This command requests that the device identifier information in the logical unit be 
set to the value received in the SET DEVICE IDENTIFIER parameter list. 
On successful completion of this command a unit attention shall be generated for 
all initiators except the one that issued the service action. When reporting the unit 
attention condition the additional sense code shall be set to DEVICE 
IDENTIFIER CHANGED. 
The "Service Action" field can be specified only X'06'. 
The "Allocation Length" field specifies the length in bytes of the Identifier that 
shall be transferred from the application client to the device server. The maximum 
value for this field shall be 512 bytes. A parameter list length of zero indicates 
that no data shall be transferred, and that subsequent REPORT DEVICE 
IDENTIFIER commands shall return an Identifier length of zero. Logical units 
that implement this command shall be capable of accepting a parameter list length 
of 512 bytes or less. If the parameter list length exceeds 512 bytes and the logical 
unit is not capable of storing the requested number of bytes, then the device server 
shall return CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid 
field in CDB [=24-00]). 
The SET DEVICE IDENTIFIER parameter lists are shown in Table 4.93.
