Not.  Should take about 5 minutes, including load and unload.

I have just struggled through a full week with our L1000 and 4
dlt8000's.  Some folks here have said they had to extend various
timeouts in order for things to work properly.  

Before I discovered the *real* problem, I tried this.  It seemed
to work better, but I was fooling myself.  Labeling tapes took a long
long time, and sometimes failed completely.

What I found was a bad/flakey SCSI terminator.  Once I replaced the
offending hardware, I reset all the timeouts to the defaults, and
everything works great.  Labeling barcoded tapes takes less than five
minutes per tape.  

Have you looked for read/write errors in /nsr/logs/daemon.log or
messages?  You might inspect your hardware configuration.

Good Luck,

deb
