Media Manager status code 51
Message: cannot auto-eject this robot type
Explanation: A request to change volume residence with media eject was sent to vmd, but the volume's robot type does not support automated media eject. (vmd is the NetBackup Volume Manager daemon on UNIX and Linux or NetBackup Volume Manager service on Windows.)
Recommended Action:
Examine the command output, debug logs, and system logs for a more detailed message on the error.
See "Setting Media Manager debug logging to a higher level" in the NetBackup Logging Reference Guide.
Ensure that the change volume residence requests are not sent to vmd on a system that runs an older, incompatible software version level. (The change volume residence requests are requests with eject for the robot type that is involved with a newer release version level.)
