I had a similar issue when I moved to Mint 18 with the tape device.
This works with kernel 4.10 and later. Copy /lib/udev/rules.d/60-
persistent-storage-tape.rules to /etc/udev/rules.d and make a change as
shown:
diff -n /lib/udev/rules.d/60-persistent-storage-tape.rules
/etc/udev/rules.d/60-persistent-storage-tape.rules
d9 1
a9 2
SYMLINK+="changer"
# SYMLINK+="tape/by-id/scsi-$env{ID_SERIAL}"
This created /dev/changer as a link to the /dev/sg<x> device that will
be consistent every time the system is booted.
