Hi,

I had a heck of time trying to configure Bacula to work with this Exabyte 1x7 
LTO Autoloader.
I wasn't sure which autochanger device /dev/st0 or /dev/nst0.  When I do #mt -f 
/dev/st0 status and #mt -f /dev/nst0, they all have some good output:
OUTPUT:
SCSI 2 tape drive:
File number=-1, block number=-1, partition=0.
Tape block size 0 bytes. Density code 0x0 (default).
Soft error count since last status=0
General status bits on (50000):
 DR_OPEN IM_REP_EN


When I tried to label a volume, I get the error below.  

*label
Automatically selected Catalog: MyCatalog
Using Catalog "MyCatalog"
Automatically selected Storage: LTO-2
Enter new Volume name: test
Enter slot (0 or Enter for none): 
Defined Pools:
     1: Default
     2: File
     3: Scratch
Select the Pool (1-3): 1
Connecting to Storage daemon LTO-2 at cole:9103 ...
Sending label command for Volume "test" Slot 0 ...
Invalid slot=0 defined in catalog for Volume "" on "LTO-2.0" (/dev/nst0). 
Manual load may be required.

device "LTO-2.0" (/dev/nst0): ERR=No medium found

Label command failed for Volume test.
Do not forget to mount the drive!!!


Below is my -dir.conf configuration

Storage {
  Name = LTO-2
  Address = cole                # N.B. Use a fully qualified name here
  SDPort = 9103
  Password = "QEPdNZ6gTvOqzAmDEVtiX9J5Xb4PYKKNF0BQm/uISqN+"          # password 
for Storage daemon
  Device = LTO-2                      # must be same as Device in Storage daemon
  Media Type = LTO-2                  # must be same as MediaType in Storage 
daemon
  Autochanger = yes                   # enable for autochanger device
  Maximum Concurrent Jobs = 6
}

The -sd.conf configuration

Autochanger {
  Name = LTO-2
  Device = LTO-2.0
  Changer Command = "/root/bacula/bin/mtx-changer %c %o %S %a %d"
  Changer Device = /dev/sg3
}

Device {
  Name = LTO-2.0
  Drive Index = 0
  Media Type = LTO-2
  Archive Device = /dev/st0
  AutomaticMount = yes;               # when device opened, read it
  AlwaysOpen = yes;
  RemovableMedia = yes;
  RandomAccess = no;
  Changer Command = "/root/bacula/bin/mtx-changer %c %o %S %a %d"
  Changer Device = /dev/sg0
  Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
}

Can someone please guide me to the right track?

Thanks

Harry
