Each identification descriptor (see table 89) contains information
identifying the logical unit, physical device, or access path used by
the command and returned parameter data. The association field
indicates the entity that the identification descriptor describes. If a
physical or logical device returns the identification descriptor with
the association field set to 0h, it shall return the same descriptor when
it is accessed through any other path.
