I have several Sun Ultra 45s (Solaris 10) giving me the same errors
when it comes to reading optical media:

ATAPI drv, target: 0, reset failed but continuing
timeout: reset bus chno = 0 targ = 0
Changing the mode of targ:0 to Multiword DMA mode:2
Drive not ready before set_features
timeout: reset target chno =0 targ = 0

It doesn't occur right away, but when it does occur, it requirs a
reboot to clear up. Once the error occurs ti won't read any more
media.

Physical connections are intact and the system is up to the latest
patches.

Does anyone have an idea what's up here?

Thanks

Have you update the OpenBoot Prom? The current patch is 142703-01
(OBP 4.30.4)

I have 40 of these in production and I've not seen this. I use to
have many USB issues before updates.

The last time I needed to do this, I downloaded the update, stored it in
/1452703-01, and then booted the system telling it to boot from
/1452703-01. The system booted the file, updated the PROM, etc.

ISTR that there is a jumper on the main board that must be set to allow
the PROM update.

There is Sun documentation on how to do this. See "Sun Flash PROM Guide
for Workstations and Workgroup Servers -- Standalone Version". The Sun
part number for the current version is 802-3233-27. If this manual does
not apply to your system, find a manual that does!

Be careful! If you screw up you can "brick" your system and will have
to pay Sun to bail you out. I have done this three times without
problems on three Ultra-10 Workstations. You should be sure that your
system is protected by an Uninterruptible Power System (UPS) because a
power failure during the update can also "brick" your system.

I wouldn't have thought this was a USB problem, but I do have USB
issues that appear unrelated to this. This particular problem affects
the internal CD/DVD reader. I can find nothing at SunSolve about this
as relates to Solaris 10 and ATAPI, but the problem does seem to exist
for Solaris 8. I can't find any patch correlation between 8 and 10
for this problem.

However, I'll update hte OBP and see what happens.

Ok, the OBP has been updated to the latest version (4.30.x). I'm
going to aproach this from a USB point of view.

USB devices now register with the O/S, according to entries in /var/
log/syslog, but they don't mount to a file system beyond the first or
second time they're plugged in. After a reboot, USB devices will
register and mount, leaving an icon on the desktop. Beyond the first
or second time per boot, they'll only show up in rmformat. What might
be keeping them from fully mounting?

If I can solve this problem, I'm guessing my DVD reader problem will
also solve since it shows up as a removable device, even though it's
mounted internally.

Thanks
