Summary: Tape is not loaded automatically due to a Btape
error.
Description:
I am using a compaq StorageWorks SSL2020. almost everything is working
except if the tape drive ( Compaq SDX-700c ) does not contains a tape when
I start a client backup the following error is reported.
mount storage=CompaqSSL2020
3301 Issuing autochanger "loaded? drive 0" command.
3302 Autochanger "loaded? drive 0", result: nothing loaded.
3901 open device failed: ERR=dev.c:433 Unable to open device "SDX700c"
(/dev/nst0): ERR=No medium found
it sounds like btape cannot access the drive, but if a tape is loaded
btape does not returns any error.
Tape block granularity is 1024 bytes.
btape: butil.c:285 Using device: "/dev/nst0" for writing.
17-Dec 01:14 btape JobId 0: 3301 Issuing autochanger "loaded? drive 0"
command.
17-Dec 01:14 btape JobId 0: 3302 Autochanger "loaded? drive 0", result is
Slot 3.
17-Dec 01:14 btape JobId 0: 3301 Issuing autochanger "loaded? drive 0"
command.
17-Dec 01:14 btape JobId 0: 3302 Autochanger "loaded? drive 0", result is
Slot 3.
btape: btape.c:368 open device "SDX700c" (/dev/nst0): OK

I changed 1 thing.
The definition of my device in /etc/bacula/bacula-dir.conf
- Device = SDX700c
+ Device = CompaqSSL2020
problem is not solved ( still got errors when drive initialy empty ). but
I saw that if a tape is inserted in the drive, Bacula will eject it and
mount an appropriate volume.

as a test, I installed the stable version from debian's repos. yesterday,
and there is no problem when you test the configuration with Btape. no
errors reported even if the drive is empty.

What Linux distribution/version are you using?
What Linux tape driver are you using to access the tape? (see output from
lsmod command).
Is there some reason why this bug is marked "private" for the view status?

BTW we ( a friend of mine and I ) have followed your great bacula
presentation at the FOSDEM begin this year. Great job you have done. thank
you very much.
Oh yeah, I don't know why the private checkbox was flagged.

In looking this over, I don't think there is any problem or bug with
Bacula, but most likely you have not done an "update slots" command and/or
you forgot to indicate in your Director's conf file that the Storage device
is an autochanger, because normally with an autochanger, the mount command
will ask you what slot you want loaded. In looking at your Storage resource
for the Dir, I do not see the "Autochanger = yes" directive.
I also think you are confusing btape with Bacula. The two are separate
programs. The Bacula SD does not use btape for any of its operations -- in
fact, you cannot run Bacula and btape at the same time. If you do, you
will have a drive conflict -- unless you unmount the drive in Bacula
first.
This looks like a support problem to me, and if my comments above don't
resolve it, most likely www.bacula.org -> Support will get you going.
Thanks for you kind comments on my FOSDEM talk :-)

That will be the problem. I have set the autochanger directive in
bacula-sd.conf but not in bacula-dir.conf.
I will test that tonight at home and let you know if it solve my problem.
Anyway, Thank you very much for your support.
Vincent.

Hi kern,
The Autochanger = yes, was indeed the solution. I have put the line in my
bacula-dir.conf and started the beast. Now tapes are automatically picked
from the loader and put in the drive.
Bacula is a great tool !
A very big thank you for your support. If I can be from any help, do not
hesitate to ask me.
Vincent.
