1 , update Mapping file

in the original also encountered type of failure, by updating Mapping file, trouble-shooting, this time not so lucky.

2 , lsscsi-g View Tape situation

below for the normal environment, today's environment is missing the red part, through MTX also see Tape the information, only see the robot and tape

[2:0:8:0] mediumx SPECTRA PYTHON 550V - /dev/sg11 [2:0:9:0] tape IBM ult3580-td4 550V /dev/st4 /dev/ Sg7

so suspicion is the driver of the problem, through the field engineers understand that installed the IBM the drive, in the original project, in the LINUX the environment was never installed, so the driver was unloaded.

3 , after unloading the drive normally

finally in Google search, found there are ready-made.
