How are you trying to offline the drives? Are you just trying to unload
through Networker, or are you trying to reset the jukebox (ie nsrjb -H)
through Networker? Tape drives do not get ejected during a reset, but
Networker will still sit there trying to move the tapes from the drive
back to the slot and you have to do your "mt ...... offline" trick to
eject the drives.
