Table 117 -- REPORT DEVICE IDENTIFIER command Bit Byte 7 6 5 4 3 2 1 0 0 1 2 3 4 5 6 7 8 9 (MSB) Reserved OPERATION CODE (A3h) SERVICE ACTION (05h) Reserved RESTRICTED ALLOCATION LENGTH (LSB) Reserved CONTROL Restricted Reserved SCC-2 defines specific usages for bytes 4 and 5, and bit 1 in byte 10, however these fields are reserved for the REPORT DEVICE IDENTIFIER command defined by this standard. The REPORT DEVICE IDENTIFIER parameter data (see table 118) contains a four-byte field that contains the length in bytes of the parameter data and the logical unit's identifier. Table 118 -- REPORT DEVICE IDENTIFIER parameter data Bit Byte 0 3 4 n IDENTIFIER 7 6 5 4 3 2 1 0 (MSB) IDENTIFIER LENGTH (N-3) (LSB) 146 SCSI Commands Reference Manual, Rev. A IDENTIFIER LENGTH field The IDENTIFIER LENGTH field indicates the length in bytes of the IDENTIFIER field. The relationship between the IDENTIFIER LENGTH field and the CDB ALLOCATION LENGTH field is defined in 2. 1. 4. 5. The identifier length shall initially equal zero, and shall be changed only by a successful SET DEVICE IDENTIFIER command. IDENTIFIER field 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 logical unit resets, I_T nexus losses, media format operations, and media replacement. The logical unit shall return the same identifier to all application clients. Processing a REPORT DEVICE IDENTIFIER may require the enabling of a nonvolatile memory within the logical unit. If the nonvolatile memory is not ready, the command shall be terminated with CHECK CONDITION status, rather than wait for the nonvolatile memory to become ready. The sense key shall be set to NOT READY and the additional sense code shall be set as described in table 12. This information should allow the application client to determine the action required to cause the device server to become ready. SCSI Commands Reference Manual, Rev. A 147 3. 36 REPORT LUNS command The REPORT LUNS command (see table 119) requests that the peripheral device logical unit inventory accessible to the I_T nexus be sent to the application client. The logical unit inventory is a list that shall include the logical unit numbers of all logical units having a PERIPHERAL QUALIFIER value of 000b (see table 47). Logical unit numbers for logical units with PERIPHERAL QUALIFIER values other than 000b and 011b may be included in the logical unit inventory. Logical unit numbers for logical units with a PERIPHERAL QUALIFIER value of 011b shall not be included in the logical unit inventory. Table 119 -- REPORT LUNS command Bit Byte 7 6 5 4 3 2 1 0 0 1 2 3 4 5 6 7 8 (MSB) OPERATION CODE (A0h) Reserved SELECT REPORT Reserved ALLOCATION LENGTH (LSB) Reserved CONTROL The SELECT REPORT field (see table 120) specifies the types of logical unit addresses that shall be reported. Table 120 -- SELECT REPORT field Code Description The list shall contain the logical units accessible to the I_T nexus with the following addressing methods (see SAM-3): 00h a b c Logical unit addressing method, Peripheral device addressing method; and Flat space addressing method. If there are no logical units, the LUN LIST LENGTH field shall be zero. 01h 02h 03h - FFh The list shall contain only well known logical units, if any.
