I had the core dump problem with chg-scsi as well. I am on NetBSD/i386
V2.0.2. I did a couple of things, of the two I am not sure if both were
required but:
I am running a HP SureStore DAT24x6 changer.
The first was:
I set my changerident to: "C1553A". (The closest value defined in chg-scsi
to my changer/drive).
I see "FastStor DLT" is defined. Have you tried that in your chg-scsi.conf ?
I looked through changer-src\sense.c and I see the following special entries
for changers.
ADIC DAT AutoChanger
L500 ATL
HP 1553A
HP 1537A
Tandberg TDS 1420
DLT8000
DLT7000
AIT VLS DLT Library
AIT VLS SDX Library
Exabyte 85058
Exabyte 10e Library
Exabyte 210 Library
Exabyte 230D Library
Spectra Treefrog Library
It would appear that the sense.c structure is defining inquiry results and
defining how to interpret them.
Your changer may require some entries in there.
Here is the chg-scsi.conf that I use that works for me on my HP changer. My
changer device on NetBSD
is "/dev/ch0". "dev /dev/nrst0" is my no-rewind tape drive device,
"scsitapedev /dev/rst0" I added
so that my "tapestatus /usr/pkg/etc/amanda/st0-status" file gets update with
error status values
after a run. My changer did not seem to require the "eject" value to be set
so I left it at 0.
"scsitapedev" may also be key as I think it changes how it talks to the
drive/changer.
With "debug 9:0" I get lots of detail in chg-scsi* files I find in
/tmp/amanda.
number_configs 1
eject 0 # Tapedrives need an eject command
sleep 5 # Seconds to wait until the tape gets ready
cleanmax 50 # How many times could a cleaning tape get used
changerident C1553A
changerdev /dev/ch0
debug 9:0
#
# Next comes the data for drive 0
#
config 0
drivenum 0
dev /dev/nrst0 # the device that is used for the tapedrive 0
scsitapedev /dev/rst0
startuse 0 # The slots associated with the drive 0
enduse 4 #
statfile /usr/pkg/etc/amanda/st0-slot # The file where the actual slot
is
stored
cleancart 5 # the slot where the cleaningcartridge for drive 0 is
located
cleanfile /usr/pkg/etc/amanda/st0-clean # The file where the cleanings are
recorded
usagecount /usr/pkg/etc/amanda/totaltime
tapestatus /usr/pkg/etc/amanda/st0-status
# This is the end
There is a command documented as: "chg-scsi -genconf". What does that do in
your case ? I have never tried it
on my machine.
Can you make some of those available after performing some of the commands
that work and ones that don't ?
Under chgscsi.txt in the docs directory of 2.4.5 there are lots of notes on
chg-scsi.

Subject: Questions re: the chg-scsi documentation
I was going through those pages a bit this morning and
had a few questions..;
Firstly, at the Configuration Notes it says I should
be able to get the changer value with modprobe sg.
That command returns nothing; which doesn't seem
right? But if I do a modprobe sg -l then I get:
/lib/modules/2.6.8-24-default/kernel/drivers/scsi/sg.ko
So have I got the right module loaded for sg devices?
Secondly, what does -status do? what is the param you
have to pass it?
Thirdly, around the changerident section, it lists
Faststor DLT which is what I run. It's listed as an
"other value". Does that mean chg-scsi supports my
drive w/o the changerident argument? Whenever I try to
add it, chg-scsi just gets cross at me.
Thanks for any help. I'm getting so close to this tape
drive working that I'm almost sick; chg-scsi will now
pick a tape and load it! :} But it still segfaults on
-scan, and it will "eject" the tape but doesn't know
how to unload it (I have to follow up with mtx -f
/dev/sg1 unload)
Good weekend to everyone..!
