I'm sorry this summary is so late. Here's the original
question:
| I have attached a Pinnacle Micro REO-6500 optical
| jukebox to an IPC. The problem is that I keep on
| getting the following kinds of errors:
| -------------------------
| Oct 15 22:41:06 ixcim6 vmunix: sd0a: Error for command 'write'
| Oct 15 22:41:06 ixcim6 vmunix: sd0a: Error Level: Retryable
| Oct 15 22:41:06 ixcim6 vmunix: sd0a: Block 10528, Absolute Block: 10528
| Oct 15 22:41:06 ixcim6 vmunix: sd0a: Sense Key: Aborted Command
| Oct 15 22:41:06 ixcim6 vmunix: sd0a: Vendor 'MAXTOR' error code: 0x47
| -------------------------
| Oct 15 12:56:10 ixcim6 vmunix: esp0: Target 3 didn't disconnect after sending COMMAND COMPLETE
| Oct 15 12:56:10 ixcim6 vmunix: sd0: SCSI transport failed: reason 'tran_err': retrying command
| Oct 15 12:56:10 ixcim6 vmunix: jb0: SCSI transport failed: reason 'reset'
| -------------------------
|
| Any ideas as to what may be causing this and how I might
| fix it would be greatly appreciated.
The answer probably won't help anyone unless they have one of
these jukeboxes. Firmware level 7.114 has problems unloading
a disk. I received new firmware which fixed the problem and
all the errors stopped.
Here are the answers I did receive, in case they might help
someone else:

My guess based on the scenario is that you have a MAXTOR 8760 disk drive
since we have similar problems with them. If this guess is correct
1) get the latest Sun specific version of the firmware from Maxtor
2) use as short a cable as you can get
3) use an active terminator versus a passive one

Hi Bill,
Looks like a bad cable, bad connection, or bad scsi termination to me.
Even if there is other stuff on this scsi bus which is working fine you
can still have a bad cable or connection. I find that the small scsi
connectors on the suns are notorious for bad connections. Make sure
that it is not hanging down where it plugs in as this can cause a bad
connection on the top row of pins. If necessary prop it up a bit.
regards,

Caveat Emptor: We had one of these buggers, and returned it to
Pinnacle for three REO-650's, which don't work well either. The unit
got flakier and flakier; it seems the device drivers are not well
written.
Your actual best bet may be to get a few of the 650 drives like we
did, if they will fit what you need. We found that we were spending
upwards of 15 hours a week making the jukebox work, rebooting the
machine it was attatched to, etc. Its easier to spend our time
mounting and unmounting platters. (Of course, we do that via sudo
now...)
I'd examine closely the justification for using a jukebox, the unit
seemed to be about as robust as a snowball in hell.

Try swapping out your terminator.

Uhmm, I have the same problem with a Seagate WREN IX. My config is
a secondary sbus SCSI card on a 670MP and on the bus is a Fujitsu 1.3G
external disk, the Seagate WREN IX 2.0G external disk (both in the same
external cabinet) and an Exabyte 8mm tape drive. My errors are as follows:
Oct 20 23:08:02 casper vmunix: sd6h: Error for command 'write'
Oct 20 23:08:02 casper vmunix: sd6h: Error Level: Retryable
Oct 20 23:08:02 casper vmunix: sd6h: Block 531872, Absolute Block: 1541312
Oct 20 23:08:02 casper vmunix: sd6h: Sense Key: Aborted Command
Oct 20 23:08:02 casper vmunix: sd6h: Vendor 'SEAGATE' error code: 0x47
Oct 20 23:19:31 casper vmunix: sd6h: Error for command 'write(10)'
Oct 20 23:19:31 casper vmunix: sd6h: Error Level: Retryable
Oct 20 23:19:31 casper vmunix: sd6h: Block 1317184, Absolute Block: 2326624
Oct 20 23:19:31 casper vmunix: sd6h: Sense Key: Aborted Command
Look familiar? Recently I talked to a friend of mine who suggested looking
at the SCSI terminators so just today, I ripped open both the disk cabinet
and the tape drive. Seems the Seagate had internal terminator AND the
tape drive had internal terminator. I removed both and put an external
terminator on (I like to *SEE* the terminator - that way I know it is
there :-). So far all seems ok so this could be your problem as well -
double SCSI termination. It is worth a look.
Also, I would be interested in any responces you get from the mailing
list (even though I am pretty certain this is the problem).
