In udevadm info /dev/sda, why are different ata values provided and which one is the preferred/more accurate address?
...
N: sda
S: disk/by-path/pci-0000:00:1f.2-ata-1.0
...
E: DEVPATH=/devices/pci0000:00/0000:001f.2/ata3/host2/target2:0:0/2:0:0:0/block/sda
...
E: ID_ATA=1
...
I see that the by-path is ...ata-1.0 but the DEVPATH has it as .../ata3/... and the ID_ATA is 1
I would assume that the most accurate way to target a device is /dev/disk/by-path/... but I am not understanding the variations in the ata value.
