NW 6.1.1 for W2K on Proliant DL580

Two Problems:
Our Exabyte690d autoloader has a problem where it tries to load a tape into
our DLT7000 drive and the drive light goes dirty.  Legato usually unloads
the tape, then loads the cleaning cartridge before it tries to use the drive
again.  This happens multiple times per night.  We go through a cleaning
cartridge every couple of days. We have several hundred DLT-IV cartridges
that Legato can't seem to handle, but when we take them to a standalone DLT7
or 8000, they work just fine,  on load the drive light goes dirty, but then
clears itself.    This happens when trying to label, or when a group calls
for a mount.  We've replaced the exabyte, we've replaced the SCSI cables,
but it appears that it's the way that Legato handles the load process -
something is definitely different in 6.x from 5.x, or something is different
in NT 2K from NT 4.0.  We have d/l'ed MS hotfixes for the DLT handling, but
this did not help.  We have tried various DLT drivers, but we are stuck.
Please help.


Problem #2:
Occasionally, Legato tries to unload, it starts issueing:
\\.\Tapex Requires cleaning

messages at the rate of 2-5 per second

The drive tries to unload, but is not successful, therefore the messages
just keep pooring out by the boatload.  This loop goes on until we manually
eject, or the SAVEGROUP is stopped.

Has anyone else experienced this problem ?   This started when we upgraded
from NT 4.0, Legato 5.5.1 to Win2K and Legato 6.1.1.
