Eject tape and many options

Dear Guy's

I'm using this command to eject the tape and I got many options

/root>mt -f /dev/rmt0 eject
mt: 0511-575 eject is not a recognized subcommand.
Usage: mt [-f Device] Subcommand [Count]
Valid subcommands are:
weof
eof
fsf
bsf
fsr
bsr
rewind
offline
rewoffl
status

Can anyone explain the meaning of each one ?

1.   weof
   

2.   eof
   

3.   fsf
   

4.   bsf
   

5.   fsr
   

6.   bsr
   

7.   rewind
   

8.   offline
   

9.   rewoffl

You might like to try the tctl command instead, or it could be that your tape device does not support this function:
