SET DEVICE IDENTIFIER Command (A4h)
The SET DEVICE IDENTIFIER command requests that the device identifier
information in the logical unit be set to the value send via the SET DEVICE
IDENTIFIER command’s parameter list.
Upon successful completion of a SET DEVICE IDENTIFIER command, a Unit
Attention is generated for all initiators except the one that issued the command.

. Any other value forces Check Condition, Illegal
Request.
Parameter List Length
This field specifies the length, in bytes, of the Identifier to be
transferred from the application client to the device server. The
maximum value for this field is 64 bytes. A parameter list length
of 0 indicates that no data will be transferred, and that
subsequent REPORT DEVICE IDENTIFIER commands will return an
Identifier length of 0. If the parameter list length exceeds 64
bytes, then the drive returns a Check Condition status with the
sense key set to Illegal Request, and an additional sense code of
Invalid Field in CDB.
