All:
In *BSD, sa(4)/mt(4) devices can't be fopen()'d until they have media
loaded.
So, when you issue "mount" command in bconsole(8), and the autochanger
doesn't have a tape loaded, why would it try to access the tape drive
w/o issuing a load command first?
I'm looking at the code a bit lost get_autochanger_loaded_slot() is
called by autoload_device() on line 170 of stored/autochanger.c
if (loaded != slot)
try_to_unload
I think in this case, there should be a case for:
if (loaded = 0) -- nothing loaded.
- Don't try to unload
- Load
It's like something in unload_autochanger(), for some reason, is trying
to access the drive.
* mount
The defined Storage resources are:
1: Bar
2: Foo
3: TapeChanger
Select Storage resource (1-3): 3
Enter autochanger slot: 0
3301 Issuing autochanger "loaded? drive 0" command.
3302 Autochanger "loaded? drive 0", result: nothing loaded.
3901 Unable to open device "Ultrium" (/dev/nsa0): ERR=dev.c:432 Unable
to open device "Ultrium" (/dev/nsa0): ERR=Device not configured
Error 3901 only happens in stored/dircmd.c mount_cmd(). I don't see the
path between autoload_device() and mount_cmd().
Also, we seem to be missing the step in "mount" where we actually load
the tape into the drive :)
Is there maybe another CLI command hidden/undocumented?
