I have several tapes which were marked "Error" by bacula due to backups 
in progress being interrupted by the storage daemon becoming 
unresponsive.  I'm trying to restore them to a usable state using bscan 
per 
http://www.bacula.org/en/rel-manual/Volume_Utility_Tools.html#SECTION003973000000000000000.

I have a two-drive autochanger on the system in question.  I am asked to 
do a manual mount of the tape, and I do so, but I am still told that the 
tape is not mounted properly for reading:

[root@uwharrie bacula]# bscan -V MSR148L3 -s -m -v /dev/nst0
bscan: butil.c:282 Using device: "/dev/nst0" for reading.
10-Jul 09:50 bscan JobId 0: Invalid slot=0 defined in catalog for Volume 
"MSR148L3" on "Drive-1" (/dev/nst0). Manual load my be required.
10-Jul 09:50 bscan JobId 0: 3301 Issuing autochanger "loaded? drive 0" 
command.
10-Jul 09:50 bscan JobId 0: 3302 Autochanger "loaded? drive 0", result 
is Slot 6.
10-Jul 09:55 bscan JobId 0: Warning: acquire.c:207 Read open device 
"Drive-1" (/dev/nst0) Volume "MSR148L3" failed: ERR=dev.c:433 Unable to 
open device "Drive-1" (/dev/nst0): ERR=Device or resource busy

10-Jul 09:55 bscan JobId 0: Invalid slot=0 defined in catalog for Volume 
"MSR148L3" on "Drive-1" (/dev/nst0). Manual load my be required.
Mount Volume "MSR148L3" on device "Drive-1" (/dev/nst0) and press return 
when ready:


How do I convince bscan that my tape is indeed properly mounted, when 
even bconsole says it is:

Device status:
Autochanger "PX502" with devices:
   "Drive-1" (/dev/nst0)
   "Drive-2" (/dev/nst1)
Device "VG1-LV0" (/var/bacula/spool) is not open.
Device "Drive-1" (/dev/nst0) is mounted with:
    Volume:      MSR148L3
    Pool:        *unknown*
    Media type:  LTO-3
    Slot 6 is loaded in drive 0.
    Total Bytes Read=129,024 Blocks Read=2 Bytes/block=64,512
    Positioned at File=0 Block=0
Device "Drive-2" (/dev/nst1) is not open.
    Drive 1 status unknown.
