udev rules for Logitec LHR-4BNHEU3

This project provides udev rules for Logitec LHR-4BNHEU3.

The udev has /lib/udev/rules.d/60-persistent-storage.rules script. It provides Persistent Device Naming as below.

$ ls -l /dev/disk/by-id
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:0 -> ../../sdb
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:1 -> ../../sdc
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:2 -> ../../sdd
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:3 -> ../../sde

Unfortunately, AAAA is the serial number of LHR-4BNHEU3. It is not persistent device naming based on identifier of the HDD.

So, this project provides persistent device naming based on identifier of the HDD as below.

$ ls -l /dev/disk/by-id
ata-TOSHIBA_DT01ACA300_BBBBBBBBB -> ../../sdb
ata-TOSHIBA_DT01ACA300_CCCCCCCCC -> ../../sdc
ata-TOSHIBA_DT01ACA300_DDDDDDDDD -> ../../sdd
ata-TOSHIBA_DT01ACA300_EEEEEEEEE -> ../../sde
usb-Logitec_LHR-4BNHEU3_000000000000AAAA-0:0 -> ../../sdb
usb-Logitec_LHR-4BNHEU3_000000000000AAAA-0:1 -> ../../sdc
usb-Logitec_LHR-4BNHEU3_000000000000AAAA-0:2 -> ../../sdd
usb-Logitec_LHR-4BNHEU3_000000000000AAAA-0:3 -> ../../sde
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:0 -> ../../sdb
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:1 -> ../../sdc
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:2 -> ../../sdd
usb-TOSHIBA_DT01ACA300_000000000000AAAA-0:3 -> ../../sde
usb-TOSHIBA_DT01ACA300_BBBBBBBBB -> ../../sdb
usb-TOSHIBA_DT01ACA300_CCCCCCCCC -> ../../sdc
usb-TOSHIBA_DT01ACA300_DDDDDDDDD -> ../../sdd
usb-TOSHIBA_DT01ACA300_EEEEEEEEE -> ../../sde
wwn-0xFFFFFFFFFFFFFFFF -> ../../sdb
wwn-0xGGGGGGGGGGGGGGGG -> ../../sdc
wwn-0xHHHHHHHHHHHHHHHH -> ../../sdd
wwn-0xIIIIIIIIIIIIIIII -> ../../sde

This makes to be able to refer HDD identity with lsblk as below:

$ # Result of `lsblk` by default udev rule
$ lsblk -o name,model,serial,wwn,hctl,tran,subsystems,rev,vendor
