Logical units should report all these device identifiers:
a) logical unit name. In NAA binary format, EUI-64-based binary format,
or string name format - whatever is convenient based on the protocol(s)
of the target port(s). A FCP-only or SAS-only target uses NAA format
(64-bit or 128-bit).
b) relative target port identifier of the target port used for the
INQUIRY command. Should even be returned on a single-ported target.
c) target port identifier or name of the target port used for the
INQUIRY command. In NAA binary, EUI-64 binary, or string name format, as
defined by the transport protocol. An FCP or SAS target uses a 64-bit
NAA format (the FC port WWN or the SAS address).
d) target device name. Ideally a single name in string name format (may
be "naa.", "eui.", or "iqn." based). Could also be a set of device
names, one per target port protocol, each in NAA binary, EUI-64-based
binary, or string name formats.
