I've been searching the web, looking in archives, but no juju.  We had
the Quantum Guy out here and he fixed our 2 dlt8000 drives with
swallowed tape leaders.  Did a visual inspection, found no problems with
the L1000 library, overall.  But, he did witness the problem we're
having when using Networker to control the tape transport to and from
the slots and drives.  

He believes that Networker isn't waiting long enough for the tape to 
rewind before it's ready to be moved.

My question to you all:  Have you had to tweak the "Eject sleep" and
"Unload sleep" parameters?  If so, what values work for you?  I've seen
anecdotal stories of tweaking these values, but no examples about how
long.  

The Quantum Guy called his techie who recommended 120sec for "Unload
sleep"!  The default is set to 5 sec, so 120 sec seems to be a bit
unreasonable.  I mean, if I'm labeling 30 tapes, it's going to take 2+
hours.  My DLT7000s never exhibited this problem.

I've looked at Legato's knowledge base, but nothing useful comes up.

I'm still reading my performance tuning doc... but could use some
feedback from the list.

Thanks,

deb
