Yes, this is what your mail really looks like, due to the fact that
it's MIME-encoded. Plain ASCII text mail is much nicer...
Anyway...
=> Hello Everyone,
=>
=> I?m new to using Bacula and am having a little trouble setting up the
=> configurations.
Your trouble report is utterly lacking in some important and very basic
information,
such as:
OS type & version
Bacula version
mtx version
However, since I've got the same tape drive, there's still hope.
=>
=>
=> When I run cat /proc/scsi/scsi I get the following back
OK, from that, I'm guessing that you're running [Linux|Unix|Solaris], but
probably not AIX.

=> Host: scsi1 Channel: 02 Id: 00 Lun: 00
=> Vendor: DELL Model: PERC 5/i Rev: 1.03
=> Type: Direct-Access ANSI SCSI revision: 05
Looks good so far.
=>
=> Next I run mtx ?f /dev/sg0 status
Depending on your system, the changer device may not always be at /dev/sg0, as
the SCSI device ordering can change each time the system is booted. For example,
my pv132t was on /dev/sg10, but it's on /dev/sg7 now, due to the device
discovery order on our SAN.
While this doesn't happen all the time, it's very inconvenient and difficult to
catch. I've written a script (search the Bacula archives for "create_changer")
to help with this issue. In any case, that doesn't sound like the problem you're
describing.

Poor MIME encoding, if you really meant "mtx -f".
=>

=> Attached Changer API: No
=>
=> /mtx ?f /dev/sg2 inquiry shows:
=> Product Type: Tape Drive
OK.
=> Vendor ID: 'IBM '
=> Product ID: 'ULTRIUM-TD2 '
That's an LTO-2 tape drive.
=> Revision: '37RH'
=> Attached Changer API: No
=>
=> /mt ?f /dev/nst0 status shows:
=> SCSI 2 tape drive:
OK.
=> File number=-1, block number=-1, partition=0.
=> Tape block size 0 bytes. Density code 0x0 (default).
=> Soft error count since last status=0

=>
=>
=>
=> In bacula-sd.conf I have the following setup:
=>
=> Autochanger {
=> Name = Autochanger
=> Device = DellPowerVault132T
=> Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
=> Changer Device = /dev/sg0
=> }
Missing the "Device" definitions...have you RTFM?
=>
=> Device {
=> Name = DellPowerVault132T
=> LabelMedia = yes
=> Drive Index = 0
=> Media Type = LTO-3
=> Archive Device = /dev/nst0
Why do you have definitions for /dev/nst0 and /dev/tape[01]? That makes bacula
think that you have 3 tape drives...two LTO2 and one LT03. Where did this 3rd
drive (supposedly inside a changer that only holds 2 drives) come from?
Do you have links from /dev/nst0 => /dev/tape1 and /dev/nst1 /dev/tape0 (that's
how my links are set up, so that "drive 0" corresponds to /dev/
tape0...otherwise they are swapped logically).
=> AutomaticMount = yes;
=> AlwaysOpen = yes;
=> RemovableMedia = yes;
=> RandomAccess = no;
=> AutoChanger = yes
=> Hardware End of Medium = No
=> BSF at EOM = yes
=> # Enable the Alert command only if you have the mtx package loaded
=> Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
=> TWO EOF = yes
=> }
=>
=>
=> Also in the bacula-dir.conf I have the following setup:
=> Storage {
=> Name = File
That looks odd to me. Of course, you can name the storage device anything you
want (personally, I'm fond of "Jayne Mansfield"), but I find it confusing to
name the tape device "File". You also need to have the same name as is defined
in the bacula-sd.conf Autochanger directive.
=> # Do not use "localhost" here
=> Address = <<server_name>> # N.B. Use a fully qualified name
=> here
=> SDPort = 9103
=> Password = "<xxx>"
=> Device = DellPowerVault132T
=> Media Type = LTO-3
=> }
=>
=>
=> Does everything look correctly setup?
No. RTFM.
=>
=> When I try to mounting the storage using the Webmin Bacula console I get the
=> following error:
=>
=> Mounting volume on storage device File ..
OK, you're trying to use to LTO3 tape drive at /dev/nst0.
=> Automatically selected Catalog: MyCatalog
=> Using Catalog "MyCatalog"
=> 3301 Issuing autochanger "loaded? drive 0" command.
=> 3302 Autochanger "loaded? drive 0", result: nothing loaded.
No surprise...you're not addressing the autochanger device.
=> 3901 open device failed: ERR=dev.c:433 Unable to open device
That doesn't surprise me.
=> "DellPowerVault132T" (/dev/nst0): ERR=No medium found
Have you checked the output from:
mt -f /dev/nst0 status
mt -f /dev/tape0 status
mt -f /dev/tape1 status
ls -l /dev/tape0 /dev/tape1 /dev/nst0
The responses from those commands should be enough to point you in the right
direction, along with RingTFM.
For reference, my config is:
########################### bacula-sd.conf ###################################
#
# An autochanger device with two drives
#
Autochanger {
Name = pv132t
Device = Drive-0
Device = Drive-1

This is absolutely not guaranteed to work on any other Bacula installation,
even with the same hardware....but it's a good starting point.
RTFM, please.

=> Any help would be appreciated.
