The "Identifier Length" field specifies the length in bytes of the "Identifier" field.
If the "Allocation Length" field in the CDB is too small to transfer all of the identifier, the length
shall not be adjusted to reflect the truncation. The identifier length shall initially equal zero, and
shall be changed only by a successful SET DEVICE IDENTIFIER command.
The "Identifier" field shall contain a vendor specific value. The value reported shall be the last
value written by a successful SET DEVICE IDENTIFIER command. The value of the identifier
shall be changed only by a SET DEVICE IDENTIFIER command. The identifier value shall
persist through resets, power cycles, media format operations, and media replacement.
The target shall return the same Identifier to all initiators on all ports.
The execution of a REPORT DEVICE IDENTIFIER may require the enabling of a nonvolatile
memory within the logical unit. If the nonvolatile memory is not ready, the device server shall
return CHECK CONDITION status, rather than wait for the device to become ready. The sense
key shall be set to NOT READY and the additional sense data shall be set as described in the
TEST UNIT READY command.
