If it is Linux have a look in /dev/tape/by-id/
For example in our case:

lrwxrwxrwx 1 root root  10 Nov 19 18:23 scsi-350014380032b4c68 -> ../../sg10
lrwxrwxrwx 1 root root   9 Nov 19 18:23 scsi-350014380032b4c69 -> ../../st0
lrwxrwxrwx 1 root root  10 Nov 19 18:23 scsi-350014380032b4c69-nst ->  
../../nst0

so we choose /dev/tape/by-id/scsi-350014380032b4c69-nst which has also  
the advantage of not changing if devices are added/removed as it is  
the case with /dev/sgX.

Regarding your problem with the device/bus reset you should carefully  
check cabeling and adapter firmware/driver.
