I find that it is sufficient just to do a mount after the eject
operation, eg:

"
#!/bin/sh
TAPEDEV=/dev/tape/by-path/pci-0000:01:08.0-scsi-0:0:6:0-nst-nst
BCONSOLE=/usr/bin/bconsole
SDNAME=bitvs2

echo "unmount storage=bitvs2-tape-sd" | $BCONSOLE -n -c
/etc/bacula/bconsole.conf >/dev/null 2>/dev/null
ssh $SDNAME "/bin/mt -f $TAPEDEV eject 2>/dev/null >/dev/null"
echo "mount storage=bitvs2-tape-sd" | $BCONSOLE -n -c
/etc/bacula/bconsole.conf >/dev/null 2>/dev/null
"

even though there is no media, bacula still takes control of the tape
drive again on mount and just uses whatever media is in there when the
next job starts. My SD and DIR are different machines, hence the
requirement to use ssh rather than just use mt directly.
