The robotic library device could not be opened. The specific case could be one of the following:
The robot device, path, or library name in the device configuration may not be valid.
The robotic device may be incorrect, such as a UNIX and Linux device file that is not of a character special file format.
The robotic daemon/process lock file could not be opened or a lock obtained.
The open operation on the device or through the API interface (such as NDMP) failed.
Stop any robot test utilities that may be running, since they have the lock on the robotic device when they are active.
Check the configuration of the robot against the recommended configuration as indicated in the documentation for robot configuration.
Check the health of the robotic device by using a robot test utility, then close the test utility when finished.
Check for the existence and permissions of the lock file itself and the lock file directory, which is /usr/openv/volmgr/misc/vmd.lock (UNIX and Linux) or install_path\Volmgr\misc\vmd.lock (Windows). Create the directory/folder and adjust the permissions as needed so that the robotic daemon/process can use the lock file. Stop and restart ltid (the device daemon on UNIX and Linux or the NetBackup Device Manager service on Windows).
