1- mt -t /dev/rmt/xmn rew # rewind

2- tar cf /dev/rmt/xmn /file_system # use no rewind device
3- tar cf /dev/rmt/xmn /file_system # use no rewind device

recovery :

1- mt -t /dev/rmt/xmn rew # rewind

# now you can restore session 1:

tar xvf /dev/rmt/xmn # work allways with no rewind device

# and the second:
tar xvf /dev/rmt/xmn # work allways with no rewind device

#or skip first session and restore only the second:
1- mt -t /dev/rmt/xmn rew # rewind
2- mt -t /dev/rmt/xmn fsf 1 # Forward Skip File(s) #skips

tar ....
