Explanation: Operator has attempted to assign a pending tape mount request to a drive that is in a robot that is up.
Recommended Action: A request for non-robotic media may have caused a pending request in the device monitor, and the operator has assigned the request to a drive that is not a standalone drive. This error is not fatal. The request will pend again in the NetBackup device monitor. Assign the pending mount to a standalone drive or to a drive that is in AVR mode (non-robotic).
