Good evening,
my final solution: SUBSYSTEM=="scsi_generic", SUBSYSTEMS=="scsi", ATTRS{type}=="8", ATTRS{model}=="MAGNUM 224 ", IMPORT{program}="scsi_id --sg-version=3 --export --whitelisted -d $devnode", \ SYMLINK+="changer0"
SUBSYSTEM=="scsi_generic", SUBSYSTEMS=="scsi", ATTRS{type}=="8", ATTRS{model}=="FlexStor II ", ATTRS{rev}=="5.11", IMPORT{program}="scsi_id --sg-version=3 --export --whitelisted -d $devnode", \ SYMLINK+="changer1"
SUBSYSTEM=="scsi_generic", SUBSYSTEMS=="scsi", ATTRS{type}=="8", ATTRS{model}=="FlexStor II ", ATTRS{rev}=="5.50", IMPORT{program}="scsi_id --sg-version=3 --export --whitelisted -d $devnode", \ SYMLINK+="changer2"
Very helpful:
/dev/sch0, /dev/sch1, /dev/sch2 are persistent devices - but not generic devices.
udevadm info -a /dev/sch0 shows all possible attributes in the udev rules key format.
best regards
Helmut

Hello Ron,
sounds good. I have 2 tape changer. I persume, udev creates the same link for both.
Can I modify SYMLINK+="changer-$env{ID_SERIAL}"
The serial should be unique.

I've taken you as far as I can go. Now you will have to experiment a bit for your use case. I should point out that at least in my system, the link with the serial number in it shows up even with the line commented in the rules file.
As always, YMMV.
Maybe
.... ATTRS{serial}=="likethis16c07338d2a294c" , SYMLINK+="mybackup/changer1" ...
and for the second one
... ATTRS{serial}=="likethis9ae76c073f5ccb8" , SYMLINK+="mybackup/changer2" ...
?
