My orginal question:
> I moved my ADIC VLS 4mm tape drive (it is a tape autochanger with dual
> Sony 4mm tape drives) from my SunOS system (Sparc1+) to a Solaris system
> (w/ Ultra 1), and I used tar command without success:
> # tar xvf /dev/rmt/0n
> tar: tape read error
> (the font panel of the tape drive did give me a signal indicating that
> the system is trying to access it)
> And the msg on the console:

Thanks for Mark Steph, Ada Chan, Joel Lee, swee-chuan khoo, and Stefan to
reply my question. I do have scsi terminator and no scsi target id conflict.
The final solution is I cannot use the /dev/rmt/1 driver, instead, I need to
use the driver as well as the backup software Quick Restore from Workstation
Solution company (tape backup software vendor). I loaded the software from
a Sun tape drive of the other system, and ftp the tar file I made to this
Ultra 1 system.
