NBU 3.1.5 on NT4
STK9714 with 6 DLT7000
Master with 3 DLT7000 and robot arm
3 slaves, each with 1 drive in the STK9714


I have 2 problems:

1.  My cleaning tapes are getting stuck far more than usual, this seems to
be when they use their last clean (20).
Anyone experienced this?
I have autocleaning on for every 25hrs of drive usage, I was advised to use
this figure, but I'm thinking it's too much.
I've disabled autocleaning for now and chucked this batch of Maxell
cleaners.


2.  When a tape gets stuck, the drive goes down, so my Operators try and
remove the stuck tape manually while other backups are running to the other
drives/slaves.   Last night I had multiple stuck tapes and drives down, can
this be caused by the robot door being open so the robot is "offline"?
(Door was open for quite a long time - during which another drive might have
needed a tape swap)
If this is the case, how can you remove a stuck tape when other drives are
in use?


thanks
Bob
