[Stgt-devel] Bug report mediachanger ?

[Mark Harvey]

You need to ask the maintainer of the mtx this question.

Using the tgt-core-test script as my 'bench' configuration, I get the
following
# mtx --version
mtx version 1.3.11
# mtx -f /dev/sg7 status
  Storage Changer /dev/sg7:3 Drives, 13 Slots ( 5 Import/Export )
Data Transfer Element 0:Empty
Data Transfer Element 1:Empty
Data Transfer Element 2:Empty
      Storage Element 1:Full :VolumeTag=ABC123
      Storage Element 2:Empty:VolumeTag=
      Storage Element 3:Full :VolumeTag=ULT001L3
      Storage Element 4:Empty:VolumeTag=
      Storage Element 5:Empty:VolumeTag=
      Storage Element 6:Empty:VolumeTag=
      Storage Element 7:Empty:VolumeTag=
      Storage Element 8:Empty:VolumeTag=
      Storage Element 9 IMPORT/EXPORT:Empty:VolumeTag=

      Storage Element 11 IMPORT/EXPORT:Empty:VolumeTag=

      Storage Element 12 IMPORT/EXPORT:Empty:VolumeTag=

      Storage Element 13 IMPORT/EXPORT:Empty:VolumeTag=

For the media changer I defined three drives starting at address 1,
one robot arm at address 16, ten tape slots starting at 1024, and five
import/export elements at address 32.

However, when I use mtx for the status (mtx -f /dev/sg4 status) I get:

  Storage Changer /dev/sg4:3 Drives, 13 Slots ( 5 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = 
ABC123                        
Data Transfer Element 1:Empty
Data Transfer Element 2:Empty
      Storage Element 1:Empty:VolumeTag=                               
      Storage Element 2:Full :VolumeTag=ULT001L3                      
      Storage Element 3:Empty:VolumeTag=                               
      Storage Element 4:Empty:VolumeTag=                              
      Storage Element 5:Empty:VolumeTag=                              
      Storage Element 6:Empty:VolumeTag=                              
      Storage Element 7:Empty:VolumeTag=                              
      Storage Element 8:Empty:VolumeTag=                              
      Storage Element 9 
IMPORT/EXPORT:Empty:VolumeTag=                              
      Storage Element 10 
IMPORT/EXPORT:Empty:VolumeTag=                              
      Storage Element 11 
IMPORT/EXPORT:Empty:VolumeTag=                              
      Storage Element 12 
IMPORT/EXPORT:Empty:VolumeTag=                              
      Storage Element 13 IMPORT/EXPORT:Empty:VolumeTag=                

Why doesn't show mtx the proper addresses as defined at setup,
i.e. first storage element -> 1024?

Thanks,

Albert
