Yes, I should be paying more attention to these details.....ugh.....
I appreciate the help running a dump right now. 
Final question hopefully ...
Are the any configuration changes needed to have Amanda use both drives inside 
the tape library?


mtx -f /dev/scsi/changer/c3t3d1 status
  Storage Changer /dev/scsi/changer/c3t3d1:2 Drives, 12 Slots ( 1 Import/Export 
)
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = EGV002
Data Transfer Element 1:Empty
      Storage Element 1:Empty:VolumeTag=
      Storage Element 2:Full :VolumeTag=EGV003
      Storage Element 3:Full :VolumeTag=EGV004
      Storage Element 4:Full :VolumeTag=EGV005
      Storage Element 5:Full :VolumeTag=EGV006
      Storage Element 6:Full :VolumeTag=EGV007
      Storage Element 7:Full :VolumeTag=EGV008
      Storage Element 8:Full :VolumeTag=EGV009
      Storage Element 9:Full :VolumeTag=EGV010
      Storage Element 10:Full :VolumeTag=EGV011
      Storage Element 11:Full :VolumeTag=EGV012
      Storage Element 12 IMPORT/EXPORT:Empty:VolumeTag=

Amanda.conf
tpchanger "chg-zd-mtx" # the tape-changer glue script

tapedev "/dev/rmt/1n"  # the no-rewind tape device to be used

changerfile "/etc/amanda/Full/changer.conf"
changerdev "/dev/scsi/changer/c3t3d1"


cat changer.conf
firstslot=1
lastslot=11
driveslot=0
cleanslot=-1
autoclean=0
autocleancount=99
havereader=1
offline_before_unload=0
initial_poll_delay=0

Or will it automatically load another tape in the second drive , so far it has 
not.

Thanks again for the information

^^^^^^^^^^^^^^^^^

you gotta read these things.  ;-)

On my system, I have:

mormyrid:amanda$ ls -l /dev/scsi/changer

lrwxrwxrwx   1 root     root          52 Jan 16  2007 c7t0d0 -> 
../../../devices/pci@1f,2000/scsi@1/sgen@0,0:changer

mormyrid:amanda$ ls -l /devices/pci@1f,2000/scsi@1/sgen@0,0:changer

crw-rw-rw-   1 root     sys      151, 48 Jan 16  2007 
/devices/pci@1f,2000/scsi@1/sgen@0,0:changer


I never modified permissions on any of this. I just edited the 
/kernel/drv/sgen.conf, did a touch /reconfigure, and rebooted. It worked 
with mtx immediately.
