  Nothing about
retensioning.  One point to you.

I honestly don't think so.  The C1533A rotates at 5400 rpm,
significantly faster than the 35480A, and despite that it's more
reliable.  Remember that they're learning things about the drives as
they build them.  HP's suggested MTBF of 200,000 hours for the C1533A
vs. 50,000 for the 35480A suggests that that's the case.  From what
I've heard, I would think that the SDT-7000 might just be the best
DDS-2 drive available, and that you've just been given a dud.  I
wouldn't let that experience shake your confidence completely: I'd go
back to the dealer and say, "OK, that device may have been a dud.
Give me another, in original packing, and I'll try it again".

> PS I hope Greg has more success with his exabyte drive.

So do I :-) But I fear the guys who repaired it fixed the wrong
problem.  They assumed a drum failure, though what I've heard through
other channels (the Exabyte specialist at Siemens-Nixdorf), drum
failures are relatively uncommon.  In case anybody out there
recognizes the problem:

  When I start a backup, everything runs fine.  By observation, the
  drive writes without any backing up (i.e. backtracking and
  re-reading or writing).  After about 30 to 50 minutes, it starts
  backing up, and shortly after that it can't recover the data even
  after 20 backups, and the backup aborts.  I've tried several tapes,
  including brand new ones, and of course I have cleaned the drive
  with an original Exabyte cleaning cartridge.

There is next to no chance that someone will find and fix your problem
during the xmas holidays.  Just zilch.  Justin is off at Christmas
with his folks, I don't know anything about the SCSI subsystem, anyone
with any kind of life at all (and I do not count myself) is off DOING
something right now and will be until the 2nd of January or so.  That's
life during the holidays.

It would therefore make a lot more sense for you to either find a more
promising version of FreeBSD on this system (and I don't know if
upgrading/downgrading will affect your symptoms, but it's certainly
worth a try) or, indeed, just migrate it to Linux.  If that solution
works then it works, and that's the bottom line.

I have just acquired a HP T4000s tape drive for my primary FreeBSD
machine, which is a mail/news/file/print server for my home net.

However, it doesn't want to do anything useful :-( (commands & results 
below).

The drive is connected to the SCSI bus between the HD & CD-ROM, and 
the terminating resistors were removed.  I am not aware of any other 
system "funnies" which might be attributable to poor SCSI cabling or 
bad termination.

I notice from the boot probe (see below) that the drive appears to 
have v1.05 firmware, compared to another recent posting to the list 
having v1.06.

The system is stock 2.1.0 installed from CD-ROM.  I have the 2.1.5 CD-ROM
(have held off installing on this system until I could back it up
adequately), and plan on snarfing a 2.1.6 CD-ROM as soon as they become
available here.

Any thoughts/advice appreciated & compliments of the season to all.

What follows are the results of my attempts to use the drive + the system
config & boot transcript.  All commands issued as root.

An "mt status" results in:

---8<---8<---8<---
Present Mode:   Density = 0x45         Blocksize = 512 bytes

I recently had "system crash and reboot with hardware SCSI problems."

I read the followups and didn't see any mention of what MB is being used. 
Recently I couldn't pass up an opportunity to buy a PCI MB w/ AMD 5x86/133 
for $99. Paid $17 more for 256k extra cache. This was to upgrade my 486DX33 
FreeBSD system at work. Took this machine (the one I'm on now) down to 48M 
from 80M and pulled my 2nd 2940 out, and put it on the new MB. (Hint: you 
are supposed to be laughing, I am, $200 of memory and a $150 controller, 
another $250 of SCSI drives, on a $116 MB/CPU). Anyhow, FreeBSD 2.1.5 
crashed under heavy SCSI usage. Upgraded to 2.2-current, then 3.0-current, 
upgraded Adaptec BIOS from 1.10 to 1.16. No change. Compared GENERIC 
against my config file and tried all the AHC options. Crash usually said 
something like, "Panic: Page Missing".

Finally figured out the cache on the MB was the single cause of my crashes. 
Later found a reference that knew everything there was to know about this 
cheapie MB: <http://users.aol.com/sdnd/vip.htm>. Thought I'd tried both WB 
and WT cache modes, but after reading the above page I got brave (or 
bored), put the cache back in, tried WT cahce mode, and its been running a 
month or so w/o any SCSI problems.

Interesting thing about this problem was iozone couldn't make the system 
fail, "make world" with the source/obj on a SCSI drive was one of the best 
ways to crash (boot disk and running system are IDE). Another way to crash 
was to put a swap partition on a SCSI disk, but this was too good of a way 
to crash the system.

My problem was hardware.

This is interesting.  Your NCR doesn't seem to appreciate the tape.  You
might verify that your cable is okay and termination correct.  Remember,
termination at the ends of the chain only.  The NCR will terminate itself
properly; make sure the last thing in the chain is terminated and that
nothing else is.

Linux uses a ported version of FreeBSD's aic7xxx driver.  If the driver is
really the culpret I would expect the results to be much the same
regardless of which OS you use.

I am the author of the driver, but I cannot help you unless I know what the
console messages are and what the panic message is.  Please install a
serial console to a stable machine with a scroll back buffer so that you
can capture what happens before the machine reboots.

Even if you do get me this information, I cannot promise immediate action
on this problem.  I can't do anything about it until at least the 1st. of
the new year and even then I will be extremely busy.  I can, however,
promise that all of my free time will be devoted to aic7xxx driver issues
until your and others problems are solved.

a local hardware vendor has suggested to stay away from the AMD K-5 for linux; 
he says he has had a lot of problems.   does anyone know this to be a valid
suggestion for freebsd as well?

has anyone had any experience running freebsd on IBM Aptiva's A90 or A92?  
these are discontinued boxes, but available on the refirb market (intel cpu's.)

thanks,

We're using the K5-PR100's with no problem at all; very cost-effective
against the P120 (the only other low-end Pentium-class CPU you can get
around here just now).

My experience in tracking down ``spontainious reboots'' on FreeBSD systems
is that this is usually either memory or a bad motherboard.  If I recall
your earlier mail you had converted from IDE to AHA2940, which leads me to
suspect a motherboard problem in the cache invalidation logic with 
respect to bus mastered DMA.  

You didn't saymuch else about the hardware, and ``it'll run Linux'' doesn't
tell me much, as Linux does not do a lot of the performance enhancements
in FreeBSD that requires _CORRECTLY_ designed boards.

Hardware problems _often_ cause exactly what you are seeing, but then so
do software problems.
