Veritas will kick the tape out when needed- dont have your operators =
open the door and break the leader, the tapes sometimes stay there =
until a drive is needed, all your past breakage is operator error, 4000 =
mounts maybe or bad drives but leaders dont just break, it comes from =
someone trying to open the door on a drive during activity - the leader =
breakes then. Have operators use tapes with robtest or the control =
pannel on the robot but never let them again, open the door on the =
robot, thats what has been happening - the open door, press unload - =
they pull the handle - immediate break of the leader - - joke take the =
keys to the robot and use volmgr/robtest to unload / move tapes.

Paul,
Powercycling the drive has worked most of the time. If there
are red lights on the front of the drive, you need to call in
to STK to have them remove and possible replace the drive.
Once I had a tape snap the leader spindle off with 1/4 the tape
in the drive. It shredded the tape completely. I've had a few
other tapes almost snap, and had to be removed by STK. I did not
return the tapes to use.
