I recently had to struggle with a server with several
hot-pluggable SATA drives where depending on the number
of plugged drives the /dev/sg nodes seem to shuffle around.
Recent Linux distributions (namely the udev device management) seems to
have a nice solution to this problem (I am currently running Ubuntu
Feisty). They create symlinks named after the devices serial number,
so in Baculas sd.conf, I have:
Changer Device = /dev/tape/by-id/scsi-200900de6055fa000
Archive Device = /dev/tape/by-id/scsi-350060b000033c0d9-nst
unfortunately, the same udev rules miss the entry to adjust the
tape changer's permissions (/etc/udev/rules.d/40-permissions.rules):
# SCSI devices
SUBSYSTEMS=="scsi", GOTO="scsi_start"
GOTO="scsi_end"
LABEL="scsi_start"
ATTRS{type}=="1", GROUP="tape"
----- ADD THE NEXT LINE: vvv
ATTRS{type}=="8", GROUP="tape"
----- ADD THE PREVIOUS LINE: ^^^
ATTRS{type}=="5", GROUP="cdrom"
ATTRS{type}=="6", GROUP="scanner"
ATTRS{type}=="3", ATTRS{vendor}=="HP", GROUP="scanner"
ATTRS{type}=="3", ATTRS{vendor}=="Epson", GROUP="scanner"
LABEL="scsi_end"
Hope it's useful for someone of you.
Greetings from Germany,
Chris
