are the high density device ids (i.e. 5GB).

Thank to...

Summary of original question:
> We are running dump backups to an Exabyte EXB-8500 8mm Tape drive.
> Two machines are backed up, one is running SUN OS 4.1.3 (Exabyte is
> local on this one) and the other is running Solaris 2.3 (w/maintenance
> supplement 1).
> The problem is that the backup fails after about 2.3 gig saying it's at end
> of tape. Any ideas on the cause? Below is the script that runs and
> the log file showing the output:
> /etc/dump 0udsbf 54000 13000 126 /dev/nrst1 /sw2 >>& /tmp/dumplog$$
>> script and log files deleted...
