After I posted the original mail, I did add Max Concurrent Jobs to the
Storage definition in bacula-dir.conf. I was missing that originally:

Storage {
 Name = T200-1
# Do not use "localhost" here
 Address = sd.site.com                # N.B. Use a fully qualified name here
 SDPort = 9103
 Password = "xxxxxxxxxxxx"
 Device = "Drive_1"
 Device = "Drive_2"
 Device = "Drive_3"
 Media Type = LTO-4
 Autochanger = yes
 Maximum Concurrent Jobs = 20
}


After a lot of reading through the mailing list, I came across a post
that hinted there was a problem with running "label barcodes" on
anything but the first drive, but running simultaneous jobs DID work .
I was assuming that since I couldn't tell bconsole which drive I
wanted loaded or use (such as in label barcodes, mount, umount, etc)
it was wasn't seeing my other drives. I ran a test backup with
multiple jobs and 2 drives were used, so I was assuming (with out
actually testing) that something was incorrect.

Which leads to my other problem: I ran a third job at the same time
and bacula prompted me for a labeled tape which was in the library and
in the scratch pool but didn't load it into the third drive. That's
where my problem occurs. How can I load it? bconsole ignores the drive
designation when you run "mount". I tried to load the tape through the
library interface, but bacula didn't recognize that the tape was
loaded. Not sure how to get around that one yet.

It looks like something goes wrong somewhere in the ua_select.c file.
I've looked at the section for getting the drive number:

int get_storage_drive(UAContext *ua, STORE *store)
{
  int i, drive = -1;
  /* Get drive for autochanger if possible */
  i = find_arg_with_value(ua, "drive");
  if (i >=0) {
     drive = atoi(ua->argv[i]);
  } else if (store && store->autochanger) {
     /* If our structure is not set ask SD for # drives */
     if (store->drives == 0) {
        store->drives = get_num_drives_from_SD(ua);
     }
     /* If only one drive, default = 0 */
     if (store->drives == 1) {
        drive = 0;
     } else {
        /* Ask user to enter drive number */
        ua->cmd[0] = 0;
        if (!get_cmd(ua, _("Enter autochanger drive[0]: "))) {
           drive = -1;  /* None */
        } else {
           drive = atoi(ua->cmd);
        }
    }
  }
  return drive;
}

but I don't see anything obvious yet.
