What does lsscsi -g show and does that correspond to your bacula-sd.conf entries? Best regards, UdoHi Udo, yes, I regularily reboot the system for maintenance: sudo lsscsi -g [0:0:0:0] disk Areca ARC-1883-VOL#000 R001 /dev/sda /dev/sg0 [0:0:0:1] disk Areca ARC-1883-VOL#001 R001 /dev/sdb /dev/sg1 [0:0:0:2] disk Areca Data6 R001 /dev/sdc /dev/sg2 [0:0:0:4] disk Areca VOL_Data4 R001 /dev/sdd /dev/sg3 [0:0:16:0] process Areca RAID controller R001 - /dev/sg4 [1:0:0:0] enclosu ATTO VirtualSES 0001 - /dev/sg6 [1:0:1:0] tape IBM ULTRIUM-HH9 R3G1 /dev/st0 /dev/sg7 [1:0:1:1] mediumx BDT FlexStor II 6.21 /dev/sch0 /dev/sg8 That looks very susual and it worked in the last months with sg7 Now, just for the fun of it I used mtx -f /dev/sg8 status additionally and got:
|In Debian if you need a consistent device for the changer across reboots you
will need to setup some udev rules:

ATTRS{vendor}=="BDT "
...
udevadm info -q all -a -n /dev/sg8 | grep -e vendor -e model

SYMLINK+="changer0"
# block device name
# SUBSYSTEM=="block", DRIVERS=="mt", ATTRS{vendor}=="BDT ", ATTRS{model}=="FlexStor II

Beware of the attributes containing white space. There is no need for a changer
block device for now. After reboot you should be able to use /dev/changer0 in
your bacula-sd.conf autochanger setup and it will be consistent.
HTH, Udo
