in wat situations we can use robtest....
When you need to operate robots from command line or for test proposes.
I use it when I'm installing or troubleshooting robotic devices and with I need to change media's slot position. Other use is to try removing tapes from drives.
Extract from NBU Admin Guide II:
You can verify your device configuration by running the Device Configuration wizard. However, some details of a device configuration cannot be validated without attempting tape mounts. You can use the NetBackup robtest utility to mount tapes and validate the configuration.
Have a look at this TechNote for robtest examples:
Supporting Storage Foundation and VCS on Unix and Windows as well as NetBackup on Unix and Windows

Robtest will interfere with robotic operations, preventing any mounts or dismounts from occurring while running. Please exit the utility when testing has been completed.
