The number above is 8 times the SCSI ID. Thus
slave

for the tape devices are as follows:
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
crw-rw-rw- 1 root
Thus, the mapping from SCSI ID's to minor devices is as follows:
SCSI ID Tape Device Major,Minor Device
4
5
3
2
Thus, although (18,4) and (18,5) would correspond to SCSI ID's 4 and 5 respectively,
(18,6) and (18,7) would be used to access SCSI ID's 3 and 2 respectively.
In general to determine the correct minor device numbers it is necessary to know
both the mapping from SCSI ID's to
