I have a Dell PowerVault 124T (LTO3) autochanger that I'm having trouble
connecting to Bacula. I've worked half-way through the default scripts for
installation, and now I want to do the btape tests, but I'm running into
errors on both the changer and the tape drive itself. I'm running Bacula
2.0.3 on SlackWare 10 with Linux kernel 2.6.9. I'm logged-in as root, and I
still have this trouble when I try to test my tape drive:
[EMAIL PROTECTED]:~/bacula/bin# ./btape -c bacula-sd.conf /dev/sg2
Tape block granularity is 1024 bytes.
btape: butil.c:286 Using device: "/dev/sg2" for writing.
27-Apr 14:33 btape: 3301 Issuing autochanger "loaded? drive 0" command.
27-Apr 14:33 btape: 3991 Bad autochanger "loaded? drive 0" command: ERR=No
such file or directory.
Results=
27-Apr 14:33 btape: Fatal Error at device.c:280 because:
dev open failed: dev.c:425 Unable to open device "LTO-3" (/dev/sg2):
ERR=Operation not permitted
27-Apr 14:33 btape: btape Fatal error: butil.c:195 Cannot open "LTO-3"
(/dev/sg2)
My first assumption is that I neglected to mount a tape, so I examine the
autochanger's status, and I see that there's nothing wrong here:
[EMAIL PROTECTED]:~/bacula/bin# mtx -f /dev/sg3 status
Storage Changer /dev/sg3:1 Drives, 16 Slots ( 0 Import/Export )
Data Transfer Element 0:Full (Storage Element 1 Loaded):VolumeTag = 000010L3
Storage Element 1:Empty
Storage Element 2:Full :VolumeTag=000011L3
Storage Element 3:Full :VolumeTag=000012L3
Storage Element 4:Full :VolumeTag=000013L3
Storage Element 5:Full :VolumeTag=000014L3
Storage Element 6:Empty
Storage Element 7:Empty

Storage Element 10:Empty
Storage Element 11:Empty
Storage Element 12:Empty
Storage Element 13:Empty
Storage Element 14:Empty
Storage Element 15:Empty
Storage Element 16:Empty
If I unmount the tape and try again, I get the same error message (I'll
spare you this listing.) Here's how I've edited the tape volume -related
section of bacula-sd.conf:
Autochanger {
Name = Autochanger
Device = LTO-3
Changer Command = "/home/kern/bacula/bin/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg3
}
Device {
Name = LTO-3 #
Drive Index = 0
Media Type = LTO-3
Archive Device = /dev/sg2
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'"
# If you have smartctl, enable this, it has more info than tapeinfo
Alert Command = "sh -c 'smartctl -H -l error %c'"
}
and here's my bacula-dir.conf:
# Definition of LTO3 tape storage device
Storage {
Name = LTO-3
Do not use "localhost" here
Address = epimetheus.ap.com # N.B. Use a fully qualified
name here
SDPort = 9103
Password = "66I2GryjVO6SDpEt9/iEtXiryRYEMPjwon+9rVezMszM" #
password for Storage daemon
Device = LTO-3 # must be same as Device in Storage
daemon
Media Type = LTO-3 # must be same as MediaType in Storage
daemon
Autochanger = yes # enable for autochanger device
}
If I try to isolate the tape drive by setting "Autochanger = no" in both
files and commenting-out the autochanger section in the first file, I get
this error instead:
[EMAIL PROTECTED]:~/bacula/bin# ./btape -c bacula-sd.conf /dev/sg2
Tape block granularity is 1024 bytes.
btape: butil.c:286 Using device: "/dev/sg2" for writing.
27-Apr 14:41 btape: Fatal Error at device.c:280 because:
dev open failed: dev.c:425 Unable to open device "LTO-3" (/dev/sg2):
ERR=Operation not permitted
27-Apr 14:41 btape: btape Fatal error: butil.c:195 Cannot open "LTO-3"
(/dev/sg2)
I've looked through the documentation and done a little google searching,
but I don't have a clue yet. Can anyone suggest something more I can try?
