That means communications problems, may be the fibre cable is broken or some other issue.

Chek all the components.

> We have STK L180 tape library connected to a Solaris 10 master/media server.Until 3 days back we were able to see tape drives and robots  and now the robot has disappeared.  Initially when we were seeing the robot, we were not able to configure it in netbackup. when we did a scan -changer on that robot it used to report "0" drives and "0" slots whereas the library has 6 drives and 84 slots. To fix that problem Symantec suggested rebuilding the sg driver and told me to remove everything from /dev/rmt/*cbn and /dev/sg directories. After doing that and rebooting the master with a reconfiguration we lost the robot.
