Command Specifications
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 list are shown below.
