  ==========
  Intrepid SRU

  Impact of the bug:

  multipath uses /lib/udev/scsi_id to obtain a unique path identifier.
  However the options of scsi_id have changed. Thus multipath doesn't
  work as expected.

  How the bug has been addressed:

  The options used to call scsi_id have been updated.

  TEST CASE:

  Potential regression:
  This patch fixes the default call which wasn't working before. Users that implemented the workaround in their configuration file shouldn't see any changes.
