Remove the drives with the missing paths, readd with device wizard. Make sure when you select the media server, also select the robot control host if it is a separate server.
This will restart ltid on both servers, so ensure no jobs are running.

The OS sees the drives:
[2:0:0:0] tape HP Ultrium 4-SCSI R500 /dev/st4
[2:0:0:1] tape HP Ultrium 4-SCSI R500 /dev/st5
[2:0:0:2] tape HP Ultrium 4-SCSI R500 /dev/st6
[2:0:0:3] tape HP Ultrium 4-SCSI R500 /dev/st7
[4:0:0:0] tape HP Ultrium 4-SCSI R500 /dev/st0
[4:0:0:1] tape HP Ultrium 4-SCSI R500 /dev/st1
[4:0:0:2] tape HP Ultrium 4-SCSI R500 /dev/st2
[4:0:0:3] tape HP Ultrium 4-SCSI R500 /dev/st3
I ran the scan, It looks like it sees all 8 drives too:
