Robotic processes
A NetBackup robotic process and possibly a robotic control process exist on a NetBackup media server for each robot that you install, as follows:
Every media server that has a drive in a robotic library has a robotic process for that robotic library. The robotic process receives requests from the NetBackup Device Manager (ltid) and sends necessary information directly to the robotics or to a robotic control process.
Robotic control processes exist only for the robot types that support library sharing (or robot sharing).
When the NetBackup Device Manager starts, it starts the robotic processes and the robotic control processes for all of the configured robots on that host. When the Device Manager stops, the robotic processes and the robotic control processes stop. (On UNIX, the name is Media Manager Device daemon.)
You can start and stop the Device Manager manually by using the NetBackup Administration Console as follows:
In the NetBackup Activity Monitor Daemons tab, select it and then select or .
Select Devices in the right pane and then select .
, , or
In addition, the NetBackup Commands Reference Guide describes commands to control the robotic processes that run on Windows media servers.
You can determine if a robotic process or robotic control process is active by using the NetBackup Activity Monitor Processes tab.
You can determine the control state of NetBackup by using the Device Monitor Drive paths pane or Drive status pane. If the value in the Control column for a drive shows the control mode, the robotic process is running and the drive is usable. For example, for a TLD robot the control mode is TLD.
Other values such as AVR or DOWN may indicate that the drive is unusable. For the possible values and their explanations, see the online Help for the Device Monitor.
