Thanks to all who helped me with this. The problem is still not
100% solved. I could only manage to reduce the frequency from 20 or more times
a day to 1 or 2. Most of the answers pointed to the /etc/system file. I
should set scsi_options=0x58. One of the answers suggested to call Micropolis,
and I did. They told me to install patch # 101228. I did and didn't help
much. I remember reading a while ago on the net that the proper scsi_options
should be 0x78, so I tried it. And it seems that this with the patch reduced
the frequency of timeouts. Some people also told me to check the scsi
terminations, and as far as I can tell they are correct. I can't check the
SUN hard disk because SUN does not ship a manual with the hard drive.
I am almost believing John DiMarco (firstname.lastname@example.org), who
said that they had this problem and it was only solved with the replacement
of the motherboard. I'll call SUN tomorrow...
For people that asked to send a copy of the solution, my advice is:
apply the patch and use first scsi_options=0x58, and if doesn't work, use
After all, does anyone know exactly what these numbers for
the scsi_options mean? Is there a table of meanings??? Does anyone have
a list of variables that can be set on /etc/system and their meaning and
Thanks to everyone who helped!!!
