Why not use mtx to figure out the tape status?
mtx -f /dev/sg1 status
Storage Changer /dev/sg1:2 Drives, 48 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 43 Loaded):VolumeTag =
JX2072L3
Data Transfer Element 1:Full (Storage Element 6 Loaded):VolumeTag =
AX7578L4
Storage Element 1:Full :VolumeTag=AX7336L4
Storage Element 2:Full :VolumeTag=AX7577L4
Storage Element 3:Full :VolumeTag=AX7339L4
Storage Element 4:Full :VolumeTag=AX7337L4
Storage Element 5:Full :VolumeTag=AX7335L4
Storage Element 6:Empty
Storage Element 7:Full :VolumeTag=AX7320L4
Storage Element 8:Full :VolumeTag=AX7328L4
Storage Element 9:Full :VolumeTag=AX7329L4
Storage Element
10:Full :VolumeTag=AX7576L4
Storage Element 11:Full :VolumeTag=JX2050L3
