We have a Overland Storage Neo 8000 with two FC LTO3 drives, and almost
every time the SD is rebooted, the drives swap places. Drive0 will be
/dev/st0 and Drive1 will be /dev/st1, then sometimes after reboot Drive0
will be /dev/st1 and Drive1 will be /dev/st0. It doesn't happen all the
time and I thought udev would take care of keeping the drive the same
across reboots like the Ethernet cards. Does anyone have some wisdom
that they can impart to me on this problem?

 

Relevant part of bacula-sd.conf:

Autochanger {

  Name = Neo8000

  Device = Drive-0

  Device = Drive-1

  Changer Command = "/etc/bacula/scripts/mtx-changer %c %o %S %a %d"

  Changer Device = /dev/sg4

}

 

Device {

  Name = Drive-0                      #

  Drive Index = 0

  Media Type = LTO3

  Archive Device = /dev/st1

  AutomaticMount = yes;               # when device opened, read it

  AlwaysOpen = yes;

  RemovableMedia = yes;

  RandomAccess = no;

  AutoChanger = yes

  Spool Directory = /backup/spool

  Maximum Network Buffer Size = 65536

  # 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'"

}

 

Device {

  Name = Drive-1                      #

  Drive Index = 1

  Media Type = LTO3

  Archive Device = /dev/st0

  AutomaticMount = yes;               # when device opened, read it

  AlwaysOpen = yes;

  RemovableMedia = yes;

  RandomAccess = no;

  AutoChanger = yes

  Spool Directory = /backup/spool

  Maximum Network Buffer Size = 65536

  # 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'"

}

 

Thanks,
