[Solved] udev rules: serial for persistent device naming disappeared

Question

Hello,
since the latest upgrade of udev and kmod I cant't mount my external e-SATA hard disk with my working udev rules.
This is my udev rule:
$ cat /etc/udev/rules.d/66-persistent_esata.rules
KERNEL=="sd?1", SUBSYSTEMS=="block", ENV{ID_SERIAL_SHORT}=="S1VSJ1LS301247", NAME="aluguard"
When plugged in, I could decrypt and mount it with "sudo cryptsetup luksOpen /dev/aluguard aluguard && mount /mnt/aluguard".
Since the update above I get "Device /dev/aluguard doesn't exist or access denied."
While I re-checked https://wiki.archlinux.org/index.php/Ma … _with_udev, I discovered, that the serial entry in the output of udevadm has vanished:
$ udevadm info -a -p $(udevadm info -q path -n /dev/sdg)
Udevadm info starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

What is the reason for this strange behaviour, and how can I get back the serial entry?
Thank in advance!

OK, there is the serial.... but the problem persists - udev doesn't execute the rule and doesn't create /dev/aluguard.
