Very Computer

I have recently aquired an old Adaptec AHA1542b ISA SCSI card and a Sony
SDT-5000 DDS2 DAT drive and am having problems. The SCSI card is the only
SCSI card in my system (a P166 with 64Mb RAM running SuSE 6.3) and the
DAT drive the only SCSI device.

When I try to write to a tape say using a command such as

find /home -print | cpio -ocva > /dev/st0

It writes about 20 Mb then stops with a change media message. Unusual for
a drive with a minium of 4GB capacity. It also seems to be writing very
slowly. After the failure occurs I can no longer do anything with
/dev/st0 without removing the aha1542 module and reloading it as I get
"device not configured" errors.

When it fails the console log contains one of the following messages:

Sent BUS RESET to scsi host 0
st0: Error with sense data: [valid=0] Info fld=0x0, Current st09:00:
sense key Not Ready

or

Sent BUS RESET to scsi host 0
Additional sense indicates Power on, reset, or bus device reset occurred
Additional sense indicates Logical unit is in process of becoming ready

I am running the SCSI adapter as a module. It seems to load OK if i
insmod aha1542. It also recognises the DAT drive. When the SCSI module is
loaded it generates the following messages:

Configuring Adaptec (SCSI-ID 7) at IO:330, IRQ 11, DMA priority 5
scsi : 1 host.
Type:   Sequential-Access                  ANSI SCSI revision: 02
Detected scsi tape st0 at scsi0, channel 0, id 6, lun 0

Which all looks OK to me.

running mt -f /dev/st0 status generates

drive type = Generic SCSI-2 tape
drive status = 318767616
sense key error = 0
residue count = 0
file number = -1
block number = -1
Tape block size 512 bytes. Density code 0x13 (DDS (61000 bpi)).
Soft error count since last status=0
General status bits on (1010000):
 ONLINE IM_REP_EN

The 1542b SCSI card jumpers are set to:

Sync negotiation: disabled (factory default)
SCSI Parity Bit: enabled
SCSI address: 7
DMA Channel: 5
Interrupt Channel: 11
DMA Transfer Speed: 8.0
BIOS: disabled
I/O Port Address: 0x330
BIOS Wait State: 0
BIOS Address: DC00
Floppy Support: disabled
DMA Request Channel: 5
DMA Acknowledge Channel: 5
IRQ Channel: 11

The DAT Drive is jumpered as follows:

SCSI ID: 6
Data compression: enabled
SCSI Parity: On
Terminator on: On
Terminator Power: On (I have also tried with this set to off as well)

Oh, I forgot to mention, the drive is connected internally inside my PC.

Any help would be much appreciated. I'm beginning to think the drive
doesn't like the old Adaptec card. I'd prefer not to have to go and buy a
new card if at all possible as I only really want to run this single tape
drive.

Cheers,

Sean.

does it work when it is compiled not as module ?

at www.adaptec.com there are some installtion tips
and a well done FAQ.
one hint is to modify the bus timing in case of probs.

does it work with 5.0 ????

I am beginning to think this card is trouble.  I ran one for 6 months,
no problem, then suddenly it decided to start locking the bus, and
thence the whole machine, requireing a hard reset and reboot to fix.

I gave up, and threw some more money at it, getting an Advansys card
which seems to be a lot more intelligent, and hasn't crashed me since.

In my case it would write maybe 11 megs to the tape, at a good rate,
then lock the scsi bus up tight.  Diddling terms didn't seem to effect
it one way or the other.

I've tried it compiled into the kernel (i.e. not module) with the same
results. I've also tried different combinations of i/o address, dma
channel, and interrupt. I've a feeling it's just a *card.

Cheers,

Sean.

Gene,

Which Advansys card did you get ? I am thinking of getting the ABP3925
which is fairly cheap. I only want it for the tape drive, and possibly a
CD-RW at a later date.

Cheers,

Sean.

An ABP-930, which is a 'SCSI-2 ULTRA', has the old style 50 pin hidens
on the back, and a 50 pin ribbon for the internals.  This thing is
supposed to be able to move 20 megs/second, but my old drives would
probably upchuck the whole lunch if they tried that.  These cards are
actually a risc based interface, doing a lot of stuff the drivers don't
have to worry about.  When I moved the hard drive to it so I could
remove the old adaptec card, the connector that I plugged into the drive
turned out not to be polarized, and I obeyed Murphy's Law and plugged it
in bass-ackwards.  Very shortly after the memory test in post, I was
looking at a message from the card advising me the termination was
munged, would I be so kind as to double check it please?

I think I'm gonna like this card.  (-:

Cheers, Gene

I used to have a SDT-1000(? I think- it was years ago) and a 1542B, and
that combination was *very* senstive to cabling issues. Ensure that, first.
