I think I have a problem with the timing on my SCSI controller for a Sun 
Sparcstation LX running Solaris 2.4.

I have and extenal SCSI disk that works fine except when I try to backup the 
disk to a tape drive (Tape drive works fine when disk in question not 
attached, Disk "causes" same problem on similar system with same type of tape 
drive).

It appears that this is a problem with timing on the SCSI chain.  I have heard 
that the SCSI transfer rate can be reduced slightly using an entry in a system 
file, and that this change should make all drives on the chain happy.

Does any one know how to do this ?


Thanks and Regards,
