Hi,
After more testing done today, this looks like a mtx bug: issuing command "mtx
load 1 0" correctly loads tape from the changer slot 1 into the first tape
drive. However, "mtx status" then shows this tape drive as loaded with slot 45
instead (but also correctly lists slot 1 as empty):
# mtx status
Storage Changer /dev/changer:2 Drives, 45 Slots ( 1 Import/Export )
Data Transfer Element 0:Empty
Data Transfer Element 1:Empty
Storage Element 1:Full :VolumeTag=A00000L5
Storage Element 2:Full :VolumeTag=A00001L5
<...>
# mtx load 1 0
Loading media from Storage Element 1 into drive 0...done
# mtx status
Storage Changer /dev/changer:2 Drives, 45 Slots ( 1 Import/Export )
Data Transfer Element 0:Full (Storage Element 45 Loaded):VolumeTag = A00000L5
Data Transfer Element 1:Empty
Storage Element 1:Empty
Storage Element 2:Full :VolumeTag=A00001L5
Storage Element 3:Full :VolumeTag=A00002L5
<...>
Unfortunately, mtx project seems dead, so no updates...
