I have a similar setup with the Dell TL2000 attached via SAS on RedHat
Enterprise Linux but I get results like yours when I run mtx on the drive not
the library. You should try the command from the command line using the -f
attribute on /dev/sg2 and /dev/sg3 directly even though it looks like sg3
should be the changer in your system. Post your results back here please.
mtx -f /dev/sg2 status
mtx -f /dev/sg3 status
my setup:

This configuration in bacula-sd.conf works for me:
# Definition of LTO-4 tape storage device
Autochanger{
Name = TL2000
Device = LTO-4
Changer Device = /dev/sg4
Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
}
Device{
Name = LTO-4
Drive Index = 0
Autochanger = yes
#Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
Device Type = Tape
Media Type = LTO-4
LabelMedia = yes
Archive Device = /dev/nst0
Always Open = yes
AutomaticMount = yes
RemovableMedia = yes
RandomAccess = no
}
You may have noticed that my drive is defined as nst0 not sg3
I get a quick response to mtx -f /dev/sg3 status but running that on /dev/nst0
seems to hang forever, I have to ctrl-c it.
yes, my ulcer went away once I got it running ;-)
