Hi,

What happens when you kill netbackup and just run robtest, I assume the 
same issues?

Have you enabled e.g. VERBOSE in /usr/openv/volmgr/debug and created all 
of the directorid, e.g. ltid to try and find out more information?

The robot you say was rebooted, what type of robot is it?  Can you login 
to the robot via SSH or robot console software to check the fiber link?

Justin.
