Hello,
I've installed new backups system on same hardware. The old system
was lenny with an bacula 2.x release working well with this drive.
After installing I've tried to test all the tape drives. For my DLT-8000
tape drive in my Library I have no problem registred and the test has
been ended successfully.
But for my SuperDLT1 internal tape drive if I start the test the cartrige
will ejects at Append files test and then I got messages the test has
been failed with an, tata, "No medium found" error.
I googled about the problem and found one thread from 2007, but there is
no real solution shown nor an answer of an hint to disable "Offline on umount"
to no, which is allready performed by me.

In /var/log/messages I found multiple times this message but it shows only
that the cartridge has been ejected, too:

[current]
Sep 15 09:48:51 backup kernel: [71749.811903] st2: Add. Sense: Medium not
present
...
I can go to the drive and insert the cartrige again, but If I restart the test,
the problem will be again fail near the same time at the same test.
Here the part from my bacula-sd.conf:
Device {
Name = "SDLT-1"
Drive Index = 0
Media Type = "SDLT-1"
Archive Device = /dev/tape/by-path/xen-pci-0-pci-0000:00:01.0-scsi-0:0:1:0-nst
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = yes;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = no
# Enable the Alert command only if you have the mtx package loaded
Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
Spool Directory = "/tmp"
Offline On Unmount = No
Requires Mount = Yes
Mount Command = "mt -f %a load"
Unmount Command = "mt -f %a eject"
Maximum Spool Size = 536870912
}
Remember, with an older release of bacula (from Etch on os Lenny) I didn't had
the problem.
OS is now Squeeze with Bacula from 5.0.2 from Squeeze, too.
Help is welcome. Thank you.
MfG...
Pierre
