In linux there is also a move away from the host_number,
channel_number, target_identifier and LUN tuple used
traditionally by many Unix SCSI subsystems (most do not
have the second component: channel_number). At least the
LUN is not controversial (as long as it is 8 byte!). The
target_identifier is actually transport dependent (but
could just be a simple enumeration). The host_number is
typically an enumeration over PCI addresses but some
other type of computer buses (e.g. microchannel) could be
involved.
For some transports, not only the channel but also the Scsi_Host is
meaningless. Such transports deal only with targets and logical units.
This includes all multi-protocol + multi-bus or network infrastructures
such as iSCSI, USB, IEEE 1394.
