reflect the truncation. The identifier length shall initially equal zero, and shall be changed only by a
successful SET DEVICE IDENTIFIER command (see Section 8.48).
[b] 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.
[5] See Table 61, "CONTROL field," in Section 7.2.1.
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 (see Section 8.53). This information
should allow the application client to determine the action required to cause the device server to become ready.
