[Bug 575297] Re: path_id is not implemented for SAS drives

[stevecs]

I see the exact same thing here with LSI HBA's (9200-8E's/LSI2008 chipset) on numerous external drives under 10.04.2LTS


complete strace output and udevadm attached.

Bug description:
  Binary package hint: casper

  Version: 1.236

  Normally casper will search all HDD's for a livefs allowing a recovery
  partition to be recognized.  In the scenario that a HDD is hooked up
  to a SAS controller, it appears that casper is not recognizing it as a
  valid device.

  Looking at the udevadm info output, ID_PATH is not being set for this
  device, which casper appears to depend upon.
