i wrote "mt -f /dev/st0 rewind" but it returns silent , no error messg , no attempt on tape to rewind it.

i am confused why ?

it just comes to prompt without doing anything, no activity , no message at all.

i checked "mt -f /dev/st0 offline" to confirm "mt" function though.
It works and tape ejects immediately .

scratching my head why not with "rewind" option!

awaiting your reply

thanks and regards
