[Bug 1217030] Re: udev IMPORT{builtin}="path_id" returns wrong value

[Martin Pitt]

This was "fixed" upstream and in saucy by dropping the by-path symlinks
for drives which are not "real" SCSI but actually ATA drives through the
pata driver:
http://git.kernel.org/cgit/linux/hotplug/udev.git/commit/?id=481dcf7c8f
has the rationale.

So this is "fixed" or "wontfix", I'm afraid.

Title:
  udev IMPORT{builtin}="path_id" returns wrong value

Status in “udev” package in Ubuntu:
  Fix Released

Bug description:
  /lib/udev/rules.d/60-persistent-storage.rules has the line:
   ENV{DEVTYPE}=="disk", DEVPATH!="*/virtual/*", IMPORT{builtin}="path_id"

  This function is suppose to return a unique "PATH" to a particular port that a device is plugged into.  Instead it is reporting the PCI address and a made up scsi ID:
    pci-0000:00:11.0-scsi-0:0:0:0

  It reports the same value for all 5 active SATA drives in the system.
  At the time of this report, one drive is removed for RMA, but all
  drives were getting the same value.

  udevadm info -a reports the following for the different drives:
    /devices/pci0000:00/0000:00:11.0/ata1/host0/target0:0:0/0:0:0:0/block/sda
    /devices/pci0000:00/0000:00:11.0/ata3/host2/target2:0:0/2:0:0:0/block/sdb
    /devices/pci0000:00/0000:00:11.0/ata4/host3/target3:0:0/3:0:0:0/block/sdc
    /devices/pci0000:00/0000:00:11.0/ata6/host5/target5:0:0/5:0:0:0/block/sr0

  To verify I ran: 
    udevadm test /block/sdc
  and then ls -l /dev/disk/by-path/
    pci-0000:00:11.0-scsi-0:0:0:0 -> ../../sdc
  Running:
    udevadm test /block/sda 
  results in:
    pci-0000:00:11.0-scsi-0:0:0:0 -> ../../sda
