Subject: DRM 5004x Jukebox Error Codes
There was a blown fuse (1.5A/125V H107-H108). This has temporarily been
replaced with a 1A/250V fuse from CRF.
When performing the "Aging Mode Test" (pages 3-17 to 3-23 of User's
Guide), the disc transporter rises to the top of the jukebox, the LED
display cycles various digits, and stops at 0F-000 with a flashing red
light--with the door either open or closed. The following is the recorded
error history:

With help from Johnathon, Ian from CRF, and Bill Paul we were able to hook
up the jukebox to Yemini's linux box using an 8 inch SCSI cable. After
recompiling the kernel, we managed to mount and read (simultaneously)
under LINUX four CD-ROMS in the four drives. Later, we were were able to
play an audio CD. So, it appears that the jukebox works.
The only difficulties now are:
1) the commands to load and unload CDs are currently being manually
executed using test mode 4. Software would be the next step.
2) we need a 50 pin centronics to 68 pin ultra SCSI cable which is less
than 3 feet long. It looks like the existing SCSI cable could be used
with either the NT or Sun Ultra, but it's too long which apparently causes
SCSI problems.
Obtaining a cable is the main problem at the moment.

I tried the existing cable with the NT machine again and was able to read
a few CDs. It would still be convenient to get another scsi cable for the
Sun Ultra, though. I downloaded and installed the !XOS Jukeman NT software
with a 30 day license (10/17). I haven't yet figured out how to use it.

Indeed. Have you checked http://sunexpress.usec.sun.com/sunplaza/ to see
if they have a suitable cable?

Let me know if you have difficulties. I'm forwarding you a message in
that regard. I haven't discussed pricing with them, but we may be able
to use this.

Dear Mr. Schulzrinne:
Thanks for contacting us regarding the challenges you are having with
your jukebox. Please call me at 714-766-1900 (Southern California)
either today (Monday) or tomorrow. I will be out of town this Wednesday
all day long. I will see what I can do to assist you.
If you would like to speak with our technical support department
directly, please call 650-294-5827.
We continue to do user profiles in various segments of the market. We
are interested in getting a success story in the education area. We
would be able to offer you a significant discount if you were willing to
discuss your application with us and how a CD jukebox with IXOS JUKEMAN
was able to solve a need that you had. I would like to discuss this
with you as well when you phone.
First things first however. Let's get you up and running and satisfied
before we ask for a success story.

Subject: FreeBSD and the jukebox
Ion mentioned that he thought it would be a bad idea to try using the SCSI
changer on the UltraSparc, since Sun SCSI hardware is apparently very
finicky. Since we presumably don't want to actually do primary development
on NT, though (or at least I certainly don't) I considered installing
FreeBSD on one of those machines, and so I decided to look and see what kind
of support FreeBSD has for them.
Much to my surprise I discovered that FreeBSD seems to already have a SCSI
Changer device driver! It's commented that "it hasn't been tested in a
while" and the person who wrote it seems to have fallen off the net, but
it seems to me this would obviously be a *much* better starting place for
getting our own support working than trying to write something from scratch.
I also found (in the FreeBSD mailing list archives) a kernel patch to
support reading the data from audio CDs into the computer -- it's against an
older version of the kernel but it looks like it should still go in cleanly.
Now, the main problem here of course is that if we wanted to use the changer
from a FreeBSD box we'd have to install FreeBSD on one of the
Microsoft-donated Gateway Pentium Pros -- the Dells don't have SCSI cards.
This is, of course, a political issue, so I thought I'd run it by you
(Henning) to see what your opinion was on this...
If you (Raj? or anyone) want to look at the sources for the changer device,
they're in the FreeBSD kernel source tree on irt or bmt in the files
/sys/scsi/ch.c, /sys/scsi/scsi_changer.h, and /sys/sys/chio.h. The patches
to support CD-DA are in ~lennox/Ftp/cd-da/ on any CS machine.

Jonathan,
The ultra is now talking to the CD Jukebox and sees 4 CD readers
and a Media changer.
I've compiled some basic SCSI commands, and will make up a suite
of media changer commands sometime this week. However I need
some sort of local root access on ind to test these commands.
Is there a local root account that you use?
-Raj
P.S. There are "inquiry", and "mode-sense" commands in ~kumar/bin.

We might keep in mind that if there are problems with the current
configuration on ind.cs (kernel patch, etc), we still have the IXOS
software option to fall back on. The jukebox worked fine (data only) as a
shared drive from remote NT machines when I had it hooked up to njt.cs.
There is also a Solaris version which implements caching and a database
and supports NFS--there's even a limited (free) demo version. This
software is relatively easy to install (but requires root access). I'd be
very happy to install it on ind....
